Objectives A growing number of people depend on flexible employment, characterized by outsider employment status and perceived job insecurity. This study investigated whether there was a synergistic effect of employment status (full-time vs. part-time) and perceived job insecurity on major depressive disorder.
Methods Data were derived from the 2012 Canadian Community Health Survey-Mental Health of 12 640 of Canada’s labor force population, aged 20 to 74. By combining employment status with perceived job insecurity, we formed four employment categories: fulltime secure, full-time insecure, part-time secure, and part-time insecure.
Results Results showed no synergistic health effect between employment status and perceived job insecurity. Regardless of employment status (full-time vs. part-time), insecure employment was significantly associated with a high risk of major depressive disorder. Analysis of the interaction between gender and four flexible employment status showed a gender-contingent effect on this link in only full-time insecure category. Men workers with full-time insecure jobs were more likely to experience major depressive disorders than their women counterparts.
Conclusions This study’s findings imply that perceived job insecurity may be a critical factor for developing major depressive disorder, in both men and women workers.

본 연구는 CCHS-MH (2012) 자료를 이용하여 비정규직과 주관적 고용불안정성이 우울장애에 미치는 시너지 효과를 분석하였다. 연구결과 비정규직 여부와 무관하게, 주관적 고용불안정성은 우울장애와의 연관성이 유의하게 높았다. 특히 정규직 여성보다 정규직 남성에서 주관적 고용불안정성과 우울장애의 연관성이 유의하게 높았다. 이 연구결과는 비정규직 여부보다 주관적 고용불안정성이 주요우울장애에 더 큰 영향요인임을 제시하고 있다.

OBJECTIVE Job insecurity, such as non-standard work, is reported to have an adverse impact on health, regardless of health behaviors. The aim of this study was to examine the relationship between non-standard employment and health in Korea. METHODS: We analyzed a representative weighted sample, which consisted of 2, 112 men and 1, 237 women, aged 15-64, from the 1998 Korea National Health and Nutrition Examination Survey. Non-standard employment included part-time permanent, short time temporary and daily workers. Self-reported health was used as a health indicator. RESULTS: This study indicated that women were more likely to report poorer health than men with standard jobs. Of all employees, 20.3% were female manual workers. After adjusting for potential confounders, such as age, education, equivalent income, marital, social and selfreported economic status and health behavior factors, nonstandard employment was found to be significantly associated with poor health among female manual workers (OR, 1.86; 95% CI, 1.24 to 2.79). No significant association was found in other working groups. CONCLUSIONS: Among female manual workers, nonstandard employees reported significantly poorer health compared with standard workers. This result raises concern as there are increasing numbers of non-standard workers, particularly females.
