To provide data as age-gender dependent mean, standard deviation and percentile on height, weight, waist circumference (WC), hip circumference (HC), body mass index (BMI), waist hip ratio (WHR), waist to height ratio (WHtR) among 7-16 year-olds Chinese children and adolescents, towards setting up diagnostic criteria on metabolic syndrome for them.
A representative sample involving 22,197 children and adolescence aged 7 to 16 years were randomly surveyed and they were from 6 representative geographical areas, including Beijing, Tianjin, Hangzhou, Shanghai, Chongqing and Nanning. A total of 21 858 had available data, with male/female ratio as: 11,460/10,398. Using the standard methods, we measured height, weight, WC, HC, BMI, WHtR and other data in all age groups. Physique indexes among different geographic regions (North, Mid-west and East) were compared.
(1) Both male and female showed an increasing trend of height, weight, waist circumference, hip circumference and BMI along with the increase of age. WHR of girls decreased gradually from 0.84 to 0.76 went from 7 to 16 years old while WHR of boys changed from 0.87 to 0.81 accordingly. (2) WHtR was rarely affected by age. It fluctuated between 0.42-0.43 in all girls and 0.44-0.45 in boys less than 11 years. WHtR of boys older than 12 years showed a slight decline from 0.45 to 0.42 of WHtR. (3) The average height, weight, BMI of children and adolescents from the northern regions (Beijing, Tianjin) were significantly higher than that of the mid-western (Chongqing, Nanning) and the eastern regions (Shanghai, Hangzhou) (P<0.001), while those from the mid-western region were slightly higher than that of the eastern region (P<0.05) in each of the age group.
Reference values and percentile curves for WC and WHtR of Chinese children and adolescents were provided. For the assessment of central obesity. WHtR had the advantages of relative stability and small degree of variation and rarely affected by age and gender, when compared with WC, and could be used as an simple index to reflect the central obesity of children and adolescents.
提供7至16岁中国儿童和青少年身高、体重、腰围（WC）、臀围（HC）、体重指数（BMI）、腰臀比（WHR）、腰高比（WHtR）的年龄和性别相关均值、标准差及百分位数数据，为制定其代谢综合征诊断标准提供依据。
随机调查了来自北京、天津、杭州、上海、重庆和南宁6个代表性地理区域的22197名7至16岁儿童和青少年作为代表性样本。共有21858人有可用数据，男/女比例为：11460/10398。采用标准方法测量了所有年龄组的身高、体重、腰围、臀围、体重指数、腰高比等数据。比较了不同地理区域（北方、中西部和东部）的体格指标。
（1）男、女身高、体重、腰围、臀围和体重指数均随年龄增长呈上升趋势。女孩的腰臀比从7岁到16岁逐渐从0.84降至0.76，而男孩的腰臀比相应地从0.87变为0.81。（2）腰高比受年龄影响较小。所有女孩的腰高比在0.42 - 0.43之间波动，11岁以下男孩的腰高比在0.44 - 0.45之间。12岁以上男孩的腰高比从0.45略有下降至0.42。（3）北方地区（北京、天津）儿童和青少年的平均身高、体重、体重指数显著高于中西部地区（重庆、南宁）和东部地区（上海、杭州）（P<0.001），而中西部地区在各年龄组中略高于东部地区（P<0.05）。
提供了中国儿童和青少年腰围和腰高比的参考值及百分位数曲线。对于中心性肥胖的评估，与腰围相比，腰高比具有相对稳定、变异程度小且很少受年龄和性别的影响的优点，可作为反映儿童和青少年中心性肥胖程度的简易指标。
