ePub Background In today's work scenario, the number of shift workers, including those in night shifts, is increasing. Shift work can adversely affect workers' health in the long run, but studies on the relationship between shift work and depression have shown inconsistent results. This study aimed to determine whether the number of night/shift workers at risk of depression, as predicted by the Patient Health Questionnaire-9 (PHQ-9), is higher than that of day workers.
Methods This study was conducted based on data from the 6th and 7th Korea National Health and Nutrition Examination Survey, 2014, 2016, and 2018. Work schedules were classified into 2 types: day work and night/shift work. This study used the PHQ-9, a self-reported depression screening test, to identify workers at risk of depression. Statistical analysis was performed using SPSS 26.0, and descriptive statistics, χ2 test, and logistic regression analysis were employed.
Results After adjusting for age, educational level, working hours per week, and income, men engaging in night/shift work were at a higher risk of depression (odds ratio [OR]: 1.407, 95% confidence interval [CI]: 0.937–2.113). The same was confirmed for women (OR: 1.564, 95% CI: 1.176–2.081).
Conclusions Our results showed that the OR for those engaged in night/shift work with a PHQ-9 score of 10 or more increased. Considering the large volume of psychiatric history and symptoms in Korea, additional research is needed. Additionally, further discussion on ways to provide realistic help to night/shift workers is warranted.
- 교대근무 여부에 따른 PHQ-9을 이용한 근로자의 우울증 위험 비교: 2014, 2016 및 2018년 국민건강영양조사를 이용하여
목적
현대 사회에서는 야간 근무를 포함하여 다양한 업무를 수행하는 교대 근무자가 증가하고 있다. 교대 근무는 장기적으로 근로자의 건강에 악영향을 미칠 수 있지만 교대 근무와 우울증의 관계에 대한 연구 결과는 일관성이 없는 것으로 나타났다. 본 연구는 PHQ-9로 예측한 우울증에 걸릴 위험이 높은 국내 야간 및 교대 근무 근로자 수가 주간 근로자보다 많은지 여부를 확인하고자 한다.
방법
본 연구는 제 6 차 및 제 7 차 국민 건강 영양 조사 자료 중 2014, 2016년 및 2018년의 자료를 바탕으로 진행되었다. 근무 일정은 주간 근무와 야간 및 교대근무로 구분 하였다. 이 연구는 우울증에 걸릴 위험이 있는 근로자를 결정하기 위해 자가 보고 우울증 선별 검사 인 PHQ-9를 사용하였다. SPSS 23.0을 이용하여 통계 분석을 수행하였고 통계적 방법으로는 기술 통계, 카이 제곱 분석, 로지스틱 회귀 분석을 사용 하였다.
결과
연령, 교육 수준, 주당 근무 시간 및 수입으로 보정 후 분석하였을 때, 야간 및 교대 근무 근로자에서 우울증 위험군에 해당하는 경우가 유의하게 더 높았으며(odds ratio [OR] = 1.407 (95% confidence interval [CI]: 0.937–2.113)), 이는 여성에서도 마찬가지로 나타났다(odds ratio [OR] = 1.564 (95% confidence interval [CI]: 1.176–2.081)).
결론
본 연구를 통해 야간 및 교대근무 근로자에서 PHQ-9 점수가 10점 이상인 우울증 위험군에 해당하는 경우가 유의하게 높음을 확인할 수 있었다. 현재 한국의 정신 병력과 증상의 유병률을 고려할 때 야간 근로자에게 현실적인 도움을 제공 할 수 있는 방법에 대한 추가 논의와 함께 추가 연구가 필요하다. -

Background Although recent studies have investigated the influence of vitamin D on sleep patterns, there is a lack of research on the relationship between vitamin D and sleep patterns in Korean workers. This study focused on the relationship between serum vitamin D levels and sleep in fixed day indoor field workers in the electronics manufacturing industry in Korea.
Methods The 1472 subjects who were included in this study were selected from fixed day workers in the electronics manufacturing industry who had received a worker’s special health examination at a hospital in Changwon, South Gyeongsang Province between January 2015 and December 2015. Nighttime workers and those who showed symptoms of depression were excluded from this study. The sociodemographic and lifestyle variables of the participants were investigated, including age, sex, marital status, level of education, body mass index, smoking habits, alcohol consumption habits, and regular exercise. Work-related factors were evaluated, such as employee tenure and occupational stress. Serum 25-hydroxyvitamin D was measured as an indicator of vitamin D levels, and quality of sleep was evaluated using the Pittsburgh Sleep Quality Index (PSQI) translated into Korean.
Results The subjects had a mean serum vitamin D level of 13.70 ± 5.93 ng/mL. Vitamin D deficiency, defined as a serum vitamin D level of <10 ng/mL, was found in 24.8% of males and significantly more frequently in females (47.6%). Poor sleep quality was reported by 19.8% of participants with serum vitamin D levels ≥10 ng/mL and by 21.7% of those with serum vitamin D levels <10 ng/mL, which was a significant difference (
P = .007). Multiple logistic regression analysis adjusting for significant variables found that poor sleep quality was more likely in those with vitamin D deficiency than those with higher serum vitamin D levels (odds ratio = 1.36; 95% CI, 1.01–1.82). A comparison of serum vitamin D levels and PSQI components showed that the mean scores for subjective sleep quality, sleep latency, and sleep duration were significantly higher in the vitamin D-deficient participants, indicating that the vitamin D-deficient participants had poorer sleep quality.Conclusions This study investigated serum vitamin D levels in fixed day indoor field workers in the manufacturing industry in Korea and analyzed the relationship of vitamin D deficiency with sleep quality. A significant correlation was found between serum vitamin D deficiency and poor sleep quality. Based on the results of this study, sleep disorder management for workers can be improved by providing regular examinations checking their serum vitamin D levels and supplying vitamin D to workers with serum vitamin D deficiency to enhance their quality of sleep.
