背景随着社会老龄化，退休对于个人晚年变得越来越重要。本研究旨在描述日本中年/老年人退休前后的死亡率，特别关注社会经济地位和社会关系。方法我们进行了一项为期10年的跟踪研究（Komo-Ise队列研究），根据社会经济地位（相对贫困和职业）和社会关系（例如婚姻状况、独居和社会支持）评估工人和退休人员的死亡率。相对贫困的定义是2000年家庭等值收入为12,700美元（137万日元）或以下。根据性别对工人和退休人员两组就业状况进行分层分析。使用 Cox 比例风险模型计算调整后的风险比 (HR)。结果我们纳入了 5534 名个体。其中，男性 3360 人（在职 2499 人；退休 861 人），女性 2174 人（在职 1306 人；退休 868 人）。 We observed 610 deaths (475 in men and 135 in women) during the study period.相对贫困是退休男性死亡的重要危险因素（HR 1.52，95% CI 1.07-2.14），但在工作男性中则不然（HR 1.20，95% CI 0.79-1.83）。在工人中，个体经营者的死亡风险明显高于白领员工（HR 1.57，95% CI 1.09-2.25）。 Retired men who lacked participation in social activities were more likely to die than those who did not (HR 1.44, 95% CI 1.06-1.94).除婚姻状况外，所有结果均表明女性之间没有显着关联。结论相对贫困和缺乏社会参与可能与退休男性的高死亡率风险有关。需要进一步研究来评估中老年人群退休前后的健康状况。
BackgroundAs society is aging, retirement takes on increasing importance for individuals in the later life. This study aimed to describe mortality before and after retirement in the Japanese middle-aged/elderly with special attention to socioeconomic position and social relationships.MethodsWe conducted a 10-year follow-up study (the Komo-Ise cohort study) and assessed mortality according to socioeconomic positions (relative poverty and occupation) and social relationships (e.g., marital status, living alone, and social support) in workers and the retired. Relative poverty was defined as a household equivalent income of 12,700 US dollars (1.37 million Japanese Yen) or less in 2000. Stratified analyses were conducted according to sex in two groups of employment status: the workers and the retired. Adjusted hazard ratios (HRs) were calculated using the Cox proportional hazard model.ResultsWe included 5534 individuals. Of these, 3360 were men (working, 2499; retired, 861) and 2174 were women (working, 1306; retired, 868). We observed 610 deaths (475 in men and 135 in women) during the study period. Relative poverty was a significant risk factor for death (HR 1.52, 95% confidence interval [CI] 1.07-2.14) among retired men but not among working men (HR 1.20, 95% CI 0.79-1.83). Among workers, self-employed men showed a significantly higher hazard of death (HR 1.57, 95% CI 1.09-2.25) than white-collar employees. Retired men who lacked participation in social activities were more likely to die than those who did not (HR 1.44, 95% CI 1.06-1.94). All results, except marital status, indicated non-significant associations in women.ConclusionsRelative poverty and lack of social engagement may be related to high mortality risk in retired men. Further studies are needed to assess the health status among the middle-aged/elderly population around retirement.
