背景。了解老年人开始和维持积极生活方式的决定因素与公共卫生密切相关，因为越来越多的证据表明，生活方式可能改变经常发生的慢性病的病程。方法对2500名65岁及以上的社区医疗保险受益人进行了为期4年的三个时间点的身体活动采访，定义为每周至少三次快步走、园艺或繁重家务的自我报告。还收集了大量关于健康状况、卫生服务使用、社会人口统计数据，并在最后的访谈中收集了自我控制、决定进行体育锻炼的各种因素的重要性以及与医生就体育锻炼进行互动的数据。使用逻辑回归确定了开始和维持体力活动的决定因素。41%的人保持积极的生活方式；12%的人开始积极的生活方式；22%的人拒绝久坐；25%的人在观察期间久坐不动。开始和维持体力活动的预测因子为年龄较年轻、健康状况中等至良好，以及患者认为体力活动对其健康很重要。在301名开始运动的患者中，40%的人说他们的医生对他们有非常重要的影响。加强老年人对身体活动对其健康有益的信念，有望增加社区居住老年人从久坐不动的生活方式转向更积极的身体活动生活方式的比例，并保持这种活动。(C) 1999年美国卫生基金会和学术出版社。
Background. Understanding determinants of initiation and maintenance of an active lifestyle among older individuals is of great concern to public health because of the increasing evidence that lifestyle may alter the course of frequently occurring chronic diseases.Method Two thousand five hundred seven community-dwelling Medicare beneficiaries age 65 and over were interviewed at three points over 4 years regarding their physical activity, defined as a self-report of walking briskly, gardening, or heavy housework, at least three times a week. Extensive data were also collected on health status, health services use, sociodemographics, and, at the final interview, self-mastery, importance of various factors in the decision to be physically active, and interaction with their physician regarding physical activity. Determinants of initiation and maintenance of physical activity were identified using logistic regressions.Results. Forty-one percent maintained an active lifestyle; 12% initiated an active lifestyle; 22% declined to become sedentary; 25% were sedentary at all observation. Predictors of both initiation and maintenance of physical activity were younger age, moderate to excellent health, and the patient's belief that physical activity was important to his/her health. Among the 301 patients who initiated activity, 40% said their physician was a very important influence.Conclusions. Strengthening the belief of older individuals in the benefits to their health of physical activity holds promise for increasing the proportion of community-dwelling older persons who move from a sedentary lifestyle to a more physically active lifestyle and for maintaining such activity.
