目的了解学龄前单纯性肥胖儿童身体素质状况,探讨单纯性肥胖对儿童素质的影响。方法随机分层整群抽取8所幼儿园,对在园儿童进行健康体检,按身高标准体重并排除病理性肥胖,筛选出肥胖儿童216名作为病例组,按1∶1配对原则,选择体重正常儿童为对照组,以统一方法检测2组儿童身体素质,进行身体素质综合评级比较。结果肥胖组儿童身体素质综合评级达标率68.05%,其中优秀率0.46%、良好率5.09%、合格率62.50%;对照组达标率为93.98%,其中优秀率9.25%、良好率25.92%、合格率58.79%,两组比较差异有统计学意义(P<0.05)。肥胖儿童立定跳远、坐位体前屈、网球掷远成绩差于对照组,10米折返跑、走平衡木、双脚连续跳所需时间肥胖组多于对照组。立定跳远、走平衡木、双脚连续跳3个项目指标比较差异有统计学意义(P<0.05)。结论单纯性肥胖可导致学龄前儿童身体素质下降,对儿童健康造成危害。

Objective To understand the physical quality status of preschool children with simple obesity of,and to explore the influence simple obesity on the quality of children. Method Random stratified cluster sampling was used and 8 kindergartens were selected,health checks was carried out on children in these kindergartens,216 obese children were screened as case group according to the standard of height weight and excluding pathological obesity,according to the principle of 1:1 matched,216 children with normal weight were select as control group.
