Regular physical activity can provide important health benefits, even when such activities are initiated later in life (1,2). Despite these benefits, most older persons in the United States have sedentary lifestyles (3). One of the national health objectives for the year 2000 is to reduce to 22% the proportion of adults aged > or = 65 years who engage in no leisure-time physical activity (objective 1.5a) (4). This report uses data from CDC's Behavioral Risk Factor Surveillance System (BRFSS) to summarize state-specific trends during 1987-1992 in the prevalence of physical inactivity during leisure time among persons aged > or = 65 years and projects state-specific prevalences for 1997.(ABSTRACT TRUNCATED AT 400 WORDS)
经常进行体育活动对健康大有裨益，即便这类活动是在晚年才开始的（1,2）。尽管有这些益处，但美国大多数老年人的生活方式都久坐不动（3）。2000年的一项国家健康目标是，将65岁及以上不参加任何休闲体育活动的成年人比例降至22%（目标1.5a）（4）。本报告利用疾病控制和预防中心行为危险因素监测系统（BRFSS）的数据，总结1987 - 1992年期间65岁及以上人群休闲时间身体不活动患病率的各州特定趋势，并预测1997年各州的患病率。（摘要截选至400字）
