背景：关于多重角色效应的两种截然不同的观点：“角色过载假说”和“角色增强模型”，已经被提出来预测健康的变化。本研究的目的是评估多个角色对全因死亡率的影响，在日本的性别角色目前正在改变。方法：从日本协作队列研究，共76 758人进行了跟踪，平均为15.7年。从比例风险模型计算风险比（HR）与95%的置信区间，以估计全因死亡的风险，根据多个角色（配偶，父母和工人，以及这些角色的组合）。结果：调整潜在的混杂因素后，全因死亡的风险升高的男性和女性没有一个角色。角色的数量也与全因死亡风险相关，与三重角色相比，没有角色的风险值最高（男性HR：1.66，女性HR：1.78）。的影响，缺乏一个角色，一般是男性比女性，也在中年比老年人。结论：一个有益的影响，多个角色之间的建议日本。他们的角色越少，观察到的全因死亡风险就越高。那些角色较少的人的风险值在男性中普遍高于女性，在中年人中也高于老年人，部分原因是中年女性比日本其他群体的角色过载更大。
Background:Two contrasting perspectives on the effects of multiple roles; the ‘role overload hypothesis’ and the ‘role enhancement model’, have been proposed to predict variations in health. The aim of this study was to evaluate the impact of multiple roles on all-cause mortality in Japan where gender roles are currently changing.Methods:A total of 76 758 individuals from the Japan Collaborative Cohort Study were followed for an average of 15.7 years. Hazard ratios (HRs) with 95% confidence intervals were calculated from proportional hazard models to estimate the risk of all-cause mortality according to multiple roles (spouse, parent and worker, and combinations of these roles).Results:After adjusting for potential confounding factors, the risks of all-cause mortality were elevated among men and women without a role. The number of roles was also associated with all-cause mortality risk, showing the highest risk values among those with no roles compared with those with triple roles (HR: 1.66 in men and 1.78 in women). The impact of the lack of a role was generally greater in men than in women and also in the middle-aged than in the elderly.Conclusion:A beneficial effect of multiple roles was suggested among Japanese. The fewer roles they had, the higher all-cause mortality risks were observed. The risk values of those with fewer roles were generally higher in men than in women and also in the middle-aged than in the elderly, partially explained by greater role overload in middle-aged women than other groups in Japan.
