背景：了解和增加身体活动需要评估职业，家庭，休闲和久坐不动的活动。研究方法：身体活动问卷是使用来自美国大规模代表性样本的数据开发的;包括职业、休闲和家庭领域;并产生能量消耗、体脂百分比、各个领域的分钟数和会议建议的估计。在396人中进行了测试，平均年龄44岁。评估与双能X线吸收法测量的体脂百分比相关的估计值。结果：平均能量消耗为2,365千卡（女性）和2,960千卡（男性）。妇女每天花35.1分钟从事中等程度的家务活动，13.0分钟从事中等程度的休闲活动，4.0分钟从事剧烈活动。男性每天分别花18.0、22.5和15.6分钟从事这些活动。男性和女性每天花费276.4和257.0分钟进行久坐活动。通过剧烈活动达到建议的受访者的体脂百分比显著低于那些没有达到建议的受访者，而仅通过适度活动达到建议的受访者的体脂百分比与体脂百分比无关。预测和观察到的体脂百分比相关性分别为男性r = .73和女性r = .82，P < .0001。结论：这份问卷可能有助于了解活动的不同组成部分对健康的影响，并采取干预措施，以提高活动水平。
Background: Understanding and increasing physical activity requires assessment of occupational, home, leisure and sedentary activities. Methods: A physical activity questionnaire was developed using data from a large representative U.S. sample; includes occupational, leisure and home-based domains; and produces estimates of energy expenditure, percent body fat, minutes in various domains, and meeting recommendations. It was tested in 396 persons, mean age 44 years. Estimates were evaluated in relation to percent body fat measured by dual-energy x-ray absorptiometry. Results: Median energy expenditure was 2,365 kcal (women) and 2,960 kcal (men). Women spent 35.1 minutes/day in moderate household activities, 13.0 minutes in moderate leisure and 4.0 minutes in vigorous activities. Men spent 18.0, 22.5 and 15.6 minutes/day in those activities, respectively. Men and women spent 276.4 and 257.0 minutes/day in sedentary activities. Respondents who met recommendations through vigorous activities had significantly lower percent body fat than those who did not, while meeting recommendations only through moderate activities was not associated with percent body fat. Predicted and observed percent body fat correlated at r = .73 and r = .82 for men and women respectively, P < .0001. Conclusions: This questionnaire may be useful for understanding health effects of different components of activity, and for interventions to increase activity levels.
