Comparison of Nutrition Status as Assessed by Revised IAP 2015 Growth Charts and CDC 2000 Growth Charts in Lower Socioeconomic Class School Children
This retrospective study was done to compare the nutrition status as assessed by the Revised IAP 2015 and CDC 2000 growth charts in 4011 school children from the lower socioeconomic class, 5 to 16 y of age in Chennai, Tamil Nadu. The anthropometric measurements taken as per standard guidelines were retrieved from the school health records. The data were converted to Z scores and agreement between the two charts was assessed by kappa coefficient using SPSS version 16. The prevalence of overweight/obesity, thinness and stunting was 12.2%, 9.8% and 9% respectively with IAP 2015 charts. The corresponding values are 7.3%, 41.7% and 23% respectively with CDC 2000 charts. Minimal agreement was found for body mass index (BMI) for age (kappa 0.314) and weak agreement for height for age (kappa 0.497). Revised IAP 2015 growth charts diagnose more Indian children with overweight and obesity than CDC 2000 growth charts. The CDC growth chart diagnoses more stunting and thinness.
