Anorexia nervosa (AN) is a condition of severe low weight that is associated with low bone mass, impaired bone structure, and reduced bone strength, all of which contribute to increased fracture risk. Adolescents with AN have decreased rates of bone accrual compared with normal-weight controls, raising additional concerns of suboptimal peak bone mass and future bone health in this age group. Ch...
Osteoporosis is a systemic skeletal disease characterised by loss of bone mass and microarchitectural integrity that lead to increased bone fragility and risk of fracture.' Its natural history is one of slow, progressive bone loss that often remains asymptomatic and undiagnosed for many years. Only when a substantial amount of bone has been lost do the characteristic low trauma fractures occur....
In humans, low peak bone mass is a significant risk factor for osteoporosis. We report that LRP5, encoding the low-density lipoprotein receptor-related protein 5, affects bone mass accrual during growth. Mutations in LRP5 cause the autosomal recessive disorder osteoporosis-pseudoglioma syndrome (OPPG). We find that OPPG carriers have reduced bone mass when compared to age- and gender-matched co...
PURPOSE The present review critically evaluates existing literature on the effects of short- and long-term low energy availability (EA) on bone metabolism and health in physically active individuals. METHODS We reviewed the literature on the short-term effects of low EA on markers of bone metabolism and the long-term effects of low EA on outcomes relating to bone health (bone mass, microarchi...
osteoporosis, characterized by low bone mass and microarchitectural deterioration of bone tissue leading to enlarged bone fragility and a consequent increase in fracture risk is a leading cause of morbidity and mortality in elderly people. the mortality rate in elderly persons with hip fracture approaches 20%. half of them will be disabled in the remained life. iranian multicenter osteoporosis ...
Children with malignancies have low bone mass. Pathways for metabolic bone disease were investigated in children with cancer by concomitantly assessing lifestyle, clinical, and biochemical predictors of bone mass. Forty-one children who were receiving cancer therapy for 61 weeks and 39 controls were studied. Data on lifestyle factors, biochemical and hormonal parameters, dual-energy X-ray absor...
fracture. several chronic medical conditions, medications, and life style factors affect bone mineral accrual. this study aims to evaluate the bone mineral densities and hip axis lengths in the local population. materials and methods: 336 normal bangladeshi women age ranges 20 to 70 years had evaluation of their bone mineral densities (bmds) by means of dual x-ray absorptiometry (dxa). results:...
relative importance of lean and fat mass on bone mineral density in iranian children and adolescents
conclusions these findings suggest that lean mass was the most important predictor of bmd in both genders. physical activity appears to positively impact on lean mass and needs to be considered in physical education and health-enhancing programs in iranian school children. background body weight is made up of lean and fat mass and both are involved in growth and development. impression of these...
