【摘要】：目的探讨儿童出生体重与肥胖之间的关联,为确定儿童肥胖的高危人群及制定相应防控措施提供依据。方法采用整群抽样方法,对北京市东城区12所小学7~11岁1 574名儿童进行体格检查,测量身高、体重并计算体质量指数。通过问卷调查收集儿童出生体重、视屏行为时间、运动及饮食情况等信息。采用Logistic回归控制肥胖的其他混杂因素后,分析儿童出生体重与肥胖的关联。结果正常出生体重组、低出生体重组和巨大儿组儿童的超重肥胖率分别为31.99%,27.03%和46.33%,肥胖率分别为17.43%,21.62%和28.81%,组间差异均有统计学意义(χ~2值分别为15.17,13.50,P值均0.01)。Logistic回归分析显示,在控制了儿童年龄、年级、性别、中高等强度活动时间、饮食评分、视屏行为时间、母乳喂养、母亲文化程度以及父母肥胖因素后,巨大儿组儿童肥胖发生风险是正常出生体重组的1.76倍(95%CI=1.17~2.67);而低出生体重组儿童肥胖发生风险与正常出生体重组差异无统计学意义(OR=1.45,95%CI=0.56~3.75)。结论高出生体重是儿童期肥胖的独立危险因素之一。预防儿童肥胖,除关注儿童饮食、行为习惯、遗传等因素外,还应关注儿童生命早期营养状态。
[Abstract]:Objective to explore the relationship between birth weight and obesity in children, and to provide evidence for the determination of high risk population of children obesity and the establishment of prevention and control measures. Methods 1 574 children aged 11 years from 7 to 11 years old in 12 primary schools in Dongcheng District of Beijing were examined by cluster sampling method. Height, weight and body mass index were measured. The information of birth weight, video time, exercise and diet were collected by questionnaire. After using Logistic regression to control other confounding factors of obesity, the relationship between birth weight and obesity in children was analyzed. Results the overweight and obesity rates of normal birth weight group, low birth weight group and macrosomia group were 31.99% and 46.33%, respectively, and the obesity rates were 17.4343% 21.62% and 28.81%, respectively. After controlling for children's age, grade, sex, activity time, dietary score, video behavior time, breastfeeding, mother's educational level, and parents' obesity factors, The risk of obesity in macrosomia group was 1.76 times higher than that in normal birth weight group (95%CI=1.17~2.67), but there was no significant difference between low birth weight group and normal birth weight group (OR=1.45,95%CI=0.56~3.75). Conclusion High birth weight is one of the independent risk factors for childhood obesity. In order to prevent childhood obesity, attention should be paid not only to children's diet, behavior and heredity, but also to the early nutritional status of children.
