To develop waist circumference (WC) centile curves for UK South Asian children, to make comparisons with published centiles for British, indigenous Indian and Pakistani children, as well as to make anthropometric comparisons with their UK white peers.
Cross-sectional study.
School-aged children from London boroughs (main measures: 2004-2007).
1562 (652 boys, 910 girls) UK South Asian and 1120 (588 boys, 532 girls) UK white children aged 4.0-13.9 years.
WC, height, weight and body mass index (BMI).
The outcome measures were smoothed WC centile curves, constructed using the LMS (L = skewness, M = median, S = coefficient of variation) method. SD scores (SDS) were generated using UK90 and British (WC) growth references.
WC increased with age for both sexes, rising more steeply at the upper centiles after the age of 6 years. Overall, UK South Asian children, similar to indigenous South Asian populations, had higher WC values than the British WC references. However, compared with their UK white peers, UK South Asian children had significantly (p<0.001) lower mean WC (UK white SDS=0.74 and SDS=0.64 vs UK South Asian SDS=0.32 and SDS=0.21 for boys and girls, respectively). Obesity prevalence was greater using WC than BMI for both ethnicities. At the 90th centile, for UK South Asian children, prevalence was 21.5% vs 24.4% for boys and 17% vs 24.5% for girls based on BMI and WC, respectively.
These curves represent the first WC centiles for UK South Asian children up to the age of 14 years. With a continued rise in childhood obesity, they provide a useful historical control for future comparisons.
制定英国南亚儿童的腰围（WC）百分位曲线，与英国、印度本土和巴基斯坦儿童的已发表百分位曲线进行比较，并与英国白人同龄人进行人体测量学比较。
横断面研究。
伦敦自治市的学龄儿童（主要测量指标：2004-2007 年）。
1562 名（652 名男孩，910 名女孩）英国南亚儿童和 1120 名（588 名男孩，532 名女孩）英国白人儿童，年龄 4.0-13.9 岁。
WC、身高、体重和体重指数（BMI）。
使用 LMS（L =偏度，M =中位数，S =变异系数）方法构建的平滑 WC 百分位曲线。SD 分数（SDS）是使用 UK90 和英国（WC）生长参考值生成的。
男女 WC 均随年龄增长而增加，6 岁后在上百分位处增长更为陡峭。总体而言，英国南亚儿童与印度本土南亚人群一样，WC 值高于英国 WC 参考值。然而，与英国白人同龄人相比，英国南亚儿童的 WC 平均值明显较低（p<0.001）（英国白人 SDS=0.74 和 SDS=0.64，男孩和女孩分别为 SDS=0.32 和 SDS=0.21）。对于两个种族，WC 比 BMI 更能准确地反映肥胖的流行情况。在第 90 百分位，对于英国南亚儿童，基于 BMI 和 WC，男孩的肥胖患病率分别为 21.5%和 24.4%，女孩的肥胖患病率分别为 17%和 24.5%。
这些曲线代表了英国南亚儿童截至 14 岁的第一批 WC 百分位曲线。随着儿童肥胖率的持续上升，它们为未来的比较提供了一个有用的历史对照。
