While a number of work-related events have been proposed as risk factors for depression, a majority of studies have focused only on a few events in a single study. Therefore, we conducted a web-based longitudinal study to comprehensively investigate the impact of various work-related events on depressive symptoms. Ten thousand Japanese workers representing the Japanese working population were recruited online and questioned on their experiences of 36 work-related events in the past year. Their depressive symptoms were also assessed based on the Center for Epidemiologic Studies Depression Scale. Two years later, 3,098 participants responded to a follow-up study. By excluding 1,030 participants who were classified as being depressed in the baseline survey, data of 2,068 participants were analyzed. Odds ratios (OR) were calculated using multivariate logistic regression to assess the effect of work-related events on depressive symptoms. Sixteen events were found to be risk factors and were sorted into four types as follows: experience of an accident or disaster (OR: 4.78–7.67), excessive responsibility (OR: 3.01–3.62), drastic change in workstyle or workload (OR: 2.38–3.08), and interpersonal conflict (OR: 2.41–11.16). The current results, including magnitude relationship of ORs, should be utilized for promoting psychosocially healthy work environment.

虽然已经提出了许多与工作有关的事件作为抑郁症的危险因素，但在一项研究中，大多数研究仅关注少数事件。因此，我们进行了基于网络的纵向研究，以全面调查各种与工作有关的事件对抑郁症状的影响。网上招聘了代表日本劳动人口的一万名日本工人，并询问了他们在过去一年中与36项与工作有关的活动的经历。还根据流行病学研究中心抑郁量表对他们的抑郁症状进行了评估。两年后，有3,098名参与者回应了一项后续研究。通过排除基线调查中被归类为抑郁的1,030名参与者，分析了2,068名参与者的数据。使用多元逻辑回归计算赔率（OR），以评估与工作有关的事件对抑郁症状的影响。发现十六种事件是危险因素，分为以下四种类型：事故或灾难的经历（OR：4.78–7.67），过度责任感（OR：3.01-3.62），工作方式或工作量的急剧变化（OR： 2.38–3.08）和人际冲突（或：2.41–11.16）。当前的结果，包括OR的大小关系，应被用于促进心理健康的工作环境。工作方式或工作量的巨大变化（OR：2.38–3.08）和人际冲突（OR：2.41–11.16）。当前的结果，包括OR的大小关系，应被用于促进心理健康的工作环境。工作方式或工作量的巨大变化（OR：2.38–3.08）和人际冲突（OR：2.41–11.16）。当前的结果，包括OR的大小关系，应被用于促进心理健康的工作环境。
