Precarious employment is one of the most important indicators of social disadvantage and is associated with poor mental health. This study aimed to investigate the association of precarious employment with depressive mood and suicidal ideation in adult wage workers, and the possible mediating or moderating effect of socioeconomic factors in the association between precarious work and mental health status.
Data from the Fifth Korea National Health and Nutrition Examination Survey (KNHANES V) conducted between 2010 and 2012 were analyzed. Among the 24,173 participants, 6266 adult wage workers (3206 precarious and 3060 non-precarious workers) aged ≥19 years were included. Socioeconomic and health-related characteristics as well as depressive mood and suicidal ideation were investigated.
Precarious employment was significantly associated with depressive mood in the logistic regression analyses adjusting for all potential confounding factors as covariates. The socioeconomic variables including age, gender, education level, marital status, household income, and occupation type were significantly related with depressive mood and suicidal ideation in adult wage workers. We also found that gender and household income had possible moderating effects on the association between precarious employment and suicidal ideation. Precarious work was associated with suicidal ideation only for male workers and worker with low or middle-lower income levels.
Our study is based on a cross-sectional design, thus, we could not elucidate the causal relationship between the variables.
Our study suggested that precarious employment plays a pivotal role in the mental health status of adult wage workers.
不稳定就业是社会劣势的最重要指标之一，且与心理健康状况不佳有关。本研究旨在调查成年工薪族中不稳定就业与抑郁情绪及自杀意念之间的关联，以及社会经济因素在不稳定工作与心理健康状况之间关联中可能起到的中介或调节作用。
对2010年至2012年进行的第五次韩国国家健康与营养检查调查（KNHANES V）的数据进行分析。在24173名参与者中，纳入了6266名年龄≥19岁的成年工薪族（3206名不稳定就业者和3060名稳定就业者）。调查了社会经济和健康相关特征以及抑郁情绪和自杀意念。
在将所有潜在混杂因素作为协变量进行调整的逻辑回归分析中，不稳定就业与抑郁情绪显著相关。包括年龄、性别、教育水平、婚姻状况、家庭收入和职业类型在内的社会经济变量与成年工薪族的抑郁情绪和自杀意念显著相关。我们还发现，性别和家庭收入对不稳定就业与自杀意念之间的关联可能具有调节作用。不稳定工作仅与男性工人以及低收入或中低收入水平的工人的自杀意念相关。
我们的研究基于横断面设计，因此，我们无法阐明变量之间的因果关系。
我们的研究表明，不稳定就业在成年工薪族的心理健康状况中起着关键作用。
