To investigate the effects of job security on new development of depressive episode, suicide ideation, and decline in self-rated health.
Data from the Korea Welfare Panel Study from 2012 to 2015 were analysed. A total of 2912 waged workers self-assessed their depressive episode, suicide ideation, and health annually by answering the questionnaire. Participants were divided into three groups according to the level of job security: high, intermediate and low. To evaluate the influence of job security, we performed survival analysis after stratification by gender with adjustment for covariates. The result was further stratified by whether the respondent was the head of household.
After adjusting for covariates, men in low job security group showed significantly higher hazard ratios (HRs) for depression (HR 1.27, 95% CI 1.01-1.60), suicide ideation (HR 3.25, 95% CI 1.72-6.16), and decline in self-rated health (HR 1.73, 95% CI 1.16-2.59). Women showed significantly higher HR of depression in the intermediate (HR 1.37, 95% CI 1.01-1.87) and low (HR 1.50, 95% CI 1.12-1.99) job security group. Male head of household with low job security showed significantly higher HR of depression, suicide ideation, and decline in self-rated health. Non-head-of-household women with intermediate and low job security showed higher risk of depression than those with high job security.
We found that perceived job insecurity is associated with the new development of depressive episode, suicide ideation, and decline in self-rated health.
探讨工作保障对抑郁发作、自杀意念和自我健康评估下降新发病的影响。
对 2012 年至 2015 年韩国福利面板研究的数据进行了分析。共有 2912 名受薪工人通过回答问卷每年自我评估抑郁发作、自杀意念和健康状况。根据工作保障水平，参与者被分为三组：高、中、低。为了评估工作保障的影响，我们在按性别分层并调整协变量后进行了生存分析。结果进一步按是否为家庭户主进行分层。
调整协变量后，低工作保障组的男性抑郁（HR 1.27，95%CI 1.01-1.60）、自杀意念（HR 3.25，95%CI 1.72-6.16）和自我健康评估下降（HR 1.73，95%CI 1.16-2.59）的风险比（HR）显著较高。女性在中等（HR 1.37，95%CI 1.01-1.87）和低（HR 1.50，95%CI 1.12-1.99）工作保障组中抑郁的 HR 显著较高。低工作保障的男性户主抑郁、自杀意念和自我健康评估下降的 HR 显著较高。中等和低工作保障的非户主女性出现抑郁的风险高于高工作保障的女性。
我们发现，感知到的工作不安全感与抑郁发作、自杀意念和自我健康评估下降的新发病有关。
