Introduction: Preplacement health examination (PHE) is performed when a worker starts a certain work task which is designated as having occupational risks by the Ministry of Employment and Labor (MOEL). All data related to health examination except PHE are reported to the MOEL by the law. This study has been performed to understand the status of PHE at certain workplaces. Methods: PHE data gathered in a university hospital were analyzed and they were followed with results of the special health examination (SHE) in 2019 and 2020. Those who were evaluated as unfit to work as it was, were interviewed directly or indirectly through an occupational health manager to follow up the management status of their recognized health problems. Results: The unfit to work (unFTW) rate of PHE was 2.8%, and was not different according to the size of workplace or having occupational health service. The major cause of unfit to work was the uncontrolled life-style diseases such as hypertension and diabetes. The rate of SHE followed by PHE was 31.1%. It was not different by the unFTW rates, however, they were different according to having a full time in-house occupational health manager. Thirty-one among 71 examinees who were evaluated as unFTW underwent SHE after controlling their health condition and were finally evaluated as fit to work. Nineteen among 31 started to take medicine and eight have been placed in the work without designated risks. Conclusion: PHE can be used for new workers, who may have unknown or uncontrolled life-style diseases, to be asked to manage life-style diseases as well as work-related risks such as shift work. In order to have a better tracking system for work-related risks, the information of PHE should be analyzed together with other data from health examination.

Objectives: Sleep quality is directly related to the health, quality of life and working capacity and is affected by age, gender, exercise, life habits. Gender dissimilarities in sleep quality are acknowledged. However, the gender difference in the quality of sleep in shift workers was not well known. Our aim was to study the less known gender differences in the quality of sleep of shift workers. Methods: 1,008 study subjects aged between 21 and 57 years among these, 637(525 male and 112 female workers) were daytime workers and 371(253 males and 118 female workers) were shift workers. Sleep quality was measured by self-report through the Pittsburg Sleep Quality Index(PSQI) and fatigue was measured by using the Chalder Fatigue Scale(CFS). All data was analyzed using SPSS version 19.0 program. The study was approved by the Institutional Review Board of the Occupational Safety and Health Research Institute. Results: Overall, sleep quality was found to be worse in shift workers than in daytime workers and in female than in male. Fatigue in shift female workers was significantly higher than in daytime female workers and shift male workers. In Spearman correlation analysis results, fatigue were significantly associated with gender, drink habit, regular exercise, working hours and sleep quality. With group male workers as the reference, the odds ratio(OR) for having a CFS was 2.115(${\beta}$ value=0.749, p<0.01), and subjective sleep quality, sleep latency, daytime dysfunction and PSQI were 1.541(${\beta}$ value=0.432, p<0.05), 2.297(${\beta}$ value=0.831, p<0.001), 1.798(${\beta}$ value=0.587, p<0.01) and 2.224(${\beta}$ value=0.799, p<0.01), respectively. Conclusions: Shift work played an important role in lowering the quality of sleep, and the effect was more pronounced in female workers than in male workers. Sleep quality was related to fatigue, especially sleep quality, sleep duration, sleep disturbances and daytime dysfunction were significantly related. Therefore, to improve fatigue and sleep quality of shift worker, it is necessary to improve healthy habits such as regular exercise, smoking cessation, and limited drinking. In particular, it is urgent to develop and implement a regular exercise program to reduce fatigue and improve the quality of sleep in workplace.

Purpose: The purpose of this study was to compare and contrast health promoting behaviors, mental health, and quality of life between shift nurses and non-shift nurses and to evaluate factors influencing their quality of life. Method: Data were collected by questionnaires from 113 non-shift nurses and 265 shift nurses who had been working at one of five hospitals in Incheon for more than one year. Descriptive statistics, ANCOVA, logistic regression, and multiple regression were used in performance of data analysis. Results: For shift nurses' mean total scores for health promoting behaviors and quality of life were significantly lower than those for non-shift nurses'(p<.05). Result of logistic regression analyses indicated that marital status (OR=2.092, 95%CI=1.174-3.729) and quality of life (OR=3.397, 95%CI=1.694-6.812) were significant between shift nurses and non-shift nurses. Non-shift work, low stress, provision of health-welfare programs, high score for health promoting behavior, and good mental health status showed an association with better quality of life (explained 48.3% of variance). Conclusion: Educational, policy, and regulatory approaches are required in order to improve mental health and quality of life for nurses, which may be influenced by their unhealthy behaviors such as irregular dietary patterns, while provision of counseling programs may be helpful to enhancement of nurses' mental health.

이 연구에서는 경찰공무원의 연가 사용 실태를 실증적으로 살펴보았다. 한국경찰은 많은 초과노동에 시달리고 있는 반면, 장시간의 노동으로부터 건강을 보호 회복하고 노동력 재생산 유지와 문화생활 확보 등을 위한 휴가 사용에는 소극적인 편이다. 조사 결과, 대다수의 경찰공무원은 주어진 법정 연가 일수를 절반도 사용하고 있지 않았다. 남자보다는 여자경찰관이, 미혼보다는 기혼경찰관의 연가 사용 일수가 상대적으로 많았으며, 근무환경적 특성별로는 교대 근무자가 비교대 근무를 하는 경찰공무원에 비해 연가 사용 일수가 적은 것으로 나타났다. 소극적인 연가 사용의 원인은 경찰의 업무 과중, 일 중심의 삶, 가정보다는 직장을 우선하는 조직문화 등 다양한 이유들이 결부된 결과일 것이다. 따라서 현실적인 연가 사용이 이루어지기 위해서는 경찰공무원의 업무 과중을 해결해 줄 수 있는 인력충원과 그로 인한 적정한 업무배분이 선행되어져야 할 것이다. 또한 직장과 가정에서의 균형을 중시하는 관리자의 인식과 조직문화의 확산이 시급해 보인다.

This study was conducted to investigate the effect of nutrition education on improving dietary attitudes, food habits and Food Frequency of 32 female shift workers by administering questionnaires. Dietary nutrient consumption data were obtained from the female shift workers by using 1 day 24-hr recall. The results were as follows: Score on 'Concerns about health (p < 0.05)' was significantly higher after-training. Dietary attitude (32.3 vs. 34.9, p < 0.01) and food habits (60.2 vs. 67.1, p < 0.01) were significantly higher after the training. Scores on 'Eating a lot of food that I want to eat is more important than nutrition (p < 0.01)', 'I have a tendency to use instant foods when I am busy (p < 0.01)', 'I am interested in information on nutrition and health (p < 0.01)' were significantly higher after the training. Scores on 'I have three meals a day (p < 0.001)', 'I have breakfast regularly (p < 0.01)', 'I take vegetables other than kimchi at every meal (p < 0.01)', 'I drink milk every day (p < 0.001)', 'I eat fruits every day (p < 0.01)', and 'I apply nutrition knowledge to daily life (p < 0.001)' were significantly higher after the training. Protein (p < 0.05), fiber (p < 0.05), vitamin C (p < 0.01), and calcium (p < 0.001) intakes were significantly higher after the training. These results showed that nutrition education had improved the dietary attitudes, food habits, and nutrient intakes. Therefore, we conclude that providing more systematic and appropriate nutrition education to shift workers during their tenure of office period is likely to improve dietary attitudes, food habits, and nutrient intakes.

Background: In both developed and developing countries, noise is regarded as the most common occupational hazard in various industries. The present study aimed to examine the effect of sound pressure level (SPL) on serum cortisol concentration in three different times during the night shift. Methods: This case-control study was conducted among 75 workers of an industrial and mining firm in 2017. The participants were assigned to one of the three groups (one control and two case groups), with an equal number of workers (25 participants) in each group. Following the ISO 9612 standard, dosimetry was adopted to evaluate equivalent SPL using a TES-1345 dosimeter. The influence of SPL on serum cortisol concentration was measured during the night shift. The serum cortisol concentration was measured using a radioimmunoassay (RIA) test in the laboratory. Repeated measure analysis of variance and linear mixed models were used with ${\alpha}=0.05$. Results: The results indicated a downward trend in the serum cortisol concentration of the three groups during the night shift. Both SPL and exposure time significantly affected cortisol concentration (p < 0.0001, p < 0.0001). Conversely, age and body mass index had no significant influence on cortisol concentration (p = 0.360, p = 0.62). Conclusion: Based on the obtained results, increasing SPL will lead to enhancement of serum cortisol concentration. Given that cortisol concentration varies while workers are exposed to different SPLs, this hormone can be used as a biomarker to study the effect of noise-induced stress.

Background: Although insomnia and constipation are highly prevalent worldwide, studies examining a possible association between them are lacking. We examined the relationship between insomnia and constipation in shift workers who have a high prevalence of insomnia and other diseases. Methods: This study had a multicenter cross-sectional design and conducted using health examination data including self-reported questionnaires. In total, 12,879 and 4,650 shift workers were enrolled in Severance Hospital and Wonju Severance Hospital, respectively, during 2015-2017. Multivariate logistic regression models and subgroup analysis were performed in each center with the same protocol, using a common data model. Results: The mean age of the total population was 44.35 (standard deviation = 8.75); the proportion of males was 56.9%. Female sex, being underweight and non-smoker were strongly associated with an increased risk of constipation symptom (p < 0.001). Pooled odds ratios (ORs) were calculated using ORs of both centers with weights; there was a significant dose-response relationship (sub-threshold 1.76 [95% confidence interval [CI] 1.62-1.91]; moderate 2.28 [95% CI 2.01-2.60]; severe 4.15 [95% CI 3.18-5.41] in the final model, p for trend < 0.001). Subgroup analysis performed by stratifying sex and pooled ORs showed a similar trend to that of the entire group. Conclusion: We observed a strong correlation between insomnia and constipation in this population. Our findings may help in formulating guidelines and policies to improve quality of life in shift workers through the management of sleep quality and proper bowel function. This study is the first to report this relationship among people working in shifts.
