Hepatitis A virus (HAV) is an epidemiologically important virus with a worldwide distribution. It causes acute hepatitis in humans. HAV infection is often subclinical or asymptomatic in children; however, symptomatic acute infections become more common with age. In this study, we investigated the prevalence of anti-HAV among hospital workers in Jeonbuk province. 447 (127 males, 320 females) persons were included in the study from January to June, 2011. Anti-HAV (total and IgM) in the sample serum was measured by VIDAS Hepatitis A (bioMerieux, France), and IgM positive samples were tested in terms of their serum alanine aminotransferase (ALT) levels by a HITACHI 7600-010 automatic analyzer (HITACHI, Japan). The overall prevalence of total anti-HAV was 45.9% (205/447), and rate for males (60.6%) was higher than that for females (40%). According to the age group, the prevalence rates of total anti-HAV were 20% (1/5) in those under 20 years old, 11.3% (18/160) in those 20-29 years, 49.7% (71/143) in those 30-39 years, 86.5% (83/96) in those 40-49 years, 92.9% (26/28) in those 50-59 years, and 40% (6/15) in those over 60 years old. The total prevalence of anti-HAV IgM was 0.8% (4/447), and rate for males (1.6%) was higher than that for females (0.6%). Through this study, we determined the prevalence of anti-HAV among hospital workers in Jeonbuk province. The prevalence of the HAV antibody overall was low in hospital workers under 40 years old and in those over 60 years old. Therefore, an improvement in sanitary conditions and hygiene and vaccinations against HAV in this population are recommended.

Purpose: This study examined the work-related musculoskeletal pain and quality of life of hospital workers. Methods: Self-reported questionnaires were sent to 350 hospital workers at Seoul and Gyeonggi-do, of which 341 were returned. The questionnaire had four items that covered the demographic information, areas of musculoskeletal problems, pain rating scale, and quality of life. The analysis was completed using descriptive statistic, and the differences between pain and demographic variables were identified using a chi-square test. The differences between the type of occupation and quality of life were analyzed by one-way analysis of variance and a Kruskal-Wallis test. Results: The 12-month prevalence of work-related musculoskeletal pain was 86.1% of physical therapists, 86.5% of occupational therapists, 77.1% of dental hygienists, and 75.8% of nurses. A significant difference in the general and work related variables was observed between the subject with a physical burden and type of occupation. The most affected pain sites of the physical therapist included low back, hand and wrist, shoulder, and neck. The occupational therapists included the hand and wrist, shoulder, neck, but the nurses and dental hygienists reported the shoulder, back, hand and wrist. A significant difference in the quality of life was noted between the subjects in physical therapists and dental hygienists and the subjects in the nurses and occupational therapists (p=0.00). Conclusion: These findings show that hospital workers appear to be high risk for work-related musculoskeletal pain, and the quality of life of physical therapists and nurses was higher than that of dental hygienists and occupational therapists.

Objectives: This study aimed to establish a control group based on the big data from National Health Insurance Service. We also presented presented the number of incidences for each cancer, and analyzed the cancer incidence rate among Korean workers. Methods: The cohort definition was separated by 'baseline cohort', 'dynamic cohort', and 'fixed- industry cohort' according to the definition. Cancer incidence was calculated based on the Korean Standard Classification of Disease code. Incidence rate was calculated among the group of all workers and public officials. Based on the study subjects and each cohort definition, the number of observations, incidences, and the incidence rate according to sex and age groups was calculated. The incidence rate was estimated based on the incidence per 100,000 person-year, and 95% confidence intervals calculated according to the Poisson distribution. Results: The result shows that the number of cancer cases in the all-worker group decreases after the age of 55, but the incidence rate tends to increase, which is attributed to the retirement of workers over 55 years old. Despite the specific characteristics of the workers, the trend and figures of cancer incidence revealed in this study are similar to those reported in previous studies of the overall South Korean population. When comparing the incidence rates of all workers and the control group of public officials, the incidence rate of public officials is generally observed to be higher in the age group under the age of 55. On the other hand, for workers aged 60 or older, the incidence rates were 1,065.4 per 100,000 person-year for all workers and 1,023.7 per 100,000 person-year for civil servants. Conclusions: This study analyzed through health insurance data including all workers in Korea, and analyzed the incidence of cancer of workers by sex and age. In addition, further in-depth researches are needed to determine the incidence of cancer by industry.

Background: Shift work increases the risk of chronic diseases, including metabolic diseases. However, studies on the relationship between shift work and renal function are limited. The aim of this study was to investigate the association between shift work and a decreased glomerular filtration rate (GFR). Methods: Data were evaluated for 1,324,930 workers who visited the Korean Medical Institute from January 1, 2016 to December 31, 2020 and underwent a health checkup. Daytime workers were randomly extracted at a ratio of 1:4 after matching for age and sex. In total, 18,190 workers aged over 40 years were included in the analyses; these included 3,638 shift workers and 14,552 daytime workers. Participants were categorized into the shift work group when they underwent a specific health checkup for night shift work or indicated that they were shift workers in the questionnaire. The odds ratio was calculated using a conditional logistic regression to investigate the relevance of shift work for changes in GFR. Results: 35 workers in the shift group and 54 in the daytime group exhibited an estimated GFR (eGFR) value of < 60 mL/min/1.73m² (p < 0.01). The difference in eGFR values between two checkups differed significantly depending on the type of work (p < 0.01); the difference in the shift work group (-9.64 mL/min/1.73 m²) was larger than that in the daytime work group (-7.45 mL/min/1.73 m²). The odds ratio for eGFR reduction to < 60 mL/min/1.73 m² in the shift group versus the daytime group was 4.07 (95% confidence interval: 2.54-6.52), which was statistically significant. Conclusions: The results of this study suggest that eGFR decreases by a significantly larger value in shift workers than in daytime workers; thus, shift work could be a contributing factor for chronic kidney disease (CKD). Further prospective studies are necessary to validate this finding and identify measures to prevent CKD in shift workers.

Background: Although coronavirus disease 2019 is causing a variety of psychological problems for workers, there are few longitudinal studies on changes in workers' mental health by workplace intervention. This study aimed to evaluate the change in the prevalence of depression and anxiety according to the active involvement of the workplace. Methods: This study was conducted on 1,978 workers at a workplace who underwent a health screening from January 2019 to August 2020, and classified depression and anxiety disorders using a self-report questionnaire. After the first pandemic, the company stopped health screening, took paid leave and telecommuting, and conducted interventions such as operating its own screening clinic. To see if this workplace intervention affects workers' mental health, we conducted generalized estimating equations to compare odds ratio (OR). Results: In the pre-intervention group, 384 people (16.86%) had depression, and 507 people (22.26%) had anxiety disorder. Based on the OR before intervention, the OR of depression decreased to 0.76 (0.66-0.87) and the OR of anxiety disorder decreased to 0.73 (0.65-0.82). Conclusions: As a result of this study, it was confirmed that workplace intervention was related to a decrease in depression and anxiety. This study provides basic data to improve workers' mental health according to workplace intervention, and further research is needed according to workplace intervention in the future.

Background: This study aimed to investigate the relationship between work-related communication devices use during work outside of regular working hours and depressive symptoms in wage workers. Methods: Data from 50,538 workers aged 15 years or older who had participated in the 6th Korean Working Condition Survey (KWCS) were used. The final sample was 32,994 wage workers. The questionnaire asked the respondents how often they used communication devices for work during work outside of regular working hours. Depressive symptoms were assessed using WHO-5 Well-Being Index. Multiple logistic regression analysis was used to analyze the association between work-related communication devices use during work outside of regular working hours and depressive symptoms. Results: The rate of depressive symptoms was highest among workers who did not use work-related communication devices during work outside of regular working hours. After adjusting for socio-demographic and work-related factors, the odds ratio of depressive symptoms among workers who used communication devices when working outside of regular working hours was 1.20 (95% CI: 1.09-1.32); the odds ratio of depressive symptoms in the group not using communication devices for free-time work was 1.66 (95% CI: 1.37-2.00), which was higher than that of the reference group, that is, workers who did not work outside of regular working hours, and was statistically significant. Conclusion: Regardless of whether work-related communication devices are used, working outside of regular working hours increases depressive symptoms. The use of work-related communication devices during work outside of regular working hours can reduce the rate of depressive symptoms.
