Resumen

Introduction: Postmenopausal women have excess adiposity due to the lack of estrogens, which is related with an increase in the prevalence of metabolic syndrome (MS) factors. Two equations have been developed to measure body fat mass (FM) by bioimpedance (BIA) for Mexican women and none of the existing equations have been evaluated in Mexican postmenopausal women with MS. Material and methods: We describe the association and agreement between two different BIA equations: NHANES III and Macias et al to estimate FM in 86 women (42-72 years old). Anthropometric and body composition measurements (BIA) were done in all women; FM was measured by densitometry (DXA). Mean differences by age group (< 55 years old and > 55 years old) (Student T test), correlations, simple linear regression models and agreement analysis (Bland-Altman method) were done. Results: Both equations showed underestimation of %FM compared to DXA. The equation that presents the greatest correlation and agreement with the gold standard is the NHANES equation, in both age groups. Conclusions: The NHANES equation is valid to estimate FM in Mexican postmenopausal women with MS. We recommend the use of this equation in clinical practice.
