Introduction: Osteosarcopenia is a unique geriatric syndrome that can be understood as the concomitant presence of reduced bone mass and reduced muscle mass, amplifying the possible clinical repercussions and the main risk factors of two of the main musculoskeletal disorders that affect the older population. Osteopenia/osteoporosis and sarcopenia have common risk factors, involving modifiable factors, such as lifestyle habits, and non-modifiable factors, such as gender and genetic factors. Objective: To identify the association between osteosarcopenia and physical performance measures in a sample of osteosarcopenic and non-osteosarcopenic community-dwelling older women from an urban center in the Northeast of Brazil. Methods: This is a cross-sectional analytical observational study that evaluated 32 community-dwelling older women with osteosarcopenia and 32 with no osteosarcopenia. Sociodemographic, anthropometric, concern about falls, level of physical activity, depressive symptomatology and functional health assessment data were collected. Body composition was accessed by Dual Energy X-ray Absorptiometry (DXA) and sarcopenia defined based on the European Working Group on Sarcopenia in Older People 2 (EWGSOP2) criteria. Physical performance was obtained by Short Physical Performance Battery (SPPB) and Grip Strength (GS). Pearson's Chi-square was used to identify associations in the sample distributions. Binary Logistic Regression adjusted for age, Body Mass Index, SPPB, and GS was developed to estimate the prediction on osteosarcopenia. Preliminary Results: GS (OR = 0.7, CI 0.58 to 0.86, p-value < 0.001) was significantly associated with presence of osteosarcopenia. There were no significant associations on the SPPB domains.
