Estimated glomerular filtration rate and its association with sarcopenia in elderly people living in the community

Introduction: Factors such as chronic non-communicable diseases and sarcopenia are frequently associated with reduced estimated glomerular filtration rate (eGFR) and lower longevity in older adults. Objective: To evaluate the eGFR and its association with sarcopenia in community-dwelling elderly individuals. Methodology: This population-based cross-sectional study included 548 older adults (≥ 60 years) living in 11 municipalities in the State of Alagoas, Brazil. eGFR was calculated using the Chronic Kidney Disease Epidemiology Collaboration 2021 equation and classified according to kidney disease: Improving Global Outcomes 2024. Sarcopenia was defined based on the European Working Group on Sarcopenia in Older People 2019 criteria. Results: The mean age was 71.5 ± 28.6 years; 67.7% were women, 50.0% were overweight, 67.7% had hypertension, and 32.6% had diabetes. Reduced eGFR (
