Pediatric BMI Percentile (IAP 2015)
Calculate child / adolescent BMI and classify per Indian Academy of Pediatrics 2015 cut-offs — purpose-built for Indian children, more accurate than CDC/WHO charts.
Childhood obesity, one tap away
EasyClinic auto-screens for childhood obesity at every visit, prompts metabolic workup at overweight cut-off, and books WhatsApp diet-follow-up at 4 weeks — built for Indian paediatric practice.

Why use IAP 2015 cut-offs over WHO/CDC?
The IAP 2015 BMI charts (Khadilkar et al.) were derived from contemporary affluent Indian urban children and use the adult equivalent of 23 kg/m² as overweight and 27 kg/m² as obesity — reflecting the lower BMI at which South Asians develop metabolic disease. CDC and WHO charts often miss early metabolic risk in Indian children.
Indian childhood obesity epidemic
- Urban Indian children: 22-29% overweight/obesity (CNNS 2019).
- Rural prevalence rising sharply (~7-10%) post-pandemic.
- Children with BMI ≥ 95th percentile have 4× risk of adult type 2 diabetes.
- NAFLD prevalence in obese Indian children: 35-50%.
What to do for an overweight child
- Family-based intervention — never target the child alone.
- Diet: reduce sweetened beverages, ultra-processed foods, fried snacks (samosas, kachoris). Add fruit, vegetables, whole grains, dal.
- Activity: ≥ 60 min moderate-vigorous activity daily. Limit screen time to < 2 h.
- Sleep: 9-12 hours (school age), 8-10 hours (adolescent).
- Metabolic screen (annually if BMI ≥ overweight): fasting glucose, HbA1c, lipid profile, LFT, TSH.
- BP at every visit using pediatric percentile.
Frequently Asked Questions
▸Why not use WHO BMI-for-age Z-scores?
WHO Z-scores are valid worldwide but underestimate metabolic risk in South Asian children. IAP 2015 charts are India-specific and the IAP recommends them for all Indian children aged 5-18 years. For children < 5 years, WHO Z-scores remain standard.
▸When should I do an OGTT in an obese child?
Per IAP & ISPAD guidelines — when BMI ≥ 95th percentile + any of: family h/o T2DM, acanthosis nigricans, hypertension, dyslipidaemia, PCOS, or HbA1c ≥ 5.7%. Cost of OGTT in India: ₹400-1,000.
▸Should we counsel weight loss in an overweight child?
For mild overweight, the goal is weight maintenance — children grow into a normal BMI. For obesity, modest weight loss (0.5 kg/month) is appropriate with structured intervention. Aggressive dieting can impair growth and trigger eating disorders.
▸What is the role of bariatric surgery in Indian adolescents?
AIIMS and a few centres (Apollo, Asian Bariatrics) offer adolescent bariatric surgery for BMI ≥ 40 (or ≥ 35 with major comorbidity) failing lifestyle intervention. Cost ₹3-6 lakh; insurance variable. Strict multi-disciplinary criteria apply.
▸Are GLP-1 agonists approved for Indian children?
Liraglutide and semaglutide are approved by DCGI for adolescent obesity (≥ 12 yr, BMI ≥ 95th percentile) when lifestyle measures fail. Costs ₹8,000-15,000/month — significant barrier. IAP recommends use only by paediatric endocrinologists.
