Ghachem A, Marcotte-Chénard A, Tremblay D, et al. - Researchers aimed at demonstrating the respective ability of BMI, waist circumference (WC), and relative fat mass index (RFM), to appraise body fat (BF%) estimated by DXA (DXA-BF%) and precisely pick out postmenopausal women living with obesity (BF% > 35). In addition, they investigated the best indicator of successful weight-loss intervention in postmenopausal women living with obesity. From five weight-loss studies, they retrieved a total of 277 women (age: 59.8 ± 5.3 y; BF%: 43.4 ± 5.3) with complete data for anthropometric measurements [BMI = weight/height (kg/m²); WC (cm)] and BF%. BMI was identified to be the best anthropometric index relative to RFM and WC, for measuring DXA-BF% and correctly recognizing postmenopausal women living with obesity, with lower misclassification error, before weight-loss intervention. Following weight-loss, the change in BMI was noted to be strongly linked with change in DXA-BF%, suggesting that the BMI is the best indicator of success of weight-loss intervention.
