Abstract
To compare the predictive value of the IAP and WHO criteria in identifying obesity complications in Indian children and adolescents. Blood pressure and body mass index was measured in 4434 children and adolescents [2539 boys; mean age 11.9 (3.0), 5.1-18 y] from affluent schools. The predictive accuracy of IAP 2015 and WHO BMI criteria in identifying hypertension was assessed. IAP 2015 BMI criteria labelled 203 more children obese than the WHO reference (649 as against 446). Hypertension was present in 75 (37%) of these. The difference in the prevalence of hypertension in subjects obese as per IAP 2015 criteria and their nonobese counterparts (50.2% as against 10.8%, p < 0.0001) was greater than that between subjects obese only by IAP 2015 or by both the criteria (36.9% as against 56.3%, p < 0.0001). The difference in the proportion of subjects with hypertension between two consecutive IAP 2015 BMI SDS category was highest for + 1.5 in boys (32.3% as against 49.8%, p < 0.0001) and + 2 in girls (25.9% as against 59.3%, p < 0.00012). IAP BMI criteria better predict hypertension in Indian children than WHO cutoffs and should be used in clinical practice to predict obesity complications.
