AbstractAbstract PDF
Background
In Malaysia, occupational allergic contact dermatitis (ACD) is often under-reported. This case report describes a chemical engineer who developed possible ACD, likely due to workplace allergen exposure.
Case presentation
He presented with a 4-month history of intensely itchy rashes on both hands, which improved during work breaks. A dermatological examination revealed lichenified, pruritic papules with well-defined borders on the palmar surfaces of both hands. A skin patch test identified reactions to five allergens, including ‘fragrance mix,’ ‘methyldibromo glutaronitrile,’ ‘clioquinol,’ ‘epoxy resin,’ and ‘textile dye mix.’ However, among these, only ‘bisphenol A diglycidyl ether,’ a component of ‘epoxy resin,’ was listed in the safety data sheet as a confirmed occupational exposure. In accordance with local regulations, this case was reported as ‘occupational dermatitis’ to the Department of Occupational Safety and Health. The patient was prescribed symptomatic topical treatments, including emollients and topical corticosteroids. Additionally, he was advised to switch to hypoallergenic products. On follow-up, his chronic inflammatory skin lesions showed improvement.
Conclusions
Thorough occupational history-taking and patch testing are essential for diagnosing ACD. Personalized health education and regular follow-ups, is crucial in monitoring lesion resolution and evaluating the effectiveness of preventive measures in workplace settings.

AbstractAbstract AbstractAbstract in Korean PDFSupplementary Material
Background
The Korean Occupational Stress Scale (KOSS) was developed in 2004. During this time, industrial structures have evolved, and societal awareness of occupational stress has changed. This study aims to develop and validate a revised version of the Korean Occupational Stress Scale (KOSS®19), tailored for workers, reflecting these changes.
Methods
The KOSS®19 was developed based on the 26-item KOSS–short form (SF) through a review by eight experts. A survey was conducted including 359 service industry workers, comprising the KOSS®19, Burnout, and Depression scales. The KOSS®19 subscales were restructured, and their reliability and validity were evaluated.
Results
The KOSS®19 composed of eight subscales: hazardous physical environment (2 items), high job demand (3 items), insufficient job control (2 items), low social support (2 items), job insecurity (2 items), organizational injustice (4 items), lack of reward (2 items), and work-life imbalance (2 items). The reliability and validity of the KOSS®19 were found to be satisfactory.
Conclusions
The KOSS®19 is a suitable tool for assessing occupational stress, effectively replacing the original KOSS and KOSS-SF.

Da-Yee Jeung, Hyoung Ryoul Kim, Hansoo Song, Inah Kim, Jin-Ha Yoon, Sang-Baek Koh, Sung-Soo Oh, Hee-Tae Kang, Dae-Sung Hyun, Chunhui Suh, Sei-Jin Chang
Ann Occup Environ Med 2025;37:e14.   Published online May 7, 2025
DOI: https://doi.org/10.35371/aoem.2025.37.e14
AbstractAbstract AbstractAbstract in Korean PDFSupplementary Material
Background
Workplace violence refers to any act or threat of physical violence, verbal abuse, harassment, intimidation, bullying, mobbing, or other aggressive and disruptive behaviors that occur at work. This study aims to develop and validate a revision of the Korean Workplace Violence Scale (KWVS®13), based on the first edition of the Korean Workplace Violence Scale (KWVS-24), and to provide practical applications and guidelines for the Korean workplace environment.
Methods
The revised KWVS®13 was developed by restructuring the 24-item KWVS through a review process involving eight experts. To validate the reliability and validity of KWVS®13, a self-administered survey comprising KWVS®13, burnout, and depression scales was conducted among 359 service industry workers. KWVS®13 was reclassified, and its reliability and validity were assessed. Receiver operating characteristic curve analysis was performed to establish sex-specific cutoff values (normal vs. risk) of the scale.
Results
KWVS®13 consists of 13 items across four subscales: “psychological and sexual violence from customers” (4 items), “psychological and sexual violence from supervisors or coworkers” (4 items), “physical assault from customers, supervisors, or coworkers” (2 items), and “organizational protective system for workplace violence” (3 items). We found that KWVS®13 shows relatively good validity (content validity ratio for content validity: 0.888; success rate of item convergent and discriminant validity: 100%, and significant correlation coefficient with burnout (r = 0.115–0.83, p < 0.05) and depression (r = 0.098–0.348, p < 0.05) with the exception of Organizational Violence Protection System for Workplace Violence) and reliability (Cronbach’s alpha: 0.827–0.860). The reference values for determining risk groups according to the intensity of exposure to workplace violence are presented separately by sex.
Conclusions
KWVS®13 is a robust and useful measurement tool to objectively and quantitatively assess the intensity and magnitude of workplace violence. It incorporates important considerations for workplace violence assessment and provides a reliable framework for evaluating workplace violence in various professional settings.

Sangjun Choi, Ju-Hyun Park, Inah Kim, Jungwon Jang, Jeehee Min, Sang Baek Koh, Seongwon Kim, Yeji Sung, Kyoung Yoon Ko, Su Min Oh, Un-Yeol Jeon
Ann Occup Environ Med 2025;37:e10.   Published online April 28, 2025
DOI: https://doi.org/10.35371/aoem.2025.37.e10
AbstractAbstract AbstractAbstract in Korean PDFSupplementary Material
Background
This study aimed to develop standard job categories for constructing a job-exposure matrix (JEM) for police officers in South Korea and to evaluate their applicability.
Methods
We examined standard job codes related to police personnel management and compared them with job classifications from police publications. Using R Shiny, we developed a web-based search tool for standard codes. A pilot survey of 130 police officers assessed the codes' applicability and relevance to health-related hazardous factors.
Results
Eighty-seven standard functional codes used in the police personnel management system POOL were organized into minor categories as the basic units of standard jobs. These were grouped into 20 sub-major categories and further consolidated into 10 major categories to develop the standard job codes. The responses to the standard job codes in the pilot survey were 75% accurate compared with the final expert evaluation results and 99.2% accurate compared with the algorithm-based automatic allocation results. The results of the job-hazardous factor network analysis revealed that the most frequently reported hazardous factor was emotional labor, followed by night shifts and electromagnetic waves. Emotional labor was identified as the top hazardous factor in six out of the nine standard job categories.
Conclusions
The standard job codes developed in this study were designed in connection with the personnel management system for police officers, making them well-suited for constructing a comprehensive JEM for the entire police force.
경찰관 직무-노출 매트릭스 구축을 위한 표준직무 코드 개발
목적
본 연구는 한국 경찰관에 대한 직무-노출 매트릭스(JEM) 구축을 위해 표준직무 코드를 개발하고 적용 가능성을 평가하고자 실시되었다.
방법
경찰관 인사관리 시스템을 검토하고, 경찰청 공식 발간물 및 조직도상의 직무관련 분류 체계를 검토하였다. R Shiny를 활용하여 웹 기반 표준코드 검색기를 개발하였고, 130명의 경찰관을 대상으로 시범 설문을 통해 경찰관들이 표준직무 코드를 잘 선택하는지 평가하였다. 또한 소속 부서 및 기능 등의 기술내용을 활용하여 표준직무 코드를 자동할당 하는 알고리즘을 만들어 자동할당 가능성을 평가하였다.
결과
경찰관 인사관리 시스템에서 활용 가능한 직무 관련 정보를 검토한 결과 87개의 기능코드를 기반으로 20개의 중분류, 10개의 대분류 표준직무 코드를 개발하였고, 웹 기반 검색기 링크(https://kscf.shinyapps.io/pff_app/)를 통해 자세한 국문 코드명과 설명을 확인하고, 코드 검색이 가능하도록 하였다. 시범 설문 결과 응답자들의 표준직무 코드 선택 정확도는 75.4% 였고, 자동할당 결과의 정확도는 99.2%였다. 직무-유해요인 설문조사 결과 가장 많이 응답한 유해요인은 감정노동이었고, 다음으로 야간근무, 전자기파 순이었다.
결론
본 연구에서 개발한 표준직무 코드는 경찰관의 인사시스템과 연동되어 경찰관 전체에 대한 JEM 구축에 잘 활용될 수 있을 것으로 기대되며, 향후 표준직무 코드를 적용한 경찰관 건강영향 관련 전수 설문조사를 통해 JEM 구축을 실시할 예정이다.

DOI: https://doi.org/10.35371/aoem.2025.37.e13
AbstractAbstract AbstractAbstract in Korean PDFSupplementary Material
Background
Emotional labor refers to the management of emotions and expressions to meet the emotional requirements of a job role. This study aimed to develop a revised version of the Korean Emotional Labor Scale (KELS®11), based on the first edition (KELS-24) introduced in 2014, and to provide practical applications and guidelines for its use in the Korean workplace through a validation process.
Methods
The revised version of KELS®11 was derived from the 24-item KELS, following a review process involving eight experts. To validate the scale’s reliability and validity, a self-administered survey was conducted among 359 service industry workers using KELS®11, burnout, and depression scales. KELS®11 was reclassified, and its reliability and validity were evaluated. Receiver operating characteristic curve analysis was conducted to establish sex-specific cutoff values (normal vs. high-risk groups).
Results
KELS®11 was designed to account for individual, organizational, and cultural contexts. It consists of four subscales and 11 items: “emotional regulation” (2 items), “emotional dissonance” (3 items), “organizational monitoring” (2 items), and “organizational protective system for emotional labor” (4 items). KELS®11 demonstrated good validity (content validity ratio: 0.84; item convergence/discriminant validity success rates: 100%; correlation with burnout: r = 0.185–0.436, p < 0.01; correlation with depression: r = 0.128–0.339, p < 0.05) and reliability (Cronbach’s alpha: 0.597–0.795). Additionally, sex-specific reference values were established to determine risk groups based on the intensity of emotional labor exposure.
Conclusions
KELS®11 is a validated and reliable measurement tool designed to assess the intensity and magnitude of emotional labor in the workplace. The revised tool reflects critical considerations in the development of emotional labor measurement scales.

Chiara Pucci, Luca Tomassini, Marco dell’Omo, Alessandra Deini, Daniele Lillacci, Cristiana Gambelunghe, Mauro Zampolini, Nicola Murgia, Angela Gambelunghe
Ann Occup Environ Med 2025;37:e15.   Published online May 26, 2025
DOI: https://doi.org/10.35371/aoem.2025.37.e15
AbstractAbstract PDF
Background
Lead poisoning is a serious public health issue that can arise from various sources, including nonoccupational exposure. This can make it challenging to manage, as lead poisoning can arise from unexpected sources. This case study examined lead poisoning in a 52-year-old man linked to hobbyist activities involving lead pellets, highlighting the diagnostic and therapeutic challenges associated with this uncommon source of exposure.
Case presentation
A 52-year-old man with a history of sports fishing presented with confusion, balance disorders, and memory loss. The initial medical evaluation revealed anemia and elevated lead levels. Further investigations, including imaging and blood tests, confirmed the presence of ingested lead pellets. The patient underwent chelation therapy, which led to a reduction in blood lead levels and improvement in symptoms. Follow-up over 46 months showed a gradual decrease in lead levels and partial recovery of cognitive function, although a few lead-related effects persisted.
Conclusions
This case underscores the need for awareness of non-traditional sources of lead exposure, such as hobbyist activities. Effective diagnosis and treatment, including chelation therapy, can significantly alleviate the effects of lead poisoning. Ongoing monitoring is essential to manage long-term health outcomes related to chronic lead exposure.

DOI: https://doi.org/10.35371/aoem.2025.37.e2
Correction in: Ann Occup Environ Med 2025;37(0):e16
AbstractAbstract AbstractAbstract in Korean PDFSupplementary Material
A comprehensive list of occupational diseases among farmers is crucial for both compensation and prevention efforts. In Korea, most farmers are self-employed, and some occupational diseases are compensated through farmer safety insurance. However, it is not harmonized with industrial accident compensation insurance and does not adequately reflect the true burden of occupational diseases among farmers. To address this gap, the authors compiled a list of occupational diseases tailored to Korean farmers by reviewing the International Labor Organization’s list of occupational diseases, the Korean Industrial Accident Compensation Insurance List, the occupational disease lists of other countries, and relevant literature on farmers’ work-related diseases.
한국 농업인의 직업성 질병 목록: 문헌고찰
농업인의 직업병에 대한 포괄적인 목록은 질병보상과 예방을 위해 중요하다. 한국에서 농업인의 대부분은 자영업자로 근로자에게 적용되는 산업재해보상보험의 적용을 받지 못하고 일부 직업성질환에 대해서만 정책보험인 농업인안전보험을 통해 보상되고 있다. 그러나 이러한 보상은 산업재해보상보험과 조화를 이루지 못하고 있으며, 농업인에게 실제 부담을 주고 있는 직업성 질병을 반영하지 못하고 있다. 이러한 문제를 개선하기 위해 저자들은 국제노동지구의 직업병 목록, 한국의 산업재해보상보험법 상 업무관련성 질병 목록, 다른 국가들의 직업병 목록 및 농업인의 업무관련성 질병에 대한 문헌을 검토하여, 한국 농업인에게 적합한 직업병 목록을 작성하였다.

Occupational disease issues in high-tech industries of South Korea: analysis of governmental data on the semiconductor and display industries
Chungsik Yoon, Jinjoo Chung, Jongran Lee, Kwonchul Ha, Joseph DiGangi, Jeong-Ok Kong
Ann Occup Environ Med 2025;37:e6.   Published online March 24, 2025
DOI: https://doi.org/10.35371/aoem.2025.37.e6
AbstractAbstract AbstractAbstract in Korean PDF
Background
This study analyzed occupational diseases compensated through the government system in the Korean electronics industry and observed changes in the rationale for compensation.
Methods
Data from the Korea Workers’ Compensation and Welfare Service (KWCWS) from 2012 to 2023 were analyzed to examine occupational disease issues in South Korea's semiconductor and display industries.
Results
KWCWS received 174 occupational disease claims between 2012 and 2023, with 88 (50.6%) approved. The case of a 22-year-old semiconductor worker who died from leukemia has raised awareness and appears to be leading to more claims and higher approval rates. Cancer-related claims, particularly for breast and blood cancers, were the most common. Since 2018, the approval rate for occupational diseases has increased to 60%, which may have been influenced by the Supreme Court's Principle of Presumption of Occupational Diseases and the government’s reduction of the burden of proof. However, approval rates remain lower in small- and medium-sized enterprises (38.0%) compared to large corporations (55.6%), likely because of better documentation and unionization in the latter. The semiconductor industry had more claims and approvals than the LCD industry, primarily due to its longer operational history and greater chemical exposure.
Conclusions
In South Korea, the increasing approval rate of occupational diseases in the electronics industry from 2012 to 2023 appears to reflect changes in how causal relationships and occupational health policies have been implemented and this is likely due to stakeholder involvement and relevant legal decisions.
반도체 및 디스플레이 산업의 정부자료 분석으로 본 한국 첨단 산업에서의 직업병 이슈
목적
본 연구는 한국 전자산업에서 산재보험 보상 승인된 직업병을 분석하고 보상 근거의 변화를 관찰하였다.
방법
2012년부터 2023년까지 근로복지공단의 데이터를 분석하여 한국의 반도체 및 디스플레이 산업에서 직업병의 신청과 승인을 연도별, 업종별, 규모별로 분석하였다.
결과
2012년부터 2023년까지 근로복지공단에 접수된 직업병 산재보상 신청은 174건이고 이 중 88건(51%)이 승인되었다. 2007년 한 반도체 노동자의 백혈병 사망을 계기로 직업병에 대한 인식이 높아져, 산재보상 신청 건수가 증가하고 승인률도 높아진 것으로 추정된다. 신청 상병은 암, 특히 유방암과 혈액암이 가장 많았다. 대법원이 직업병 추정 원칙을 판시하고 정부가 입증 부담을 완화한 것이 2018년 이후 직업병 승인률을 60%까지 증가하는데 기여하였다. 그러나 중소기업(38%)의 승인률은 대기업(56%)에 비해 여전히 낮은데, 이는 대기업에서 기록을 더 잘 보관하고 노조 조직률도 더 높은 것이 영향을 주었을 것이다. 반도체 산업은 LCD 산업보다 산재 신청 건수와 승인 건수가 더 많은데, 이는 반도체 산업의 역사가 더 길며 화학물질 노출이 더 크기 때문으로 추정된다.
결론
연구 기간 동안 전자업체에서의 대부분 직업병은 혈액암과 유방암과 같은 암이었고 직업병 산재 승인의 증가는 이해관계자의 참여와 사회 이슈화, 유연해진 법원 판결, 산재보험제도 등이 큰 영향을 미쳤을 것이다.

DOI: https://doi.org/10.35371/aoem.2025.37.e5
AbstractAbstract AbstractAbstract in Korean PDFSupplementary Material
Background
Humans are exposed to mercury primarily in its highly toxic form, methyl mercury, which is known to have adverse effects on various organs and systems. The negative impact of mercury exposure on the growth, development, and mental health of children, from infancy to adolescence, is well-documented. However, there are no internationally standardized safe limits for mercury exposure. This study investigated the impact of dietary habits and higher body mass index (BMI) on blood mercury levels in adolescents.
Methods
This study analyzed the data from the 4th Korean National Environmental Health Survey (KoNEHS) 2018–2020. The focus was on 825 middle and high school students aged 13–18 years, whose blood mercury levels were measured. A survey on dietary and lifestyle habits was also conducted. Blood mercury levels were categorized by geometric median values, and associations with overweight status and seafood consumption were examined using a generalized linear model.
Results
The geometric mean blood mercury level for the entire sample was 1.37 μg/L, with levels of 1.31 μg/L in normal-weight individuals and 1.43 μg/L in overweight individuals, showing a statistically significant difference between the two groups. After adjusting for other variables, blood mercury levels were significantly associated with overweight status (estimate: 0.084; p = 0.018; 95% confidence interval [CI]: 0.015–0.153), consumption of large fish and tuna more than once a week (estimate: 0.18; p = 0.001; 95% CI: 0.077–0.284), and consumption of fish once a week or more (estimate: 0.147; p = 0.004; 95% CI: 0.043–0.250).
Conclusions
In adolescents, a higher BMI and an increased consumption of large fish, tuna, and fish were associated with higher blood mercury levels. Notably, a stronger association was found between large fish consumption and blood mercury levels in the overweight group. These findings suggest the need to moderate seafood consumption and establish more proactive mercury exposure standards for adolescents.
한국 청소년에서 체중 및 식습관과 높은 혈중 수은 농도의 연관: KNHANES 제4기 데이터, 2018-2020
목적
수은은 독성이 강한 형태인 메틸 수은의 상태로 인간에게 주로 노출된다. 메틸 수은은 발달 및 정신건강측면을 포함한 인체 전반에 독성 영향이 있지만 현재 국제적으로 표준화된 수은 노출 기준이 없다. 특히나 영유아나 청소년은 발달이 아직 이루어지지 않아 성인에 비해 더 수은 노출의 위험도가 높다. 본 연구에서는 청소년의 식습관이나 과체중 여부가 혈중 수은 노출에 미치는 영향을 조사하였다.
방법
본 연구는 국립환경과학원에서 발간하는 제4기 국민환경보건 기초조사(2018-2020)를 활용하였다. 제4기 대상 중 혈중 수은 농도가 측정 된 13-18세의 중, 고등학생 825명을 대상으로 하였고 식습관이나 생활 습관에 대한 개인 설문을 활용하였다. 혈중 수은 농도 중위 값을 기준으로 구분하여 과체중 여부를 구분하여 각종 해산물 식습관과 혈중 수은 농도와의 연관성을 로지스틱 회귀 모델을 사용하여 조사하였고, 이 후 전체 연구 대상자를 대상으로 연관성을 조사하였다.
결과
전체 표본의 기하평균 혈중 수은 농도는 1.37 µg/L로, 정상체중 군은 1.31 µg/L, 과체중 군은 1.43 µg/L로 나타났으며, 두 군 간에 통계적으로 유의미한 차이가 있었다. 다른 변수들을 조정한 후, 혈중 수은 농도는 과체중 상태(추정값: 0.084; p-value: 0.018; 95% 신뢰구간[CI]: 0.015-0.153), 주 1회 이상 대형어류와 참치 섭취(추정값: 0.18; p-value: 0.001; 95% CI: 0.077-0.284), 주 1회 이상 어류 섭취(추정값: 0.147; p-value: 0.004; 95% CI: 0.043-0.250)와 유의미한 관계가 있었다.
결론
청소년에서 높은 BMI와 대형어류, 참치, 어류 섭취가 높은 혈중 수은 농도와 관련이 있었다. 특히, 과체중 그룹에서는 대형어류 섭취와 혈중 수은 농도 간의 강한 연관성이 발견되었다. 이 결과는 청소년을 위한 해산물 섭취 절제와 더 적극적인 수은 노출 기준 설정이 필요함을 시사한다.

DOI: https://doi.org/10.35371/aoem.2025.37.e9
AbstractAbstract AbstractAbstract in Korean PDF
Background
In August 2021, three female semiconductor workers applied for occupational disease compensation due to congenital diseases diagnosed in their children: patient A (immunoglobulin A nephropathy, vesicoureteral reflux, renal agenesis), patient B (renal agenesis, esophageal atresia with tracheoesophageal fistula), and patient C (congenital megacolon). The Occupational Safety and Health Research Institute (OSHRI) initially assessed the relatedness of these conditions to occupational exposure as low. However, the Occupational Disease Adjudication Committee of the Korea Workers’ Compensation and Welfare Service (KWCWS) overturned this assessment, officially recognizing these cases as occupational diseases in March 2024—the first such recognition in South Korea.
Case presentation
The mother of Patient A worked in optical processes for 9 years, the mother of patient B worked in diffusion processes for 10 years, and the mother of patient C worked in molding and inspection processes for 7 years. Their jobs involved exposure to benzene, organic solvents, pyrolysis products, ionizing radiation, and X-rays. All three women continued working during pregnancy, and none had a family history of related illnesses.
Conclusions
OSHRI estimated that the occupational exposure levels of these workers were low and noted insufficient reproductive research focused on congenital anomalies in the Korean semiconductor industry before 2010. However, KWCWS cited frequent miscarriages among female semiconductor workers as indirect evidence of an increased risk of congenital anomalies. KWCWS ultimately concluded that substantial evidence supports an association between occupational exposure and congenital diseases in the children of female semiconductor workers. This case series highlights a landmark recognition of occupational disease related to congenital anomalies in the semiconductor industry, emphasizing the need for further reproductive health research and improved worker protections.
업무상질병판정위원회에서 업무상 질병으로 인정한 반도체 여성 노동자 자녀의 선천성 질환 사례 3건
배경
최근 3명의 여성 반도체 노동자가 자녀들의 선천성 질환에 대해 산업재해 질환 보상을 신청하였다: 노동자 자녀 A는 면역글로불린 A 신병증, 방광요관 역류, 무신장증을, 노동자 자녀 B는 무신장증 및 기관식도루를 동반한 식도 폐쇄증을, 그리고 노동자 자녀 C는 선천성 거대결장을 진단받았다. 산업안전보건연구원(OSHRI)은 반도체 산업에서의 직업적 노출과 이들 선천성 질환 간의 관련성이 낮다고 결론지었다. 그러나 근로복지공단(KWCWS)은 이 사례들을 직업병으로 인정하였다. 이에 본 연구는 2024년 3월 국내 최초로 직업병으로 인정된 여성 반도체 노동자 자녀의 선천성 질환 사례 3건을 보고하고자 한다.
증례
환자 A의 어머니는 9년 동안 광학 공정에서 근무했으며, 환자 B의 어머니는 10년 동안 확산 공정에서 근무하였다. 환자 C의 어머니는 7년 동안 성형 및 검사 공정에서 근무하였다. 이들의 업무는 벤젠, 유기 용제, 열분해 생성물, 이온화 방사선, X선 등에 노출되는 작업을 포함하고 있었다. 세 여성 모두 임신 중에도 계속 근무했으며, 관련 질환의 가족력은 없었다.
결론
산업안전보건연구원의 역학조사평가위원회는 세 노동자의 직업적 노출 평가 수준이 낮다고 평가했으며, 2010년 이전 한국 반도체 산업 내 생식 관련 연구가 부족하다고 판단하였다. 그러나 근로복지공단의 질병판정위원회는 여성 반도체 노동자들 사이에서 빈번히 보고된 유산이 자녀들에게 선천성 기형의 위험 증가를 간접적으로 입증하는 증거로 작용한다고 판단하였다. 근로복지공단 질병판정위원회는 여성 반도체 노동자의 직업적 노출과 자녀의 선천성 질환 사이의 연관성을 뒷받침하는 상당한 증거가 있다고 결론지었다. 이러한 사례 연구는 반도체 산업에서 선천성 기형과 관련된 직업병 인식의 중요한 전환점을 보여주며, 생식 건강 연구의 확대와 근로자 보호 강화를 위한 필요성을 강조한다.

AbstractAbstract AbstractAbstract in Korean PDFSupplementary Material
Background
PM2.5 (particulate matter less than 2.5 μm) causes various health problems. Recent studies suggest that long-term exposure to PM2.5 may have a negative impact on vision. This study examined the effects of long-term exposure to concentrations of PM2.5 exceeding Korean standards on myopia prevalence.
Methods
This study was conducted on adults aged 40–69 years. The PM2.5 concentrations were calculated as the 1–5-year moving averages based on the participants' residential areas. The relationships between the PM2.5 levels, categorized by the annual average concentration standard in Korea, and the prevalence of myopia were analyzed using binary logistic regression. The results were evaluated using the 95% confidence interval.
Results
PM2.5 concentrations averaged over 1–3 years were not significantly associated with the prevalence of myopia. On the other hand, the prevalence of myopia was significantly higher in areas where the 4–5-year moving average PM2.5 levels exceeded the Korean standards. These findings suggest that long-term exposure to PM2.5 may have a detrimental effect on vision.
Conclusions
This study revealed the impact of long-term PM2.5 exposure on the prevalence of myopia, highlighting the importance of managing PM2.5 levels. Nevertheless, further cohort studies focusing on adults and in-depth research into the effects of long-term exposure will be necessary.
장기 PM2.5 노출과 근시 유병률 간의 관계: 국민건강영양조사-대기오염 연계자료, 2020
목적
초미세먼지(PM2.5)는 다양한 건강 문제를 유발하며, 특히 장기 노출이 시력에 부정적인 영향을 미칠 수 있다는 연구가 제기되고 있다. PM2.5는 염증 반응과 산화 스트레스를 유발하여 눈 조직에 손상을 줄 수 있으며, 이는 근시를 포함한 다양한 안구 질환과 관련이 있다. 기존 연구는 주로 학령기 아동을 대상으로 했으나, 최근 연구에서는 40세 이상의 성인에서도 PM2.5 노출이 근시 유병률에 영향을 미칠 가능성이 제시되었다. 한국의 PM2.5 연간 기준은 15㎍/㎥로, WHO 기준보다 3배 높으나 이에 기반한 연구는 드물다. 본 연구는 한국의 PM2.5 기준을 바탕으로 성인의 근시 유병률과의 관계를 장기적으로 분석하였다.
방법
연구는 2020년 국민건강영양조사-대기오염 연계자료를 활용해 진행되었으며, 대상은 40-69세 성인이다. 연구 참여자의 거주지에서 PM2.5 농도의 1년-5년 이동평균을 계산하고, 이를 한국 연간 기준인 15㎍/㎥를 기준으로 나누어 분석했다. 근시는 자동굴절검사를 통해 정의되었으며, 이분형 로지스틱 회귀분석으로 근시 유병률과 PM2.5 농도의 관계를 평가했다. 혼란 변수로 성별, 연령, 교육 수준, 음주 및 흡연 여부 등이 포함되었으며, SPSS를 사용해 통계 분석을 진행했다. 분석 결과는 오즈비(odds ratio)와 95% 신뢰구간으로 제시되었다.
결과
PM2.5의 1년-3년 이동평균은 근시 유병률과 유의미한 관계를 보이지 않았으나, 4년-5년 이동평균이 기준치를 초과한 지역에서는 근시 유병률이 유의미하게 증가했다. 5년 이동평균 PM2.5 농도의 오즈비는 4.038(95% CI: 1.295-12.595)로 나타나, 장기 노출이 근시 발생 위험을 크게 높이는 것으로 확인되었다.
결론
본 연구는 장기간 PM2.5 노출이 근시 유병률에 미치는 누적 손상 효과를 규명하며, 특히 4년-5년 이상의 노출이 중요한 요인임을 밝혔다. 이는 기존 연구와 달리 한국의 PM2.5 기준을 적용하여 현실적이고 특화된 결과를 도출한 점에서 의미가 있다. PM2.5 노출은 염증 반응과 산화 스트레스를 통해 안구 건강에 악영향을 미치며, 이는 성인뿐만 아니라 다양한 연령층에서도 고려해야 할 문제다. 단면 연구로 인과관계를 확정할 수는 없지만, 대기 오염 관리와 장기 코호트 연구의 필요성을 강조한다. 후속 연구에서는 다양한 대기오염 물질의 복합적인 영향을 분석해야 할 필요가 있다.

AbstractAbstract AbstractAbstract in Korean PDF
The Korean Work, Sleep, and Health Study (KWSHS) was launched in 2022 as a longitudinal panel study to examine the interactions between work conditions, sleep health, and labour market performance among the Korean workforce. Baseline data were collected from 5,517 participants aged 19 to 70, encompassing diverse occupations. Follow-up surveys occur biannually, accommodating seasonal variations in sleep and health dynamics. To ensure stability, refreshment samples were integrated in later waves, maintaining a cohort size of 5,783 participants in wave 5. Key data include socio-demographics, employment characteristics, sleep patterns, health outcomes, and workplace performance. Early findings highlight critical associations, such as the adverse effects of occupational physical activity on productivity, the impact of emotional labour on health-related productivity loss, and the significance of sleep disruptions on mental health. The cohort’s design enables detailed analyses of longitudinal and cross-sectional trends, offering insights into how changing work environments influence health and productivity. The KWSHS could serve as a vital resource for evidence-based interventions aimed at improving occupational health and productivity in Korea's evolving labour landscape. Data access is available through the study’s principal investigator upon request.
한국 직업, 수면 및 건강 연구(KWSHS)
한국 직업, 수면 및 건강 연구(KWSHS)는 한국 노동자의 근로 조건, 수면 건강, 노동 시장 성과 간 상호작용을 조사하기 위해 2022년에 시작된 종단적 패널 연구이다. 기초 자료는 다양한 직업군을 포함하여 19세에서 70세까지의 5,517명을 대상으로 수집하였다. 후속 설문조사는 수면 및 건강 역학의 계절적 변동성을 고려하여 2년마다 실시하며, 코호트의 안정성을 유지하기 위해 후속 조사에서는 보충 표본을 추가하여 5차 웨이브에서는 총 5,783명의 코호트 규모를 유지하였다. 주요 자료에는 사회인구학적 정보, 고용 특성, 수면 패턴, 건강 결과 및 직장 성과 등이 포함된다. 초기 연구 결과는 직업적 신체활동이 생산성에 미치는 부정적 영향, 감정 노동이 건강 관련 생산성 손실에 미치는 영향, 그리고 수면 장애가 정신 건강에 미치는 중요성을 포함한 주요 연관성을 강조하고 있다. 본 코호트의 설계는 종단적 및 횡단적 추세에 대한 세부적인 분석을 가능하게 하여 변화하는 근로 환경이 건강 및 생산성에 미치는 영향을 심층적으로 이해할 수 있게 한다. KWSHS는 한국의 변화하는 노동 환경 속에서 직업 건강 및 생산성을 향상시키기 위한 근거 기반 개입을 위한 중요한 자원이 될 수 있다. 데이터 접근은 연구 책임자에게 요청을 통해 가능하다.

Hoje Ryu, Seong-Sik Cho, Jung Il Kim, Sun-Haeng Choi, Nathan Kim
Ann Occup Environ Med 2025;37:e4.   Published online February 19, 2025
DOI: https://doi.org/10.35371/aoem.2025.37.e4
AbstractAbstract AbstractAbstract in Korean PDFSupplementary Material
Background
Commuting is essential for working life; however, prolonged travel times can negatively affect health, particularly musculoskeletal pain. This study aims to examine the relationship between commuting time and musculoskeletal pain (back, upper extremity, and lower extremity pain), in the context of working time.
Methods
This cross-sectional study used data from the Sixth Korean Working Conditions Survey conducted in Korea between October 2020 and April 2021. Variables such as commuting time, weekly working hours, and shift work were assessed using the survey questions. Musculoskeletal pain was determined based on self-reported pains in the previous year. The covariates included demographics, employment status, ergonomic risks, and job stress. The association between commuting time and musculoskeletal pain stratified by weekly working hours or shift work was analyzed by survey-weighted logistic regression analysis.
Results
This study found a significant association between longer commuting times and increased prevalence of musculoskeletal pain, particularly back, upper extremity, and lower extremity pain. When commuting time was ≤60, 61–120, >120 minutes, the odds ratio was 1.00, 1.33 (95% confidence interval [CI]: 1.16–1.52), and 2.41 (95% CI: 1.77–3.29) for back pain; 1.00, 1.29 (95% CI: 1.13–1.46), and 2.27 (95% CI: 1.71–3.00) for upper extremity pain; and 1.00, 1.24 (95% CI: 1.05–1.45), and 1.53 (95% CI: 1.13–2.08) for lower extremity pain, respectively. Furthermore, except for upper extremity pain, this trend was amplified when participants were concurrently exposed to long working hours, and for lower extremity pain, this trend was aggravated among shift workers.
Conclusions
Long commuting time may be a risk factor for musculoskeletal pain, and its’ effects could be aggravated when combined with long working hours or shift work. This study observed the detrimental impact of prolonged commuting on musculoskeletal health, particularly among employees with extended working hours or shift work.
노동 시간 및 교대근무 여부에 따른 통근 시간과 근골격계 통증의 연관성
목적
통근 시간은 업무에 필수적인 요소이며 긴 통근 시간은 건강에 부정적인 영향을 미칠 수도 있다. 이 연구에서는 통근 시간과 근골격계 통증(허리, 상지 및 하지 통증)의 연관성을 노동 시간(장시간 노동 및 교대근무)을 고려하여 조사하였다.
방법
이 연구는 제6차 취업자근로환경조사의 자료를 이용하였다. 통근 시간, 주당 근무 시간, 교대근무 여부는 설문조사를 통해 조사하였다. 근골격계 통증은 지난 1년간 자가 보고된 건강 문제를 통해 평가하였다. 공변량에는 인구통계학적 요인, 고용 상태, 인간공학적 요인 및 직업 스트레스 요인이 포함되었다. 통근 시간과 근골격계 통증과의 연관성을 주당 근무시간 또는 교대근무 여부에 따라 계층화하여 다중 로지스틱 회귀분석을 이용하여 분석하였다.
결과
통근 시간이 60분 이하, 61~120분, 120분 이상일 때 요통에 대한 odds ratio는 1.00, 1.33(95% confidential interval [CI]: 1.16-1.52), 2.41(95% CI: 1.77-3.29); 상지 통증은 1.00, 1.29(95% CI: 1.13-1.46), 2.27(95% CI: 1.71-3.00); 하지 통증은 1.00, 1.24(95% CI: 1.05-1.45), 1.53(95% CI: 1.13-2.08)이었다. 또한 상지 통증을 제외하고는 장시간 노동을 병행하는 경우 오즈비가 증가하는 경향과 하지 통증의 경우 교대 근무자에서 증가되는 경향이 관찰되었다.
결론
긴 통근시간은 근골격계 통증의 위험 요인이 될 수 있으며, 장시간 노동이나 교대근무에 동시에 노출되면 해로운 영향이 증가될 수 있다. 본 연구의 결과는 긴 통근시간이 근골격계 건강에 해로운 영향을 미칠 수도 있다는 점을 보여주며, 특히 장시간 노동이나 교대근무를 하는 근로자 집단에서 그 영향이 커질 수 있음을 시사한다.

Perspectives from the new president of the Korean Society of Occupational and Environmental Medicine: future strategies for occupational and environmental medicine
Sang Baek Ko
Ann Occup Environ Med 2025;37:e1.   Published online February 19, 2025
DOI: https://doi.org/10.35371/aoem.2025.37.e1
AbstractAbstract AbstractAbstract in Korean PDF
Modern Korean society is experiencing fundamental transformations in industrial structures and working environments driven by complex factors, including demographic shifts, the Fourth Industrial Revolution, the coronavirus disease 2019 pandemic, and digital transformation. The evolving dynamics between the manufacturing and service industries, the emergence of technology-driven sectors, and the proliferation of new occupational categories are reshaping traditional employment models. This has directed the labor market toward nonstandard employment forms, including temporary, contract-based, and platform labor. Consequently, issues such as employment instability and reduced accessibility to workplace health programs, including occupational safety training, health examinations, and workplace health management, have become increasingly prominent. Although occupational and environmental medicine has subsequently gained significance, the current occupational health and safety framework inadequately addresses the nuances of emerging labor forms. Legal gaps persist, leaving vulnerable groups such as nonregular workers, platform laborers, and older workers insufficiently protected under existing systems. Furthermore, systemic issues are evident in the inadequate follow-up care during occupational health examinations, lacking continued adherence to hazard-centric approaches, and insufficient attention to chronic diseases and mental health challenges. This study proposes strategies that occupational and environmental medicine can address these issues. First, legal and institutional reforms must encompass new labor forms, accompanied by modernized safety and health guidelines. Second, state-of-the-art technologies should be leveraged to enhance predictive disease management and personalized healthcare for workers. Third, a preventive approach integrating chronic disease management, mental healthcare, and psychosocial risk factors must be established. Fourth, fostering interdisciplinary research collaboration across medicine, engineering, and psychology is essential for developing practical solutions to emerging challenges. In conclusion, occupational and environmental medicine in Korea must adapt to effectively address the evolving labor landscape. Through systematic innovation, integrated health-management approaches, technological advancements, and interdisciplinary cooperation, the health and safety of all workers in the rapidly changing world can be ensured.
대한직업환경의학회 신임회장의 제언: 직업환경의학의 미래 전략
현대 한국 사회는 인구구조 변화, 4차 산업혁명, 팬데믹, 디지털 전환 등 복합적인 요인에 의해 산업 구조와 근로 환경에서 근본적인 변화를 경험하고 있다. 제조업과 서비스업 간의 역학 변화, 기술 중심 산업의 부상, 새로운 직업군의 확산은 전통적인 고용 모델을 재편하고 있다. 이에 따라 노동 시장은 비정규직, 계약직, 플랫폼 노동과 같은 비표준 고용 형태로 이동하고 있다. 그 결과, 고용 불안정과 직업 안전 교육, 건강검진, 작업장 건강관리 등 직업 건강 프로그램에 대한 접근성 저하 문제가 점점 더 부각되고 있다.
이러한 변화로 직업환경의학의 중요성이 증대되었으나, 현재의 직업 건강 및 안전 체계는 새로운 노동 형태의 특성을 충분히 반영하지 못하고 있다. 법적 공백이 여전히 존재하며, 비정규직 근로자, 플랫폼 노동자, 고령 노동자 등 취약 계층은 기존 제도 아래에서 충분히 보호받지 못하고 있다. 또한, 건강검진 후 사후관리의 미비, 유해 요인 중심 접근의 지속적 적용 부족, 만성 질환 및 정신 건강 문제에 대한 관심 부족 등 체계적 문제가 드러나고 있다.
본 연구는 직업환경의학이 이러한 문제를 해결하기 위한 전략을 제안한다. 첫째, 새로운 노동 형태를 포괄하는 법적·제도적 개혁과 현대화된 안전 및 건강 지침의 도입이 필요하다. 둘째, 최첨단 기술을 활용하여 예측적 질병 관리와 근로자 맞춤형 건강관리를 강화해야 한다. 셋째, 만성 질환 관리, 정신 건강 관리, 심리사회적 위험 요인을 통합하는 예방적 접근을 확립해야 한다. 넷째, 의학, 공학, 심리학 등 학제 간 연구 협력을 통해 새로운 과제에 대한 실질적 해결책을 모색해야 한다. 결론적으로, 한국의 직업환경의학은 변화하는 노동 환경에 효과적으로 대응하기 위해 적응해야 한다. 체계적 혁신, 통합적 건강 관리 접근법, 기술적 발전, 학제 간 협력을 통해 빠르게 변화하는 세계에서 모든 근로자의 건강과 안전을 보장할 수 있을 것이다.

Sex difference in musculoskeletal disabilities among Korean fishers: a cross-sectional study
Hye-min Kim, Soo Hyeong Park, Bong Gyun Joo, Ki-Soo Park, Jeong Ho Kim, Hansoo Song
Ann Occup Environ Med 2025;37:e18.   Published online July 7, 2025
DOI: https://doi.org/10.35371/aoem.2025.37.e18
AbstractAbstract AbstractAbstract in Korean PDF
Background
Fishing is a physically demanding occupation with a high risk of musculoskeletal disabilities (MSDs). Although previous studies have focused on ergonomic risk factors, little attention has been paid to sex differences in the prevalence of MSDs among fishers. This study aimed to assess whether female fishers experience a higher prevalence of MSDs than male fishers and to examine whether this difference persists after adjusting for socioeconomic and occupational factors.
Methods
We analyzed cross-sectional data from 898 Korean fishers (513 men and 385 women) who participated in the 2021–2022 Fisher Health Survey. MSDs in the upper extremities, lower back, and knees were defined as scores in the top 25% of the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH), Oswestry Disability Index, and Western Ontario and McMaster Universities Arthritis Index Short Form (WOMAC-SF), respectively. Modified Poisson regression was used to calculate the prevalence ratios (PRs) by sex, with stepwise adjustments for age, socioeconomic factors, and occupational factors.
Results
Female fishers had significantly higher MSD risk than male fishers across all body regions (fully adjusted PRs: upper extremity, 1.59; lower back, 1.63; knee, 1.44). Sex disparities were most pronounced among those under 60 years of age and remained significant even in older age groups.
Conclusions
The elevated MSD risk among female fishers persisted despite adjusting for conventional risk factors, suggesting the influence of additional factors such as biological susceptibility, domestic labor, and gendered health reporting. Therefore, MSD prevention strategies should include sex-sensitive multidimensional approaches beyond ergonomic interventions.
한국 어업인에서의 근골격계 장애의 성별 차이: 단면 연구
배경

어업은 육체적으로 힘든 직업으로 근골격계 장애의 위험이 높습니다. 기존 연구들은 주로 인간공학적 위험요인에 집중해 왔으나, 어업인의 근골격계 장애 유병률에 대한 성별 차이는 상대적으로 덜 주목받아 왔습니다. 본 연구는 여성 어업인이 남성 어업인보다 근골격계 장애 유병률이 더 높은지를 평가하고, 이러한 차이가 사회경제적 및 직업적 요인을 보정한 후에도 지속되는지를 살펴보았습니다.
방법

2021–2022년 어업인 건강조사에 참여한 한국 어업인 898명(남성 513명, 여성 385명)의 단면 자료를 분석하였습니다. 상지, 요추, 무릎의 근골격계 장애는 각각 QuickDASH, ODI, WOMAC-SF 점수 상위 25%에 해당할 경우로 정의하였습니다. 수정된 포아송 회귀(modified Poisson regression)를 사용하여 성별에 따른 유병비를 산출하였으며, 연령, 사회경제적 요인, 직업적 요인 순으로 단계적으로 보정하였습니다.
결과

여성 어업인은 남성 어업인보다 모든 신체 부위에서 근골격계 장애의 위험이 유의하게 높았습니다(보정 유병비: 상지 1.59, 요추 1.63, 무릎 1.44). 성별 격차는 60세 미만 집단에서 가장 두드러졌으며, 고령 집단에서도 유의한 차이가 지속되었습니다.
결론

여성 어업인의 높은 근골격계 장애의 위험은 잘 알려진 위험요인을 보정한 후에도 유지되었으며, 이는 생물학적 취약성, 가사노동, 성별에 따른 건강보고 차이 등의 추가적인 요인이 작용했을 가능성을 시사합니다. 따라서 근골격계 장애 예방 전략은 인간공학적 개입을 넘어 성 감수성을 가져야 하며, 다차원적으로 접근해야 합니다.

Ann Occup Environ Med 2024;36:e22.   Published online August 28, 2024
DOI: https://doi.org/10.35371/aoem.2024.36.e22
AbstractAbstract PDFSupplementary Material
Background
The banking sector is one of the job sectors that experience high stress, workload, complex interpersonal relationships, and job burnout as it involves interaction with the public and financial responsibilities, which leads to high burnout and stress. The present study was conducted to assess the prevalence of burnout and stress among bank employees and to find the associated factors.
Methods
This cross-sectional survey was conducted among 282 bank employees of Kollam district, Kerala, India. Data was collected using a self-administered questionnaire related to the socio-demographic and professional details. We used the Oldenburg Burnout Inventory (OLBI) to screen for burnout levels. Depression Anxiety Stress Scale (DASS 21) to screen for the levels of depression, anxiety, and stress among study participants. Descriptive statistics were used to summarize the data, and logistic regression was used to identify the factors associated with the levels of burnout and stress.
Results
Of 282 study participants, moderate to high levels of burnout were observed in 232 participants (82.2%), and 74 participants (26.2%) had mild to extremely severe levels of stress. Daily average working duration showed an association with higher levels of burnout (adjusted odds ratio [ORAdj]: 2.391; 95% confidence interval [CI]: 1.12–5.10) and stress (ORAdj: 3.37; 95% CI: 1.58–7.16).
Conclusions
A high prevalence of burnout and stress was observed in the present study. The duration of working hours was associated with both burnout and stress. Therefore, regulating the working hours may help adequately manage stress and burnout, thereby improving the mental health of bank employees.

Injury rates and work-related diseases following workforce reduction among South Korean on-site workers in basic local governments between 2016 and 2018
Dongwhan Suh, Nahyun Kim, Han-Na Jung, Woo Chul Jeong, Hyunjoo Kim
Ann Occup Environ Med 2025;37:e17.   Published online July 28, 2025
DOI: https://doi.org/10.35371/aoem.2025.37.e17
AbstractAbstract AbstractAbstract in Korean PDFSupplementary Material
Background
South Korean on-site workers in the public sector, fully covered by the Occupational Safety and Health Act, often perform hazardous tasks. However, their status and injury rates remain poorly documented. This study aimed to analyze changes in injury rates and the proportion of work-related diseases (WRDs) among on-site workers in basic local governments (BLGs) following workforce reductions between 2016 and 2018.
Methods
Data from two sources provided by the Ministry of Employment and Labor were analyzed: organizational data on the number of on-site workers, and cases of injuries, deaths, and diseases among on-site workers in 226 BLGs from 2016 to 2018; and workers’ compensation claims data (individual data) for on-site workers in BLGs during the same period. Injury, mortality, and disease incidence rates were calculated and compared between BLGs with increased and decreased workforce. The proportion of WRDs among all the injuries was also examined.
Results
The total number of on-site workers in BLGs decreased by 18.1% in 2018 compared with 2016. The injury rate increased from 0.46% in 2016 to 0.62% in 2018. BLGs with workforce reductions showed higher injury rates, particularly in those with fewer than 1,000 on-site workers. The proportion of WRDs among all injuries increased by 1.34 times in 2018 compared with 2016.
Conclusions
Workforce reductions among on-site workers in BLGs are associated with higher injury rates and a great proportion of WRDs. These findings highlight the need for improved occupational safety and health practices within the public sector and serve as an important basis for establishing workforce management and injury prevention policies. However, limitations in the available data made it challenging to identify worker groups particularly vulnerable to WRDs. Further research is needed, as it is critical for the development of effective occupational safety and health policies.
한국 기초자치단체 현업업무 종사자의 인력감소에 따른 재해율 및 작업관련질병 구성비 변화: 2016 - 2018년 산업재해 승인 자료 분석
Background: 산업안전보건법의 전면 적용 대상인 공공행정 기관의 현업업무 종사자들은 종종 위험한 업무를 수행하고 있으나, 이들의 현황과 이들이 겪는 재해에 대해서는 잘 알려져 있지 않다. 본 연구는 2016년부터 2018년까지 기초자치단체 현업업무 종사자에서의 인력 감소 이후 재해율 및 작업관련질병 구성비의 변화를 분석하고자 하였다.
방법
고용노동부에서 제공한 2가지 자료를 분석하였다: (1) 2016년부터 2018년까지 226개 기초자치단체 현업업무 종사자 수, 재해자 수, 사망자 수, 질병 이환자 수를 포함한 조직 수준 자료, (2) 2016년부터 2018년까지 기초자치단체 현업업무 종사자의 산업재해 승인 자료 (개별 수준 자료). 이를 통해 재해율, 사망률, 질병 이환율을 산출하고, 전년 대비 근로자 수 증감에 따라 기초자치단체를 구분하여 두 집단 간 이러한 수치를 비교하였다. 또한, 전체 산업재해 중 작업관련질병의 구성비도 분석하였다.
결과
2018년 기초자치단체 현업업무 종사자 수는 2016년 대비 18.1% 감소하였다. 재해율은 2016년 0.46%에서 2018년 0.62%로 증가하였다. 전년 대비 현업업무 종사자 수가 감소한 기초자치단체에서의 재해율은 전년 대비 증가한 기초자치단체에서의 재해율보다 더 높았으며, 이는 현업업무 종사자 수가 1,000명 미만인 기초자치단체에서 더 두드러졌다. 전체 산업재해 중 작업관련질병의 구성비는 2016년에 비해 2018년에 1.34배 증가하였다.
결론
기초자치단체의 현업업무 종사자 수 감소는 재해율 및 작업관련질병 구성비 증가와 관련이 있다. 본 연구 결과는 공공부문 현업업무 종사자의 산업안전보건에 대한 인식을 제고하고, 향후 인력관리 및 재해 예방 정책 수립을 위한 기초자료로 활용될 수 있다. 다만, 원 자료의 한계로 인해 작업관련질병에 특히 취약한 근로자 집단을 구체적으로 파악하는 데는 어려움이 있었다. 이는 산업안전보건 정책 수립 시 중요한 문제이므로 향후 추가적인 연구가 필요하다.

Minjun Kim, Yangho Kim, A Ram Kim, Woon Jung Kwon, Soyeoun Lim, Woojin Kim, Cheolin Yoo
Ann Occup Environ Med 2024;36:e2.   Published online January 31, 2024
DOI: https://doi.org/10.35371/aoem.2024.36.e2
AbstractAbstract AbstractAbstract in Korean PDFSupplementary Material
Background

Cooking oil fumes (COFs) from cooking with hot oil may contribute to the pathogenesis of lung cancer. Since 2021, occupational lung cancer for individual cafeteria workers has been recognized in South Korea. In this study, we aimed to identify the distribution of lung-imaging reporting and data system (Lung-RADS) among cafeteria workers and to determine factors related to Lung-RADS distribution.

Methods

We included 203 female participants who underwent low-dose computed tomography (LDCT) screening at a university hospital and examined the following variables: age, smoking status, second-hand smoke, height, weight, and years of service, mask use, cooking time, heat source, and ventilation. We divided all participants into culinary and non-culinary workers. Binomial logistic regression was conducted to determine the risk factors on LDCT of Category ≥ 3, separately for the overall group and the culinary group.

Results

In this study, Lung-RADS-positive occurred in 17 (8.4%) individuals, all of whom were culinary workers. Binary logistic regression analyses were performed and no variables were found to have a significant impact on Lung-RADS results. In the subgroup analysis, the Lung-RADS-positive, and -negative groups differed only in ventilation. Binary logistic regression showed that the adjusted odds ratio (aOR) of the Lung-RADS-positive group for inappropriate ventilation at the workplace was 14.89 (95% confidence interval [CI]: 3.296–67.231) compared to appropriate ventilation as the reference, and the aOR for electric appliances at home was 4.59 (95% CI: 1.061–19.890) using liquid fuel as the reference.

Conclusions

The rate of Lung-RADS-positive was significantly higher among culinary workers who performed actual cooking tasks than among nonculinary workers. In addition, appropriate ventilation at the workplace made the LDCT results differ. More research is needed to identify factors that might influence LDCT findings among culinary workers, including those in other occupations.

한국 학교 급식소 종사자의 조리흄 노출과 Lung-RADS 분포
목적
2021년부터 한국에서는 개별 학교 급식 종사자의 폐암 산업재해가 인정되고 있다. 본 연구에서는 급식 종사자들의 Lung-imaging reporting and data system ( Lung-RADS ) 분포를 확인하고, Lung-RADS 분포와 관련된 요인을 탐색해보고자 한다.
방법
2020년도에 울산대학병원에서 저선량 CT를 촬영한 여성 참가자 중 203명을 대상으로 나이, 흡연 여부, 간접 흡연 여부, 키, 체중, 근무 년수, 마스크 착용 여부, 조리 시간, 열원, 환기방식 등의 변수를 조사하였다. 참가자를 조리직, 비조리직으로 분류하였다. 범주 3이상에 대한 영향을 확인하기 위해 이분형 로지스틱을 전체집단 조리직 집단에 나누어 실시하였다.
결과
Lung-RADS 양성은 17 (8.4%)명에게서 발생했고 모두 조리직에 해당했다. 이분형 로지스틱 회귀분석을 시행한 결과 전체집단에서 Lung-RADS 결과에 유의미한 영향을 주는 변수는 확인할 수 없었다. Subgroup 분석에서 Lung-RADS 양성, 음성군은 직장 내 환기방식에서만 차이가 있었다. 이분형 로지스틱 회귀분석 결과 직장에서 환기를 철저히 한 것을 참고치로 했을 때 부적절한 환기에 대한 Lung-RADS 양성의 오드비가 14.89이고 가정에서 액화연료 사용을 참고치로 했을 때 전기 요리기구 사용의 오드비는 4.59이였다.
결론
실제 조리업무를 시행하는 조리직의 경우 비조리직에 비해 Lung-RADS 양성 비율이 유의하게 높았다. 또한 조리실 환경에서 환기를 철저하게 하는 것이 Lung-RADS 소견에 영향을 주었다.

Min-Seok Kim, Juyeon Oh, Juho Sim, Byung-Yoon Yun, Jin-Ha Yoon
Ann Occup Environ Med 2023;35:e43.   Published online October 30, 2023
DOI: https://doi.org/10.35371/aoem.2023.35.e43
AbstractAbstract AbstractAbstract in Korean PDF
Background

Gig workers, also known as platform workers, are independent workers who are not employed by any particular company. The number of gig economy workers has rapidly increased worldwide in the past decade. There is a dearth of occupational health studies among gig economy workers. We aimed to investigate the association between exposure to violence and job stress in gig economy workers and depressive symptoms.

Methods

A total of 955 individuals (521 gig workers and 434 general workers) participated in this study and variables were measured through self-report questionnaires. Depressive symptoms were evaluated by the Patient Health Questionnaire-9 when the score was greater than or equal to 10 points. The odds ratio with 95% confidence interval was calculated using multivariable logistic regression adjusted for age, sex, working hours, education level, exposure to violence and job stress.

Results

19% of gig economy workers reported depressive symptoms, while only 11% of general workers reported the depressive symptoms. In association to depressive symptoms among gig economy workers, the mainly result of odds ratios for depressive symptoms were as follows: 1.81 for workers type, 3.53 for humiliating treatment, 2.65 for sexual harassment, 3.55 for less than three meals per day, 3.69 for feeling too tired to do housework after leaving work.

Conclusions

Gig economic workers are exposed to violence and job stress in the workplace more than general workers, and the proportion of workers reporting depressive symptoms is also high. These factors are associated to depressive symptoms. Furthermore, the gig workers associated between depressive symptoms and exposure to violence, job stress.

한국 긱경제 근로자에서 폭력 및 직무 스트레스 노출과 우울 증상관의 연관성
목적
긱경제 근로자 또는 플랫폼 근로자는 특정 회사에 고용되지 않은 독립적인 근로자들을 말한다. 긱경제는 그 규모가 커지고 있고, 종사하는 근로자들도 많아지고 있으나, 긱경제 노동자들의 산업 보건 연구가 부족한 실정이다. 우리는 긱경제 근로자에서 폭력 노출과 직무 스트레스에 노출되는 것이 우울 증상과 연관성이 있는지 조사하는 것을 목표로 했다.
방법
총 955명(긱 근로자 521명, 일반 근로자 434명)이 본 연구에 참여하였으며, 우울 증상은 PHQ-9(Patient Health Questionnaire-9) 점수가 10점 이상일 때로 평가하였다. 폭력 노출과 직무 스트레스는 자기보고식 설문지를 이용하여 측정하였다. 연령, 성별, 근무시간, 교육수준을 보정한 다변량 로지스틱 회귀분석을 이용하여 Odds Ratio, 95% Confidence Interval를 산출했다.
결과
긱 근로자의 19%가 우울 증상을 보고한 반면, 일반 근로자의 11%만이 우울 증상을 보고했습니다. 긱경제 근로자의 우울상과 관련하여 우울상 Odds ratio의 주요 결과는표3에서 ‘긱경제 근로자’ 1.89, ‘굴욕적 처우 경험’ 3.53, ‘성희롱 경험’ 2.65, ‘하루 세 끼 미만의 식사’ 3.55, ‘퇴근 후 집안일을 하기엔 너무 피곤함’ 3.69로 나타났다.
결론
긱경제 근로자는 일반 근로자에 비해 직장 내 폭력과 직무스트레스에 더 많이 노출되고, 우울 증상을 호소하는 근로자의 비율도 높다. 이러한 요인은 우울 증상과 관련이 있다. 더욱이, 긱경제 근로자들은 우울 증상과 폭력 노출, 직업 스트레스와 관련이 있다.

Associations of chronotype and insomnia with menstrual problems in newly employed nurses at university hospitals in the Republic of Korea
Han-Na Jung, Dongwhan Suh, Woo Chul Jeong, Jia Ryu, Yu-Mi Kim, Seohyun Yoon, Hyunjoo Kim
Ann Occup Environ Med 2023;35:e30.   Published online August 4, 2023
DOI: https://doi.org/10.35371/aoem.2023.35.e30
AbstractAbstract AbstractAbstract in Korean PDF
Background

Dysmenorrhea and menstrual cycle changes occur in women working shifts. Circadian rhythm disruption and sleep disturbances associated with shift work leads to health problems. We identified chronotypes and the occurrence of insomnia among newly employed university hospital nurses and investigated the association of these factors with menstrual problems.

Methods

We conducted pre-placement health examinations for shift workers using self-reported questionnaires between 2018 and 2020. A total of 463 nurses were included in the study. Sociodemographic data, shift work experience, and information on insomnia were collected from health examination data. In addition, details regarding chronotype, dysmenorrhea, irregular and abnormal menstrual cycles, amenorrhea, and contraceptive use were obtained from the questionnaire. Multiple logistic regression analysis was performed to study the association between chronotype, insomnia, and menstrual problems after controlling for age, body mass index, contraceptive use, amenorrhea, and prior shift work.

Results

The prevalence rates of dysmenorrhea, irregular menstrual cycles, and longer menstrual cycles were 23.8%, 14.9%, and 4.1%, respectively. The risk of dysmenorrhea increased in the evening-type (odds ratio [OR]: 3.209; 95% confidence interval [CI]: 1.685–6.113) and those with insomnia (OR: 1.871; 95% CI: 1.074–3.261). Additionally, the risk of an irregular menstrual cycle (OR: 2.698; 95% CI: 1.167–6.237) increased in the evening-type, and the risk of a longer menstrual cycle (OR: 4.008; 95% CI: 1.354–11.864) increased in individuals with insomnia.

Conclusions

Our findings suggest that dysmenorrhea is promoted in the evening-type and insomnia individuals. There may be an increased risk of irregular menstrual cycles among evening-type nurses and an increased risk of longer menstrual cycles among those with insomnia. Therefore, factors such as evening-type and insomnia should be considered for the prevention of menstrual problems in women performing shift work.

대학병원 신입 간호사에서 수면 관련 요인과 월경 건강과의 연관성
목적
이 연구는 간호사의 건강증진을 위한 효과적인 전략을 개발하는 데 있어 근거자료를 제공하는 것을 목적으로 하며, 구체적으로 일주기리듬 유형(크로노 타입) 및 불면 증상과 월경 건강 관련 문제들과의 연관성을 파악하였다.
방법
연구 대상자는 야간작업에 대한 배치 전 건강진단을 받은 두 개 대학병원에서 근무 중인 463명의 신규 간호사이다. 배치 전 건강진단 자료에서 연령, 체질량지수, 흡연, 음주, 운동 정도, 이전 교대 근무 경험 여부, 불면 증상에 대한 정보를 확보하였다. 일주기 리듬 유형, 피임방법 사용 여부, 무월경 경험, 월경통 및 월경주기의 규칙성과 간격에 대한 정보는 설문조사로 확인하였다. 연령, 체질량지수, 피임방법 사용 여부, 무월경 경험, 교대 근무 경험을 통제하여 일주기리듬 유형 및 불면 증상의 월경 건강 관련 문제들에 대한 위험비를 산출하기 위해 다중 로지스틱 회귀 분석을 수행하였다.
결과
월경곤란증, 불규칙한 월경주기, 긴 월경주기의 유병률은 각각 23.8%, 14.9%, 4.1%였다. 월경통에서 저녁형 일주기리듬 유형의 오즈비가 저녁형 외 일주기리듬 유형 그룹에 비해 3.209배(95% C.I. 1.685-6.113) 높았고, 불면 증상이 있다면 1.871배 (95% C.I. 1.074-3.261) 높았다. 또한 저녁형 일주기 리듬은 월경주기 간격이 불규칙한 경우에(오즈비 2.698 95% C.I. 1.167-6.237), 불면 증상이 있다면 40일 이상의 긴 월경 주기에(오즈비 4.008 95% C.I. 1.354-11.864) 각각 통계적으로 유의한 영향을 미치는 것을 확인하였다.
결론
우리 연구 결과로 저녁형 일주기리듬 유형 간호사에서 월경통과 불규칙 월경 이상이 관찰될 확률이 더 높고, 불면 증상이 있는 집단에서 월경통과 긴 월경주기가 증가할 가능성을 유추할 수 있다. 저녁형 일주기리듬과 불면 증상 같은 요인들은 여성 근로자의 월경 건강에 악영향을 미치는 경로를 연구하는 데 있어 고려해야 할 것들 중 하나가 될 수 있다.

Background

Accurate occupation classification is essential in various fields, including policy development and epidemiological studies. This study aims to develop an occupation classification model based on DistilKoBERT.

Methods

This study used data from the 5th and 6th Korean Working Conditions Surveys conducted in 2017 and 2020, respectively. A total of 99,665 survey participants, who were nationally representative of Korean workers, were included. We used natural language responses regarding their job responsibilities and occupational codes based on the Korean Standard Classification of Occupations (7th version, 3-digit codes). The dataset was randomly split into training and test datasets in a ratio of 7:3. The occupation classification model based on DistilKoBERT was fine-tuned using the training dataset, and the model was evaluated using the test dataset. The accuracy, precision, recall, and F1 score were calculated as evaluation metrics.

Results

The final model, which classified 28,996 survey participants in the test dataset into 142 occupational codes, exhibited an accuracy of 84.44%. For the evaluation metrics, the precision, recall, and F1 score of the model, calculated by weighting based on the sample size, were 0.83, 0.84, and 0.83, respectively. The model demonstrated high precision in the classification of service and sales workers yet exhibited low precision in the classification of managers. In addition, it displayed high precision in classifying occupations prominently represented in the training dataset.

Conclusions

This study developed an occupation classification system based on DistilKoBERT, which demonstrated reasonable performance. Despite further efforts to enhance the classification accuracy, this automated occupation classification model holds promise for advancing epidemiological studies in the fields of occupational safety and health.

DistilKOBERT를 기반으로 한 직업 분류 모델 개발: 제5차, 6차 한국근로실태조사를 이용하여
목적
정확한 직업분류는 정책 개발 및 역학 연구를 포함한 다양한 분야에서 중요하다. 본 연구는 자연어처리모델인 DistilKoBERT를 기반으로 한 직업 분류 모델을 개발하는 것을 목표로 한다.
방법
본 연구는 2017년과 2020년에 실시된 제5차와 제6차 근로환경조사 (KWCS)의 데이터를 활용하였다. 대한민국 근로자를 국가적으로 대표하는 총 99,665명의 참가자가 포함되었고, 직무 내용과 관련된 자연어 응답과 그에 맞는 대한민국 표준직업 분류코드(7차 개정, 3자리 코드)를 연구에 사용하였다. 데이터셋은 7:3의 비율로 훈련 및 테스트 데이터셋으로 무작위로 분할되었고, 사전 학습된 DistilKoBERT을 훈련 데이터셋을 통해 파인튜닝하여 모델을 학습시키고, 테스트 데이터셋을 사용하여 그 기능을 평가하였다. 정확도, 정밀도, 재현율 및 F1 점수가 평가 지표로 계산되었다.
결과
테스트 데이터셋의 28,996명의 참가자를 142개의 직업 코드로 분류한 최종 모델은 84.44%의 정확도를 보였다. 샘플 크기를 기준으로 가중치를 적용하여 계산한 모델의 정밀도, 재현율 및 F1 점수는 각각 0.83, 0.84 및 0.83 이었다. 최종 모델은 서비스, 판매 종사자 그룹에서 높은 정밀도를 보여주었지만 관리자 그룹에서는 낮은 정밀도를 보였다. 또한 훈련 데이터셋에서 표본의 수가 많았던 직업에서 대체로 높은 정밀도를 보였다.
결론
본 연구는 DistilKoBERT를 기반으로 합리적인 성능을 보이는 직업 분류 모델을 개발하였다. 분류의 정확성을 향상시키기 위한 추가적인 노력이 필요하지만, 자동화된 직업 분류 모델은 직업 안전 및 보건 분야의 유행병 연구를 발전시키는 데 기여할 것이라 기대된다.

Seok-Yoon Son, Jin-Young Min, Seung-Woo Ryoo, Baek-Yong Choi, Kyoung-Bok Min
Ann Occup Environ Med 2024;36:e21.   Published online August 6, 2024
DOI: https://doi.org/10.35371/aoem.2024.36.e21
AbstractAbstract AbstractAbstract in Korean PDFSupplementary Material
Background

The prevalence of multiple job-holding (MJH) is expected to show an upward trend among Korean workers, yet its potential impact on workers’ health remains poorly discussed. This study aimed to explore the association between MJH and experience of physical and psychological symptoms in various aspects among active Korean workers and to identify its differences depending on workers’ gender.

Methods

We conducted a population-based cross-sectional study among South Korean workers aged 15–59 using data from the 6th Korean Working Conditions Survey. The final study sample comprised 34,175 participants. MJH status and symptoms, such as musculoskeletal pain, headache or eyestrain, fatigue, insomnia, and anxiety, were measured by self-reported data. Logistic regression analyses were performed on the total sample and gender-stratified groups, with adjustments for the sociodemographic and occupational characteristics of the participants.

Results

One hundred thirty-five men and 103 women were defined as multiple job-holders (MJHers) among the study sample. When adjusted for sociodemographic and occupational characteristics, MJHers suffered more events of headache or eyestrain (odds ratio [OR]: 1.85, 95% confidence interval [CI]: 1.23–2.78) and anxiety (OR: 1.99, 95% CI: 1.05–3.79). Gender-stratified analyses with adjustment showed that among women workers, MJH was associated with musculoskeletal pain (OR: 1.85, 95% CI: 1.02–3.34), headache or eyestrain (OR: 2.53, 95% CI: 1.37–4.67), fatigue (OR: 2.38, 95% CI: 1.29–4.40), insomnia (OR: 1.92, 95% CI: 1.04–3.57), and anxiety (OR: 2.83, 95% CI: 1.11–7.20).

Conclusions

We found a significant association between MJH and various symptoms. Women MJHers were revealed to be a more vulnerable population than their men counterparts. Further research should account for the social context of MJH, and appropriate monitoring and intervention for maintaining the well-being of MJHers are needed.

한국인 근로자 집단에서의 다중직업종사와 육체적, 정신적 증상 간 연관성
목적
한 근로자가 동시에 두 개 이상의 직업을 가지는 행위인 ‘다중직업종사’ 현상은 한국인 근로자들 간 그 비중이 점차 증가할 것으로 전망된다. 그러나, 다중직업종사가 근로자의 다양한 육체적, 정신적 증상에 미칠 수 있는 영향에 대한 논의는 부족한 실정이다. 이에, 본 연구에서는 한국인 근로자 집단을 대상으로 하여 다중직업종사와 근로자의 건강 간 연관성을 다양한 관점에서 탐구하였다. 나아가 이러한 연관성이 근로자의 성별에 따라 관찰되는 차이에 대하여 확인하였다.
방법
본 연구는 제6차 근로환경조사 자료를 활용한 단면 연구로, 만 15세 이상 59세 이하인 한국인 근로자 34,175명을 대상으로 수행되었다. 다중직업종사 상태 및 육체적, 정신적 증상으로서 근골격계 통증, 두통 및 눈의 피로, 전신피로, 불면 및 불안의 유무는 자가 보고된 자료로 확인하였다. 연구대상 집단 전체 및 각 성별 집단을 대상으로, 근로자들의 인구사회학적 특성 및 직업 특성을 보정한 로지스틱 회귀분석을 시행하였다.
결과
연구대상 집단 중 135명의 남성과 103명의 여성이 다중직업종사자로 정의되었다. 인구사회학적 특성 및 직업 특성을 보정한 분석 결과 다중직업종사자에서 두통 및 눈의 피로 (OR 1.85, 95% CI 1.23-2.78)와 불안 (OR 1.99, 95% CI 1.05-3.79)의 위험이 더 큰 것으로 나타났다. 성별을 통한 층화 후 분석 결과 여성 근로자 집단에서 다중직업종사는 근골격계 통증 (OR 1.85, 95% CI 1.02-3.34), 두통 및 눈의 피로 (OR 2.53, 95% CI 1.37-4.67), 전신피로 (OR 2.38, 95% CI 1.29-4.40)와 불안 (OR 2.83, 95% CI 1.11-7.20) 간 유의한 연관성을 보였다.
결론
본 연구에서 다중직업종사와 근로자의 다양한 증상 간 유의한 연관성이 있음을 확인하였다. 다중직업종사의 건강 영향은 여성 근로자 집단에서 보다 저명한 것으로 나타났다. 후속 연구는 다중직업종사 현상에 대한 사회적 맥락을 보다 고려해야 할 것이다. 또한 다중직업종사자들의 건강 유지를 위한 모니터링 및 중재가 적절히 수행되어야 함을 제안한다.

Developing a short standard questionnaire for assessing work organization hazards: the Healthy Work Survey (HWS)
BongKyoo Choi, Youngju Seo
Ann Occup Environ Med 2023;35:e7.   Published online April 27, 2023
DOI: https://doi.org/10.35371/aoem.2023.35.e7
AbstractAbstract PDFSupplementary Material
Background

At present, no short standard questionnaire exists for assessing and comparing major work organization hazards in the workplaces of the United States.

Methods

We conducted a series of psychometric tests (content validity, factor analysis, differential-item functioning analysis, reliability, and concurrent validity) to validate and identify core items and scales for major work organization hazards using the data from the 2002–2014 General Social Surveys (GSSs), including the Quality of Worklife (QWL) questionnaire. In addition, an extensive literature review was undertaken to find other major work organization hazards which were not addressed in the GSS.

Results

Although the overall validity of the GSS-QWL questionnaire was satisfactory in the psychometric tests, some GSS-QWL items of work-family conflict, psychological job demands, job insecurity, use of skills on the job, and safety climate scales appeared to be weak. In the end, 33 questions (31 GSS-QWL and 2 GSS) were chosen as the least, but best validated core questions and included in a new short standard questionnaire (called the Healthy Work Survey [HWS]). And their national norms were established for comparisons. Furthermore, based on the literature review, fifteen more questions for assessing other significant work organization hazards (e.g., lack of scheduling control, emotional demands, electronic surveillance, wage theft) were included in the new questionnaire. Thus, the HWS includes 48 questions in total for assessing traditional and emerging work organization hazards, which covers seven theoretical domains: work schedule/arrangement, control, support, reward, demands, safety, and justice.

Conclusions

The HWS is a short standard questionnaire for assessing work organization hazards which can be used as a first step toward the risk management of major work organization hazards in the workplaces of the US.

Effect of psychosocial safety climate on work-family conflict and psychological health among working couples
Nurfazreen Aina Muhamad Nasharudin, Zhao Rui
Ann Occup Environ Med 2024;36:e27.   Published online October 25, 2024
DOI: https://doi.org/10.35371/aoem.2024.36.e27
AbstractAbstract PDFSupplementary Material
Background
The purpose of the study was to look into how work-family conflict (WFC), family-work conflict (FWC), and psychological health are affected by the psychosocial safety climate (PSC). First, the study suggested that for both husband and wife, PSC moderates the relationship between job demands and WFC. Second, the study predicted FWC mediates the relationship between WFC and depressive symptoms through the “crossover” process.
Methods
The study design used a multi-source sample that involved 350 teachers and their working spouses (n = 700). The analysis of mediation and moderation among job demands, WFC, FWC, PSC, and depressive symptoms was conducted using SPSS and structural equation modeling AMOS software.
Results
For the teacher’s sample, based on behavioral (β = 0.166, p < 0.05) and strain-based (β = 0.170, p < 0.05) aspects, the hierarchical regression analysis revealed that the PSC moderates the relationship between physical demand and WFC. The results also showed that the relationship between time-based WFC and emotional demand is moderated by PSC (β = 0.103, p < 0.05). Next, the analysis found that PSC moderates the association between cognitive demand and WFC of strain-based (β = 0.179, p < 0.05). For the spouse’s sample, according to the analysis, PSC moderates the relationship between strain-based WFC and physical demand (β = 0.091, p < 0.05). The study also revealed that FWC serves as a mediator in the relationship between WFC and depressive symptoms in both husbands (β = 0.233, p < 0.01) and wives (β = 0.135, p < 0.001).
Conclusions
Overall, this study contributes significant insights to the current literature by examining the impact of PSC on the psychological well-being of individuals and others through the crossover process.

Ann Occup Environ Med 2023;35:e24.   Published online July 19, 2023
DOI: https://doi.org/10.35371/aoem.2023.35.e24
AbstractAbstract AbstractAbstract in Korean PDFSupplementary Material
Background

The construction workers are vulnerable to fatigue due to high physical workload. This study aimed to investigate the relationship between overwork and heart rate in construction workers and propose a scheme to prevent overwork in advance.

Methods

We measured the heart rates of construction workers at a construction site of a residential and commercial complex in Seoul from August to October 2021 and develop an index that monitors overwork in real-time. A total of 66 Korean workers participated in the study, wearing real-time heart rate monitoring equipment. The relative heart rate (RHR) was calculated using the minimum and maximum heart rates, and the maximum acceptable working time (MAWT) was estimated using RHR to calculate the workload. The overwork index (OI) was defined as the cumulative workload evaluated with the MAWT. An appropriate scenario line (PSL) was set as an index that can be compared to the OI to evaluate the degree of overwork in real-time. The excess overwork index (EOI) was evaluated in real-time during work performance using the difference between the OI and the PSL. The EOI value was used to perform receiver operating characteristic (ROC) curve analysis to find the optimal cut-off value for classification of overwork state.

Results

Of the 60 participants analyzed, 28 (46.7%) were classified as the overwork group based on their RHR. ROC curve analysis showed that the EOI was a good predictor of overwork, with an area under the curve of 0.824. The optimal cut-off values ranged from 21.8% to 24.0% depending on the method used to determine the cut-off point.

Conclusion

The EOI showed promising results as a predictive tool to assess overwork in real-time using heart rate monitoring and calculation through MAWT. Further research is needed to assess physical workload accurately and determine cut-off values across industries.

실시간 심박수 측정 장치를 이용한 건설업 근로자 과로 예측 알고리즘
목적
건설업 근로자는 육체적 업무강도가 높아 이에 따른 피로와 그에 따른 사고 및 건강 악영향 우려가 높다. 이 연구에서는 일개 사업장 건설업 근로자를 대상으로 과로와 심박수 사이의 관계를 탐색하고 실시간 심박수 모니터링을 이용하여 과로를 방지하는 방법을 제안하였다.
방법
서울의 일개 건설업 현장에서 근무하는 근로자를 대상으로 2021.08.-2021.10.까지 근무 중 심박수를 측정하였다. 총 66명의 한국인 근로자가 손목시계 형 장치를 이용하여 심박수 측정에 참여하였다. 안정시 심박수와 최대 심박수 추정치를 바탕으로 상대심박수(RHR)를 산출하였고, 이를 바탕으로 피로 없이 근무할 수 있는 최대시간(MAWT)를 계산하여 이를 바탕으로 업무 부담(workload)를 추정하였다. 이를 통해 산출한 누적 업무량으로 과로 지수(Overwork index)를 산출한 후 적정 업무 부담(PSL)과의 차이인 초과 과로 지수(Excess overwork index)를 정의하였다. EOI 값을 이용해 일평균 상대심박수 30%값을 기준으로 정의한 과로군-비과로군을 예측할 수 있는 최적 절단값을 ROC 분석을 통해 산출하였다.
결과
근로자 60명의 심박수 측정값을 분석한 결과 28(46.7%)가 일평균 상대심박수를 기준으로 과로군으로 분류되었다. ROC 분석 결과 EOI값이 과로를 예측하는데 유용함을 확인하였고 AUC값은 0.824였다. 최적 절단 값은 최적화 방법에 따라 21.8%에서 24.0%로 나타났다.
결론
실시간 심박수 모니터링과 MAWT를 이용해 산출한 EOI값은 과로를 예측하는데 유용한 지표임을 확인하였다. 단, 건설업을 비롯하여 다른 육체적 부담이 큰 업종에서 최적 절단값을 찾기 위해서는 추가 연구가 필요하다.

Exploring the impact of age and socioeconomic factors on health-related unemployment using propensity score matching: results from Korea National Health and Nutrition Examination Survey (2015–2017)
Ye-Seo Lee, Dong-Wook Lee, Mo-Yeol Kang
Ann Occup Environ Med 2024;36:e16.   Published online July 1, 2024
DOI: https://doi.org/10.35371/aoem.2024.36.e16
AbstractAbstract AbstractAbstract in Korean PDFSupplementary Material
Background

Previous reports showed that age and socioeconomic factors mediated health-related unemployment. However, those studies had limitations controlling for confounding factors. This study examines age and socioeconomic factors contributing to health-related unemployment using propensity score matching (PSM) to control for various confounding variables.

Methods

Data were obtained from the Korean National Health and Nutrition Examination Survey (KNHANES) from 2015–2017. We applied a 1:1 PSM to align health factors, and examined the association between health-related unemployment and age or socioeconomic factors through conditional logistic regression. The health-related unemployment group was compared with the employment group.

Results

Among the 9,917 participants (5,817 women, 4,100 men), 1,182 (853 women, 329 men) were in the health-related unemployment group. Total 911 pairs (629 women pairs and 282 men pairs) were retained after PSM for health factors. The results of conditional logistic regression showed that older age, low individual and household income levels, low education level, receipt of the Basic Livelihood Security Program benefits and longest-held job characteristics were linked to health-related unemployment, despite having similar health levels.

Conclusions

Older age and low socioeconomic status can increase the risk of health-related unemployment, highlighting the presence of age discrimination and socioeconomic inequality. These findings underscore the importance of proactive management strategies aimed at addressing these disparities, which are crucial for reducing the heightened risk of health-related unemployment.

2015년부터 2017년까지 조사된 국민건강영양조사 자료를 활용하였으며, 건강 관련 실업군을 취업군과 비교하였다. 우리는 1:1 성향점수매칭을 적용하여 두 군 간의 건강관련 요인을 통제하였으며, 조건부 로지스틱 회귀 분석을 통해 건강 관련 실업과 연령 및 사회경제적 요인 간의 관련성을 조사하였다.
결과
9,917명의 참가자(5,817명의 여성, 4,100명의 남성) 가운데 건강 관련 실업군은 1,182명(853명의 여성, 329명의 남성), 취업군은 5,777명(2,894명의 여성, 2,883명의 남성)이었다. 성향점수매칭 후 조건부 로지스틱 회귀의 결과, 고령, 낮은 개인 및 가구 소득, 낮은 교육 수준, 기초생활수급상태, 최장일자리의 성격이 건강 관련 실업과 연관되었다.
결론
고령과 낮은 사회경제적 지위는 건강 관련 실업의 위험을 증가시킬 수 있으며, 이는 연령 차별 및 사회경제적 불평등을 시사한다. 따라서 건강 관련 실업 위험을 완화하기 위해서는 이러한 차별을 해소하기 위한 적극적인 관리 방안이 필요하다.
