背景：抑郁症对工人的生产力和健康有很大的影响。最近，日本社会和政府报告说，加班是导致工人抑郁和自杀的主要原因之一。然而，只有少数研究调查了加班时间与心理健康状况之间的关系，结论各不相同。此外，先前的研究结果在抑郁症与生活方式因素（包括饮酒和吸烟）之间的关系方面并不一致。需要进一步的研究来阐明日本工人中可能的风险因素与抑郁症之间的关系。方法：我们进行了病例对照和队列研究。研究对象是四家日本公司的办公室职员。抑郁症的诊断是由两位精神科医生根据DSM-IV-TR标准进行独立临床访谈做出的。结果：加班与抑郁发作无显著相关性。酒精摄入的频率与抑郁症的发生有显著关系。我们还发现年龄越小和抑郁发作之间有显著的关系。身体质量指数和身体疾病（包括糖尿病）与抑郁发作无显著关联。局限性：数据为自我报告，纳入的女工人数较少。结论：仅靠减少工作时间并不能有效预防员工抑郁。还需要采取其他对策，包括减少酒精摄入量和工作压力。还需要考虑年轻员工。(C) 2010 Elsevier B.V.版权所有
Background: Depression influences a worker's productivity and health substantially. Recently, the Japanese society and government reported that working overtime is one of the primary causes of depression and suicide in workers. However, only a few studies have investigated the relation between overtime hours and mental health status, and conclusions vary. In addition, prior findings are inconsistent in terms of the relation between depression and lifestyle factors, including alcohol intake and smoking. Additional studies are required to clarify the relation between possible risk factors and depression in Japanese workers.Methods: We performed a case-control and a cohort study. Subjects were office workers in four Japanese companies. Diagnosis of depression was made by two psychiatrists who conducted independent clinical interviews using DSM-IV-TR criteria.Results: There was no significant association between working overtime and the onset of depression. The frequency of alcohol intake was significantly related to the onset of depression. We also found a significant relation between younger age and depression onset. Body mass index and physical illness, including diabetes mellitus, had no significant association with depression onset. Limitations: Data were self-reported and the number of included female workers was small.Conclusions: Reducing working hours alone is unlikely to be effective in preventing workers' depression. Additional countermeasures are needed, including a reduction in alcohol intake and work stress. Considerations for younger workers are also needed. (C) 2010 Elsevier B.V. All rights reserved.
