Better Anthropometric Indicators to Predict Elevated Blood Pressure in North Indian Punjabi Adolescents

Sandeep Kaur Brar and Badaruddoza
Punjabi population as an ethnic group is at high risk for obesity and hypertension. It is believed that these disorders begin in childhood especially in adolescent period. However, no such comprehensive study is available regarding the reference cut-off point for the different anthropometric indicators. Hence, the aim of the present study was to determine the better anthropometric predictor for detecting hypertension in North Indian Punjabi Adolescents. A cross-sectional study with a sample of 1225 (634 boys and 591 girls) adolescents aged 10 to 18 years was carried out. The study considered three anthropometric indicators such as Body Mass Index (BMI), waist circumference and waist to height ratio (WHtR). Sensitivity, specificity, likelihood ratio and odds ratios analysis were used to identify better predictor for detecting hypertension. The sensitivities with confidence interval were in boys BMI: 0.754 (0.633-0.846); waist circumference: 0.766 (0.616-0.872); WHtR: 0.640 (0.520-0.745) and for girls BMI: 0.581 (0.422-0.726); waist circumference: 0.656 (0.468-0.808); WHtR: 0.621 (0.424-0.787). The odds ratios were in boys BMI: 4.26 (2.40-7.55); waist circumference: 4.35 (2.17-8.71); WHtR: 2.36 (1.43-3.89) and for girls BMI: 2.17 (1.15-4.06); waist circumference: 2.98 (1.41-6.32); WHtR: 2.52 (1.17-5.44). The study suggests waist circumference is the better predictor to predict cardiovascular risk factors in adolescent boys as compared to girls and provide a baseline for further study.
