目的：日本传统的终身雇用制度正在迅速改变。本研究的目的是评估最近在日本学术机构引入的任期限制就业制度对健康的影响。研究方法：共有514名研究人员（275名任期有限，239名终身教职）在年度健康检查的行为，身体和精神状态进行了比较。在这些检查中，工作时间和健康相关的生活方式进行了检查，使用自填问卷。结果：与终身制研究者相比，有任期限制的研究者工作时间更长（P < 0.001），饮酒更频繁（P <0.001），早餐吃得更少（P <0.001）。尽管两组的DSM-IV抑郁症患病率相当（P > 0.05），但在调整了年龄的影响后，任期有限的研究人员比任期跟踪的研究人员更容易疲劳（P=0.027）。与在同一实验室工作的同事相比，任期有限的研究人员工作时间更长，不考虑疲劳，而只有疲劳的终身研究人员工作时间更长。在总样本中，与不疲劳的研究人员相比，疲劳的研究人员往往属于他们的同事平均工作时间更长的实验室。结论：这些结果意味着，由于工作时间较长，任期有限的研究人员比他们的同事更容易疲劳，而且有组织，而不是个人，对工作环境的干预可能有效地减少这些工作场所的超负荷工作。(c)2005年，皇家公共卫生研究所。由爱思唯尔有限公司出版。保留所有权利。
Objectives: Traditional lifelong employment systems have been changing rapidly in Japan. The aim of this study was to assess the health impacts of term-limited employment systems that have recently been introduced into Japanese academic institutes.Study design: Cross-sectional. Methods: A total of 514 mate researchers (275 term limited and 239 tenure track) were compared in terms of behavioural, physical and mental status at annual health examinations. At these examinations, working hours and health-retated lifestyles were examined using a self-completed questionnaire. Clinical structured interviews of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) were used to detect major depression.Results: The term-limited researchers tended to work longer hours (P < 0.001), drink alcohol more frequently (P < 0.001) and eat breakfast less regularly (P < 0.001) compared with the tenure-track researchers. Although the prevalence of DSM-IV major depression was comparable (P > 0.05) between the two groups, fatigue was more prevalent (P=0.027) in the term-limited researchers than in the tenure-track researchers, adjusting for the effects of age. Compared with colleagues working in the same laboratories, the term-limited researchers worked longer hours, irrespective of fatigue, whereas only the fatigued tenure-track researchers worked longer hours. In the total sample, the fatigued researchers tended to belong to laboratories where their colleagues, on average, worked longer hours, compared with the non-fatigued researchers.Conclusions: These results imply that the term-limited researchers suffered more from fatigue, due to longer working hours, than their colleagues, and that organized, rather than personal, interventions with respect to the working environment may be effective in reducing overload in such workplaces.
