| Outline of Final Research Achievements |
In the present study, we aimed to elucidate the risk factors that cause depression among individuals who work longer-than-normal hours. To achieve this, we administered a questionnaire to those who worked at least 60 hours of overtime each month, in addition to holidays. We planned to analyze the survey results; however, the participants’ data from the survey, as well as the questionnaire itself, needed to be reviewed to ensure the rationality and versatility of the analysis. Through this review, we clarified various aspects of our research. Additionally, through this questionnaire, we were able to obtain a portion of our target data and survey results, albeit fragmentary.

| Academic Significance and Societal Importance of the Research Achievements |
わが国の産業衛生の重要な課題である長時間労働が抑うつを引き起こすことが知られている一方、長時間労働者に精神的負荷を引き起こす危険要因は明らかではなく、産業衛生の現場において、産業医等による過重労働面談や労働衛生教育の際に長時間労働者に向けた効果的な指導法構築についての様々な情報把握が必要である中、本研究において、様々な情報収集が実現し、今後の更なる調査結果と併せて解析を行うことにより、長時間労働者が抑うつを引き起こす危険要因の明確化が期待できる。
