Abstract

Shift work does not synchronize with the 24-hour human circadian rhythm, so shift workers experience various problems related to this disruption. This study investigated the relationship between suicidal risk and emotional difficulties such as depression and anxiety in shift workers according to gender. We analyzed data collected from 79,009 health checkup recipients. We checked psychosocial factors for different genders using the Chi-square test and t-tests. To examine the relationship between shift work and suicidal ideation, we estimated an odds ratio after adjustment for age, depression, and insomnia. There was no difference in terms of the risk of suicidal ideation between shift workers and day workers among women (adjusted odds ratio [AOR], 0.957; 95% confidence interval [CI], 0.826–1.109), whereas the risk of suicidal ideation was significantly higher for shift workers than for day workers among men (AOR, 1.157; 95% CI, 1.021–1.310). This study confirmed that associated factors of shift work-related suicidal ideation could act differently by gender. Shift work for women is generally associated with emotional difficulties such as depression and anxiety, whereas maladaptation to shift work may be related to suicidal ideation among men. A gender-specific suicide prevention approaches will be needed for shift workers.

摘要

轮班工作与 24 小时人类昼夜节律不同步，因此轮班工人会遇到与这种中断相关的各种问题。本研究根据性别调查了轮班工人的自杀风险与情绪困难（如抑郁和焦虑）之间的关系。我们分析了从 79,009 名健康检查接受者那里收集的数据。我们使用卡方检验和t检查了不同性别的心理社会因素-测试。为了检验轮班工作与自杀意念之间的关系，我们在调整了年龄、抑郁和失眠后估计了优势比。女性轮班工人和日工的自杀意念风险没有差异（调整优势比 [AOR]，0.957；95% 置信区间 [CI]，0.826-1.109），而自杀意念的风险是在男性中，轮班工人明显高于日工（AOR，1.157；95% CI，1.021–1.310）。该研究证实，与轮班工作相关的自杀意念的相关因素可能因性别而异。女性轮班工作通常与抑郁和焦虑等情绪困难有关，而对轮班工作的适应不良可能与男性的自杀意念有关。
