- 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.

- Background
Recently, irregular working hours have become controversial issues in Korea. The health impact of irregular working hours on the work-related musculoskeletal pain (MSP) is scarcely researched before. We sought to investigate the association between irregular working hours and work-related MSP among South Korean workers.
MethodsThis study used data from the sixth Korean Working Conditions Survey in 2020. The prevalence of work-related MSP was analyzed using the χ2 test. A multiple logistic regression analysis was conducted to assess the association between irregular working hours and work-related MSP. We conducted stratified analysis by gender, weekly working hours, and workers’ control over their working hours. We calculated the adjusted odds ratios (ORs) of work-related MSP for irregular working hours combined with weekly working hours.
ResultsThe OR for work-related MSP was significantly higher in the population with irregular working hours than in the population with regular working hours (OR: 1.43, 95% confidence interval [CI]: 1.29–1.58). Irregular and long (> 52 hours/week) working hours have the highest risk of work-related MSP in both genders (in men, OR: 3.48 [95% CI: 2.53–4.78]; in women, OR: 2.41 [95% CI: 1.46–4.00]).
ConclusionsIrregular working hours were associated with work-related MSP in Korea. The association was magnified with long working hours. Reform of the Korean Labor Standards Act leading to increase irregular working hours may induce adverse health outcome.

Abstract

- Background
The concept of work-life balance (WLB) has become an important issue in workers' health and safety. This study aims to investigate the relationship between WLB and occupational injury and work-related musculoskeletal pain.
MethodThe study included 27,383 workers who participated in the Fifth Korean Working Conditions Survey. Participants were divided into good WLB and poor WLB groups based on their responses to the five question items which comprised two dimensions: work-on-life conflict (items, 1–3) and life-on-work conflict (items 4 and 5). Occupational injury and musculoskeletal pain were also assessed using the question items. The χ2 test and multivariate logistic regression analyses were performed to examine the relationship of WLB to occupational injury and musculoskeletal pain while considering socio-demographic and occupational characteristics and ergonomic and psychological risk factors.
ResultsOf the 27,383 participants, 252 (0.9%) had experienced an occupational injury and 6,408 (23.4%) had musculoskeletal pain. The poor WLB group had higher injury rates for both men (1.7%) and women (0.9%) than the good WLB group (1.1% and 0.4%, respectively). Additionally, the prevalence of musculoskeletal pain was higher for both men and women in the poor WLB group (25.2% and 28.0%, respectively) than for men and women in the good WLB group (18.7% and 23.6%, respectively). In the logistic regression analysis, the adjusted odds ratio of WLB for occupational injury was 1.37 (95% confidence interval [CI]: 1.06–1.78), and that for musculoskeletal pain was 1.14 (95% CI: 1.07–1.21), showing positive associations of WLB with both occupational injury and musculoskeletal pain.
ConclusionsPoor WLB causes an increase in occupational injury and musculoskeletal pain. Therefore, an improvement in WLB may reduce the incidence of occupational injury and musculoskeletal pain among workers. Social and policy-related initiatives are needed to improve workers' WLB to reduce occupational injury and musculoskeletal pain.

Abstract
PDF
- Background
The objective of this study was to compare differences in lifestyle diseases, musculoskeletal pain, psychosocial stress, and self-health awareness according to gender in Korean farmers.
MethodsThe study population comprised 436 farmers residing in rural areas in Korea. A self-administered questionnaire was used to survey demographic characteristics, health-related behaviors, and musculoskeletal pain. The psychosocial well-being index short form (PWI-SF) was used to survey psychosocial stress, and the 12-item short form health survey (SF-12) was used to survey self-health awareness. In addition, a clinical examination was performed for each participant, and lifestyle diseases were identified through a health checkup.
ResultsAmong lifestyle diseases, females showed a significantly higher proportion than males for metabolic syndrome (OR: 4.57 [95% CI, 1.67–12.51]). For musculoskeletal pain, females again showed significantly higher proportion than males for hand pain (OR: 16.79 [95% CI, 3.09–91.30]), and pain in at least one body part (OR: 2.34 [95% CI, 1.16–4.70]). For psychosocial stress, females showed a significantly higher proportion than males for high-risk stress (OR: 3.10 [95% CI, 1.17–8.24]). Among the items in self-health awareness, females showed significantly higher proportion than males for mental component score (MCS) (OR: 3.10 [95% CI, 1.52–6.31]) and total score (OR: 2.34 [95% CI, 1.11–4.90]).
ConclusionsFor all items that showed significant differences, females showed higher proportion than males, which indicates that female farmers tended to have poorer overall health than male farmers. Therefore, specialized programs will have to be developed to improve the health of female farmers.

- Background
Low Back Pain (LBP) is the commonest musculoskeletal disorder and an important occupational hazard among healthcare workers (HCWs) that peaks among Operating Room (OR) staff. This cross-sectional study aimed to assess the prevalence, characteristics, and risk factors of low back pain among operating room (OR) staff in a tertiary healthcare center in Makkah, Saudi Arabia.
MethodsA 39-item self-administered questionnaire was distributed to all available OR staff. Data about personal, sociodemographic, general risk factors OR specific risky activities, and LBP characteristics were obtained. Descriptive, crosstabs, and univariate and multivariate logistic regression tests were employed.
ResultsOut of the 143 distributed questionnaires, 84 % were received. LBP prevalence was 74.2 %. No statistically significant associations were detected between LBP and any of the general risk factors (p >0.05). However, most of the OR risky activities were significantly associated with the occurrence of LBP (p <0.05) e.g. lifting objects above the waist, rotating torso while bearing weight, transferring patients onto bed or chair, pulling a patient up the bed, and repositioning a patient in bed. These significant associations were preserved after adjustment for gender, perceived stress at work, educational level, and receiving education about LBP. Rest and analgesics were reported to be the most common relievers.
ConclusionsLBP is a common health issue among KAMC OR staff. OR risky activities were found to contribute to this problem. We suggest designing educational interventional programs to teach OR staff the best way to prevent this problem.
