## Diabetes Prevalence in India: Epidemiological Overview **Key Point:** Recent large-scale surveys (ICMR-INDIAB, NDSP) estimate the prevalence of diabetes in urban India at approximately 10–15%, with significant variation by region and socioeconomic status. ### Prevalence Patterns in India | Setting | Prevalence Range | Notes | |---------|------------------|-------| | Urban areas | 10–15% | Higher due to lifestyle, obesity, sedentary behavior | | Rural areas | 3–5% | Lower; increasing trend | | Metropolitan cities | 15–20% | Highest in metros like Delhi, Mumbai, Bangalore | | Overall national | 7–8% | Weighted average across rural and urban | **High-Yield:** The ICMR-INDIAB study (2015–2019) found a prevalence of 11.4% in urban areas and 3.5% in rural areas. This urban-rural divide is a critical epidemiological feature of diabetes in India and is frequently tested in NEET PG. **Clinical Pearl:** The prevalence is rising rapidly in India, with an estimated 77 million people with diabetes (2019), projected to reach 134 million by 2045. This makes India the "diabetes capital" of the world. ### Factors Driving Urban Prevalence - Rapid urbanization and lifestyle changes - Increased obesity and sedentary behavior - Dietary transition (high refined carbohydrates, processed foods) - Genetic predisposition in South Asian populations - Better case detection and awareness in urban areas
