To derive age- and sex-specific reference values for waist circumference (WC) and waist-to-height ratio (WHtR) for Han Chinese children and adolescents and to establish the prevalence of excess central adiposity in our study population.
Cross-sectional study of schoolchildren attending randomly selected primary and secondary schools in south-west China in October 2003 and April 2004. Anthropometry was measured using standard procedures. The LMS method was used to construct smoothed WC and WHtR percentile curves. Overweight and obesity were defined by the International Obesity Task Force (IOTF) criteria and the Working Group on Obesity in Children. Excess central adiposity fat was defined by previously published WC cut-points and a WHtR ≥ 0.5.
Primary and secondary schools in Chongqing, south-west China.
A total of 7326 (49.2 % boys) Han Chinese students at 5-17 years old.
On the basis of the IOTF criteria, 26.4 % of boys were overweight or obese compared with 16.4 % of girls (P < 0.001). WC cut-points identified 31 % of boys and 28 % of girls as having excess central adiposity, whereas using the WHtR criterion, 14.8 % of boys and 5.6 % of girls were identified. Young boys (5-12 years) had a significantly (P < 0.001) higher WHtR than girls.
We have constructed WC and WHtR percentile curves for Han Chinese children and adolescents living in Chongqing. Our measurements were based on a student population with a relatively high rate of overweight and obesity. These data will provide a point of reference for future studies measuring the prevalence of overweight and obesity in China.
制定中国汉族儿童青少年腰围（WC）和腰高比（WHtR）的年龄和性别特异性参考值，并确定本研究人群中中心性肥胖的流行情况。
2003 年 10 月至 2004 年 4 月，在中国西南部的随机选择的小学和中学的学生进行横断面研究。使用标准程序测量人体测量学。使用 LMS 方法构建 WC 和 WHtR 百分位数曲线的平滑曲线。超重和肥胖按照国际肥胖工作组（IOTF）标准和儿童肥胖工作组定义。使用先前发表的 WC 切点和 WHtR≥0.5 定义过多的中心性肥胖脂肪。
中国西南部重庆市的小学和中学。
共 7326 名（49.2%为男生）5-17 岁汉族学生。
根据 IOTF 标准，26.4%的男生超重或肥胖，而女生为 16.4%（P<0.001）。WC 切点确定 31%的男生和 28%的女生存在中心性肥胖，而 WHtR 标准确定 14.8%的男生和 5.6%的女生存在中心性肥胖。年轻男孩（5-12 岁）的 WHtR 明显高于女孩（P<0.001）。
我们为居住在中国重庆的汉族儿童青少年构建了 WC 和 WHtR 百分位数曲线。我们的测量是基于超重和肥胖率相对较高的学生人群进行的。这些数据将为未来研究中国超重和肥胖的流行情况提供参考点。
