Introduction: The reduction in bone density assessedby dual-energy X ray absorptiometry and fall historyrepresent the first two risk factors of non-vertebralfracture. Several publications indicate osteodensitometryto subjects with experienced falls in search of bonefragility and may justify a treatment for osteoporosis.Study purpose: Determine the prevalence of risk factorsjustifying bone densitometry, those of falls, osteoporosisand fractures. Because of the reduce attention accordingto falls, the mean purposes were the evaluation of fall’sfactors, the relation between fall’s history, bone fragilityand fractures risk.Methods: Transversal and descriptive monocentriccohort study conducted for 24 months in 444 patientsreferred by physicians regularly use prescription of BMDby DXA. All patients were interviewed on the risk factorsfor osteoporosis and fractures. Uni and multivarietiesanalyses evaluated the factors of falls in the 12 lastmonths.Results: Data included 410 women and 34 men. Theaverage age was 59.3 years (σ = 12.6). 18.3% of patientshad at least a history of falls in the previous 12 monthsand 22.5 % a history of fracture after a low-energy trauma.42.6 % were osteoporotic. We did not find significantassociation between osteoporosis and fall history (p =0.905). However, in multivariate analysis, risk factorsassociated were : fracture history (p = 0.02), walking aid(p = 0.01), blurred vision ( 0.001), Rheumatoid arthritis (p= 0.02) and diabetes (p = 0.018). Moreover, after adjustingfor other factors, the past of fall was an independantfactor of risk-fractures (p = 0.008).conclusion : This study demonstrates that the fall isa determinant and independent factor of fracture. Dataconfirm the importance to integrate in the practice the pasthistory of fall, the specific risk factors to diagnostic testsas the performance tools to evaluate the risk of fractures.
