BMI Cutoffs for Obesity in India
BMI Classification for Indian Population
- The World Health Organization defines obesity as BMI ≥30 kg/m², but for South and Southeast Asian countries including India, overweight is defined as BMI ≥23 kg/m² and obesity at lower thresholds than Western populations 2
- Several studies have demonstrated that BMI cut points between 23 and 27 kg/m² more accurately identify obesity in Asian populations, including Indians 1, 4
- The standard World Health Organization BMI classifications are not appropriate for the Indian population 3
Rationale for Lower BMI Cutoffs
- Asian populations, including Indians, have greater adiposity and higher comorbidity risks at lower BMI levels compared to Western populations 1, 4, 5
- Studies show that cardiometabolic diseases occur at lower BMI levels in Asian populations, necessitating lower thresholds for clinical intervention 3
Additional Measurements for Risk Assessment
- Waist circumference should be used alongside BMI for more accurate risk assessment in Indians, with cutoffs of ≥80 cm for women and ≥90 cm for men to identify abdominal obesity 2
- Waist-to-height ratio ≥0.5 can be used to identify individuals at risk of obesity-related metabolic abnormalities 2
Clinical Implications
- Healthcare providers should recognize and treat obesity as a chronic, progressive, relapsing disease 2
- For Indians approaching but not meeting BMI-based criteria for overweight or obesity, clinicians should assess for obesity-related complications to clarify long-term health risks 2
- A comprehensive clinical assessment is recommended for individuals with BMI ≥23 kg/m² to identify obesity-related complications and potential barriers to treatment 2
