Patterns of leisure time sedentary behaviors and physical activities among children

【目的】了解中国儿童课余时间内静态活动和体力活动的分布模式。【方法】采用2006年中国健康和营养调查的数据,选择666名6～11岁的在校儿童,比较和分析静态活动和体力活动的时间分布。【结果】不论周中或周末,6～11岁儿童花费时间最多的静态活动依次为看电视,做家庭作业,读书、写字或画画。周末每天看电视≥2 h的孩子明显多于周中(P<0.05)。不论周中或周末,60%～70%的儿童每天做家庭作业≥1 h,40%～50%的儿童每天读书、写字或画画≥30 min,大多数儿童很少参加体育活动和家务劳动。【结论】中国6～11岁儿童大部分课余时间用于静态活动。
