Lean mass as a determinant of bone mineral density of proximal femur in postmenopausal women.

Objective: To verify which component of body composition (BC) has greater influence on postmenopausal women bone mineral density (BMD).

Subjects And Methods: Four hundred and thirty women undergoing treatment for osteoporosis and 513 untreated women, except for calcium and vitamin D. Multiple linear regression analysis was performed in order to correlated BMD at lumbar spine (LS), total femur (FT), femoral neck (FN) with body mass (BM), total lean mass (LM) and total fat mass (FM), all determined by DXA.
