Introduction Sarcopenia and sarcopenic obesity (SO) have emerged as significant contributors to negative health outcomes in the past decade. We aimed estimate prevalence of probable sarcopenia, SO a community-dwelling population 1151 adults aged ≥55 years Lima, Peru. Methods This cross-sectional study was conducted between 2018 2020. defined presence low muscle strength (LMS) mass (LMM) according European (EWGSOP2), US (FNIH) Asian (AWGS2) guidelines. measured by maximum handgrip using bioelectrical impedance analyzer. body index ≥ 30 kg/m 2 sarcopenia. Results The participants had mean age 66.2 (SD 7.1), range 60 92 old, which 621 (53.9%) were men. Among sample, 41.7% classified obese (BMI ≥30.0 kg/m²). sarcopenia estimated be 22.7% (95%CI: 20.3–25.1) EWGSOP2 criteria 27.8% 25.2–30.4) AWGS2 criteria. prevalence, assessed skeletal (SMI), 5.7% 4.4–7.1) 8.3% 6.7–9.9) based on FNIH 18.1% 15.8–20.3). SO, considering different definitions, ranged from 0.8% 0.3–1.3) 5.0% 3.8–6.3). Conclusion Our findings reveal substantial variation underscoring necessity for context-specific cut-off values. Although relatively low, this result may underestimated. Furthermore, consistently high proportion point public burden.
