BACKGROUND
Previous studies on the association between shift or night work and weight change have been focused on finding the risk of weight gain caused by shift or night work. In this study, we aimed to reveal the risk of weight gain and weight loss associated with night work by using a nationwide representative data.
METHODS
This study was performed on 1605 full-time wage workers between the age of 20 and 69 based on the fifth Korea National Health and Nutrition Examination Survey (KNHANES 2010-2012). The association between night work and involuntary weight change in the previous year was divided into the categories of weight gain and weight loss and studied with modifications in socio-demographic variables, health behavior-related variables, and occupational characteristic variables.
RESULTS
The participants working in night work accounted for 10.6 % of total study participants (male; 11.9 %, female 7.4 %). Workers who worked more than 48 hours per week on average accounted for 41.6 % of the total study participants (male; 46.3 %, female 29.1 %). Odds ratio (OR) of weight loss associated with night work in male workers was 0.34 (95 % confidence interval (CI) 0.16-0.76) after controlling for several related factors. OR of weight loss associated with night work in female workers with long working hours was 1.95 (95 % CI 0.47-80.86) and that of weight gain was 2.83 (95 % CI 0.12-69.83) after adjusting associated factors.
CONCLUSIONS
In this cross-sectional study with national representative sample, night work may lower the risk of weight loss in male workers and induce weight change (weight loss or weight gain) in female workers with long working hours. Therefore, future studies with cohort study design for night workers are needed to reveal the mechanisms and health effects of weight change associated with night work and establish proper management solutions with health and labor policies for Korean night workers.
背景
以往关于轮班或夜班工作与体重变化之间关联的研究主要集中于探寻轮班或夜班工作导致体重增加的风险。在本研究中，我们旨在利用全国代表性数据揭示与夜班工作相关的体重增加和体重减轻风险。
方法
本研究基于第五次韩国国民健康与营养检查调查（KNHANES 2010 - 2012），对1605名年龄在20至69岁之间的全职受薪工人进行。将夜班工作与上一年非自愿体重变化之间的关联分为体重增加和体重减轻两类，并在社会人口统计学变量、健康行为相关变量和职业特征变量进行调整后进行研究。
结果
从事夜班工作的参与者占研究总参与者的10.6%（男性为11.9%，女性为7.4%）。平均每周工作超过48小时的工人占研究总参与者的41.6%（男性为46.3%，女性为29.1%）。在控制了几个相关因素后，男性工人中与夜班工作相关的体重减轻的比值比（OR）为0.34（95%置信区间（CI）0.16 - 0.76）。在调整相关因素后，长时间工作的女性工人中与夜班工作相关的体重减轻的OR为1.95（95% CI 0.47 - 80.86），体重增加的OR为2.83（95% CI 0.12 - 69.83）。
结论
在这项具有全国代表性样本的横断面研究中，夜班工作可能会降低男性工人体重减轻的风险，并导致长时间工作的女性工人出现体重变化（体重减轻或体重增加）。因此，需要对夜班工人进行队列研究设计的未来研究，以揭示与夜班工作相关的体重变化的机制和健康影响，并通过针对韩国夜班工人的健康和劳动政策制定适当的管理解决方案。
