Although a growing body of literature has indicated that unemployment has a positive association with suicide, the dynamic aspects of unstable employment have not yet been considered in suicidology. This study explored the association between employment stability and completed suicide among people aged 25-34 years in 20 OECD (Organization for Economic Cooperation and Development) countries with time-series data (1994-2010). In order to consider the different aspects of unstable employment, we tested the impacts of employment protection legislation indicators as another proxy of job insecurity (employed, but unstable) apart from unemployment rates. Covariates, including economic growth rates, GDP per capita, fertility rates, and divorce rate, were controlled for. The analysis was designed to be gender- and age-specific, where observations with ages of 25-29 were separated from those with ages of 30-34. Random effect models were applied to examine changes over time in suicide rates, and other models were presented to check robustness. The results showed that it is a low level of employment protection, rather than unemployment itself, that was associated with increased suicide rates among all of the studied populations. The magnitude of the effect differed by gender.
尽管越来越多的文献表明失业与自杀存在正相关,但自杀学尚未考虑不稳定就业的动态方面。本研究利用时间序列数据(1994 - 2010年),探讨了20个经合组织(经济合作与发展组织)国家中25至34岁人群的就业稳定性与自杀死亡之间的关联。为了考虑不稳定就业的不同方面,除失业率外,我们还测试了就业保护立法指标作为工作不安全(就业但不稳定)的另一个代理指标的影响。对包括经济增长率、人均国内生产总值、生育率和离婚率在内的协变量进行了控制。分析按性别和年龄进行,将25至29岁的观察对象与30至34岁的观察对象分开。应用随机效应模型来检验自杀率随时间的变化,并给出其他模型以检验稳健性。结果表明,与所有研究人群自杀率上升相关的是就业保护水平低,而非失业本身。影响程度因性别而异。
