Long Working Hours

ObjectivesAlthough the effects of long working hours on liver function remain unclear, in South Korea, there is a social perception that long working hours are associated with poor liver function. Thus, long working hours have recently become a major issue. This study aimed to determine the association between long working hours and liver function, as indicated by the alanine transaminase (ALT) levels.DesignCross-sectional study.SettingLarge university hospitals in Seoul and Suwon, South Korea.ParticipantsWorkers in formal employment who underwent a comprehensive health examination at the Kangbuk Samsung Hospital Total Healthcare Centre clinics in Seoul and Suwon, South Korea, between January 2011 and December 2018. Of the 386 488 participants, 212 421 met the inclusion criteria and were included in the analysis.Primary outcome measureALT elevation.ResultsThe participants were predominantly well-educated (86.1%), male (69.3%) and in their 30s (49.6%). In total, 13.4% of the participants presented ALT elevation (>40 IU/L). There was no significant association between working hours and ALT elevation in the general population and in the hepatitis B surface antigen (HBsAg)-negative group. Conversely, in the HBsAg-positive group, working >60 hours per week compared with 35–40 hours per week was significantly associated with ALT elevation. The association was more pronounced in those with ALT levels >80 IU/L (OR 1.94, 95% CI 1.24 to 3.01) than in those with ALT levels >40 IU/L (OR: 1.45, 95% CI 1.20 to 1.75). The p values for trend were <0.05.ConclusionsLong working hours were associated with ALT elevation only in hepatitis B virus carriers and not in the general population. Provided that there is adherence to the legal working hours, there is no need to further restrict working hours for liver health, irrespective of HBsAg status.

ObjectivesThis study aimed to determine the cross-sectional association between long working hours and gastritis diagnosed by endoscopy.DesignCross-sectional study.SettingLarge university hospitals in Seoul and Suwon, South Korea.ParticipantsWorkers in formal employment who underwent a comprehensive health examination at the Kangbuk Samsung Hospital Total Healthcare Centre clinics in Seoul and Suwon, South Korea, between January 2011 and December 2018. Of the 386 488 participants, 168 391 full-time day workers met the inclusion criteria and were included in the analysis.Primary outcome measureEndoscopic gastritis.ResultsThe participants were predominantly college graduates or above (88.9%), male (71.2%) and in their 30s (51.1%), and the median age was 36 (IQR 31–42). Approximately 93.2% of participants had positive endoscopic gastritis, and there was a significant association between working hours and positive findings of endoscopic gastritis. The multivariate fully adjusted prevalence ratio (PR) of endoscopic gastritis for participants working >55 hours per week compared with 35–40 hours per week was 1.011 (95% CI 1.007 to 1.015). Furthermore, endoscopic findings were classified into nine subtypes of gastritis, including superficial gastritis, erosive gastritis, atrophic gastritis, intestinal metaplasia and haemorrhagic gastritis increased with longer working hours (p for trends <0.05). Their PRs for participants working >55 hours per week compared with 35–40 hours per week were 1.019 (95% CI 1.012 to 1.026), 1.025 (95% CI 1.011 to 1.040), 1.017 (95% CI 1.008 to 1.027), 1.066 (95% CI 1.028 to 1.105) and 1.177 (95% CI 1.007 to 1.375), respectively.ConclusionsWorking over 55 hours per week was cross-sectionally associated with positive findings of endoscopic gastritis. The study findings indicated potentially increased risks of superficial gastritis, erosive gastritis, atrophic gastritis, intestinal metaplasia and haemorrhagic gastritis among workers with long working hours (>55 hours per week), supporting the need for further exploration via longitudinal studies.

Abstract Background: This study investigated the association between parental long working hours and the depression of adult children living with them in South Korea. Methods: Data from two years of the Korean National Health and Nutrition Examination Survey (KNHANES) in 2014 and 2016 were analyzed using a cross-sectional study. Study samples included 1334 adult children aged ≥ 19 and 2486 parents (1483 mothers and 1003 fathers). Depression was assessed using the Patient Health Questionnaire-9 (PHQ-9). Logistic regression analyses were performed to determine the association between parental long working hours and their adult children’s depression. Results: Odds ratio (OR) of adult children’s depression for maternal working > 60 hours/week was 4.88 (95% confidential interval (CI): 1.95 – 12.2) when maternal working ≤ 40 hours/week was considered as a reference in the crude model. After considering parental and adult children’s socio-demographic characteristics and occupational characteristics, and parental depression, OR of adult children’s depression for maternal working was found to be 10.2 (95% CI: 2.47 – 42.0). The association between paternal long working hours and adult children’s depression was not statistically significant. Conclusions: Mothers’ long working hours were associated with the greater risk of their adult children’s depression in South Korea. Comprehending aging mothers’ weekly working hours is an important factor when developing strategies for addressing adult children’s depression using family-based interventions.

Machine Operators

A musculoskeletal disorder is highly dependent on the workplace design. The workers whose job requires repetitive tasks, are more prone to this disorder. Textile industry is one of the labor intensive industries and most of its jobs require continuous engagement with the work. Sewing machine operators in this sector due to workplace design are facing high risk of health issues due to focused attention and static posture of the body. Understanding the health issues linked with continuous working hours and static posture need to be addressed. Both Government and non- government organizations need to be better involved in designing interventions targeting these people and protecting them from such health risks.The present study was conducted in Hisar district from Haryana state in which respondents were selected randomly. Total number of respondents were 60 in which 28 were males and 32 were females with objectives to assess work organization and work space design and to find out the occupational health problems and musculoskeletal symptoms among sewing machine operators. The results showed that maximum numbers of the respondents (68.4%) were took break of fixed duration and (53.4%) respondents were work along with others. Majority (43.3%) respondents were the first experience of MSK symptoms from 7 days to 12 months followed by (33.3%) respondents in 2-3 years.

Dental Needs

This study investigates whether workers with long working hours as well as shift workers perceive higher unmet dental care needs, and whether there is a gender difference in the associations. We used the Korea Health Panel (2009, 2011–2014) involving 20,451 person-wave observations from 5567 individuals. Perceived unmet dental care needs was defined when the participants reported that they perceived a need for dental treatment or check-up but had failed to receive dental care services during the past year. Fixed effects logit models were applied to examine how changes in weekly working hours or shift work status were linked to changes in perceived unmet dental needs within each individual. Among participants, 15.9–24.7% reported perceived unmet dental needs and the most common reason was time scarcity. We found that long working hours (>52 h/week) was significantly associated with perceived unmet dental needs due to time scarcity in both men (OR = 1.42, 95% CI 1.13–1.78) and women (OR = 1.35, 95% CI 1.03–1.79) compared workers working 40–52 h per week. Shift work was also a significant risk factor, but only in women (OR = 1.57, 95% CI 1.06–2.32). These findings provide evidence for labor policies to reduce working hours in order to improve access to dental care services.
