体力活动(PA)对老年人的好处已经被证明是在降低常见慢性病的患病率、改善心理健康、减少认知衰退和降低死亡率方面。关于轻到中等强度的PA对健康的影响，人们了解得较少。这项研究的目的是估计AARP医疗保险补充保险人中的轻中度PA频率水平-低(0-2天/周)、中等(3-4天/周)和高(>；=5天/周)-，确定特征，并估计PA水平与所选慢性病患病率、医疗保健利用率和支出的关系。2015年，对投保人的随机抽样进行了调查。PA是通过询问自我报告的每周至少30分钟的轻度到中度PA的调查响应来确定的。调整混杂协变量和调查无反应偏差的多元回归模型被用来确定中等和高度PA水平与健康结果的特征和关联。在第二个分析中，结果按年龄组分层：65-69岁，70-79岁，和=80岁。在17,676名受访者中，分别有23.3%、33.9%和42.9%的受访者从事低、中和高PA。中高PA的最强预测因素包括男性、年轻、自我报告的健康状况较好、较少使用处方药以及较不可能被诊断为常见的慢性病或抑郁症。那些从事中等和高PA的人，总体上和跨年龄组，医疗保健利用率和支出显著较低，大多数慢性病的患病率也较低。应鼓励在老年人中增加中等和高度PA水平的努力。
The benefits of physical activity (PA) for older adults have been demonstrated in reduced prevalence of common chronic conditions, improved mental health, decreased cognitive decline, and reduced mortality rates. Less is understood concerning the health impacts of light-to-moderate intensity PA. The purpose of this study was to estimate light-to-moderate PA frequency levels-low (0-2 days/week), intermediate (3-4 days/week) and high (>= 5 days/week)-among AARP Medicare Supplement insureds, identify characteristics, and estimate the association of PA levels with the prevalence of selected chronic conditions, health care utilization, and expenditures. In 2015, surveys were sent to a random sample of insureds. PA was determined from survey responses querying self-reported days per week of at least 30 minutes of light-to-moderate PA. Multivariate regression models, adjusting for confounding covariates and survey nonresponse bias, were utilized to determine the characteristics and association of intermediate and high PA levels with health outcomes. In a second analysis, results were stratified by age groups: 65-69, 70-79, and >= 80 years. Among survey respondents (n=17,676), 23.3%, 33.9%, and 42.9% engaged in low, intermediate, and high PA, respectively. The strongest predictors of intermediate and high PA included being male, younger, self-reporting better health, using fewer prescription drugs, and being less likely to be diagnosed with common chronic conditions or depression. Those engaged in intermediate and high PA, overall and across age groups, had significantly lower health care utilization and expenditures and lower prevalence of most chronic conditions. Efforts to increase intermediate and high levels of PA among older adults should be encouraged.
