Abstract

Objective To investigate the effect of the contents of body fat mass and lean mass on bone mineral density(BMD) in healthy women.Methods Four hundred and fourteen premenopausal women and 1020 postmenopausal women were enrolled in this study.BMDs of the lumbar spine,the left proximal femur,and whole bones were measured using a dual-energy X-ray absorptiometry(DEXA).Fat mass and lean mass were also determined.Results ①Fat mass and lean mass were significantly negative-correlated in all sites.② Lean mass was a significant determinant of BMDs of the lumbar spine,the left proximal femur,and whole bones in premenopausal women.③Fat mass contributed most to BMD in postmenopausal women.Conclusion Fat mass and lean mass have different roles in BMD.
