To assess the validity of a questionnaire for evaluating the physical activity of young children as reported by parents.
Twenty-one male 1st grade elementary school children were the study subjects. The questionnaire contained 3 questions relating to the physical activity of children and was completed by their parents. These questions were: preference for physical activity: like very much, like, don't like; physical activity compared to peers: more than, the same as, less than peers; time spent on exercise activity per day: <30 min, 30-60 min, 60 min or more. We also assessed physical activity more objectively, using a small instrument for calculating total steps, energy expenditure originating from exercise, and total energy expenditure per day. The contribution of the questionnaire items to the objective indices was evaluated by linear regression analysis.
Preference for physical activity was significantly associated with all the objective indices. Physical activity compared with peers had links with total energy expenditure. Time spent in activity was related to total steps and energy expenditure from exercise.
All the questionnaire items were valid measures for evaluating the physical activity level in young children and could be applied to a large epidemiological survey.
评估一份用于评估父母报告的幼儿身体活动的问卷的有效性。
21 名 1 年级男小学生为研究对象。问卷包含 3 个与儿童身体活动相关的问题，并由其父母完成。这些问题是：对身体活动的偏好：非常喜欢、喜欢、不喜欢；与同龄人相比的身体活动量：多于、与同龄人相同、少于同龄人；每天进行运动活动的时间：<30 分钟、30-60 分钟、60 分钟或更长时间。我们还使用一种小型仪器来更客观地评估身体活动，该仪器可计算总步数、运动产生的能量消耗以及每天的总能量消耗。线性回归分析评估了问卷项目对客观指标的贡献。
对身体活动的偏好与所有客观指标显著相关。与同龄人相比的身体活动与总能量消耗有关。活动时间与总步数和运动产生的能量消耗有关。
所有问卷项目都是评估幼儿身体活动水平的有效措施，可应用于大规模的流行病学调查。
