Most studies reporting prevalence of obesity use actual weight and height measurements. Self-reported have been used in epidemiological as they shown to be reliable, convenient, inexpensive alternatives However, the accuracy self-reported might vary different regions because difference health awareness social influences. This study aims determine reliability compared measured among adults Malaysia. was a cross-sectional conducted at community level during blood pressure screening campaigns. Participants their questionnaire survey. Their were validated using measurements by researchers on same setting. Body mass index (BMI) defined underweight (<18.5kg/m2), normal (18.5-22.9 kg/m2), overweight (23-27.4 kg/m2) (≥27.5 kg/m2). Bland-Altman analysis, intraclass correlation coefficients weighted Kappa statistics assess degree agreement between height. A total 2781 participants recruited this study. The mean 0.4 kg cm respectively. Weighted analysis showed that there substantial BMI classifications derived from measurement (ҡ = 0.920, p<0.001). There no marked sensitivity specificity Malaysian gender. We observed body within sample adults. While weaker with particularly for obese individuals, values accurate 88.53% participants. thus conclude measures may useful tracking estimating population trends amongst
