学龄前单纯性肥胖儿童运动行为特征分析

Characteristics analysis on motor behavior of preschool simple obese children

目的了解学龄前单纯性肥胖儿童运动行为特征,为制订肥胖儿童运动处方提供依据。方法随机整群抽取海门市市区、农村各4所幼儿园共30个班级中所有单纯性肥胖儿童,按照1∶1配对正常儿童,调查运动行为特征。结果发现肥胖儿童园外体育运动的频率低于非肥胖儿童(χ~2=10.766,P<0.05),放学后留在幼儿园参与大型玩具活动也少(χ~2=45.006,P<0.01),非肥胖儿童的平均体育运动时间为22.5 min,而正常儿童为28.6min,肥胖组儿童喜欢散步、跑步、玩球,非肥胖组儿童更喜欢玩球、骑车、跳舞,肥胖组大运动发育商较低。结论肥胖儿童的日常体育运动水平较低、活动时间较短,更倾向于身体移动较小、技巧性较低的运动项目23。

Results It was found that activity frequency of preschool obese children was lower than that of normal children （x^2 = 10. 766 , P 〈 0. 05 ）. Activity frequency of large toys in kindergarten after school in obese children was lower than that in normal children （x^2 = 45. 006, P 〈 0. 01 ）. The average time for activity in obese children was 22.5 minutes, and that in normal children 28.6 minutes.
