本研究的目的是使用一系列肥胖标记来检查英国南亚、非洲加勒比黑人和欧洲白人儿童的肥胖模式。在伦敦、伯明翰和莱斯特的小学进行了横断面调查。测量体重、身高、腰围、皮褶厚度值（肱二头肌、肱三头肌、肩胛下肌和髌上肌）。脂肪量来源于生物阻抗；为所有肥胖标记物推导出最佳的身高标准化指数。种族出身是基于父母的自我报告。采用多水平模型获得经性别、年龄、月份、观察者和学校校正后的均值和种族差异（拟合为随机效应）。共有5887名9-10岁儿童参与（应答率68%），其中欧洲白人1345人，南亚儿童1523人，非洲-加勒比黑人1570人。结果与欧洲白人相比，南亚人的所有皮肤褶皱和脂肪质量百分比总和较高，体重指数（BMI）较低。南亚人略矮，但使用最佳高度标准化指数对这些比较没有实质性影响。在任何给定的脂肪量下，南亚人的身体质量指数都低于欧洲白人。在类似的比较中，非洲裔加勒比黑人的所有皮肤褶皱总数较低，但脂肪质量百分比较高，他们的体重指数也较高。非洲和加勒比裔黑人明显更高。使用最优高度标准化指数产生了显著不同的结果；皮肤褶皱指数总和显著降低，脂肪质量指数和体重身高比指数相似。在任何给定的脂肪量下，非洲-加勒比黑人和欧洲白人的BMI都是相似的。结论：与欧洲白人相比，英国南亚儿童的肥胖水平较高，非洲-加勒比黑人儿童的肥胖水平相似或较低。然而，基于BMI的比较并不能很好地代表这些差异，BMI系统地低估了南亚人的肥胖程度，而在非洲和加勒比黑人中，由于与身高有关，它高估了肥胖程度。
Background The objective of this study was to examine adiposity patterns in UK South Asian, black African Caribbean and white European children using a range of adiposity markers. A cross-sectional survey in London, Birmingham and Leicester primary schools was conducted. Weight, height, waist circumference, skinfold thickness values (biceps, triceps, subscapular and suprailiac) were measured. Fat mass was derived from bioimpedance; optimally height-standardized indices were derived for all adiposity markers. Ethnic origin was based on parental self-report. Multilevel models were used to obtain adjusted means and ethnic differences adjusted for gender, age, month, observer and school (fitted as a random effect). A total of 5887 children aged 9-10 years participated (response rate 68%), including 1345 white Europeans, 1523 South Asians and 1570 black African-Caribbeans.Results Compared with white Europeans, South Asians had a higher sum of all skinfolds and fat mass percentage, and their body mass index (BMI) was lower. South Asians were slightly shorter but use of optimally height-standardized indices did not materially affect these comparisons. At any given fat mass, BMI was lower in South Asians than white Europeans. In similar comparisons, black African-Caribbeans had a lower sum of all skinfolds but a higher fat mass percentage, and their BMI was higher. Black African-Caribbeans were markedly taller. Use of optimally height-standardized indices yielded markedly different findings; sum of skinfolds index was markedly lower, whereas fat mass index and weight-for-height index were similar. At any given fat mass, BMI was similar in black African-Caribbeans and white Europeans.Conclusions UK South Asian children have higher adiposity levels and black African-Caribbean's have similar or lower adiposity levels when compared with white Europeans. However, these differences are not well represented by comparisons based on BMI, which systematically underestimates adiposity in South Asians, and in black African-Caribbeans it overestimates adiposity because of its association with height.
