目的研究社会、生产和体力活动与老年人13年生存率之间的关系，设计前瞻性队列研究，每年随访死亡率。活动和其他措施进行了评估，在基线参与者的家中结构化访谈。比例风险模型被用来模拟从最初访谈时的生存率。设置城市纽黑文，康涅狄格州，美国。参与者2761名男性和女性，随机抽样的2812人年龄在65岁及以上。主要结果测量13年随访期间所有原因的死亡率。结果所有三种类型的活动与年龄，性别，种族/民族，婚姻状况，收入，身体质量指数;吸烟功能障碍和癌症，糖尿病，中风和心肌梗死的历史进行了控制。结论社会和生产活动，涉及很少或没有增强，健身降低风险的所有原因死亡率一样多的健身活动。这表明，除了增加心肺健康，活动可能会通过心理社会途径带来生存益处。需要较少体力活动的社会和生产活动可以补充锻炼方案，并可能成为体弱老年人的替代干预措施。
Objectives To examine any association between social, productive, and physical activity and 13 year survival in older people.Design Prospective cohort study with annual mortality follow up. Activity and other measures were assessed by structured interviews at baseline in the participants' homes. Proportional hazards models were used to model survival from time of initial interview.Setting City of New Haven, Connecticut, United States.Participants 2761 men and women from a random population sample of 2812 people aged 65 and older.Main outcome measure Mortality from all causes during 13 years of follow up.Results All three types of activity were independently associated with survival after age, sex, race/ethnicity, marital status, income, body mass index; smoking functional disability and history of cancer, diabetes, stroke, and myocardial infarction were controlled for.Conclusions Social and productive activities that involve little or no enhancement, of fitness lower the risk of all cause mortality as much as fitness activities do. This suggests that in addition to increased cardiopulmonary fitness, activity may confer survival benefits through psychosocial pathways. Social and productive activities that require less physical exertion may complement exercise programmes and may constitute alternative interventions for frail elderly people.
