Background: Previous studies suggested that the early identification of risk factors for the development of osteoporosis should reduce medical complications, which are associated with increased morbidity and mortality in older women.

Purpose: The present study had the objective to identify the relationship between Bone Mineral Density (BMD), anthropometric characteristics, years of post-menopause, strength, muscle mass and the performance on functional tests in up 10 years postmenopausal women.

Methods: Participated of the study fifty-eight post menopause women who were assessed by dual-energy X-ray absorptiometry (DXA) of femoral neck and whole-body to determine BMD and relative skeletal muscle index (RSMI). Also, the muscle strength was assessed by handgrip strength test (HGS) and two functional tests were performed: Timed Up-and-Go (TUG) and Five-Times-Sit-To-Stand (FTSTS).

Results: The results shown a positive correlation between BMD and weight (r = 0.54, p < 0.05), BMD and BMI (r = 0.56, p < 0.05), BMD and RSMI (r = 0.38, p < 0.05).

Conclusions: The findings of the present study demonstrated a correlation between muscle mass and BMD and also shown that anthropometric characteristics, such as higher weight and BMI were correlated with higher BMD and muscle mass in up 10 years postmenopausal women.
