一句话总结

本研究使用日本2010年综合生活条件调查的数据，调查了就业状态与失眠相关症状（IRS）之间的关联。在调整混杂因素后，失业和非劳动力状态与更高的IRS几率显著相关，尤其在男性及无精神疾病者中更为明显。

ABSTRACT

This study examined whether employment category was associated with insomnia-related symptoms (IRS). We analyzed the 2010 Comprehensive Survey of Living Conditions in Japan. The anonymous data of 43,865 people ranging from 20-59 yr of age were analyzed. We defined six employment categories: regularly employed, non-regularly employed, self-employed, others, unemployed and not in the labor force. Sex-specific odds ratios (ORs) and 95% confidence intervals (CIs) of IRS were calculated using multivariable logistic regression analysis, adjusted for confounding factors. We further conducted stratified analyses by mental illness, smoking status, and age. For men, the multivariable ORs (95% CI) of IRS for the unemployed and those who were not in the labor force were 2.5 (1.8-3.4) and 2.1 (1.2-3.7). For women, the multivariable ORs (95% CI) for the unemployed was 1.9 (1.5-2.5). After being stratified by mental illness, we found that the associations were not significant in persons with mental illness, and were more evident in persons without mental illness. Smoking and age did not modify the associations. In conclusion, we found a significantly higher OR of IRS for the unemployed, and men who were not in the labor force. These associations were particularly more evident for individuals without mental illness.

研究动机与目标

• 使用全国代表性日本人群数据，检验就业类别与失眠相关症状（IRS）之间的关联。
• 评估该关联是否因性别、精神疾病状况、吸烟状况或年龄而异。
• 确认在调整混杂变量后，就业状态是否为IRS的独立危险因素。
• 探讨精神健康状况、吸烟状况和年龄是否可能产生效应修饰作用。

提出的方法

• 使用多变量逻辑回归计算六种就业类别中IRS的调整后优势比（ORs）和95%置信区间（CIs）。
• 调整了年龄、性别、吸烟状况和精神疾病等潜在混杂因素。
• 按精神疾病、吸烟状况和年龄进行分层分析，以评估效应修饰作用。
• 分析了来自日本2010年综合生活条件调查的43,865名20–59岁个体的匿名调查数据。
• 根据标准化调查标准定义IRS，就业类别包括：正式雇员、非正式雇员、自营业者、其他、失业者和非劳动力。

实验结果

研究问题

• RQ1 在日本，就业状态与失眠相关症状之间是否存在显著关联？
• RQ2 该关联在男性与女性之间有何差异？
• RQ3 精神疾病状况是否调节就业状态与IRS之间的关系？
• RQ4 吸烟状况和年龄是否为就业-IRS关系中的效应修饰因子？

主要发现

• 对于男性，失业者的IRS调整后优势比（OR）为2.5（95% CI: 1.8–3.4），非劳动力者的OR为2.1（95% CI: 1.2–3.7）。
• 对于女性，失业者的IRS调整后OR为1.9（95% CI: 1.5–2.5）。
• 在有精神疾病的人群中，失业与IRS之间的关联不具显著性。
• 该关联在无精神疾病者中更强且更一致。
• 吸烟状况和年龄未显著修饰就业状态与IRS之间的关联。
• 研究结果表明，失业和非劳动力状态是IRS风险的独立相关因素，尤其在男性及无共病精神疾病者中更为显著。
