To establish BMI percentile curves that describe the contemporary BMI distribution among Chinese children, and to compare their BMI percentile curves with those in two recently developed international references: the WHO and the US Centers for Disease Control and Prevention (US CDC) growth references.
A cross-sectional national survey.
Thirty provinces, municipalities and autonomous regions in China.
Nationally representative sample of 232 140 school students aged 7-18 years.
BMI percentile curves were established using the LMS method, and were compared with the percentiles of the WHO and the US CDC references. BMI distributions and growth patterns in Chinese children were dramatically different from those in the two international reference populations. Compared with the international reference populations, younger Chinese boys (7-12 years of age) had higher values of the percentiles above the median and lower values of the percentiles below the median, suggesting that they had larger proportions of extreme BMI values in both directions. Chinese girls and older Chinese boys (15-18 years of age) had substantially lower BMI percentiles than their counterparts in the reference populations, particularly those high percentiles among older age groups.
The present study described the unique patterns of BMI curves at the national level, and these curves are useful as a reference for comparing different regions and for monitoring changes over time in Chinese children. Higher proportions of children with extreme values in both directions indicate that China is currently facing both an increasing level of obesity and a high level of undernutrition, simultaneously.
建立描述中国儿童当代 BMI 分布的 BMI 百分位曲线,并将其与最近开发的两种国际参考标准(WHO 和美国疾病控制与预防中心(USCDC)生长参考标准)的 BMI 百分位曲线进行比较。
一项横断面全国性调查。
中国 30 个省、直辖市和自治区。
来自全国代表性的 232140 名 7-18 岁学生的样本。
使用 LMS 方法建立了 BMI 百分位曲线,并与 WHO 和 USCDC 参考标准的百分位进行了比较。中国儿童的 BMI 分布和增长模式与这两个国际参考人群有显著差异。与国际参考人群相比,年龄较小的中国男孩(7-12 岁)的中位数以上百分位值较高,中位数以下百分位值较低,这表明他们在两个方向上的极端 BMI 值比例较大。中国女孩和年龄较大的中国男孩(15-18 岁)的 BMI 百分位值明显低于参考人群中的对应值,尤其是年龄较大的组别的较高百分位值。
本研究描述了全国范围内 BMI 曲线的独特模式,这些曲线可作为比较不同地区和监测中国儿童随时间变化的参考。在两个方向上极端值比例较高表明,中国目前同时面临肥胖水平的上升和营养不良水平的居高不下。
