PE11.1-2 | Childhood Obesity Risk and Prevention — Summary & Reflection

KEY TAKEAWAYS

Childhood obesity is a chronic, multi-system disease with epidemic prevalence in urban India. BMI-for-age is the screening standard: ≥85th percentile = overweight; ≥95th percentile = obese (IAP/WHO). Primary obesity (>95% of cases) arises from a sustained positive energy balance in a genetically susceptible child; secondary causes (hypothyroidism, Cushing syndrome, Prader-Willi) must be excluded in children with short stature, rapid onset, or dysmorphism — the 'tall obese child' vs 'short obese child' rule is the key clinical discriminator. Acanthosis nigricans is the cardinal cutaneous marker of insulin resistance and mandates metabolic screening. Comorbidities — insulin resistance/T2DM, dyslipidaemia, NAFLD, OSA, hypertension, Blount's disease — begin in childhood and must be actively sought. Prevention uses a risk-stratified approach (primary/secondary/tertiary); management is family-centred and begins with sustained lifestyle modification. Pharmacotherapy (orlistat ≥12 yr; metformin off-label for insulin resistance) is reserved for adolescents with severe obesity failing lifestyle modification. South Asian children have higher metabolic risk at a given BMI — waist circumference adds essential information beyond BMI alone.

REFLECT

Think about the last time you saw an overweight child in a health setting — or a family member, or someone from your community. Was obesity discussed as a health issue, or normalised as 'healthy eating'? How would you approach the conversation with a parent who does not perceive their child's weight as a problem? Reflecting on Kolb's experiential learning cycle: what concrete experience of obesity management would you seek out during your clinical postings, and how would you translate an abstract concept like 'family-centred counselling' into an actual consultation skill you can practice?
