Purpose : To describe associations of falls and osteoporotic fractures with physical performance in ambulatory adults ≥ 60 years.Methods: A cohort of 405 adults ≥60 years who attended a community activity to evaluate risk factors for osteoporotic fractures and muscle health at the University Hospital. Evaluation included anthropometric measurements, physical performance tests: 4-meter walking speed (WS) [(Normal value (NV) < 5 s), 3-meter Timed Get-Up-and-Go Test(NV≤ 10 s) and Chair sit-to-stand test(NV 20kg for women and >30kg for men). All participants answered a questionnaire about falls in the last year and history of osteoporotic fractures. Weekly physical activities (scored as none, mild and moderate activity), spontaneous loss of weight (>4.5Kg in the last year) and obesity (BMI > 30kg/m2) were considered as possible modifiers of physical performance tests.Results: 321 women aged 69.9 ±7.23yo and 82 men aged 71.96 ± 7.56 yo, with similar BMI in both sexes. Women had worse performance in all tests evaluated than men (p< 0.001). Falls were associated with loss of weight (p=0.004) and altered Grip strength (p=0.026). In women, previous falls were also associated with worse Get-Up-and-Go and Walking Speed tests (p=0.007, 0.003, respectively). Considering obesity, men with BMI>30, showed worse Get-Up-and-Go (p=0.033) and Walking Speed test (p=0.0001) than non obese men. History of osteoporotic fractures was associated with falls, with one or more altered physical performance tests and particulary with altered Chair sit-to-stand test (p=0.023) Physical activity was associated significantly with better physical performance tests (p=0.015-0.001) and Grip strength (p=0.005) Conclusions: Worse physical performance tests were associated with falls and history of osteoporotic fractures. Obesity and sedentary lifestyle were deleterious for physical performance while spontaneous loss of weight seems to be a risk factor for falls.
