摘 要: | 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(x2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 association between birth weight and obesity in children,and to provide references for making preventive measures for the high-risk children of obesity.Methods A total of 1 574 children aged 7-11 years from 12 primary schools in Dongcheng district of Beijing were selected to have a physical examinationincluded in the study.The data of Their their body weight and height was measured to calculate the body mass index.Questionnaires were used to collect relevant information including birth weight,screen-based sedentary behaviors,moderate to vigorous physical activity and dietary status.Logistic regression model was employed to analyze the association between birth weight and obesity after adjustment of other potential risk factors.Results The total prevalence of overweight and obesity in normal birth weight group,low birth weight group and macrosomia group were 31.99%,27.03% and 46.33%,respectively.The prevalence of obesity were 17.43%,21.62% and 28.81% in the three groups(x2 =15.17,13.50,P<0.01).Logistic models showed that the risk of obesity during childhood in macrosomia group was 1.76 times higher than that in normal birth weight group(95%CI=1.17-2.67).The difference of obesity prevalence during childhood between low birth weight group and normal birth weight group was not statistically significant(OR=1.45,95%CI=0.56-3.75).Conclusion Macrosomia is independently associated with childhood obesity.In addition to the diet,behavior,genetic factors,the childhood obesity in the early stage should also be focused on to prevent the childhood obesity. |
