Increased Bone Material Strength Index Is Positively Associated With the Risk of Incident Osteoporotic Fractures in Older Swedish Women.

No previous studies have investigated the association between the bone material strength index (BMSi; an indicator of bone material properties obtained by microindentation) and the risk of incident fracture. The primary purpose of this prospective cohort study was to evaluate if BMSi is associated with incident osteoporotic fracture in older women and, secondarily, with prevalent fractures, anthropometric traits, or measurements of bone mineral density (BMD) by dual-energy X-ray absorptiometry (DXA). In a population-based cohort, 647 women aged 75 to 80 years underwent bone microindentation using the OsteoProbe device.

The Prevalence of Vertebral Fractures Is Associated With Reduced Hip Bone Density and Inferior Peripheral Appendicular Volumetric Bone Density and Structure in Older Women.

Vertebral fractures (VFs) are among the most severe and prevalent osteoporotic fractures. Their association with bone microstructure have been investigated in several retrospective case-control studies with spine radiography for diagnosis of VF. The aim of this population-based cross-sectional study of 1027 women aged 75 to 80 years was to investigate if prevalent VF, identified by vertebral fracture assessment (VFA) by dual-energy X-ray absorptiometry (DXA), was associated with appendicular volumetric bone density, structure, and bone material strength index (BMSi), independently of hip areal bone mineral density (aBMD).

Type 2 Diabetes Mellitus Is Associated With Better Bone Microarchitecture But Lower Bone Material Strength and Poorer Physical Function in Elderly Women: A Population-Based Study.

Type 2 diabetes mellitus (T2DM) is associated with an increased risk of fractures according to several studies. The underlying mechanisms remain unclear, although small case-control studies indicate poor quality of the cortical bone. We have studied a population-based sample of women aged 75 to 80 years in Gothenburg, randomly invited from the population register.

A High Amount of Local Adipose Tissue Is Associated With High Cortical Porosity and Low Bone Material Strength in Older Women.

Obesity is associated with increased risk of fractures, especially at skeletal sites with a large proportion of cortical bone, such as the humerus and ankle. Obesity increases fracture risk independently of BMD, indicating that increased adipose tissue could have negative effects on bone quality. Microindentation assesses bone material strength index (BMSi) in vivo in humans.

Bone turnover markers predict bone mass development in young adult men: a five-year longitudinal study.

Context: Peak bone mass is an important factor for the lifetime risk of developing osteoporosis. Ways to predict bone development in young adulthood are lacking. Objective and Main Outcome Measures: The aim of this study was to investigate whether baseline measurements of bone turnover markers could predict bone development in early adulthood in men.

X-ray-verified fractures are associated with finite element analysis-derived bone strength and trabecular microstructure in young adult men.

It has been suggested that fracture during childhood could be a predictor of low peak bone mass and thereby a potential risk factor for osteoporosis and fragility fractures later in life. The aim of this cross-sectional, population-based study was to investigate whether prevalent fractures, occurring from birth to young adulthood, were related to high-resolution peripheral quantitative computed tomography (HR-pQCT)-derived trabecular and cortical microstructure, as well as bone strength estimated by finite element (FEA) analysis of the radius and tibia in 833 young adult men around the time of peak bone mass (ages 23 to 25 years). In total, 292 subjects with prevalent X-ray-verified fractures were found.

Catch up in bone acquisition in young adult men with late normal puberty.

The aim of this study was to investigate the development of bone mineral density (BMD) and bone mineral content (BMC) in relation to peak height velocity (PHV), and to investigate whether late normal puberty was associated with remaining low BMD and BMC in early adulthood in men. In total, 501 men (mean ± SD, 18.9 ± 0.

Smoking is associated with impaired bone mass development in young adult men: a 5-year longitudinal study.

It has previously been shown that smoking is associated with reduced bone mass and increased fracture risk, but no longitudinal studies have been published investigating altered smoking behavior at the time of bone mass acquisition. The aim of this study was to investigate the development of bone density and geometry according to alterations in smoking behavior in a 5-year, longitudinal, population-based study of 833 young men, age 18 to 20 years (baseline). Furthermore, we aimed to examine the cross-sectional, associations between current smoking and parameters of trabecular microarchitecture of the radius and tibia, using high-resolution peripheral quantitative computed tomography (HR-pQCT), in young men aged 23 to 25 years (5-year follow-up).

Cortical consolidation due to increased mineralization and endosteal contraction in young adult men: a five-year longitudinal study.

Context: Peak bone mass is an important factor in the lifetime risk of developing osteoporosis. Large, longitudinal studies investigating the age of attainment of site-specific peak bone mass are lacking. OBJECTIVE AND MAIN OUTCOME MEASURES: The main outcome measures were to determine the site-specific development of peak bone mass in appendicular and axial skeletal sites and in the trabecular and cortical bone compartments, using both dual x-ray absorptiometry and peripheral computed tomography.

Trabecular volumetric bone mineral density is associated with previous fracture during childhood and adolescence in males: the GOOD study.

Areal bone mineral density (aBMD) measured with dual-energy X-ray absorptiometry (DXA) has been associated with fracture risk in children and adolescents, but it remains unclear whether this association is due to volumetric BMD (vBMD) of the cortical and/or trabecular bone compartments or bone size. The aim of this study was to determine whether vBMD or bone size was associated with X-ray-verified fractures in men during growth. In total, 1068 men (aged 18.
