Effect of job satisfaction on depression after adjusting for satisfaction with other life domains: SeongCheol Yang, Ji Hoon Kim, Minju Jung, Hwan-Cheol Kim, Jong-Han Leem, Shin-Goo Park; Ann Occup Environ Med 2024;36:e8. Published online March 28, 2024; DOI: https://doi.org/10.35371/aoem.2024.36.e8

Abstract Abstract in Korean PDF PubReader ePub: Background
Studies on the association between job satisfaction and depression have often been reported. However, no study has examined how job satisfaction impacts depression while considering satisfaction with other aspects of life. In this study, we evaluated the effect of job satisfaction on depression after adjusting for satisfaction with other domains of life.
Methods
We used data from the 16th wave of the Korean Welfare Panel Study. A total of 3568 current employees without depression who completed a survey were included. Depression was measured using the abbreviated version of the CES-D scale. Various types of satisfaction, including job satisfaction, were measured using single-item questions and a 5-point Likert scale. The association between job satisfaction and depression after considering satisfaction with other life domains was analyzed using a multiple logistic regression model.
Results
Crude models showed a significant association between job satisfaction and depression in males (odds ratio [OR]: 7.90; 95% confidence interval [CI]: 4.11–15.23) and females (OR: 7.12; 95% CI: 4.40–11.50). When adjusted for sociodemographic factors, health-related factors, and work-related factors, the association remained significant in males (OR: 6.20; 95% CI: 3.10–12.41) and females (OR: 6.28; 95% confidence interval (CI): 3.79–10.40). However, when satisfaction with other life domains was included, the association remained significant only in females (OR: 3.55; 95% CI: 1.93–6.50).
Conclusions
This study shows an association between job satisfaction and depression in Korean employees. However, when satisfaction with other life domains was considered, this association remained significant only in women. Regular screening of job satisfaction should be considered as a means of preventing and managing depression among female employees.; 삶의 다른 영역의 만족도들을 보정한 후 일 만족도가 우울에 미치는 영향
목적
과거의 많은 연구들에서 일 만족도와 우울 사이에 연관성이 있음이 밝혀졌다. 그러나, 삶의 다른 영역의 만족도들까지 고려하여 일 만족도가 우울에 미치는 영향을 조사한 연구는 현재까지 없었다. 이번 연구는 삶의 다른 영역의 만족도들을 보정하여 일 만족도와 우울 사이의 연관성을 평가하였다.
방법
본 연구는 한국복지패널 (Korean Welfare Panel Study)의 16차 조사자료를 활용하였다. 우울증을 진단받은 적이 없고 설문을 완료한 총 3568명의 임금 근로자가 선정되었다. 우울은 축약형 CES-D를 이용하여 평가했으며, 직업 만족도를 포함한 여러 만족도들은 5점 리커트 척도로 구성된 단일 문항으로 평가했다. 삶의 다른 영역의 만족도들에 대해 보정하여 직업 만족도와 우울간의 연관성을 분석하기 위해 다중 로지스틱 회귀분석을 수행하였다.
결과
보정되지 않은 모형에서 우울에 대한 오즈비는 남성의 경우 일 만족 그룹에 비해 일 불만족 그룹에서 7.90 (95% CI: 4.11-15.23), 여성의 경우 7.12 (95% CI: 4.40-11.50)였다. 사회인구학적 요인, 건강 요인, 직업 관련 요인에 대해 보정했을 때도 남성에서 오즈비 6.20 (95% CI: 3.10-12.41), 여성에서 오즈비 6.28 (95% CI: 3.79-10.40)이었다. 그러나, 추가로 삶의 다른 영역의 만족도들에 대해 보정하여 분석했을 때는, 여성에서만 일 만족도와 우울 간에 유의미한 연관성이 나타났다 (OR=3.55, 95% CI: 1.93-6.50).
결론
연구결과에 따르면, 삶의 다른 영역의 만족도들을 고려하여 분석했을 때 일 만족도와 우울 사이의 연관성은 여성에서만 유의미했다. 우울을 예방하기 위한 한 방법으로, 직장에서 여성 근로자들에 대해 정기적으로 직업 만족도를 확인하고 관리해야 할 것이다.

Occupational stress changes and new-onset depression among male Korean manufacturing workers: Jiho Kim, Hwan-Cheol Kim, Minsun Kim, Seong-Cheol Yang, Shin-Goo Park, Jong-Han Leem, Dong-Wook Lee; Ann Occup Environ Med 2023;35:e33. Published online August 17, 2023; DOI: https://doi.org/10.35371/aoem.2023.35.e33

Abstract Abstract in Korean PDF PubReader ePub: Background
Studies on the association between occupational stress and depression have been frequently reported. However, the cross-sectional designs of studies limited insight into causal associations. In this study, we investigated the longitudinal association between occupational stress and new-onset depression among employees in a single manufacturing plant.
Methods
The annual health checkup data of employees at a manufacturing plant in Korea were collected. A total of 1,837 male employees without depression who completed a health checkup during two consecutive years were included. Occupational stress was measured using a short form of the Korea Occupational Stress Scale (KOSS-SF), and depression was assessed using a Patient Health Questionnaire-2. The association between occupational stress change over the two years and newly developed depression was investigated using two logistic regression models.
Results
Across all sub-factors of KOSS-SF, employees who reported increased occupational stress had a higher risk of new-onset depression. Newly developed depression was significantly associated with job demand (odds ratio [OR]: 4.34; 95% confidence interval [CI]: 2.37–7.96), job insecurity (OR: 3.21; 95% CI: 1.89–5.48), occupational climate (OR: 3.18; 95% CI: 1.91–5.31), lack of reward (OR: 2.28; 95% CI: 1.26–4.12), interpersonal conflict (OR: 2.14; 95% CI: 1.18–3.86), insufficient job control (OR: 1.93; 95% CI: 1.05–3.56), and the organizational system (OR: 1.84; 95% CI: 1.01–3.36).
Conclusions
For every sub-factor of the KOSS-SF, occupational stress increase and persistent high stress were associated with the risk of developing new-onset depression. Among the seven sub-factors, job demand had the most significant effect. Our results show that occupational stress should be managed to promote employee mental healthcare.; 한국 남성 제조업 근로자의 직무 스트레스 변화와 우울증 발생의 관계
목적
직무 스트레스와 우울증의 연관성에 대한 연구는 지속적으로 보고되고 있다. 그러나 국내 연구는 부족한 실정이며 주로 단면적 분석 설계에 국한되고 있다. 이 연구에서 우리는 단일 제조업 공장의 근로자들에서 직무 스트레스와 새롭게 발병하는 우울증 사이의 종단적 연관성을 조사하였다.
방법
국내 한 제조업 공장 근로자들의 연간 건강검진 자료를 수집하였다. 2년 연속 건강검진을 완료한 이들 중 우울증이 없는 남성은 총 1837명이었다. 직무 스트레스는 Korea Occupational Stress Scale KOSS Short Form (KOSS-SF)으로 측정하였고, 우울증은 Patient Health Questionnaire-2(PHQ-2)로 평가하였다. 1년 간의 직무 스트레스 변화와 새로 발생한 우울증과의 연관성을 로지스틱 회귀 모델을 사용하여 분석했다.
결과
KOSS-SF의 모든 하위 영역에서 직무 스트레스가 증가했다고 보고한 근로자는 새로운 우울증 발병 위험이 더 높았다. 새로 발생한 우울증의 위험은 각각 직무 요구[교차비(OR)=4.34, 95% 신뢰 구간(CI)= 2.37–7.96], 직무 불안정(OR=3.21, 95%CI=1.89–5.48), 직장문화(OR=3.18, 95%CI=1.91–5.31), 보상 부적절(OR=2.28, 95%CI=1.26–4.12), 관계 갈등(OR=2.14, 95%CI=1.18–3.86), 직무 자율성 결여(OR=1.93, 95%CI=1.05–3.56) 및 조직체계(OR=1.84, 95%CI=1.01–3.36) 순이었다.
결론
KOSS-SF의 모든 하위 영역에서 직무 스트레스 증가와 높은 스트레스 상태의 지속은 새로운 우울증 발병 위험과 관련이 있었다. 7가지 하위 영역 중 직무 요구가 가장 큰 영향을 미쳤다. 우리의 결과는 근로자 정신 건강을 증진하기 위해 직무 스트레스를 관리해야 함을 시사한다

The relationship between fatigue and sickness absence from work: Minsun Kim, Jiho Kim, SeongCheol Yang, Dong-Wook Lee, Shin-Goo Park, Jong-Han Leem, Hwan-Cheol Kim; Ann Occup Environ Med 2023;35:e32. Published online August 10, 2023; DOI: https://doi.org/10.35371/aoem.2023.35.e32

Abstract Abstract in Korean PDF PubReader ePub: Background
Although many studies have been conducted on worker fatigue and sickness absence, the association between fatigue and sickness absence is unclear in Korean workers. This study was conducted to investigate the effect of worker fatigue on future sickness absence.
Methods
The study was conducted on workers who received medical check-ups at a university hospital for two consecutive years (2014–2015). During check-ups in the first year, the Fatigue Severity Scale (FSS) was used to assess fatigue levels, and during check-ups in the second year, sickness absence was surveyed to determine whether they had been absent from work due to physical or mental illness during previous 12 months. The χ² test was used to analyze relationships between sociodemographic and occupational characteristics, fatigue levels, and sickness absence. Odds ratios (ORs) were calculated by logistic regression analysis controlled for confounding factors.
Results
A total of 12,250 workers were included in the study, and 396 (3.2%) workers experienced more than one day of sickness absence during the study period. Adjusted ORs for sickness absence were 3.35 (95% confidence interval [CI]: 2.64–4.28) in the moderate-fatigue group and 6.87 (95% CI: 4.93–9.57) in the high-fatigue group versus the low-fatigue group. For men in the moderate- and high-fatigue groups, adjusted ORs for sickness absence were 3.40 (95% CI: 2.58–4.48) and 8.94 (95% CI: 6.12–13.07), and for women in the moderate- and high-fatigue groups, adjusted ORs for sickness absence were 2.93 (95% CI: 1.68–5.10) and 3.71 (95% CI: 1.84–7.49), respectively.
Conclusions
Worker fatigue is associated with sickness absence during the following 12 months, and this association appears to be stronger for men than women. These results support the notion that sickness absence can be reduced by evaluating and managing work-related fatigue.; 근로자의 피로와 질병 결근의 연관성
목적
근로자의 피로와 질병 결근에 관한 많은 연구가 이루어졌으나, 한국 근로자의 피로와 질병 결근의 연관성은 불분명합니다. 본 연구는 근로자의 피로가 미래의 질병 결근에 미치는 영향을 조사하기 위해 수행되었습니다.
방법
본 연구는 2년 연속(2014년-2015년) 대학병원에서 건강검진을 받은 근로자들을 대상으로 실시되었습니다. 첫번째 2014년 건강검진에서는 피로 심각도 척도를 이용하여 피로도를 평가했고, 다음해인 2015년 건강검진에서는 같은 근로자를 대상으로 지난 12개월 간 신체적 질환 또는 정신적 질환으로 인한 결근한 적이 있는지를 조사했습니다. χ2 분석으로 사회인구학적 특성과 직업적 특성, 피로도와 질병 결근의 연관성을 분석하였습니다. 오즈비는 교란 요인들을 통제 후 로지스틱 회귀 분석을 통해 측정되었습니다.
결과
연구 대상에는 총 12,250명의 근로자가 포함되었으며, 12개월 동안 396명(3.2%)의 근로자가 하루 이상의 질병 결근을 하였습니다. 질병 결근에 대한 조정된 오즈비는 낮은 피로 그룹에 비해 중간 피로 그룹에서 3.35 (95% CI: 2.64-4.28), 고피로 그룹에서 6.87 (95% CI: 4.93-9.57)였습니다. 남성의 질병 결근에 대한 조정된 오즈비는 중간 피로 그룹에서 3.40 (95% CI: 2.58-4.48), 고피로 그룹에서 8.94 (95% CI: 6.12-13.07)였으며, 여성의 질병 결근에 대한 조정된 오즈비는 중간 피로 그룹에서 2.93 (95% CI: 1.68-5.10), 고피로 그룹에서 3.71 (95% CI: 1.84-7.49)이었습니다.
결론
근로자의 피로는 이후 12개월 동안의 질병 결근과 관련이 있으며, 이 연관성은 여성보다 남성에게 더 강한 것으로 보입니다. 이러한 결과는 업무 관련 피로를 평가하고 관리함으로써 질병 결근을 줄일 수 있다는 개념을 뒷받침합니다.

Impacts of presenteeism on work-related injury absence and disease absence: Youna Won, Hwan-Cheol Kim, Jiho Kim, Minsun Kim, Seong-Cheol Yang, Shin-Goo Park, Jong-Han Leem; Ann Occup Environ Med 2022;34:e25. Published online September 23, 2022; DOI: https://doi.org/10.35371/aoem.2022.34.e25

Abstract Abstract in Korean PDF PubReader ePub

Background

Many studies have been conducted on presenteeism and absenteeism, but the relationship between presenteeism and absenteeism is unclear. This study was undertaken to investigate the effect of presenteeism on future absenteeism.

Methods

This study was conducted on non-white collar workers that underwent general health examinations in 2014 and 2015. We asked subjects to fill out a questionnaire about their experiences of presenteeism for the past one year in 2014. In 2015, it was checked whether the same subjects had any experience of absence from work due to injury or disease during the past year. The χ² test was used to analyze relationships between sociodemographic and occupational characteristics, presenteeism, and absence. Odds ratios (ORs) were calculated by logistic regression analysis controlled for confounding factors.

Results

A total of 12,572 workers were included in the study. For workers who experienced presenteeism, the OR for injury absence was 2.705 (95% confidence interval [CI]: 2.044–3.581), and the OR for disease absence was 4.906 (95% CI: 3.996–6.024) after adjusting for sociodemographic and occupational confounding factors. For men that experienced presenteeism, the OR for injury absence was 3.035 (95% CI: 2.258–4.081), and the OR for disease absence was 5.508 (95% CI: 4.340–6.989). For women that experienced presenteeism, the OR for injury absence was 1.322 (95% CI: 0.577–3.028), which was not significant, and the OR for disease absence was 3.629 (95% CI: 2.405–5.475).

Conclusions

This study suggests that presenteeism can influence future absenteeism. The effect of presenteeism may depend on cause of absence. Men who experienced presenteeism showed greater effects on injury and disease absence than women. For women, experience of presenteeism had a significant effect on disease absence but not on injury absence.

작업관련 손상결근과 질병결근에 대한 프리젠티즘의 영향
목적
프리젠티즘과 결근에 대한 많은 연구가 있어왔지만 그 상관관계는 여전히 불분명하다. 본 연구는 프리젠티즘이 미래의 결근에 미치는 영향을 조사하기 위해 수행되었다.
방법
본 연구는 2014년과 2015년에 한 대학병원에서 일반건강검진을 받은 비사무직근로자를 대상으로 실시하였다. 2014년 설문지 작성을 통해 지난 1년간의 프리젠티즘 여부를 조사하였다. 동일 근로자를 대상으로 2015년에는 1년간의 손상 및 질병 결근 여부를 확인하였다. 카이제곱 검정을 통해 사회인구통계학적, 직업적 특성과 프리젠티즘, 결근 간의 관계를 분석하였다. 교란 요인을 통제하여 로지스틱 회귀분석을 수행해 오즈비(OR)를 계산했다.
결과
총 12,572명의 근로자가 연구에 포함되었다. 사회인구학적 및 직업적 교란 요인을 조정한 후 프리젠티즘을 경험한 근로자에서 손상결근의 오즈비는 2.705(95% CI: 2.044-3.581), 질병결근의 오즈비는 4.906(95% CI: 3.996-6.024)이었다. 성별에 따라 나눈 결과, 프리젠티즘을 경험한 남성에서 손상결근의 오즈비는 3.035(95% CI: 2.258~4.081), 질병결근의 오즈비는 5.508(95% CI: 4.340~6.989)이었다. 여성의 경우는 프리젠티즘을 경험한 후 손상결근 오즈비가 1.322(95% CI: 0.577-3.028)로 유의미하지 않았고, 질병결근 오즈비는 3.629(95% CI: 2.405-5.475)로 나타났다.
결론
본 연구는 프리젠티즘이 미래 결근의 요인이 될 수 있음을 시사한다. 결근의 원인에 따라서 프리젠티즘의 영향은 달라질 수 있다. 남성과 여성을 분류했을 때, 프리젠티즘을 경험한 남성은 여성보다 손상과 질병 결근 모두에서 더 큰 영향을 보였고, 여성은 질병결근과 달리 손상결근에서는 이러한 영향이 나타나지 않았다.

Background

The aim of this study is to investigate the relationship between fatigue and occupational injury.

Methods

This study was conducted at a university hospital in 2014 and 2015. In 2014, the fatigue severity scale (FSS) was used to evaluate workers' fatigue levels. Later, when the same workers were examined in 2015, a questionnaire survey was conducted to determine whether they had experienced absences or treatment for work-related accidents. The χ² test was used to analyse the relationship between demographic characteristics, fatigue levels, and occupational injuries. After controlling for confounders, a logistic regression analysis was performed to calculate the odds ratios (ORs).

Results

In 2014, 19,218 workers were screened during health examination and their fatigue level were evaluated using FSS questionnaires. in 2015, workers' occupational injury was evaluated. In result, men in the moderate- and high-fatigue groups, after adjusting for age, smoking and drinking habits, chronic diseases, and occupational factors such as size of company industrial classification and type of work (shift or non-shift), adjusted ORs for hospital treatment due to occupational injury were 1.76 (95% confidence interval [CI]: 1.39–2.24) and 2.61 (95% CI:1.68–4.06), respectively. Among men in the medium- and high-fatigue groups, the adjusted ORs for absence due to occupational injury were 2.06 (95% CI: 1.52–2.80) and 3.65 (95% CI: 2.20–6.05), respectively. No significant association was observed between fatigue and occupational injury in women.

Conclusions

Male workers with high fatigue levels have a higher risk of experiencing work injuries. This study suggests that active intervention be considered to prevent injuries in workers with high scores on workplace fatigue evaluation scales.

Association between nicotine dependency with occupational injury in Korean men: Sung Wook Jang, Hwan-Cheol Kim, Ji Ho Kim, Min Sun Kim, Youna Won, Hyeonwoo Ju, Hyung Doo Kim, Go Choi, Shin-Goo Park, Jong-Han Leem; Ann Occup Environ Med 2021;33:e14. Published online May 4, 2021; DOI: https://doi.org/10.35371/aoem.2021.33.e14

Abstract PDF Supplementary Material PubReader ePub

Background

The relationship between smoking status or second-hand smoking and occupational injuries has been the subject of considerable study, but few have studied the relationship between nicotine dependence and occupational injuries. The objective of this study was to investigate the relationship between nicotine dependence and occupational injury among employees at a range of Korean companies.

Methods

Initially, the personal and occupational characteristics and nicotine dependences of workers were measured, and 12 months later a survey was used to determine whether subjects had experienced any occupational injury. This study was conducted in several workplaces on 6,893 male workers in manufacturing and service industries that received health screening at Inha University Hospital in Incheon.

Results

The adjusted odds ratios (ORs) of occupational injury in the low, moderate, and high nicotine dependence groups were 1.38 (95% confidence interval [CI]: 1.04–1.84), 1.52 (95% CI: 1.10–2.10), and 1.71 (95% CI: 0.92–3.19), respectively. For smokers only, adjusted ORs tended to increase linearly (p for trend < 0.05). When only smokers were included, analysis of continuous FTND (Fagerstrom Test of Nicotine Dependence) scores showed that adjusted OR increased by 1.10 (95% CI: 1.03–1.19) per FTND point. After stratifying the data by working type and working hours per week, the non-shift work group maintained this relationship (OR: 1.13, 95% CI: 1.04–1.24) and OR was higher in the group that works more than 60 hours per week with FTND score as a continuous variable (OR: 1.24, 95% CI: 1.07–1.44).

Conclusions

The study shows nicotine dependency might affect occupational injury. From a short-term perspective, addressing worker's nicotine dependence by giving an adequate break time or smoking area might reduce work-related injuries.

Abstract PDF PubReader ePub

Background

Most of the studies that have examined the association between the sub-factors of occupational stress and depressive symptoms have used cross-sectional data. However, our study has longitudinally measured the occupational stress and depressive symptoms of Korean workers of a semiconductor manufacturing company across six years to intending to investigate the associations between the sub-factors of occupational stress and depressive symptoms using longitudinal data.

Methods

Data collected from the workers of a semiconductor manufacturing company. Out of 1,013 recruited workers, 405 (40.0%) completed the survey questionnaires at 3 and 6-year follow-ups. Occupational stress was measured using a shorter version of the Korean Occupational Stress Scale (KOSS), whereas depressive symptoms were assessed using the Korean version of the Center for Epidemiological Studies-Depressive Symptoms Scale (CES-D). The data of male and female participants independently analyzed. Longitudinal associations were analyzed using panel data analysis with fixed effects.

Results

In panel data analysis with fixed effects, job insecurity (B = 0.048, p-value = 0.004) was associated with depressive symptoms among male workers. In female workers, inadequate social support (B = 0.080, p-value < 0.001), job insecurity (B = 0.039, p-value = 0.004), lack of reward (B = 0.059, p-value = 0.004) and discomfort in occupational climate (B = 0.074, p-value < 0.001) were associated with depressive symptoms among female workers.

Conclusions

Temporal changes in the sub-factors of occupational stress were associated with changes in depressive symptoms within the same period. There was a gender difference in occupational stress sub-factors related to depressive symptoms.

The relationship between precarious employment and subjective well-being in Korean wage workers through the Cantril ladder Scale: Go Choi, Shin-Goo Park, Youna Won, Hyeonwoo Ju, Sung Wook Jang, Hyung Doo Kim, Hyun-Suk Jang, Hwan-Cheol Kim, Jong-Han Leem; Ann Occup Environ Med 2020;32:e11. Published online April 17, 2020; DOI: https://doi.org/10.35371/aoem.2020.32.e11

Abstract PDF PubReader ePub

Background

The global labor market is moving towards increasing job instability. Relatively few studies have examined the relationship between precarious employment and subjective well-being using quantitative scales. We evaluated the association between wage workers' employment status and their subjective well-being through the Cantril ladder scale using Korean Welfare Panel Survey data (KOWEPS).

Methods

This study used KOWEPS data. A total of 4,423 wage workers were divided into permanently employed workers, temporarily employed workers and daily employed workers. The relationship between precarious employment and subjective well-being was analyzed by multiple linear regression adjusted for potential confounding factors.

Results

The more unstable the employment status, the lower the subjective well-being, which can be expressed by the Cantril ladder scale. The mean score of both temporarily employed and daily employed workers were statistically significantly lower (B = −0.454, p < 0.001; B = −0.994, p < 0.001, respectively) than permanently employed workers. This appeared to be the same when occupational and sociodemographic factors were adjusted (B = −0.153, p = 0.002 for temporarily employed, B = −0.610, p < 0.001 for daily employed).

Conclusions

The more unstable the employment status, the lower the subjective well-being score according to the Cantril ladder scale.

Relationship between occupational sunlight exposure and the incidence of renal cancer: Hyun-Suk Jang, Jong-Han Leem, Seong Soo Jeon, Shin-Goo Park, Sangyoon Lee, Yangwon Kang, Go Choi, Hyung Doo Kim, Hyeonwoo Ju, Sung Wook Jang, Youna Won, Hwan-Cheol Kim; Ann Occup Environ Med 2019;31:e32. Published online November 7, 2019; DOI: https://doi.org/10.35371/aoem.2019.31.e32

Abstract PDF PubReader ePub: Background
The risk factors for renal cancer include smoking, obesity, hypertension, and exposure to trichloroethylene. Recent studies have shown that low sunlight exposure increases the risk of developing a range of cancers, including renal cancer. Given that most of the daytime is spent at work, a lack of occupational sunlight exposure can be a risk factor for renal cancer. Therefore, this study examined the relationship between occupational sunlight exposure and the incidence of renal cancer.
Methods
This was a university hospital-based case-control study on renal cancer. Of the 706 newly diagnosed patients with renal cell carcinoma (RCC), 633 cases were selected; 73 who had no occupational history were excluded. In addition, 633 controls were selected from the general population after 1:1 matching with respect to sex, age (within 5 years), and residential area (constituency-level). Information on sunlight exposure by the occupational group was referred to data from France. To estimate the association between occupational sunlight exposure and the RCC risk, the odds ratios (ORs) were calculated using conditional logistic regression analysis.
Results
Sunlight exposure was divided into quartiles and the risk of RCC was analyzed. The adjusted OR of RCC (OR: 0.664, 95% confidence interval: 0.449–0.983) was significantly lower for the Q4 group than Q1 group but the Q2 and Q3 groups did not show significant results. The risk of RCC tended to decrease with increasing exposure to sunlight (p for trend < 0.028).
Conclusions
Higher occupational sunlight exposure reduces the risk of RCC.

Satisfaction with life and the risk of occupational injury: Sung-Min Park, Hwan-Cheol Kim, Shin-Goo Park, Hyun-Suk Jang, Go Choi, Jong-Han Leem; Ann Occup Environ Med 2018;30:49. Published online August 2, 2018; DOI: https://doi.org/10.1186/s40557-018-0260-x

Abstract PDF PubReader ePub

Background

Occupational injuries increase burden on society as well as personal health. Low satisfaction with life may not only increases the risk of occupational injuries directly, but also influences other factors that increase the risk of occupational injury. Along with previous studies on the risk of occupational injury, we sought to explore the relationship between satisfaction with life and occupational injury.

Methods

The study participants were 6234workers health screened at a university hospital in Incheon. Information on occupational injury and satisfaction with life scale (SWLS) was obtained in a self-report format. Participants were allocated to one of four SWLS groups; the dissatisfied group, the slightly dissatisfied group, the slightly satisfied group, and the satisfied group. The analysis was performed using the chi-square test primarily and by logistic regression adjusted for potential confounders.

Results

In men, the un-adjusted and adjusted odds ratios (ORs) of low satisfaction with life (SWLS< 20) were 1.98(CI1.55–2.53) and 1.81(CI 1.41–2.32), respectively. When the SWLS were divided into four groups, the adjusted ORs of the slightly satisfied (20–25), slightly dissatisfied(15–19), and dissatisfied(≤14) groups were 1.21, 1.72, and 2.70, respectively. That is ORs tended to increase linearly with decreasing SWLS score (p for trend < 0.001). In women, this relation was of borderline significance at best.

When subjects were dichotomized based on SWLS scores, for males, the cured and adjusted RRs of occupational injury in the low satisfaction with life group were1.91 (95% CI: 1.50–2.42) and 1.66 (95% CI: 1.30–2.13), and for females, the adjusted-RR was marginally significant (1.67; 95% CI: 0.93–2.99).

When subjects were divided into four groups by SWLS scores, adjusted RRs tended to increase linearly with decreasing SWLS score for males (slightly satisfied: 1.18, 95% CI: 0.77–1.82; slightly dissatisfied: 1.65, 95% CI: 1.08–2.52; dissatisfied: 2.22, 95% CI: 1.44–3.42; p for trend < 0.001) and for females (slightly satisfied: 1.17, 95% CI: 0.42–3.30; slightly dissatisfied: 1.56, 95% CI: 0.56–4.36; dissatisfied: 2.38, 95% CI: 0.84–6.74; p for trend = 0.040).

Conclusions

This study suggests that the risk of occupational injury was higher in workers not satisfied with life, and indicates attention to satisfaction with life may promote the health of workers.

Association between second-hand smoke and psychological well-being amongst non-smoking wageworkers in Republic of Korea: Seong-Jin Kim, Dirga Kumar Lamichhane, Shin-Goo Park, Bum-Joon Lee, So-Hyun Moon, Sung-Min Park, Hyun-Suk Jang, Hwan-Cheol Kim; Ann Occup Environ Med 2016;28:49. Published online September 20, 2016; DOI: https://doi.org/10.1186/s40557-016-0130-3

Abstract PDF PubReader ePub

Background

Worldwide, exposure to second-hand smoke (SHS) has been responsible for more than 0.6 million deaths and 10.9 million disability-adjusted life years (DALYS) lost in never smokers in 2004. The world health organization (WHO) reported smoking-related death of 58,000 per year in South Korea. There is recent emerging evidence of the associations of SHS exposure with anxiety or depression and poor mental health. Although exposure to second-hand smoke (SHS) has been associated with various physical health conditions and mental health, we are unaware of any studies examining its association with psychological well-being as mental factor. This study aimed to investigate the association between self-reported exposure to SHS and well-being among non-smoking wageworkers.

Methods

The Third Korean Working Conditions Survey (KWCS, 2011) was conducted on a representative sample of economically active population aged 15 years or over, who were either employees or self-employed at the time of interview. In this study, after removing inconsistent data, 19,879 non-smoking wageworkers among 60,054 workers were participated. Psychological well-being was measured through the WHO-Five Well-Being Index (1998 version). Univariate and multiple logistic regression models were used to examine the association of SHS exposure with psychological well-being.

Results

The unadjusted OR of poor psychological well-being (OR: 1.594, 95 % CI: 1.421-1.787) was significantly higher for SHS exposure group compared to non-exposure group. Multiple logistic regression analysis results indicated that these relationships were still significant after adjusting for potential confounders (adjusted OR: 1.330, 95 % CI: 1.178-1.502).

Conclusions

Exposure to SHS was associated with poor well-being measured by the WHO-5 well-being index, indicating the importance of reducing SHS exposure at the workplace for psychological well-being amongst non-smoking wageworkers.

Abstract PDF PubReader ePub

Objectives

Working conditions can exert influence on the physical, mental, and even social health of workers. Well-being is an appropriate index for the evaluation of a person’s overall health. This paper investigated the association between various working conditions and worker’s well-being.

Methods

Data from 10,019 interviews were collected from the second wave of the Korean Working Conditions Survey (2010) conducted by the Korea Occupational Safety and Health Agency between June and October 2010. The data from 5,995 employed workers were examined in this study. Well-being was measured through the WHO Five Well-Being Index (1998 version). Sociodemographic and working conditions were analyzed. Adjusted odds ratios for well-being were calculated with adjusted sociodemographic factors, working condition factors, or both.

Results

Workers’ well-being was significantly higher when they were satisfied with their working conditions (OR = 1.656, 95% CI = 1.454–1.885), when their actual working hours were the same as their anticipated working hours (OR = 1.366, 95% CI: 1.120–1.666) or exceeding less than 10 hours (OR = 1.245, 95% CI: 1.004-1.543), and when their employment was stable (OR = 1.269, 95% CI: 1.098–1.467).

Conclusions

This study supports the association between working condition factors and well-being in workers.

Abstract PDF PubReader ePub

Objectives

The purpose of the present study was to identify the association between presenteeism and long working hours, shiftwork, and occupational stress using representative national survey data on Korean workers.

Methods

We analyzed data from the second Korean Working Conditions Survey (KWCS), which was conducted in 2010, in which a total of 6,220 wage workers were analyzed. The study population included the economically active population aged above 15 years, and living in the Republic of Korea. We used the chi-squared test and multivariate logistic regression to test the statistical association between presenteeism and working hours, shiftwork, and occupational stress.

Results

Approximately 19% of the workers experienced presenteeism during the previous 12 months. Women had higher rates of presenteeism than men. We found a statistically significant dose–response relationship between working hours and presenteeism. Shift workers had a slightly higher rate of presenteeism than non-shift workers, but the difference was not statistically significant. Occupational stress, such as high job demand, lack of rewards, and inadequate social support, had a significant association with presenteeism.

Conclusions

The present study suggests that long working hours and occupational stress are significantly related to presenteeism.

Objectives

Sleep is essential for human beings to live and work properly. This study was conducted to investigate the relationship between occupational exposures to workplace risk factors and sleep disturbance in Korean workers.

Methods

The data were drawn from the second Korean Working Conditions Survey (KWCS); a total of 7,112 paid workers were analyzed. The independent variables were occupational exposures such as physical, chemical, biological, and psychosocial risk factor in the workplace, and psychosocial risk factor was divided into five categories (job demand, job control, social support, job insecurity, lack of reward). We estimated the relationship between various occupational exposures and sleep disturbance using multivariate logistic regression analysis.

Results

The results showed that people who exposed to physical, chemical, biological, and psychosocial (high job demand, inadequate social support, lack of reward) risk factors were more likely to increase the risk of sleep disturbance. Furthermore, after adjusting for general and occupational characteristics, we found significant positive associations between exposures to physical (odds ratios [OR] 1.47, 95% confidence interval [CI] 1.05-2.07) and psychosocial (high job demand (OR 2.93, 95% CI 2.16-3.98), inadequate social support (OR 1.57, 95% CI 1.14-2.15), lack of reward (OR 1.45, 95% CI 1.08-1.96)) risk factors and sleep disturbance.

Conclusion

These results suggest that occupational exposures to physical and psychosocial workplace risk factors are significantly related to sleep disturbance.

Objectives

Korea is well known for its long work hours amongst employees. Because workers of the manufacturing industry are constantly exposed to extended work hours, this study was based on how long work hours affect their emotional well-being.

Methods

The analysis was done using the secondary Korean Working Condition Survey (KWCS). Long work hours were defined to be more than 48 hours, and they were subcategorized into units of 52 hours and 60 hours. Based on the WHO (five) well-being index, emotional state was subdivided into three groups - reference group, low-mood group, and possible depression group- where 28 points and 50 points were division points, and two groups were compared at a time. Association between long work hours and emotional state was analyzed using binary and multinomial logistic regression analysis.

Results

Working for extended working hours in the manufacturing industry showed a statistically significant increase (t test p < 0.001) in trend among the possible depression group when compared to the reference group and the low-mood group. When demographical characteristics, health behaviors, socioeconomic state, and work-related characteristics were fixed as controlled variables, as work hours increased the odds ratio of the possible depression group increased compared to the reference group, and especially the odds ratio was 2.73 times increased for work hours between 48–52 and 4.09 times increased for 60 hours or more and both were statistically significant. In comparing the low-mood group and possible depression group, as work hours increased the odds ratio increased to 1.73, 2.39, and 4.16 times, and all work hours from working 48–52 hours, 53–60 hours, and 60 hours or more were statistically significant. Multinomial logistic regression analysis also showed that among the reference group and possible group, the possible depression group was statistically significant as odds ratio increased to 2.94 times in working 53–60 hours, and 4.35 times in 60 hours or more.

Conclusions

Long work hours have an adverse effect on emotional well-being. A more diversified research towards variables that affect long work hours and emotional well-being and how they interact with each other and their relationship to overall health is imperative.
