A self-administered physical activity questionnaire (PA-questionnaire) was developed to assess daily energy expenditure and weekly physical activity in epidemiological studies. The Calorie Counter method (CC-method) was administered to 49 male and 32 female volunteers aged 18-64 years, on 7 consecutive days; after the measurement, the subjects were asked to complete the PA-questionnaire (validation study). The PA-questionnaire was completed by 95 males and 119 females (aged 35-73 years) twice with one-year interval (reliability study). The validation study showed that the mean daily energy expenditure estimated by the PA-questionnaire was slightly and significantly (4.5%) lower than that determined by the CC-method for males (p < 0.05); while no significant difference was observed for females (p > 0.05), mean weekly physical activities were similar between the PA-questionnaire and CC-method in males and females. Daily energy expenditures by the two methods strongly correlated with each other: r = 0.56 (p < 0.001) in males and r = 0.67 (p < 0.001) in females. Weekly physical activities by the two methods also strongly correlated with each other: r = 0.68 (p < 0.001) in males and r = 0.69 (p < 0.001) in females. The reliability study indicated that the Pearson's correlation coefficients between two assessments of daily energy expenditure and weekly physical activity over one-year ranged from 0.37 to 0.62 (p < 0.001). These data indicate that the PA-questionnaire has adequate levels of validity and test-retest reliability in assessment of daily energy expenditure and weekly physical activity in epidemiological studies.
为在流行病学研究中评估每日能量消耗和每周身体活动情况，研发了一份自我管理的身体活动问卷（PA问卷）。对49名年龄在18 - 64岁的男性志愿者和32名年龄在18 - 64岁的女性志愿者连续7天采用卡路里计数法（CC法）进行测量；测量后，要求受试者完成PA问卷（验证研究）。95名男性和119名女性（年龄在35 - 73岁）间隔一年两次完成PA问卷（信度研究）。验证研究表明，PA问卷估计的男性每日平均能量消耗比CC法测定的略低且具有显著性差异（4.5%）（p < 0.05）；而女性未观察到显著差异（p > 0.05），PA问卷和CC法测得的男性和女性每周身体活动情况相似。两种方法测得的每日能量消耗彼此高度相关：男性中r = 0.56（p < 0.001），女性中r = 0.67（p < 0.001）。两种方法测得的每周身体活动情况也彼此高度相关：男性中r = 0.68（p < 0.001），女性中r = 0.69（p < 0.001）。信度研究表明，在一年时间内对每日能量消耗和每周身体活动的两次评估之间，皮尔逊相关系数范围为0.37至0.62（p < 0.001）。这些数据表明，PA问卷在流行病学研究中评估每日能量消耗和每周身体活动时具有足够的效度和重测信度。
