上海市儿童青少年腰围百分位数值及曲线

Waist circumference and waist circumference percentile curves for children and adolescents in Shanghai

目的建立适合上海市儿童青少年生长发育特点的年龄别腰围、腰围指数的百分位数及曲线,为科学评价儿童青少年生长发育水平及中心性肥胖的防治提供参考。方法以2010年上海市学生体质健康调研的7～18岁中小学生14 301名为样本,应用国际通用的LMS法分性别建立年龄别腰围、腰围指数正常值及百分位数曲线。结果腰围百分位数曲线随年龄增长呈递增趋势,符合儿童青少年生长发育规律;腰围指数的P50百分位数曲线具有明显性别差异,7～12岁男生逐年上升,且高于女生,自13岁开始经交叉后低于女生。获得上海市7～18岁儿童青少年男女年龄别腰围、腰围指数百分位数(P5,P10,P15,P50,P85,P90,P95)及曲线。结论儿童青少年年龄别腰围、腰围指数百分位数存在地区、性别差异。本研究所获得的百分位数及曲线可为进一步研究儿童青少年中心性肥胖提供基本数据。

Objective To construct the age-and gender-specific waist circumference and waist-height-ratio percentile curves for children and adolescents in Shanghai and to provide data for the study of excess central adiposity in the group. Methods With stratified cluster sampling method, 14 301 students aged 7 - 18 years in Shanghai were selected as research subjects, LMS method was used to establish the centile curves. Results Age- and gender-specific percentiles of P5, P10, P15, P50, P85, P90 and P95 of waist circumference and waist-height-ratio and curves were accessed. Conclusion The centiles of waist circumference and waist-height-ratio percentile curves for children and adolescents in Shanghai have area and gender differences, and these data will provide a point of reference for the prevention of abdominal obesity.
