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.

Background: Work-Family Conflict means that the demands of work and family roles cannot be met simultaneously, so one cannot concentrate on one's work or family role. This conflict can negatively affect mental health and cause insomnia symptoms. Methods: This study was conducted on 20,442 subjects. Insomnia symptoms were assessed using the Minimal Insomnia Symptom Scale, and other variables were assessed using the questionnaire method. Logistic regression analyses were performed to evaluate the effect of Work-Family Conflict on insomnia symptoms, and subgroup logistic regression analyses were also performed. Results: The number of people with insomnia symptoms was 4,322 (15.1%). Compared with Low Work-Family Conflict, the odds ratios (ORs) for the risk of insomnia symptoms were 1.84 (95% confidence interval: 1.56-2.16) in High work-to-family conflict, 1.16 (1.02-1.32) in High family-to-work conflict, and 3.19 (2.87-3.55) in High Work-Family Conflict. The ORs were higher for men than women in High WFC but higher for women than men in High Work-Family Conflict. Conclusions: The risk of insomnia symptoms was highest in High Work-Family Conflict.

Background: PTSD (Post-traumatic stress disorder, PTSD) had a great impact on health care workers during the COVID-19 (Corona Virus Disease 2019, COVID-19). Better knowledge of the prevalence of PTSD and its risk factors is a major public health problem. This study was conducted to assess the prevalence and important risk factors of PTSD among medical staff during the COVID-19. Methods: The databases were searched for studies published during the COVID-19, and a PRISMA (preferred reporting items for systematic review and meta-analysis) compliant systematic review (PROSPERO-CRD 42021278970) was carried out to identify articles from multiple databases reporting the prevalence of PTSD outcomes among medical staff. Proportion random effect analysis, I² statistic, quality assessment, subgroup analysis, and sensitivity analysis were carried out. Results: A total of 28 cross-sectional studies and the PTSD results of doctors and nurses were summarized from 14 and 27 studies: the prevalences were 31% (95% CI [confidence interval, CI]: 21%-40%) and 38% (95% CI: 30%-45%) in doctors and nurses, respectively. The results also showed seven risks (p < 0.05): long working hours, isolation wards, COVID-19 symptoms, nurses, women, fear of infection, and pre-existing mental illness. Two factors were of borderline significance: higher professional titles and married. Conclusion: Health care workers have a higher prevalence of PTSD during COVID-19. Health departments should provide targeted preventive measures for medical staff away from PTSD.

The circadian system represents a temporal order which is mediated by the mutual coupling of oscillators and by the synchronizing effects of zeitgebers. It is known that well-being of man depends partly on the maintenance of this order, and that repeated or long lasting disturbances to it such as shift work will Cause harmful effects. This study was a quasi-experimental study to test the effect of shift directions for the clinical nurses on the circadian rhythm. Fourteen nurses working at the general units of Y hospital were selected according to the established criteria. Fourteen subjects were assigned to a weekly shift but the directions of shift work were phase delay first and then phase advance or vice versa. Oral temperature, total sleeping time, frequency of sleep-wake cycle, fatigue, mental performance, and physical symptom were measured during these days except holidays. The data collection period was from April 26, 1993 to July 3, 1993. MANOVA and Wilcoxon signed rank test were used for statistical analysis. The results are summarized as follows. 1. Having worked on evening and night shifts in either phase delay or phase advance schedules, temperature rhythms of shift workers were gradually adapted to the new sleep-wake cycles. A complete adaptation to work on the night shift was achieved the sixth day of the night shift in the phase delay schedule compared to the partial adaptation to the work on the night shift in the phase advance schedule. Accordingly, by putting evening shift between day and night shifts, it will be possible for circadian rhythm to adapt easily to the night shift. 2. There were differences in the total sleeping time, frequency of steep-wake cycle, fatigue, and physical symptom except for mental performance between night shift and day, evening shift. This indicates further that shift workers working on the night shift have a hard time adapting to the shift work compared to the other shifts. 3. Evaluating all the acrophases of temperature rhythm either in phase delay or phase ad-vance schedules, it was shown that night to evening shift in the phase ad-vance schedule revealed the smallest phase move. Also phase advance schedule showed poorer adaptation to shift work than phase delay schedule in connection with total sleeping time, frequency of sleep-wake cycle, fatigue, mental performance, and physical symptom. It is suggested, taken together, these findings reflect that phase delay schedule facilitated the degree of adjustment to the shift work compared to the phase advance schedule.

Purposes: Evaluate the level of mental health of administrative workers in medical institutions during the COVID-19 epidemic, and check the relationship. Methodology: It targeted 183 administrative workers at medical institutions located in Jeollabuk-do. The data survey method used a self-filled questionnaire, and the data collection period was 30 days from November 16, 2021 to December 16, 2021. A comparative analysis was conducted to find out the correlation between the subjects' biological factors, environmental factors, lifestyle factors, job related factors and depression, Post Traumatic Stress Disorder, and job stress. Findings: As an influencing factor of depression, it was found that the longer the working period, the higher the depression, and the higher the position, job satisfaction, and the total amount of smoking, the lower the depression. Due to the effect on Post Traumatic Stress Disorder, the higher the total amount of smoking, the higher the Post Traumatic Stress Disorder after effects, and the higher the organizational commitment and job satisfaction, the lower the Post Traumatic Stress Disorder aftereffects. It was found that organizational commitment had the highest influence on Post Traumatic Stress Disorder. As an influencing factor on job stress, it was found that the higher the job related factors was job satisfaction and organizational commitment, the lower the job stress. Practical Implications: Variables such as moderate physical activity, alcohol consumption, total smoking, working period, position, job satisfaction, and organizational commitment were identified as factors influencing depression, Post Traumatic Stress Disorder, and job stress during the COVID-19 pandemic.

Objectives: The objective of the present study was to assess the factors that influence the health of workers, especially nurses, and to propose methods for health management. Methods: A total of 246 nurses were surveyed to ascertain the health status score, Sasang constitution diagnosis, health-related life and job factors, psychosocial stress, and job stress. Depending on their health status score, the subjects were categorized into unhealthy, intermediate, or healthy groups, and each factor was compared with the stress score of the groups. Further, each Sasang constitution factor was also compared with the stress scores. Results: Analysis based on the health status scores indicated that the patients in the intermediate group were older and had longer tenure than those in the unhealthy or healthy groups. The healthy group had higher number of married individuals, and they were subjectively assessed as healthy. Patients in this group were more satisfied with their work than those in the unhealthy group. Analysis of the Sasang constitution showed that a lower percentage of individuals with a Soeumin constitution were married, and most considered themselves to be unhealthy during the subjective health assessment. Conclusions: The findings of this survey revealed that in order to maintain health, efforts should be made to improve the work environment, achieve health confidence, and practice health behavior while considering one's own body, mental state, and constitution.

Objectives: To quantify disability level in salespeople with concurrent low back pain (LBP) and to determine the relative associations between demographic, occupational, psychosocial and clinical factors and back disability. LBP is the most common cause of work-related disability in people under 45 years of age and the most expensive cause of work-related disability, in terms of workers' compensation and medical expenses. Evidence suggests high prevalence of LBP in salespeople. Methods: A cross-sectional survey was conducted in which 184 saleswomen with a current episode of self-reported LBP working in a large up-scale department store filled out a battery of 6 self-administered questionnaires and received a standardised physical examination. Results: Saleswomen with concurrent LBP had low disability levels. Factors significantly associated with disability were pain intensity, measured by a visual analogue scale, in the past week (p < 0.001), physical and mental health status (p < 0.001, p = 0.003, respectively), fear avoidance scores for both work and physical activities (p = 0.031, p = 0.014, respectively), past history of LBP (p = 0.019), and self-reported frequency of pushing or pulling objects placed in high positions during work (p = 0.047). A significant level (45%) of the variance in disability status was explained by these variables. Conclusion: In clinical management of LBP workers who required prolonged standing, such as salespeople, clinicians should look for modifiable risk factors associated with disability. Specific measures need to be taken to prevent disability due to LBP among salespeople.

Background: Healthcare settings have been recognized among the most hazardous places to work. Based on the five categories of occupational hazards that were identified by the ILO and WHO, this study aimed to analyze policy framework relevant to occupational health protection of health workers (HWs) in public health service in China, then discussed how to share the experience of the National Health Service (NHS) England for improvement. Methods: Based on policy learning theories, policy analysis and qualitative interview were used in this study. Results: In the Chinese public health service, at least five laws related to the regulation of occupational health protection for HWs; however, enforcement of relevant laws was separated and multi-centered; the national monitoring system, which targeted to occupational hazards and health outcome for HWs in China, had yet to be developed; the top three priorities were workplace violence, bloodborne pathogens, and musculoskeletal disorders; national strategies included Security Hospital, and Healthy China 2030. In NHS England, three laws were fundamental; several monitoring systems had been set up, including NHS Staff Survey, Commissioning for Quality and Innovation incentive scheme; mental health, musculoskeletal problem, and nutrition disorder and overweight were raised great concern; Health and Safety, and NHS Healthy Workforce Program were critical nationwide strategies. Conclusion: There were several similarities as well as differences between the Chinese public health system and NHS England, which laid foundation of learning by China. Recommendations of improving occupational health policies in China were provided, based on the lessons learned from the NHS England.

목 적 : 본 연구는, 교대근무자에 있어 세 교대근무간의 수면양상과 자율신경계활동성을 비교함으로써, 근무자들은 어떤 근무시에 가장 적합하다고 느끼는지 그리고 교대근무자의 심리적, 신체적 문제점의 특성은 무엇인지를 알아보고자 하였다. 또한 본 연구는 근무자들이 교대근무에 좀 더 효과적으로 적응하는데 도움을 주고자 기획되었다. 방 법 : 3일 정도 연속적으로 한 교대근무를 한 후 1일 휴무, 그 다음에 다른 교대로 넘어가는 빠른 순환주기의 교대근무자 51명이 연구에 참여하였다. 각 대상은 수면일기를 작성하였으며 수면잠복기, 수면기간시간, 수면 중 깨어난 횟수를 세 교대근무간에 비교하였다. Epworth 졸음척도와 시각아날로그척도를 사용하여 졸음을 평가하였으며 기분상태는 기분상태척도로 평가하였다. 심박수변동성과, 스트레스 호르몬(아드레날린, 노르아드레날린) 및 그 대사산물을 측정하여 자율신경계 활동성을 살펴보았다. 심박수변동성에는 저주파영역의 스펙트럼 파워, 고주파영역의 스펙트럼 파워, 저주파영역의 파워와 고주파영역의 파워간의 비가 포함되었다. 결 과 : 수면기간시간은 오후근무시 가장 길었고 수면잠복기는 밤근무시 가장 짧았다. 깨어났을 때의 각성도는 오전근무시 가장 저하되었고 작업 중의 각성도는 밤근무 중 가장 떨어지는 것으로 나타났다. 밤근무시 근무자들은 신체적인 피곤감과 인지기능의 저하를 호소하였다. 심박수변동성의 비교를 통해 오후근무시 부교감신경계가 가장 활성화된다는 것을 알 수 있었으며 아드레날린 및 노르아드레날린 분비도 통계적인 의미는 없었지만 오후근무시 가장 감소하였다. 결 론 : 본 연구결과 오후근무가 교대근무자에게 가장 적합한 것으로 나타났다. 오전근무시에는 빛을 아침에 투여하고 밤근무시에는 근무 중에 빛을 투여하면 교대근무에의 적응이 촉진될 것으로 생각된다.
