Body mass index (BMI) is a useful tool to assess nutritional status and may be applied to study undernutrition and overweight/obesity in distinct ethnic populations like Khasi tribal children to derive cross sectional reference values for undernutrition, overweight and obesity. Cross-sectional methods of anthropometric measurements in 957 Khasi children (467 boys, 490 girls) of age 11 to 17 years were used to derive BMI (kg/m2), which were compared with national and international standards. Smoothed Khasi specific BMI percentiles were generated by the LMS method and International Obesity Task Force (IOTF) criteria were applied as for Asian children. Mean BMI in Khasi children were below those of national and international reference standards. Girls achieved higher BMI in late adolescence, but boys remained thin throughout. Smoothed percentile charts were constructed for boys and girls and IOTF criteria for undernutrition, overweight and obesity were applied corresponding to 11, 77.4 and 90.5 percentiles for boys and 13.4, 74 and 91.2 percentiles for girls, respectively. Undernutrition was more prevalent in boys than in girls, particularly at age 14 and 15 years (p < 0.001). There was a small prevalence of obesity, 5.1% in boys and 9.5% in girls at age 17 years. BMI values in pubertal Khasi boys and girls are different from commonly used standards. BMI percentiles specific to Khasi children in puberty are advocated to track changing trends over time.
体重指数（BMI）是评估营养状况的一个有用工具，可用于研究像卡西部落儿童这样不同种族人群中的营养不良以及超重/肥胖情况，以得出关于营养不良、超重和肥胖的横断面参考值。采用横断面方法对957名11至17岁的卡西儿童（467名男孩，490名女孩）进行人体测量，以得出BMI（千克/平方米），并将其与国内和国际标准进行比较。通过LMS方法生成了卡西族特有的平滑BMI百分位数，并按照针对亚洲儿童的国际肥胖特别工作组（IOTF）标准进行应用。卡西儿童的平均BMI低于国内和国际参考标准。女孩在青春期后期的BMI较高，但男孩在整个青春期都较瘦。为男孩和女孩绘制了平滑百分位图，并分别对应于男孩的第11、77.4和90.5百分位数以及女孩的第13.4、74和91.2百分位数应用IOTF关于营养不良、超重和肥胖的标准。男孩中的营养不良比女孩更普遍，尤其是在14岁和15岁时（p<0.001）。肥胖的患病率较低，17岁时男孩为5.1%，女孩为9.5%。青春期卡西族男孩和女孩的BMI值与常用标准不同。提倡使用卡西族青春期儿童特有的BMI百分位数来跟踪随时间变化的趋势。
