Reproducibility and validity of the physical activity questionnaire (PAQ) used in the Shanghai Men's Health Study (2003-2006, People's Republic of China) was evaluated in a random sample of 196 participants aged 40-74 years. Participants completed a PAQ at baseline and again 1 year later, 12 monthly 7-day physical activity recalls, and four quarterly 1-week physical activity logs. Reproducibility was evaluated by using the two PAQs and validity by comparing the PAQs with 1-year averages of the two criterion measures: 7-day physical activity recall and physical activity log. The PAQ had moderate to high reproducibility for measuring adult exercise participation (kappa = 0.60) and energy expenditure (r(s) = 0.68), nonexercise activities (correlation coefficients = 0.42-0.68), and total daily energy expenditure (r(s) = 0.68, kappa(quartiles) = 0.47). Correlations between the PAQ and criterion measures of adult exercise were 0.45 (7-day physical activity recall) and 0.51 (physical activity log) for the first PAQ and 0.62 (7-day physical activity recall) and 0.71 (physical activity log) for the second PAQ. Correlations between PAQ nonexercise activities and the physical activity log and 7-day physical activity recall were 0.31-0.86. Correlations for total energy expenditure were high (0.62-0.77). Results indicate that the Shanghai Men's Health Study PAQ has reasonable reproducibility and validity for classifying men by their level of exercise and nonexercise activities in this cohort.
在196名年龄在40 - 74岁的随机抽样参与者中，对上海男性健康研究（2003 - 2006年，中华人民共和国）中使用的体力活动问卷（PAQ）的可重复性和有效性进行了评估。参与者在基线时完成一份PAQ，1年后再次完成，同时还有12次每月的7天体力活动回顾以及4次每季度的1周体力活动日志。通过两份PAQ评估可重复性，通过将PAQ与两种标准测量方法的1年平均值进行比较来评估有效性：7天体力活动回顾和体力活动日志。PAQ在测量成人运动参与度（kappa = 0.60）、能量消耗（r(s) = 0.68）、非运动活动（相关系数 = 0.42 - 0.68）以及每日总能量消耗（r(s) = 0.68，kappa(四分位数) = 0.47）方面具有中度到高度的可重复性。第一份PAQ与成人运动标准测量方法之间的相关性，7天体力活动回顾为0.45，体力活动日志为0.51；第二份PAQ与成人运动标准测量方法之间的相关性，7天体力活动回顾为0.62，体力活动日志为0.71。PAQ非运动活动与体力活动日志和7天体力活动回顾之间的相关性为0.31 - 0.86。总能量消耗的相关性较高（0.62 - 0.77）。结果表明，上海男性健康研究PAQ在根据该队列中男性的运动和非运动活动水平进行分类方面具有合理的可重复性和有效性。
