背景体力活动（PA）通常与较低的全因死亡率有关，但美国现有的研究主要是基于非代表性样本。证据是缺乏的相对和独立的优点，休闲时间（LTPA）与非休闲时间（NLTPA）的活动，以及如何PA死亡率的链接可能会有所不同的种族，民族，性别groups.MethodsData从健康和退休研究开始于1992年收集数据的个人年龄在51-61岁，随后每2年调查一次。本研究评估了1992年测量的LTPA和NLTPA对1992-2008年随访期间发生的死亡率的组特异性影响。考克斯比例风险分析进行检查PA-mortality link.ResultsNet的广泛的控制，LTPA和NLTPA显示出梯度负相关的死亡率。没有明显的性别-PA相互作用效应。PA与种族间存在一定的交互作用，但交互作用较弱且不一致。PA的死亡率降低的影响似乎强大的种族，民族，性别groups. ConclusionsWhatever的个人背景，PA是一个主要的健康促进因素，应鼓励在老龄化人口。需要更多的研究来评估不同类型和领域的PA的相对优点。
BackgroundPhysical activity (PA) has been routinely linked to lower all-cause mortality, yet extant research in the United States is primarily based on nonrepresentative samples. Evidence is scant on the relative and independent merits of leisure-time (LTPA) versus non-leisure-time (NLTPA) activities and how the PA-mortality link may vary across racial-ethnic-gender groups.MethodsData were from Health and Retirement Study which began in 1992 collecting data on individuals aged 51–61 years who were subsequently surveyed once every 2 years. The current study assessed group-specific effects of LTPA and NLTPA measured in 1992 on mortality that occurred during the 1992–2008 follow-up period. Cox proportional hazard analyses were performed to examine the PA-mortality link.ResultsNet of a wide range of controls, both LTPA and NLTPA showed a gradient negative relation with mortality. No gender-PA interaction effects were evident. Some interaction effects of PA with race-ethnicity were found but they were weak and inconsistent. The mortality reduction effects of PA seemed robust across racial-ethnic-gender groups.ConclusionsRegardless of personal background, PA is a major health promoting factor and should be encouraged in aging populations. More research is needed to assess relative merits of different types and domains of PA.
