Results It was found that three variables exerted a significant influence on the physical fitness of the preschool children,that was,participation in sports and art classes (P=0.004),daily sleep classification (P=0.009) and daily dynamic physical activity time (P=0.040).

摘要： 目的 通过大样本横断面研究,初步探讨部分现代生活方式对幼儿体质健康的影响及其二者的关系。方法 在2010年国民体质监测幼儿库中,选取上海市18个县区共7 643名3~6岁学龄前幼儿为调查对象,选取出生后四个月内喂养方式、在家看护人、日睡眠情况、是否参加体育文艺特长班、父亲、母亲是否体育锻炼为7个自变量,幼儿综合体质健康评价作为因变量。采用二分类 logistic 回归进行分析。结果 上海市3~6岁学龄前幼儿综合评级中总体合格率为94%,优秀和良好才达到42.95%。是否参加体育/文艺特长班(P=0.004)、日睡眠分类(P=0.009)、每日动态体力活动时间(P=0.040)三个变量对幼儿体质健康存在显著性影响。结论 上海市3~6岁学龄前幼儿综合评级总体合格率虽然较高,但“高质量”的体质比例不多,并呈现出“女强男弱”的体质趋势;可从提高体力活动量和日睡眠时间两方面来提高幼儿体质。
