Bone Abstracts

Differences in fracture rates and bone mass in families and individuals of different ethnic origins may be due to differing lifestyles and/or genetic backgrounds. This study aimed to assess the associations of bone mass and fracture prevalence in adolescents with maternal bone mass and fracture history, and sibling fracture history.Data from 1389 adolescent-biological mother pairs from the Birth to Twenty (Bt20) longitudinal study were obtained. Question...

Bone accrual and the attainment of peak bone mass influence an individual’s predisposition to fracture or osteoporosis later in life. The developmental tempo and the movement of the periosteal and endosteal surfaces of the appendicular skeleton during growth result in variations in bone mineral content and density. During puberty the differential in peak height and peak bone mass accretion negatively influence bone strength. A surrogate measure of bone strength is the met...

The prevalence of fractures in white children in South Africa is double that of black children (1). White males who fractured were shown to be more physically (2). The aim of this study was to compare the bone mass and geometry measures using peripheral quantitative computed tomography (pQCT) and dual energy x-ray absorptiometry (DXA) in black and white children with and without a history of fracture to determine the risk factors for fractures.Lifetime f...
