Does bone density, bone strength, sarcopenia or dynapenia explain greater risk of fracture in obesity?

Evans Amy , Eastell Richard , Walsh Jennifer

Obesity is associated with greater risk of proximal humerus and ankle fracture, despite greater areal BMD (aBMD). We aimed to investigate whether greater risk of some fractures in obesity was due to skeletal or non-skeletal determinants. 100 individually-matched pairs of normal weight (NW) (18.5–24.9 kg/m2) and obese (OB) (BMI >30 kg/m2) individuals, aged 25–40 and 55–75 years underwent DXA to determine hip and lumbar spine aBMD, whole ...

Bone mineral density and vascular calcification in obesity

Bouquegneau Antoine , Walsh Jennifer , Evans Amy , Paggiosi Margaret , Eastell Richard

Background: The presence of vascular calcification (VC) is a predictive factor for the development of cardiovascular diseases, especially in the obese population. VC has also been inversely associated with bone mineral density (BMD) but the results have been inconsistent. The main aim of this study was to evaluate the associations between VC, obesity and volumetric BMD (vBMD).Methods: We studied 148 healthy men and women, aged 55–75 years, divided i...

Vitamin D is low in obesity, and this is due to greater volume of distribution

Low circulating levels of total 25-hydroxyvitamin D (25OHD) have been reported in obese people of different ethnicities in several countries. Low total 25OHD in obesity could be due to lower binding proteins (with normal free 25OHD), lower dietary intake or sunlight exposure, greater volume of distribution (pool size) or more rapid metabolic clearance.The aims of this study were to determine if free 25OHD and 1,25-dihydroxyvitamin D (1,25(OH)2...
