CONTEXT The time of life in which peak bone mass in the axial skeleton is attained has been the subject of considerable controversy, with estimates ranging from the time of sexual and skeletal maturity to the fifth decade of life. OBJECTIVE The objective was to examine whether dual energy x-ray absorptiometry (DXA) and computed tomography (CT) values for bone mass and bone density (BD) in the...

background: osteoporosis (op) is a common complication of inflammatory arthritis such as rheumatoid arthritis (ra). in this study we evaluated osteoporosis and its related factors in ra patients. methods: this cross - sectional study was carried out from 2010 to 2011 on 121 women with ra aged 45-75 years. these patients were selected and divided in two groups according to their bone mineral den...

background: low bone mass is a major health problem in postmenopausal women.there is no general agreement regarding relationship between serum level of lipidsand bone mineral density.objective: this study was carried out to investigate the association between lipidprofile and bone mineral density (bmd) in postmenopausal women in yazd, iran.materials and methods: this cross-sectional study was p...

bone disorders have emerged as a worrisome complication in hiv-infected patients in recent years. it is not clear that hiv infection itself or antiretroviral treatment or both are causes of bone loss. however, most studies have found a high prevalence of osteopenia and osteoporosis in hiv/aids patients. the objectives of this study were to determine the prevalence of osteopenia and osteoporosis...

patients and methods in this cross-sectional study, we evaluated all patients referred to a single rheumatology clinic for bone mineral density measurements from 2009 to 2010. all patients who had bone mineral density measurements taken from the hip, lumbar spine, forearm, and whole body were enrolled in the study. standard bone mineral density measurements were performed using a dual energy x-...

This study purposed to investigate the relationship between physical activity level and bone mineral density (BMD) in the elderly of Amirkola in northern Iran. This cross-sectional study was part of a proposal to assess the situation of the elderly in Amirkola (AHAP) (Amirkola Health and Ageing Project) conducted on 1113 elderly individuals (616 males and 497 females) in Amirkola city. Physic...

To determine the timing of peak bone mass and density, we conducted a cross-sectional study of bone mass measurements in 265 premenopausal Caucasian females, aged 8-50 yr. Bone mass and bone mineral density were measured using dual X-ray absorptiometry and single-photon absorptiometry at the spine (anteroposterior, lateral), proximal femur, radius shaft, distal forearm, and the whole body. Bone...
