中国成年职业人群身体活动问卷的设计和评价

目的:设计“2002年中国居民营养与健康状况调查”中使用的“一年回顾身体活动调查表”,为描述我国居民身体活动现状、研究其与疾病及健康的关系提供依据。方法:采用专家讨论和查阅文献的方法,对调查表中涉及的职业劳动、交通、闲暇活动和家务劳动等4类身体活动进行强度赋值,提出总能量消耗和身体活动水平评价指标,并使用“食物频率调查表”计算出能量摄入量进行验证。结果:通过问卷计算的职业人群平均每天能量消耗为11.6MJ,男性11.9MJ,女性11.2MJ,身体活动水平(physical activity level,PAL)平均为1.95,男性1.88,女性2.02。能量消耗与能量摄入量之间存在显著的正相关关系(r=0.13)。结论:设计的“一年回顾身体活动调查表”可以较准确地反映调查对象的身体活动水平。

Objective: To design the “one-year physical activity questionnaire” used in 2002 China National Nutrition and Health Survey. Methods: The intensity of each activity in the questionnaire was assessed from literature review and experts consultation. The energy intake was calculated from food frequency questionnaire for validation of the physical activity questionnaire. Results: The average daily energy expenditure per capita estimated from the questionnaire was 11.6MJ (male 11.9MJ, female 11.2MJ). The average physical activity level (PAL) was 1.95 (male 1.88, female 2.02). There was significant correlation between energy expenditure and energy intake (r = 0.13, P<0.0001). Conclusion: The designed “one-year physical activity questionnaire” is valid and useful for nutrition survey.
