背景：一般人群的体力活动（PA）水平很难描述。从历史上看，测量一直是基于自我报告，这可能会受到偏见。PA监测器的使用为改善对活动和健康的监测和分析研究创造了机会。当前研究的目的是调查客观测量的PA与心血管疾病危险因素和肥胖之间的相关性。方法：在2003-2006年NHANES调查中，获得了20-65岁成年人的加速计、人口统计学、血压、血糖和血脂、自我报告的高血压和糖尿病的PA数据。结果评估为中度和剧烈活动水平、符合推荐指南的参与者百分比以及活动与心血管风险因素之间的相关性。3,370名成年人提供了加速度计数据。根据标准算法，活动水平极低，在所有年龄，性别，种族/民族组，平均只有1回合的剧烈活动持续时间超过1分钟/day.Results：男子花35分钟在中度活动/天，妇女21分钟，> 75%的这种活动是积累在1分钟的回合。在所有群体中，50岁以后的活动水平急剧下降。中度和剧烈运动的时间与收缩压、血糖、糖尿病、高血压、体重指数和肥胖呈负相关，与高密度脂蛋白胆固醇呈正相关（均P
Background: Levels of physical activity (PA) in the general population are difficult to characterize. Historically measurement has been based on self-report, which can be subject to bias. PA monitor use has created opportunities to improve surveillance and analytic research on activity and health. The aims of the current study were to investigate the associations between objectively measured PA and cardiovascular disease risk factors and obesity.Methods: Data on PA from accelerometers, demographics, blood pressure, plasma glucose and lipids, self-reported hypertension and diabetes were obtained for adults, ages 20-65, in the NHANES surveys, 2003-2006. Outcomes were assessed as levels of moderate and vigorous activity, percentage of participants meeting recommended guidelines, and the correlations between activity and cardiovascular risk factors. Accelerometry data were available on 3,370 adults. Based on standard algorithms, activity levels were extremely low in all age-gender-race/ethnic groups, with an average of only 1 bout of vigorous activity lasting longer than 1 minute/day.Results: Men spent 35 minutes in moderate activity/day, women 21 minutes; > 75% of this activity was accumulated in 1-minute bouts. Levels of activity declined sharply after age 50 in all groups. Negative associations were observed between minutes of combined moderate and vigorous activity and systolic blood pressure, blood glucose, diabetes, hypertension, body mass index and obesity, and a positive association was seen with HDL-cholesterol (all P
