Timing of peak bone mass: discrepancies between CT and DXA.
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...
متن کاملBone densitometry in pediatric populations: discrepancies in the diagnosis of osteoporosis by DXA and CT.
OBJECTIVES To test the hypothesis that because of errors associated with growth and development, osteoporosis is frequently overdiagnosed in children when using dual-energy x-ray absorptiometry (DXA). This study compared bone density values obtained by DXA with those from computed tomography (CT), which is not influenced by body or skeletal size. STUDY DESIGN Vertebral bone density was measur...
متن کاملRelationship between body mass index and bone mineral density in HIV-infected patients referred for DXA
INTRODUCTION Reduced bone mass density (BMD) is a frequent observation in HIV-infected persons. Relationship between body mass index (BMI), weight, height and BMD was reported for many populations. In particular, BMI has been found to be inversely related to the risk of osteoporosis. METHODS This is a cross-sectional, monocentric study where all HIV-infected patients referred to first DXA sca...
متن کاملDelayed puberty and peak bone mass.
The accrual of bone mass during childhood and adolescence is a major determinant of peak bone mass (PBM), and thereby of the risk of osteoporotic fractures occurring in advanced age (1). The development of noninvasive techniques, such as dual-energy X-ray absorptiometry (DXA), has made it possible to determine with precision and very low radiation exposure the pattern of bone mineral mass accum...
متن کاملChildhood bone mass acquisition and peak bone mass may not be important determinants of bone mass in late adulthood.
During childhood and adolescence, bone mass acquisition occurs primarily through skeletal growth. It is widely assumed that bone mass acquisition throughout childhood is an important determinant of the risk of osteoporosis in late adulthood; bone mass is thought to resemble a bank account in which deposits persist indefinitely. However, several well-controlled clinical studies suggest that incr...
