Sarcopenia and osteoporosis are common in later life, often coexist, and increase the risk of adverse health outcomes such as disability, falls and fracture. Binkley and colleagues recently devised a score-based system for the diagnosis of ‘dysmobility syndrome’ in an attempt to combine adverse musculoskeletal phenotypes and indentify older individuals at particular risk. We applied these criteria to a larger cohort of participants from the Hertfordshire Cohort Study...

Purpose: To determine the association between socio-economic status (SES) and risk of hip fracture.Methods: Retrospective cohort study. We used a population database which contains primary care and hospital inpatient records of over >5 million people. Anyone registered in this database in 2009–2012 and resident in an urban area was eligible. Main measures: a validated SES composite index (accounting for proportion of unemployed, insufficiently e...

Purpose: To determine whether and which co-morbidities (amongst those included in the Charlson co-morbidity index) confer an increased risk of hip fracture amongst elderly men.Methods: We conducted a population-based cohort study using a population database which contains primary care and hospital inpatient records of over >2 million people. All men aged ≥65 years registered on 1/1/2007 were followed up until 31/12/2009. Both exposure (co-morbi...

Background: Improving the general population’s vitamin D status through food fortification is part of an ongoing debate. Vitamin D status during pregnancy may influence the long-term bone health of offspring; yet conflicting results have been reported and none of the studies have examined paediatric fracture as outcome.Method: The influence of extra vitamin D exposure during prenatal life and risk of fracture during adolescence was determined by com...

Background: Improving the general population’s vitamin D status through food fortification is part of an ongoing international debate.

Animal studies suggest that fetal movements are key to healthy skeletal development, but evidence in humans is limited. Breech presentation occurs in 3% of term births and is associated with reduced fetal movement and higher incidence of hip dysplasias, but more general effects on bone development have not been explored.Offspring whole body bone outcomes were measured using dual-energy X-ray absorptiometry (DXA) at mean(SD) 6(5) days after birth in 993 i...

Background: Preclinical model studies suggest early life vitamin D depletion reduces bone’s response to mechanical loading. The MAVIDOS trial (randomised placebo controlled trial of vitamin D supplementation in pregnancy) reported winter-born infants of mothers receiving vitamin D supplementation had higher bone mass; the earlier Southampton Princess Ann Cohort study linked pregnancy blood vitamin D levels to later bone mass and size. We showed previously that bone respon...

Objectives: Children who fracture have lower bone mineral density (BMD) measured by dual energy X-ray absorptiometry (DXA) than children who do not sustain fractures, but there is little data on bone microarchitecture in relation to childhood fracture. We assessed tibia microarchitecture using high resolution peripheral quantitative computed tomography (HR-pQCT) in children with recent fracture and those without a history of fracture.Methods: Children ag...

Objectives: Weight bearing physical activity (PA) is thought to be beneficial to bone mineral accrual in childhood, but the influence of PA and sedentary time on bone microarchitecture is less well described. We examined the relationships between self-reported PA and volumetric bone mineral density (vBMD) and bone microarchitecture at the distal tibia, assessed using high resolution peripheral quantitative computed tomography (HR-pQCT).Methods: Healthy c...
