【摘要】 目的研究铜陵市区7～13岁儿童体质指数的分布特征。方法采用整群抽样的方法,随机抽取铜陵市区内2所小学,普查所有7～13岁小学生共3076名的身高和体重,分析BMI的年龄别分布特点,并与中国学龄儿童BMI超重、肥胖标准进行比较。结果铜陵市区7～13岁儿童中男性BMI均高于女性,随着年龄增长BMI有逐渐升高的趋势;选取拟合后的BMIP85、P95曲线作为铜陵市区儿童超重、肥胖的筛查标准,并将这一标准与全国标准进行比较显示,男童和女童在7～13岁BMI的P85、P95值均低于全国标准。结论铜陵市儿童BMI分布特征与全国标准有一定的差异,可以使用新建立的BMI标准进行本地区7～13岁儿童超重、肥胖的筛查及诊断。更多还原

【Abstract】 Objective To investigate the distribution profile of body mass index (BMI) in children aged from 7～13 years old in Tongling city.Methods Two primary schools in Tongling urban area were randomly selected by the method of cluster sampling, 3 076 students aged from 7～13 years old body weight and height were measured, BMI was calculated by one year interval from age 7 to 13 years old and its distribution pattern was compared with the Chinese BMI norm.Results All the BMI values of means, medians and percentiles of male children were significantly higher than those of female. And BMI values increased gradually with age. The BMI norm was established composed by cut- off points of P85 for overweight and P95 for obesity for Tongling children. Compared with the Chinese BMI norm, P85 and P95 were lower for Tongling male and female children aged from 7 to 13.Conclusion The BMI distribution characteristics of Tongling children aged from 7 to 13 are different from the Chinese BMI charts. New established BMI reference norm is suggested to be applied in screening and diagnosis of overweight and obesity for Tongling children aged from 7 to 13.更多还原
