Bone Abstracts

Juvenile idiopathic arthritis (JIA) is associated with low bone mass, poor bone strength, and an increased fracture risk. Children with JIA enter adulthood with suboptimal bone mass. In children with JIA, fracturing of the 2nd metatarsal is common due to poor bone strength. Currently no gold standard measure exists for bone quality in the foot. A reproducible protocol is required to assess key bone outcomes at the 2nd metatarsal using pQCT.Objective: To ...

Objective: This work investigated the changes of bone hip structural parameters in obese adolescents enrolled in a successful weight loss program.Methods: Thirty-one obese adolescents (age 13.61±1.27) enrolled in a 8-month weight loss program combining physical activity and nutrition were compared with normal-weight (NW) matched peers (age 15.9±0.43). Investigations were performed at baseline and 8 months. Bone geometric and strength indices we...

Objectives: Cross-sectional studies show that exercise may have positive effects on bone outcomes in youth. However, there is no evidence from longitudinal studies, which type of sports can induce improvements in bone acquisition in adolescent athletes. Therefore, this study aimed to investigate the longitudinal differences in bone acquisition and bone metabolism between adolescent males participating in osteogenic (football) and non-osteogenic (swimming, cycling) sports compa...
