Aim: Human gut microbiota is an important determinant of health and disease. Discoveries from recent microbiome studies have been postulated as actionable targets to treat malnutrition, diabetes, obesity among other conditions. The role of the gut microbiome on the development of the human musculoskeletal system is yet to be established. The aim of our study was to investigate the association between bacterial operational taxonomic units (OTUs) of the gut in relation to bone m...

Objectives: Previous studies indicate that about half of boys and one fourth of girls suffer a fracture before the age of 16 years. Similarly, children of European descent are more prone to fracture. Here we aimed to investigate at the population level the influence of sex, ethnic background and bone mineral density (BMD) on the occurrence of bone fractures in children of school age.Methods: This study (n=3,633 children with complete information...

Background: Low total body BMD (TB-BMD) is an established risk factor for fractures in healthy children. However, bone strength depends not only on bone mass and density, but also on the structural geometry of bones. Hip structural analysis (HSA) is a technique applied on hip DXA scans to calculate several bone geometry parameters. The aim of our study was to evaluate other bone geometrical parameters that can constitute determinants of fracture risk. Specifically, we examined...

Aim: Lean and bone mass have considerably high phenotypic and genetic correlations with a shared heritability estimate ranging between 30 and 40% in adults. A genome-wide association study (GWAS) on total body lean mass and a bivariate GWAS on lean mass and BMD were ran in a cohort of children to identify genes with pleiotropic effects on muscle mass and peak bone mass attainment.Methods: Subjects are part of the Generation R study, a prospective multiet...

Background: The relation between sex hormone-binding globulin (SHBG) and vertebral fracture (VFx) is unclear.Aim: To examine whether SHBG is associated with bone mineral density at lumbar spine (LS-BMD), trabecular bone score (TBS) and prevalent VFx.Methods: Data of 6224 men and women participants in the third visit of the first cohort (I-3) and the first visit of the second cohort (II-1) of a prospective population based cohort, w...

Background: Fracture risk is increased in Type 2 diabetes (T2D) individuals. Bone mineral density (BMD) is inversely associated with fracture risk but paradoxically high in T2D individuals. Trabecular bone score (TBS) reflects bone microarchitecture and predicts fracture risk.Objective: We aimed to compare mean lumbar spine TBS (LS-TBS) and lumbar spine BMD (LS-BMD) values, across individuals with and without i) vertebral fracture (VFx), ii) T2D; and iii...

Introduction: Due to the ‘greying’ of (industrialized) societies the incidence of osteoporosis and fragility fractures is expected to be increasing. Our aim was to investigate in an elderly population if the incidence of non-vertebral fractures (overall and site specific) has changed after a longer follow-up, and its relation with osteoporosis or osteopenia assessed by bone mineral density (BMD) at baseline.Methods: Incident non-vertebral fract...

Objectives: Advanced or delayed physiological age may influence significantly health and disease processes. Physiological age can be estimated using several parameters including dental age (DA). Previous meta-analyses studying “Number of Teeth at 15 Months” (NT15M) and “Age at First Teeth Eruption” (AFTE) have identified 15 loci. We performed a genome-wide association study (GWAS) meta-analysis to identi...

The close relationship between muscle and bone has long been recognized especially during development where one tissue does not develop in the absence of the other. The mechanical interactions between the two tissues have dominated research under the assumption that the major interaction between the two tissues was the loading/unloading of bone by muscle. Though clear that loading of bone by muscle is necessary to maintain healthy bone, the concept that bone could have positiv...
