Abstract Objectives To ascertain the utility of the new pan Indian 2015 IAP references in rural South Indian children and the ability of new IAP charts to recognise children with abnormal cardiometabolic risk factors in 10 to 16 y age group. Methods Among school health camps conducted at two centres of Tamil Nadu– rural Vellore and rural Erode- height, weight, waist circumference, blood pressure, triceps skin-fold thickness and body fat percentage were measured by trained pediatricians and Z-scores calculated. The anthropometric measures were studied as per IAP 2015 references and compared to other national and international references. Their utility in identification of malnutrition and cardiometabolic risk ascertained. Results A total of 420 children (210 from Erode and 210 from Vellore) in the age group of 10 to 16 y were included in the study. New IAP references recognized more short stature (4.2 vs. 3%), wasting (11 vs. 1.5%) and overweight (14.2 vs. 13.2%) children compared to old IAP charts. The Z-scores of anthropometric measures as per New IAP 2015 references had significant correlation with old IAP and other international data (p < 0.05). It was noted that new IAP charts could detect 83.3%, old IAP chart 50% and WHO 83.3% of subjects with malnutrition. New IAP charts could detect 70.3% cardiometabolic risk associated with over nutrition compared to old IAP (57.4%) and WHO (51.8%). Conclusions There is a significant prevalence of both under nutrition and overweight in rural setting. IAP 2015 reference is useful to diagnose children with under nutrition and overweight including abnormal cardiometabolic risk. Keywords Pan Indian IAP 2015 growth reference . Cardio metabolic risk .

Introduction Growth is a barometer of well being in any given child. The Indian Academy of Pediatrics (IAP) came out with growth charts for Indian children constructed across India in 1993 by K N Agarwal. This was the first pan Indian references

useful for Indian children [1]. Subsequently, the World Health Organisation came out with WHO 2007 standards based on the Multicentre Growth Reference Study, which recommended paediatricians all over the world to use this chart for children less than 5 y [2]. For children more than 5 y, WHO recomme
