Mental health problems among workers have become an issue in Japan. The working environment for civil servants is becoming excessively stressful, and there is a need to prevent the onset of depression. In addition to stress at the workplace and at home, social capital has been reported as a factor associated with depression. This study examined whether workplace social capital reduces the association between depression and work-related stress or depression and home-related stress.
A total of 3015 Japanese civil servants (1867 men and 1148 women) from Toyama Prefecture were included in this study. Data on depression and workplace social capital, work status, work stress, work-life balance, and physical health were collected.
The odds ratio for depression was higher for both men and women with low workplace social capital. For those with low workplace social capital, the adjusted odds ratio for depression was 2.93 (95% confidence interval [CI], 2.16-3.98) for men and 2.46 (95% CI, 1.74-3.49) for women. After adjusting for workplace social capital, the associations between depression and low job position, low job support, and moderate family-to-work conflict declined in men and were no longer significant. For women, the strength of the association between depression and unmarried status along with moderate control at work decreased and also lost significance. When the ORs for depression were stratified by high and low workplace social capital and compared with the ORs before stratification, the ORs for depression of long working hours and work-to-family conflict increased for both men and women in the low workplace social capital group.
Workplace social capital mitigated the effect of workplace and family stress leading to depression in both men and women.
劳动者的心理健康问题在日本已成为一个议题。公务员的工作环境压力过大，有必要预防抑郁症的发生。除了工作场所和家庭的压力外，社会资本也被报道为与抑郁症相关的一个因素。本研究调查了工作场所社会资本是否能减少抑郁症与工作相关压力或抑郁症与家庭相关压力之间的关联。
本研究纳入了来自富山县的3015名日本公务员（1867名男性和1148名女性）。收集了关于抑郁症、工作场所社会资本、工作状况、工作压力、工作与生活平衡以及身体健康的数据。
工作场所社会资本低的男性和女性患抑郁症的比值比均较高。对于工作场所社会资本低的人，男性患抑郁症的调整后比值比为2.93（95%置信区间[CI]，2.16 - 3.98），女性为2.46（95%CI，1.74 - 3.49）。在对工作场所社会资本进行调整后，男性中抑郁症与低职位、低工作支持以及中度家庭与工作冲突之间的关联减弱且不再显著。对于女性，抑郁症与未婚状态以及工作中适度控制之间的关联强度降低且也失去了显著性。当按工作场所社会资本的高低对抑郁症的比值比进行分层，并与分层前的比值比进行比较时，工作场所社会资本低的组中，男性和女性因长时间工作和工作与家庭冲突导致抑郁症的比值比均增加。
工作场所社会资本减轻了工作场所和家庭压力对男性和女性导致抑郁症的影响。
