目的分析北京市怀柔区3~6岁学龄前儿童单纯性肥胖的影响因素,为早期干预提供依据。方法采用分层整群抽样、病例对照研究的方法,对396例学龄前儿童进行家长自填问卷调查,Logistic回归分析其影响因素。结果父母平均体重肥胖组高于正常组(P<0.001)。父亲高体重(OR=1.082)、生后6个月采用人工喂养(OR=5.986)、每餐以肉为主(OR=7.979)、强迫儿童进食某种食物(如高能量食物)(OR=4.801)、家长对儿童体重过高预期(OR=6.191)为学龄前儿童肥胖的危险因素;家长控制儿童体重的行为(OR=0.059)为学龄前儿童肥胖的保护因素。结论学龄前儿童肥胖的发生是多因素相互作用的结果,其中从控制父母体重、鼓励母乳喂养、平衡膳食等方面早期干预,将有益于早期预防儿童肥胖。
Objective To analyze the influencing factors of simple obesity in preschool children aged 3 ~ 6 years in Huairou District, Beijing, and provide the basis for early intervention. Methods By stratified cluster sampling and case-control study, 396 preschool-aged children were investigated by self-administered questionnaire and Logistic regression analysis was used to analyze the influencing factors. Results The average weight and fatness of parents was higher than that of normal group (P <0.001). (OR = 5.979), each meal was dominated by meat (OR = 7.979), forcing children to eat certain foods (such as high-energy foods) (OR = 4.801). Expectant parents were overweight children (OR = 6.191), which were the risk factors for preschool children’s obesity. Parental control of children’s weight (OR = 0.059) was a protective factor for preschool children’s obesity. Conclusion The incidence of obesity in preschool children is the result of multi-factor interaction. Among them, the early intervention in controlling the weight of the parents, encouraging breast-feeding and balancing the diet will be beneficial to the early prevention of childhood obesity.
