父母肥胖对儿童期肥胖的影响

Influence of Parental Overweight on Development of Childhood Obesity

目的 探讨父母肥胖对儿童期肥胖的影响。方法 以北京市近万名 6～ 8岁儿童为调查对象 ,测量其身高、体重 ,并发放调查问卷以获得父母的身高与体重。以体重超过身高标准值的 12 0 %为标准筛选出肥胖儿童 ,以BMI超过2 5或 2 8kg/m2 为标准筛选出超重或肥胖家长。结果 当父亲正常、超重及肥胖时儿童肥胖率分别为 12 3% ,2 0 0 %和 2 5 0 % ,当母亲正常、超重及肥胖时儿童肥胖率分别为 13 8% ,2 6 5 %和 30 0 % ,各组的肥胖率之间差别显著。父母均正常的儿童肥胖发生率为 11 1% ,而父母均超重或肥胖的儿童肥胖率则上升至 33 6 %。儿童BMI与父亲和母亲BMI均明显相关 ,相关系数分别为 0 195和 0 2 14。结论 父母肥胖是儿童肥胖的重要危险因素 ,父母肥胖的儿童应成为预防肥胖的重点人群。

ObjectiveTo assess the influence of parental overweight on the development of obesity in children.MethodsA total of 9 325 children aged between 6-8 years were studied.Height and weight of children were measured and that of parents were self-reported.Children whose weight exceeded 120% of that expected for their height were defined to be obese.ResultsThe prevalene of obesity in children was 12.3%,20.0% and 25.0% respectively when their fathers were normal,overweight and obese.The prevalence was 13.8%,26.5% and 30.0% repsectively when their mothers were normal,overweight and obese.The prevalence of obesity in children was 11.1% if neither parents was overweight,and this prevalence rose to 33.6% if both parents were overweight.The BMI of children was correlated markedly with maternal BMI( r =0.214) and also with paternal BMI( r =0.195).ConclusionParental overweight was a predictor of childhood obesity.It was important and necessary to prevent obesity in children with one or two overweight parents.
