Introduction: Current Canadian clinical practice guidelines recommend the FRAX or Canadian Association of Radiologists and Osteoporosis Canada (CAROC) fracture risk assessment tools to report 10-year fracture risk in an individual. CAROC considers sex, age, BMD and previous fracture as risk factors. It is unknown whether one reporting system is more effective in helping general practitioners (GPs) identify individuals who should be recommended for pharmacological treatment. We...

Introduction: Cardiovascular disease and osteoporosis have often been reported to coexist in older people. However, the literature is conflicting regarding size and indeed direction of the association. The aim of the present study was therefore to assess associations between the Framingham general cardiovascular risk score and bone characteristics in a cohort of older adults.Methods: We studied 374 men and 379 women, born 1931–1939, who participated...

Objective: Total body less head (TBLH) and spine are the recommended DXA sites for bone health assessment in children and adolescents. However, inter-machine differences will affect use and interpretation of results in clinical care and research applications. We examined BMC and areal-BMD (aBMD) at 4 skeletal sites among healthy children to identify the magnitude of inter-machine differences in Z-scores.Methods: BMDCS evaluated healthy participa...

Objectives: The ketogenic diet (KD) is a medically supervised, high fat, low carbohydrate and restricted protein diet which has been used successfully in patients with refractory epilepsy. Only one published report has explored its effect on the skeleton. We postulated that KD impairs bone mass accrual and examined skeletal health parameters in this patient group.Methods: Patients commenced on the KD from 2002–2009 were enrolled in a prospective, lo...

Objective: Although metabolic syndrome is common in gout patients, recent reports that bone mineral density may actually be reduced (and falls common) in this group have led researchers to hypothesise that osteoporotic fracture may be more common in subjects with gout than in healthy controls. We tested this hypothesis in a national Danish registry.Material and Methods: We identified subjects as new users of allopurinol, a proxy for gout, for the years 1...

Sports specific training may have different impact on bone outcomes, and adolescence is a key period to optimize bone health. The aim was to examine hip differences on bone outcomes between osteogenic (football) and non-osteogenic (swimming and cycling) sports in adolescent males.One hundred twenty one males (13.1±0.1 years) volunteered to partake in this study that received ethics approval from the UK National Research Ethics Service. Participants ...

Objectives: Maternal vitamin D status in pregnancy is associated with neonatal bone mass, and altered DNA methylation. Mice exposed to early life vitamin D deficiency have lower bone mass and reduced bone accrual in response to mechanical loading. Using tibias from these mice we assessed DNA methylation of promoters of genetic loci important for bone growth and development.Methods: C57/BL6 mice received a vitamin D replete or deplete diet for 6 weeks per...

Objectives: Low birthweight has been shown to be associated with poorer musculoskeletal health in later life in a variety of epidemiological studies. We investigated relationships between birthweight, and grip strength or magnetic resonance imaging (MRI) measures of muscle volume in UK Biobank.Methods: UK Biobank is a large prospective cohort of men and women aged 40–69 years, including a detailed baseline assessment in which birthweight was collect...

Objectives: To examine the usefulness of Lego® as a visual reinforcer to explain genetic mutations to parents and carers of children and young people who have osteogenesis imperfecta (OI).Methods: Before entering a dedicated OI clinic, patients and carers completed a quantitative questionnaire devised by one of the team (MR), asking how much they knew about the genetic mutations causing OI within their families and whether they wished for a more det...

Introduction: Fracture risk is greater for adults with type 2 diabetes (T2D), despite normal or higher areal bone mineral density (aBMD) compared to controls. Tissue mineral density (TMD), measured by microCT, is more representative of actual mineral density than in vivo aBMD. The aim of this study was to determine whether TMD is greater in adults with T2D, and to investigate the correlates of TMD in adults with T2D.Methods: Using proximal femur...
