Background: International Obesity Task Force proposed lower body mass index (BMI) cut-off values for defining overweight and obesity in Asian population. However, there is an absence of unanimity regarding the definition of overweight and obesity that is confusing while estimating disease burden, resource allocation, and priority setting. Therefore, the primary aim of the study was to assess the prevalence of overweight and obesity and its predictors as per different criteria (WHO criteria, Modified Asian criteria of BMI classification and BF% estimation by bioelectric impedance analysis technique). The secondary aim was to assess the concordance of overweight and obesity as diagnosed using these three methods. Methodology: A community-based cross-sectional study was conducted in a rural area of Rohtak, north India over a period of 1 year with a sample size of 1080. Anthropometric measurements including height, weight, blood pressure, body fat % analysis were recorded using standard protocols. Results: The prevalence of overweight and obesity were observed to be 49.62% (N = 536) as per the modified criteria for the Asian Indians (BMI ≥23 kg/m2) and 34.62% (N = 374) according to WHO criteria (BMI ≥25 kg/m2). A total of 18.3% of the study population were hypertensive. Modified criteria of BMI classification for Asian Indians had high sensitivity (67%) as compared to WHO criteria (55%) in predicting, diagnosing hypertension, and resembled sensitivity estimate obtained through direct body fat percentage estimation (69%). Conclusion: Modified criteria of overweight and obesity classification are better in terms of reducing comorbid dysmetabolic conditions, as exemplified by hypertension.
