目的 调查呼和浩特市学龄前(3~6岁)儿童肥胖症的发生率及生活方式、饮食习惯等因素与儿童肥胖的关系,为制定儿童肥胖干预策略提供理论依据。方法 采用分层整群抽样的方法,随机抽取呼和浩特地区6所幼儿园的2 800名在园儿童进行体格检查、身高和体重的测量,以WHO规定的标准体重加2s作为肥胖的判断标准。同时对这些儿童进行生活方式、运动情况和饮食习惯等的问卷调查,分析引起儿童肥胖可能的危险因素。结果 呼和浩特地区学龄前儿童超重率为15.3%,肥胖率为19.29%。其中男童肥胖率(23.8%)高于女童肥胖率(14.6%);城市儿童肥胖率(22.7%),高于农村肥胖率(13.6%);3~6岁各年龄组儿童肥胖发生率差异无统计学意义。分析显示:母亲孕期体重增长过高、高出生体重、人工喂养、父母超重、爱吃零食、喜吃肉类、常食用快餐食物,进食速度快、运动少及玩电脑看电视时间过长是儿童肥胖的危险因素。结论 呼和浩特地区学龄前儿童肥胖率较高,儿童肥胖的发生与家庭环境、饮食习惯及遗传等因素密切相关,应加强早期干预,控制儿童肥胖的发生。
