Older adults with type 2 diabetes (T2D) tend to have normal or greater areal bone mineral density (aBMD), as measured by DXA, than those who do not have diabetes (non-T2D). Yet risk of fracture is higher in T2D, including 40% to 50% increased hip fracture risk. We used HR-pQCT to investigate structural mechanisms underlying skeletal fragility in T2D. We compared cortical and trabecular bone microarchitecture, density, bone area, and strength in T2D and non-T2D. In secondary analyses we evaluated whether associations between T2D and bone measures differed according to prior fracture, sex, and obesity...

BACKGROUND: The purpose of this study was to determine the clinical opportunities for the use of computed tomography (CT) imaging for inferring bone quality and to critically analyze the correlation between dual x-ray absorptiometry (DXA) and diagnostic CT as reported in the literature. METHODS: A systematic review of the MEDLINE database was performed in February 2016 using the PubMed interface. The inclusion criteria were English language, studies performed using living human subjects, studies pertaining to orthopaedics, use of conventional diagnostic CT scans, studies that measured cancellous bone, and studies that reported Hounsfield unit (HU) measurements directly rather than a computed bone mineral density...

BACKGROUND/OBJECTIVES: Sleep disordered breathing (SDB) has been associated with neurocognitive and behavioral problems in young children; however, this association is less studied in adolescents. Evidence suggests that obesity plays a key role in the development of SDB, although its relative association with neurobehavioral functioning remains unclear. We examined whether SDB and obesity are associated with neurocognitive and behavior problems in adolescents. SUBJECTS/METHODS: 421 adolescents (17...

The detection of changes in lean mass (LM) distribution can help to prevent disability. This study assessed the degree of association between anthropometric measurements and dual-energy X-ray absorptiometry (DXA) body composition (BC) parameters of the upper and lower limbs in a healthy general population and collected DXA age- and sex-specific values of BC that can be useful to build a reference standard. PURPOSE: The primary aim of this study was to investigate the reliability of some widely available anthropometric measurements in the assessment of body composition (BC) at the limbs, especially in terms of muscle mass, in a large sample of healthy subjects of different age bands and sex, using fat mass (FM) and lean mass (LM) parameters derived by dual-energy X-ray absorptiometry (DXA) as the gold standard...

Obese adolescents have increased fracture risk, but effects of alterations in adiposity on bone accrual and strength in obese adolescents are not understood. We evaluated 12-month changes in trabecular and cortical volumetric bone mineral density (vBMD) and cortical geometry in obese adolescents undergoing a randomized weight management program, and investigated the effect of body composition changes on bone outcomes. Peripheral quantitative CT of the radius and tibia, and whole body DXA scans were obtained at baseline, six and 12 months in 91 obese adolescents randomized to standard care versus behavioral intervention for weight loss...

OBJECTIVES: Abdominal fat may be a better predictor than body mass index (BMI) for risk of metabolically-related diseases, such as diabetes, cardiovascular disease, and some cancers. We sought to validate the percent fat reported on dual energy X-ray absorptiometry (DXA) regional spine scans (spine fat fraction, SFF) against abdominal fat obtained from total body scans using the iDXA machine (General Electric, Madison, WI), as previously done on the Prodigy model. METHODS: Total body scans and regional spine scans were completed on the same day (N = 50)...

A retrospective, multicentre study involving 52 patients was carried out to define the causes and characteristics of pregnancy-related osteoporosis. The mean number of vertebral fractures occurring during the last trimester of pregnancy or at the time of delivery was 3.8. This is often promoted by risk factors before or during pregnancy. INTRODUCTION: In order to define the causes or predisposing factors of pregnancy-related osteoporosis and its clinical, radiological and bone density characteristics, laboratory findings, course and outcome, we carried out a retrospective multicentre study...

Population-based screening for osteoporosis is still controversial and has not been implemented. Non-participation in systematic screening was evaluated in 34,229 women age 65-81 years. Although participation rate was high, non-participation was associated with comorbidity, aging other risk factors for fractures, and markers of low social status, e.g., low income, pension, and living alone. A range of strategies is needed to increase participation, including development of targeted information and further research to better understand the barriers and enablers in screening for osteoporosis...

The Nana positioning protocol is widely used to position participants to minimise technical error when undertaking body composition scanning and analysis with a Dual Energy X-Ray Absorptiometry (DXA) machine. Once biological and technical errors are accounted for, the only variation in test re-test results is from statistical fluctuation or machine error. Therefore, the aim of this study is to assess the test re-test reliability of the Nana positioning protocol, and establish the smallest real difference percentage (SRD%)...

Diet and physical activity (PA) influence bone health in children. This study tested whether increasing milk and milk products and weight-bearing types of PA favorably changed bone outcomes assessed by dual-energy X-ray absorptiometry (DXA) and bone biomarkers in children with obesity participating in a 1-year family-centered lifestyle intervention. Children were randomized to one of three groups: Control (Ctrl; no intervention), Standard treatment (StnTx: two servings milk and milk products/day; meet PA guidelines plus weight-bearing PA three times/week), or Modified treatment (ModTx: four servings milk and milk products/day; meet PA guidelines plus daily weight-bearing PA)...

RATIONALE AND OBJECTIVE: Sensitive detection of bone mineral density (BMD) change is a key issue to monitor and evaluate the individual bone health status, as well as bone metabolism and bone mineral status. The ability to use thoracic quantitative computed tomography (QCT) to detect the annual change of BMD remains unclear. We aimed to investigate the sensitivity in detecting age-related bone mineral loss using the thoracic QCT from the electrocardiographically gated heart scans in comparison to whole-body dual-energy X-ray absorptiometry (DXA) and standard lumbar QCT...

BACKGROUND: We previously reported that young men with chronic spinal cord injury (SCI) have a higher prevalence of testosterone deficiency when compared to an age-matched healthy control population. Young men with SCI are also at increased risk for developing cardiometabolic dysfunction after injury. It is unclear whether or not testosterone deficiency is associated with heightened cardiometabolic risk in men with SCI. OBJECTIVE: To investigate associations among levels of testosterone in young men with chronic SCI and surrogate markers of cardiometabolic risk...

BACKGROUND AND OBJECTIVES: The prevalence of cesarean delivery (CD) is rising worldwide, and so is childhood obesity. Studies have shown associations between these factors. We examined the development of BMI from birth through childhood to determine whether CDs were associated with differences in growth and obesity. METHODS: Term children from the birth cohorts Copenhagen Prospective Studies on Asthma in Childhood2000 (COPSAC2000) and COPSAC2010 were included. Height, length, and weight measurements were collected prospectively until 5 years in COPSAC2010 and until 13 years in COPSAC2000...

OBJECTIVE: We recently investigated the effect of ipragliflozin, a sodium glucose co-transporter-2 inhibitor (SGLT-2I), in Japanese patients with type 2 diabetes by a 24-week. SGLT-2Is also have an anti-obesity effect, and reduction of body fat has been demonstrated by indirect methods. However, evaluation of the effect on the total visceral fat volume and intrahepatic lipid content has not been performed. RESEARCH DESIGN AND METHODS: We measured the abdominal subcutaneous fat volume (SFV) and visceral fat volume (VFV) by whole abdominal CT scanning, the intrahepatic lipid (IHL) content by proton magnetic resonance spectroscopy (1H-MRS), and the fat mass index (FI) and appendicular skeletal mass index (ASMI) by dual X-ray absorptiometry (DXA) in 20 patients from our previous study...

Proximal femoral fractures can be categorized into two main types: Neck and intertrochanteric fractures accounting for 53% and 43% of all proximal femoral fractures, respectively. The possibility to predict the type of fracture a specific patient is predisposed to would allow drug and exercise therapies, hip protector design, and prophylactic surgery to be better targeted for this patient rendering fracture preventing strategies more effective. This study hypothesized that the type of fracture is closely related to the patient-specific femoral structure and predictable by finite element (FE) methods...

BACKGROUND: The Dual Energy X-Ray Absorptiometry (DXA) is the gold standard for measuring BMD and bone mineral content (BMC). In general, DXA is ideal for pediatric use. However, the development of specific standards for particular geographic regions limits its use and application for certain socio-cultural contexts. Additionally, the anthropometry may be a low cost and easy to use alternative method in epidemiological contexts. The goal of our study was to develop regression equations for predicting bone health of children and adolescents based on anthropometric indicators to propose reference values based on age and sex...

This study compares four screening tools in their ability to predict osteoporosis. We found that there was no significant difference between the tools. These results provide support for the use of automated screening tools which work in conjunction with the electronic medical record and help improve screening rates for osteoporosis. INTRODUCTION: The purpose of this study is to compare the performance of four fracture risk assessment tools (FRATs) in identifying osteoporosis by bone mineral density (BMD) T-score: Veterans Affairs Fracture Absolute Risk Assessment Tool (VA-FARA), World Health Organization's Fracture Risk Assessment Tool (FRAX), electronic FRAX (e-FRAX), and Osteoporosis Self-Assessment Screening Tool (OST)...

Trabecular bone score (TBS) assesses bone quality in the lumbar spine using dual-energy X-ray absorptiometry (DXA) scans. In postmenopausal women with osteoporosis, denosumab significantly improved TBS independently of bone mineral density (BMD). This practical technique may have a role in managing patients with osteoporosis. INTRODUCTION: TBS, a gray-level texture index determined from lumbar spine DXA scans, correlates with bone microarchitecture and enhances assessment of vertebral fracture risk independently of BMD...
