背景资料：到目前为止，还没有研究根据2008年美国人身体活动指南（PAGA）客观地测量美国成年人的身体活动水平。目的：本研究的目的是根据PAGA评估美国成年人自我报告和客观测量的身体活动。方法：使用NHANES 2005-2006的数据，使用三种体力活动计算来评估PAGA：中等加剧烈体力活动>= 150分钟/周（MVPA）;中度加两次剧烈体力活动>= 150分钟/周（M2 VPA）;以及花费超过3 MET的时间>= 500 MET-分钟/周（METPA）。自我报告的身体活动包括休闲，交通和家庭活动。使用连续佩戴7天的Actigraph加速度计测量客观活动。2009- 2010年进行了分析。结果：美国成年人报告324.5 +/- 18.6分钟/周（M +/- SE）中度体力活动和73.6 +/- 3.9分钟/周的剧烈体力活动，尽管加速度测量法估计为45.1 +/-4.6分钟/周的中等体力活动和18.6 +/-6.6分钟/周的剧烈体力活动。成年人满足PAGA根据M2 VPA的比例为62.0%的自我报告和9.6%的accelerometer.Conclusions：根据NHANES 2005-2006，不到10%的美国成年人满足PAGA根据加速度。然而，身体活动估计值根据自我报告或通过加速度计测量而变化很大。(Am J Prev Med 2011;40（4）：454-461）（C）2011年美国预防医学杂志
Background: To date, no study has objectively measured physical activity levels among U.S. adults according to the 2008 Physical Activity Guidelines for Americans (PAGA).Purpose: The purpose of this study was to assess self-reported and objectively measured physical activity among U.S. adults according to the PAGA.Methods: Using data from the NHANES 2005-2006, the PAGA were assessed using three physical activity calculations: moderate plus vigorous physical activity >= 150 minutes/week (MVPA); moderate plus two instances of vigorous physical activity >= 150 minutes/week (M2VPA); and time spent above 3 METs >= 500 MET-minutes/week (METPA). Self-reported physical activity included leisure, transportation, and household activities. Objective activity was measured using Actigraph accelerometers that were worn for 7 consecutive days. Analyses were conducted in 2009-2010.Results: U.S. adults reported 324.5 +/- 18.6 minutes/week (M +/- SE) of moderate physical activity and 73.6 +/- 3.9 minutes/week of vigorous physical activity, although accelerometry estimates were 45.1 +/- 4.6 minutes/week of moderate physical activity and 18.6 +/- 6.6 minutes/week of vigorous physical activity. The proportion of adults meeting the PAGA according to M2VPA was 62.0% for self-report and 9.6% for accelerometry.Conclusions: According to the NHANES 2005-2006, fewer than 10% of U.S. adults met the PAGA according to accelerometry. However, physical activity estimates vary substantially depending on whether self-reported or measured via accelerometer.
