Abstract
The objective of this study was to determine the accuracy of waist to hip ratio (WHR) measured by a bioelectric impedance analysis (BIA) device for 9965 participants in a cohort study. Waist and hip circumferences were measured manually using a nonstretched, flexible tape, and WHR was calculated. Waist circumference was measured at the level of the iliac crest 3 times, and the average of 3 measurements was recorded. Body composition analysis was also done with the BIA device, and comparisons were made between the 2 techniques. There was a weak correlation for WHR compared using the manual method and BIA (r = 0.036). Also, there was a significant difference between the 2 measurement methods (P < .001).
