目的和方法：由于有规律的体力活动可以降低过早死亡和残疾的风险，准确的基于人群的测量方法对于公共卫生监测工作非常重要，例如基于行为危险因素监测系统(BRFSS)的监测工作。本研究：1)简要回顾和比较目前使用BRFSS数据测量体力活动的方法；2)描述美国使用这些国家综合测量方法的体力活动模式；3)为从业者和研究人员提供未来方向的建议。使用随机数字拨号，电话调查，我们收集了18岁及以上的非住院成年人的数据。我们分析了1996年来自50个州以及哥伦比亚特区和波多黎各(N=124,085)的BRFSS数据。根据最近的文献和公共卫生优先事项，我们制定了八个不同的体力活动指数(一个是剧烈的，七个是中等的)。这些活动的持续时间阈值、大卡支出以及活动频率和强度各不相同。结果：使用不同的算法，中度体力活动的人群患病率在20%到38%之间。只有20%的成年人符合2000年健康人对定期、持续活动的定义(每天至少进行5d·wk(-1)的中等强度活动大于或等于30分钟)。结论：如果美国要达到目前定期体育锻炼的公共卫生目标，还需要取得相当大的进展。分析和收集体力活动数据的标准化方法对于公共卫生监测、政策制定和与公众沟通至关重要。
Purpose and Methods: Because regular physical activity reduces the risk of premature death and disability, accurate methods of population-based measurement are important for public health surveillance efforts such as those based on the Behavioral Risk Factor Surveillance System (BRFSS). The present study: 1) briefly reviews and compares currently available methods to measure physical activity using BRFSS data, 2) describes physical activity patterns in the United States using these state-aggregated measures, and 3) provides suggestions on future directions for practitioners and researchers. Using a random-digit dialing, telephone survey, we collected data for noninstitutionalized adults aged 18 yr and older. We analyzed BRFSS data for 1996 from 50 states and the District of Columbia and Puerto Rico (N = 124,085). Based on recent literature and public health priorities, we developed eight different physical activity indices (one vigorous and seven moderate). These varied in their threshold for duration, kcal expenditure, and in frequency and intensity of activity. Results: Using different algorithms, the population prevalence of moderate physical activity ranged from about 20% to 38%. Only 20% of adults met the Healthy People 2000 definition for regular, sustained activity (greater than or equal to 30 min of moderate activity per day for at least 5 d.wk(-1)). Conclusions: Considerable progress is needed if the United States is to reach the current public health goal for regular physical activity. Standardized approaches to analyzing and collecting physical activity data are essential for public health surveillance, policy making, and communication to the public.
