Objectives: The aim of this study is to evaluate the association between shiftwork and skeletal muscle mass index in a single university health check-up. Methods: We used data from 98,227 workers who answered in a special interview on health check-up at a local university hospital from 2014 to 2020. Pearson correlation analysis was conducted for comparing the association between skeletal muscle mass index and demographic and hematological variables in shiftwork and non-shiftwork groups. Mixed linear model analysis after controlling demographic and hematological variables was used to analyze the difference of skeletal muscle mass index between groups at every visit for seven years. Results: In linear regression analysis, the variables most significantly correlated with skeletal muscle index in both groups were shiftwork(p=0.049), BMI(p<0.001), hypertension(p=0.024), platelet(p<0.001), total protein (p<0.001), AST(p=0.028), ALT(p=0.003), ALP(p<0.001), total cholesterol(p=0.002), triglyceride(p=0.019), BUN (p=0.001), creatinine(p<0.001), and uric acid(p=0.002). After the adjustment for demographic and hematologic variables, the skeletal muscle mass index at every visit was decreased both in the shiftwork group and non-shiftwork group. The slope of the shiftwork group was -0.240 and non-shiftwork group -0.149, showing a significant difference (p<0.001). Conclusions: In the shiftwork group, the skeletal muscle mass index showed a tendency to decrease markedly over time compared to the non-shiftwork group. It is presumed that shift workers' skeletal muscle health was adversely affected by changes in the biological clock due to changes in wake-up and sleep patterns, and changes in food intake.

Purpose: The purpose of this study was to identify the factors affecting shiftwork tolerance among nurses and provide basic data, ultimately, in formulating a plan for improving their shiftwork tolerance. Methods: The participants were 317 nurses who were working at three general hospitals in Daejeon and Seoul. Data analyzed t-test, ANOVA, correlation analysis, and regression analysis using SPSS 20.0 program. Results: As for the sub-areas of shiftwork tolerance for the respondents, more than a half of nurses working at shifts suffered from insomnia, felt drowsy, complained of chronic fatigue, and were at the anxious and depressed state. Shiftwork tolerance differed by the daily intake of coffee and exercise. Shiftwork tolerance was significantly positively correlated with sleep-wake habits, hardiness, and flexibility and negatively correlated with a languidity. Regression analysis revealed that shiftwork tolerance was affected by age, sleep-wake habits, languidity, flexibility, and hardiness. Conclusion: To put the results, nurses had shiftwork tolerance affected by sleep-wake habits, languidity, and hardiness. It is therefore necessary to make a scheme for allowing nurses to improve hardiness and flexibility and decrease the languidity with the objective of improving their shiftwork tolerance.

Background: The aim of this study was to investigate the burden experienced by nursing personnel working irregular shifts in Greece and to conduct the first test of a Greek version of the Standard Shiftwork Index (SSI). Methods: A cross-sectional survey was carried out. The SSI was completed by 365 nurses and nursing assistants working shifts, including nights. Results: Female nursing personnel and those suffering from a chronic disease were most affected by working rotating shifts as they had elevated scores on the majority of the SSI scales, such as sleep, chronic fatigue, digestive and cardiovascular problems, general health questionnaire, cognitive and somatic anxiety, shift time satisfaction, engagement and disengagement strategies, languidity, flexibility, and neurotisicm. Nurses with longer working experience and those with family responsibilities also scored higher on some of the SSI scales, such as the sleep, shift time satisfaction, social and domestic disruption, disengagement strategies, morningness, and languidity scales. Conclusion: Shiftwork affects female nurses, those with chronic disease, older age, and domestic responsibilities more severely. Therefore management should take these factors into account when designing work schedules to alleviate the burden caused by shiftwork.

Purpose: The purpose of this study was to compare the working status and Standard Shiftwork Index (SSI) between night shift-fixed nurses and rotating shift nurses. Methods: Participants were 367 nurses working as registered nurses at 7 different medical institutions. The data were collected from August 8, 2016 to September 30, 2016. Results: Night shift fixed nurses were more satisfied with work schedule than rotating shift nurses. Rotating shift nurses reported higher SSI scores, such as chronic fatigue, musculoskeletal problems, than night shift fixed nurses. In SSI's sub-items, rotating shift nurses reported higher scores, such as the amount of sleep, feeling well after sleep, heartburn or stomach-ache and heartbeat irregularities, than night shift fixed nurses. Conclusion: The results indicated that night shift fixed system might be an effective method to improve nurses' work satisfaction. It is necessary to figure out any suitable night shift fixed system based on the characteristics of each nursing organization. The SSI might be an useful tool to measure the nurses' satisfaction in reference to their work shift.

The change in labor consciousness began to draw social attention to work-life balance (WLB). The WLB is one of the major factors affecting the health and safety problems of workers. Although shiftwork adversely affects WLB, safety, and health problems of workers, WLB of shift workers has received little empirical attention. The purpose of this study was to examine whether WLB mediates the relationship between shiftwork and shift worker's safety and health problems, participation in leisure activities moderates WLB, and finally, whether WLB moderated by participation in leisure activities mediates the relationship between shift work and shift worker's safety and health problems. For the study, the data of the 5^th wave of Korean Working Condition Survey(KWCS) conducted by Korea Occupational Safety and Health Agency(KOSHA) of South Korea was used. Conditional process analysis revealed that the relationship between shift work and worker's safety and health problems is mediated by WLB; however, participation in leisure activity showed no moderation effect on WLB. Therefore, the moderated mediation effect has failed to achieve statistical significance. The results indicate that working environment improvement in consideration of the WLB is needed to gain shift worker's long-term safety and health. The implications of this study and suggestions for future research were discussed.

Purpose: This study investigated the dietary behavior of experienced shiftwork nurses and aimed to identify factors related to dietary behavior. Methods: This study was a secondary analysis based on the Shift Work Nurses' Health and Turnover study (2018-2021) among Korean nurses. In total, 247 experienced (>12 months) shiftwork nurses were included in this study. The participants' dietary behavior, depression, level of occupational stress, fatigue, physical activity, and general characteristics were measured. Descriptive statistics, Pearson correlation coefficients, independent t-test, one-way analysis of variance, the Kruskal-Wallis test, and multiple regression analysis were conducted. Results: The dietary behavior score of the participants using the Mini-Dietary Assessment Index was 29.35±5.67. Thirty percent of the participants were depressed, the participants experienced moderate occupational stress, and 74.1% of the participants engaged in an inadequate amount of physical activity. The factors influencing shiftwork nurses' dietary behavior were having child(ren) (β=.16, p=.027), depression (β=-.13, p=.032), level of occupational stress related to occupational climate (β=-.13, p=.035), and an inadequate amount of physical activity (β=-.17, p=.006). These factors explained 10.4% of the variance in experienced shiftwork nurses' dietary behavior scores. Conclusion: Experienced nurses with child(ren) tended to have healthier diets. However, a higher level of occupational stress related to occupational climate, depression, and engaging in an inadequate amount of physical activity were associated with a higher risk of having an unhealthy diet. Therefore, strategies are needed to encourage physical activity and alleviate adverse occupational climate and depression among experienced nurses.

Objective: Shift work including night work is known to be harmful to the health of nurses. This study was conducted in order to systematically review the academic literature on the health effects of working time patterns, including shift work or night work, among Korean nurses and propose a research direction for the future. Methods: We searched online academic databases to find relevant papers in domestic and international journals using the keyword terms 'shift work', 'night work', 'night shift', 'work shift', 'nurse', and 'Korea', and reviewed a total of 36 articles. Results: As a result of this literature review, more than half of the articles were found to investigate the health effects between shiftwork and non-shiftwork nurses. A few studies considered the shift type(n=6), frequency of night shift(n=4), and shiftwork duration(n=3) as working time patterns. These studies focused mainly on mental health(n=18) or sleep(n=15). Conclusions: Based on the review results obtained from this study, it is necessary to assess working time patterns of Korean nurses using a variety of variables including night-work-related factors, and various health outcomes should be examined considering the confounder.
