Objectives: This study was conducted to find out the prevalence and risk factors of anemia according to shift work. Methods: Data from the Korean National Health and Nutrition Survey (2016-2020) were used. 9,787 workers were divided into shift workers and non-shift workers. The work type between 6AM-6PM was defined as day work, and other work types were defined as shift work. A chi-square test was used to indicate the distribution of risk factors expected to affect shift work in both frequency and percentage. Multiple logistic regression analysis was performed to find out the relationship between anemia prevalence and shift work. Results: As a result of analysis, multiple logistic regression analysis of anemia prevalence and shift work, the OR (95% CI) of male workers on shift work was 2.186 (1.139 to 4.194) and there was a statistically significant difference. Conclusions: In conclusion, anemia in male shift workers should be considered a possibility of health problems. In the future, research based on various data collection should be conducted for research to reveal various causes or diseases of anemia in the future.

Purpose: The purpose of this study was to analyze and clarify the concept of shift work maladaptation syndrome and to facilitate development of interventions for the shift work adaptation. Methods: This study used Walker and Avant's concept analysis process. Results: Shift work maladaptation syndrome can be defined as the following attributes: 1) destruction of the circadian rhythm, 2) existence of a threshold, 3) individual characteristics (year of career, type of personality, and type of coping) 4) somatization, and 5) negative emotional conditions. The antecedents of shift work maladaptation syndrome consist of counterclockwise shift work, irregular shift cycle, night work which is breaking circadian rhythm, and lifestyle changing. The consequences as a result of shift work maladaptation syndrome are deterioration of health (gastrointestinal, neuro-psychic, cardiovascular function), reduction of social relationships, and turnover or resign. Conclusion: The results of this study can be useful as the foundation of shift work adaptation implementation.

Much of the working population in developing countries are engaged in shift work now and the number of shift workers is not expected to decrease in the future mostly because the need for continuity of production is increasing. Therefore, the possible effects of shift work on health are of particular interest, and in fact, there have been many epidemiological studies on shift work since the first world war. However, no studies on health effects of shift work have been reported in Korea, and the existing studies in western world have arrived at quite different conclusions mainly because the conditions of work other than shift work, such as age and selection of workers, work environment, and labor conditions also influence the health of workers. This study was firstly carried out in Korea to investigate the health risks related to shift work with 2,093 female workers randomly selected from three major manufacturing industries in proportion to total number of female workers in those industries. Differences of work conditions other than shift work in this study were adjusted by multivariate analysis. Ma findings obtained from this study are as follows : 1. There were significant differences between shift and day workers in the distribution of age, type of industry, condition of noise and dust, regularity of mealtime, working position, and working duration. Shift workers tended to be younger, to have shorter working duration, to have more irregular mealtime, to work in standing position, and to work under more noisy and dusty environment than day workers. 2. Univariate analysis showed that shift work increased the Todai Health Index (THI) scores of digestive tract, respiratory tract, and mental instability symptom categories. Shift work also increased days of sickness absence and number of industrial accident per 100 workers per month. 3. Multivariate analysis that adjusted the differences of demographic, occupational and non-occupational health-related working conditions showed that digestive tract symptom and mental instability symptom scores were significantly higher in shift workers than those in day workers. Based on these study results, it is concluded that the shift work has significant effects on some psychophysiological conditions of the workers and the effects are also influenced by several other personal and working conditions.

Purpose: This descriptive study was to examine the effect factors on health promotion lifestyle of shift work nurses. Methods: The 418 working nurses who completed questionnaires with consent were analysed. Results: The average level of health promotion lifestyle of shift work nurses was 2.21 and it was significantly lower than 2.36 of fixed work nurses. In shift work nurses, the highest health promotion lifestyle was personal relationship of 2.79 and the lowest was physical activity of 1.58. The young, shorter shift work duration, unmarried and general nurses were evaluated as not-healthy diet. The old, longer shift work duration and married showed less physical activity. Less self-efficacy and more job stress, depression, fatigue showed lower health promotion lifestyle. Conclusion: Self-efficacy on health behavior of shift work nurses was the most effective factor on all areas of health promotion. Therefore, we need to develop a health promotion program including self-efficacy encouragement. We suggest that this program be more effective when more precisely characterized according to age, marital status, shift work duration, job position, and psychological problems such as depression and fatigue.

Purpose: This study aimed to develop and test a structural model for sleep quality in female shift work nurses. The hypothetical model was constructed on the basis of Spielman's 3P model of insomnia and previous research related to the sleep quality of shift nurses. Methods: This cross-sectional study used structural equation modeling and recruited 285 female shift work nurses from four general and university hospitals with over 300 beds located in C and J cities in Gyeongsangnamdo. Data were collected from September 27 to October 20, 2016, and then analyzed using descriptive statistics, Pearson's correlation, and structural equation modeling. The study used SPSS/Win 18.0 and AMOS 18.0 in processing the data. Results: The final model showed good fit to the empirical data: ${\chi}^2/df=2.19$, SRMR=.07, RMSEA=.07, AGFI=.85, TLI=.91, GFI=.93, GFI=.89, NFI=.87. The factors that influenced sleep quality were sleep hygiene (${\beta}=.32$), perceived shift work status (${\beta}=-.16$), stress response (${\beta}=.16$), shift work experience (${\beta}=.15$), perceived health status (${\beta}=-.14)$, and circadian rhythm (${\beta}=-.13$) explaining 36.0% of the variance. Conclusion: The model of sleep quality of the shift work nurses constructed in this study is recommended as a model to understand and predict the sleep quality of shift work nurses. The results suggest that strategies for improving the sleep quality of shift work nurses should focus on sleep hygiene, perceived health status, stress response, circadian rhythm, perceived shift work status, and shift work experience.

Background: A well-designed shift schedule has been reported to have a positive effect on improving health problems associated with shift work. This study aimed to identify compliance with the 17 recommendations on work schedule (WSRs) for shift nurses and related factors. Methods: The descriptive study was conducted with 182 nurses who worked in three shifts for more than 1 year at superior general and general hospitals in three regions. Data were collected with selfadministered questionnaire and 13-week work schedule tables, and analyzed with both person- and cycle-based compliance. Results: Person-based compliance was 11.77 among 17 items in total. However, no one completely complied with WSRs of "no work on weekends" and which showed the lowest cycle-based compliance (22.3%). Compliance with some WSRs was related to hospital type, proportion of nurses in school and having standards on work schedule at institutional level. Conclusion: Compliance with WSRs of shift nurses in Korea is still unsatisfactory, and one day off after night shift and work on weekend are quite common. Hospitals should keep the standards on work schedule, monitor compliance with standards, and try to introduce modified shift systems to improve the current problems.

Purpose: This study aimed to identify the influence of consecutive night-shift work and working time on insomnia among hospital nurses. Methods: A descriptive correlational research designutilizing secondary data analysis was adopted. Data on consecutive night-shift work, working time, and insomnia were collected from 64 hospital nurses using a Fitbit activity tracker and questionnaires, and analyzed using hierarchical logistic regression. Results: Consecutive night-shift work for more than three days had a significant influence on insomnia among hospital nurses. Weekly working hours also accounted significantly for the variance in insomnia, exceeding the influence of consecutive night-shift work. Conclusion: Development and implementation of proper schedules to control consecutive night-shift work and working time is important to alleviate insomnia among hospital nurses.

Objectives: The major objective of this study was to analyze stress response after a change to consecutive day shifts from day and night shifts in a motor assembly factory. Methods: Using a survey conducted by a labor union, we collected data on stress response index(SRI), lifestyle factors, work-family conflict and job stress before and after a shift system change. We analyzed the transition on the SRI among 222 workers. The cut-off point for the SRI was a T-score over 60. Results: The high risk stress response group was 20.3% of the population before the shift system change. After the shift system change it decreased to 11.3%. After the shift system change, social support improved, leisure time became more sufficient, work-family conflict declined, and sleep quality in the night shift week improved. In multivariable linear regression, among workers under 40 years old sleep quality on night shift, leisure time sufficiency, social support and work-family conflict contributed to the improvement of stress response. Among workers over 40, work-family conflict contributed to the improvement of stress response. Conclusions: The change to consecutive day shifts improved stress response and mediated with improved nighttime sleep, decreased work-family conflict, increased leisure time and improved work-family conflict.

Purpose: This study was conducted to assess the effects of shift-work on psychological factors in university hospital's nurses. Method: The subjects were 276 nurses who have worked in a university hospital and the nurses were questioned with self-reported questionnaire forms. We investigated psychological factors(anxiety, depression, stress and self-esteem), nurses' general characteristics and shift-work. The data was analyzed by using SAS for Windows 9.13. Results: The frequency of nurses with anxiety, depression and high stress were 56.5%, 44.9% and 19.6%, respectively. The mean score of self-esteem was 30.03. Stress was higher in cases of having shift-work. Immediately after doing shift-work, nurses had higher depression and stress, and lower self-esteem scores. After controlling confounding variables, psychological factors affected by shift-work was stress. An upward tendency in anxiety, depression and stress were found in cases of doing shift-work for more than 5 years. Conclusions: It is necessary to develope a program for reducing psychological disturbance at the early times of shift-work and to plan adequate shift-work intervals.
