Osteoporosis and obesity are two public health problems that are growing in prevalence around the world. These disorders, which appear to be unrelated, share several characteristics at the molecular and clinical levels, and at the predisposing risk factors. Body mass (BM) is composed of three compartments: total lean mass, which includes muscle mass (MM), fat mass (FM) and bone mass. Several studies suggest that BM is positively correlated with bone mineral density (BMD), indicating the beneficial effect of FM. Others instead argue that MM has a greater positive effect on BMD. On the basis of current knowledge, it is unclear whether FM or MM has the greatest effect on BMD. Objective: To study the effect of FM and MM on BMD in postmenopausal women. Materials and Methods: Observational, descriptive and transversal study. Intentional sampling by spontaneous demand. A bioelectrical impedance analysis was performed using the In-Body (720) body composition analyzer. Linear regression was performed between BMD, MM and FM. StatGraphics statistical software was used. Results: The sample was represented by 52 postmenopausal women aged 60 ± 5 years belonging to the university community (UNSa). There was a strong correlation between MM and BMD (p
