title: The influence of aging on the association between adiposity and bone mineral density in Jordanian postmenopausal women.
abstract: The objective of this study was to assess the relative association between body weight, body mass index (BMI), lean mass (LM) and fat mass (FM), and bone mineral density (BMD) in a group of Jordanian postmenopausal women and investigate if this possible association changes with age. A total of 3256 patients had dual-energy X-ray absorptiometry (DXA) scan in the period from January 2009 till January 2012 at the Radiology and Nuclear Medicine Department of Jordan University Hospital. Only 584 women met the selection criteria. Age has been recorded, and patients were divided into subgroups according to age. Body weight and height were measured, and BMI was calculated. Body composition (LM, FM, percentage of android fat, and percentage of gynoid fat) was assessed by DXA. BMD of the lumbar spine (L1-L4) and femoral neck was measured by DXA. Weight, BMI, FM, LM, percentage of android fat, and percentage of gynoid fat were positively correlated to BMD at both lumbar spine and femoral neck. However, this correlation disappeared at the age of 70 yr at lumbar spine and 75 yr at femoral neck. This study suggests that both FM and LM are important determinants of BMD in Jordanian postmenopausal women, and this correlation disappears after the age of 70 yr at lumbar spine and 75 yr at femoral neck.
