Logistic regression analysis on influence factors of childhood simple obesity among school age children

目的研究学龄儿童单纯性肥胖(CSO)的影响因素,为探讨干预对策提供依据.方法采用多阶段分层整群抽样,对徐州市8所小学1～5年级学生进行问卷调查与体检,所得资料采用SPSS 11.5软件进行单因素与多因素非条件Logistic回归分析.结果经单因素和多因素Logistic回归分析,有8个暴露因素为危险因素,可归结为父、母亲肥胖、儿童出生与周岁体重过大和不良饮食方式等;有4个因素具有保护作用,主要为儿童的合理喂养和适当的运动;儿童的出生体重、周岁体重、进食速度、喜食肥肉、主食量大和适量运动的等级间OR值较大.结论徐州市学龄儿童单纯性肥胖的影响因素以营养过度和饮食行为偏差更为突出,家长、学校以及社区应创造一个综合防治的社会环境,才能有利于儿童肥胖的群体干预.
