背景：只有25%的美国成年人达到了足够的体力活动（PA）。在评估这种行为时，获取PA历史记录是适当的第一步。身体活动生命体征（PAVS）是一种临床工具，旨在筛查成人PA。研究方法：为了确定对PAVS问题的回答如何与BMI、超重和肥胖相关联，我们利用PAVS进行了一项横断面研究，并测量了身高和体重。数据收集自犹他州健康研究网络内2家诊所的成人。结果如下：调整人口统计学因素后，在典型的一周内，每报告一天的PA，BMI降低0.91个单位（P <0.001），在典型的一周内，每报告一天的PA，肥胖的几率显著降低0.73（P = 0.001）。结论：PAVS典型行为问题的回答与BMI高度相关。虽然响应PAVS问题的行为上周是不相关的，这个问题可能会提示准确的回忆到典型的一周的问题，并帮助指导患者咨询我们的研究结果支持使用的PAVS作为临床筛选工具的结构效度，并建议需要额外的研究来表征的属性的PAVS。
Background: Only 25% of US adults achieve adequate physical activity (PA). Obtaining a PA history is an appropriate first step when evaluating this behavior. The Physical Activity Vital Sign (PAVS) is a clinical tool designed to screen for PA in adults. Methods: To determine how responses to the PAVS questions associate with BMI, overweight, and obesity, we performed a cross-sectional study utilizing the PAVS, and measured height and weight. Data were collected from adults at 2 clinics within the Utah Health Research Network. Results: Adjusting for demographic factors, BMI decreased 0.91 units for every reported day of PA during a typical week (P < .001), and the odds of obesity was significantly decreased by 0.73 for every day of PA reported in a typical week, (P = .001). Conclusion: Response to the PAVS question of typical behavior is highly correlated with BMI. Although response to the PAVS question of behavior last week is not correlated, this question may prompt accurate recall to the typical week question and help guide patient counseling Our results support the construct validity for the use of the PAVS as a clinical screening tool and suggest the need for additional research to characterize the properties of the PAVS.
