This study examined the association between recreational physical activity among physically capable older adults and functional status, incidence of selected chronic conditions, and mortality over 3 and 6 years.
Data are from three sites of the Established Populations for Epidemiologic Studies of the Elderly.
A high level of recreational physical activity reduced the likelihood of mortality over both 3 and 6 years. Moderate to high activity reduced the risk of physical impairments over 3 years; this effect diminishes after 6 years. A consistent relationship between activity and new myocardial infarction or stroke or the incidence of diabetes or angina was not found after 3 or 6 years.
Findings suggest that physical activity offers benefits to physically capable older adults, primarily in reducing the risk of functional decline and mortality. Future work must use more objective and quantifiable measures of activity and assess changes in activity levels over time.
本研究调查了身体状况良好的老年人的休闲体育活动与功能状态、特定慢性病发病率以及3年和6年死亡率之间的关联。
数据来自老年人流行病学研究的三个既定人群研究地点。
高水平的休闲体育活动降低了3年和6年的死亡可能性。中度至高强度活动降低了3年身体功能受损的风险；6年后这种效果减弱。3年或6年后未发现活动与新发心肌梗死、中风、糖尿病或心绞痛发病率之间存在一致关系。
研究结果表明，体育活动对身体状况良好的老年人有益，主要是降低功能衰退和死亡风险。未来的工作必须采用更客观、可量化的活动测量方法，并评估活动水平随时间的变化。
