Risk factors for fracture of the neck of the femur are relatively well established, but those for fracture at other sites are little studied. In this large population study we explore the role of age, body mass index (BMI), and physical activity on the risk of fracture at seven sites in postmenopausal women. As part of the Million Women Study, 1,154,821 postmenopausal UK women with a mean age o...

BACKGROUND AND PURPOSE Stroke is a documented risk factor for hip fracture. However, no documented studies are available on the risk of stroke among patients with hip fracture. This study investigated the frequency and risk of stroke after hip fracture using a nationwide population-based study. METHODS The study cohort included 2101 patients hospitalized with a principal diagnosis of hip frac...

BACKGROUND This is the first longitudinal study with a 22-year follow-up, based on a national and complete sample, to determine whether the prevalence of hip fracture and the age when it occurs are influenced by migration and by being foreign-born. Cultural background and environmental factors such as UV-radiation and lifestyle during childhood and adolescence may influence the risk of a hip fr...

Aims This paper describes the history, purpose, data collection and contributions in the research collaboration Norwegian Osteoporosis Epidemiologic Studies (NOREPOS). Methods NOREPOS encompasses almost 85,000 bone mineral density measurements within Cohort of Norway and data on almost 140,000 hip fractures in Norway 1994-2008. Included are anthropometric measurements, blood pressure, lipids an...

BACKGROUND We investigated risk factors for fracture among young adults, particularly body mass index (BMI) and physical activity, which although associated with fracture in older populations have rarely been investigated in younger people. METHODS In 2009, 4 years after initial recruitment, 58 204 Thais aged 19 to 49 years were asked to self-report fractures incident in the preceding 4 years...

UNLABELLED In March 2008, FRAX, developed by Kanis and collaborators in the University of Sheffield and supported by the World Health Organization, became available online to calculate absolute risk of osteoporotic fracture in the next 10 years. OBJECTIVE To analyze the risk of fracture calculated by FRAX and its determinants in the patients sent to a densitometry unit for bone mineral densit...

BACKGROUND Child abuse represents a serious threat to the health and well-being of the pediatric population. Orthopaedic specialists will often become involved when child abuse is suspected as a result of the presence of bony injury. Distinguishing abuse from accidental trauma can be difficult and is often based on clinical suspicion. QUESTIONS/PURPOSES We sought to determine whether accident...

Natural and artificial materials including rocks and cement-based materials such as concrete and cement mortar are affected both physically and chemically by various natural factors known as weathering factors. The freeze-thaw process, as a weathering factor, considerably affects the properties of rocks and concrete. Therefore, the effect of the freeze-thaw process on the physical and mechanica...

BACKGROUND Since the reference value is the core factor of the T-score calculation, it has a significant impact on the prevalence of osteoporosis. The purpose of this study was to determine the effects of using the Korean reference value on the prevalence of osteoporosis and on the prediction of fracture risk. METHODS We used femoral neck bone mineral density (BMD) data from the Korea Nationa...

A cross-sectional study was performed to assess bone health history among aromatase inhibitor (AI) users before breast cancer (BC) diagnosis, which may impact fracture risk after AI therapy and choice of initial hormonal therapy. A total of 2,157 invasive BC patients initially treated with an AI were identified from a prospective cohort study at Kaiser Permanente Northern California (KPNC). Dat...
