Employment quality stands as a crucial social determinant impacting workers' health. In this study, we investigate the association between low-quality employment and the emergence of suicidal thoughts and planning.
We analyzed data from 7,797 Korean workers, amounting to 30,945 observations. Low-quality employment was characterized by three primary dimensions: employment insecurity, income inadequacy, and a lack of rights and protection. We employed a generalized estimating equation to probe the link between experiencing low-quality employment and the occurrence of suicidal thought and planning within the subsequent year. Odds ratios (OR) and 95% confidence intervals (CI) were estimated.
The overall incidence rates for suicidal thought and planning were 1.5% and 0.2%, respectively, across the observations. Workers with the lowest employment quality demonstrated higher propensities to develop both suicidal thought (OR: 2.05, 95% CI: 1.37-3.06) and planning (OR: 3.39, 95% CI: 1.08-10.64) at the following year, compared with workers with the highest overall employment quality. Specifically, daily employment exhibited associations with the onset of suicidal thought (OR: 1.64, 95% CI: 1.17-2.31) and suicide planning (OR: 3.49, 95% CI: 1.54-7.92) when compared to permanent employment. Additionally, individuals in the lowest monthly wage quartile displayed a heightened likelihood of developing suicidal thought (OR: 2.09, CI: 1.36-3.23) compared with those in the highest quartile.
Our findings suggest that low-quality employment is associated with the onset of suicidal thought and suicide planning at follow-up. Therefore, employment quality is a critical social determinant of workers' mental health.
就业质量是影响劳动者健康的重要社会决定因素。本研究旨在探讨低质量就业与出现自杀意念和自杀计划之间的关系。
我们分析了 7797 名韩国工人的数据，共计 30945 个观测值。低质量就业的三个主要维度包括就业不稳定、收入不足以及缺乏权利和保护。我们采用广义估计方程来探讨在随后一年中经历低质量就业与出现自杀意念和自杀计划之间的关联。计算了比值比（OR）和 95%置信区间（CI）。
在所有观察中，自杀意念和自杀计划的总发生率分别为 1.5%和 0.2%。就业质量最低的工人出现自杀意念（OR：2.05，95%CI：1.37-3.06）和自杀计划（OR：3.39，95%CI：1.08-10.64）的倾向更高，与就业质量最高的工人相比。具体而言，与固定就业相比，临时工与自杀意念的发生（OR：1.64，95%CI：1.17-2.31）和自杀计划（OR：3.49，95%CI：1.54-7.92）有关。此外，与最高薪 quartile 相比，最低薪 quartile 的个体出现自杀意念的可能性更高（OR：2.09，CI：1.36-3.23）。
本研究结果表明，低质量就业与随访期间自杀意念和自杀计划的发生有关。因此，就业质量是工人心理健康的重要社会决定因素。
