徐州市0~7岁儿童身高、体重与体质指数研究

目的:对比世界通用的一些标准,建立徐州市0~7岁儿童年龄别身高(HFA)、年龄别体重(WFA)及年龄别体质指数(BM I)百分位标准及体质指数超重和肥胖界值点。方法:①采用分层整群随机抽样法,收集徐州市0~7岁儿童11 747例的性别、出生年月及2002~2004年身高和体重测量资料。②应用LMS方法建立徐州市0~7岁儿童HFA、WFA和BM I百分位曲线。结果:①运用LMS软件,分别获得0~7岁男女童HFA、WFA和BM I百分位曲线各9条,为P3、P5、P10、P25、P50、P75、P90、P95和P97。②徐州市男女童的身高随年龄不断增加,男童到6岁以后逐渐减缓,女童5岁后逐渐减缓。徐州市男女童的身高在7岁之前均大于WHO标准。③徐州市男女童的体重随年龄不断增加,到6岁以后均逐渐减缓。徐州市男女童体重7岁之前均高于WHO标准。④根据国际肥胖工作小组制定的7岁男女儿童肥胖和超重界值点,徐州市男女童7岁时通过该界值点的BM I百分位分别为:男童第72.6和第92.6,女童第82.1和第96.5。7岁男女童的超重流行率分别为27.4%和17.9%,肥胖流行率分别为7.4%和3.5%,在性别上存在差异。结论:应用LMS软件,获得了徐州市0~7岁儿童身高、体重和BM I百分位参考值。

A Study on growth references of height, weight and body mass index for Children aged 0-7 years in Urban Xuzhou

Objective:To study some percentage standards by comparing with the standards generally used in the world.The percentage standards included growth references of height for age(HFA),weight for age(WFA),body mass index(BMI) for Children aged 0-7 years in urban Xuzhou.And to develop the critical references of BMI for over-weight and fatness.Methods:①To compare other standards,randomized stratified clustered sampling method was used.The data of height and weight of 11 747 children(6 261 boys,5 486 girls),which measured in 2002~2004 in urban Xuzhou,were collected.②To construct the HFA,WFA and BMI percentage curve of the children aged 0~7 years in urban Xuzhou by using LMS method.Results:①By using LMS software,nine percentage curves of the children aged 0~7 years were plotted for HFA,WFA and BlVll respectively.They were percentage P3、P5、P10、P25、P50,P75,P90,P95 and P97 of the I-IFA,WFA and BMI.②The height of the children in urban Xuzhou grew with the age of them.But the curves became less sharply after age of 6 years for boys and 5 years for girls.The heights of boys and girls before the age of 7 years in Xuzhou were all higher than the standards of WHO.③The weight of the children in urban Xuzhou also kept increasing with the age of them.But the curves become less sharply after age of 6 years for both boys and girls.The weights of boys and girls before the age of 7 years in Xuzhou were all higher than those of WHO.④Based on the recommended BMI value of International Obesity Task Force on overweight and obesity cutoff points for children at age 7,the corresponding percentiles of these BMI value for Xuzhou boys were P72.6 and P92.6,and for Xuzhou girls were P82.1 and P96.5.The prevalence of overweight was 27.4% and 17.9% for Xuzhou boys and girls respectively at age 7.The prevalence of obesity was 7.4% and 3.5% for Xuzhou boys and girls respectively at age 7.Conclusion:The percentage references of the height,weight and BMI of the children aged 0~7 years in urban Xuzhou have been developed by using the LMS software.
