abstract = {Introducción: En personas mayores la sarcopenia es un síndrome multifactorial, asociado con 
diversos eventos adversos como discapacidad, caídas y mortalidad.
Objetivo: Analizar los factores clínicos, hábitos y estilos de vida asociados a sarcopenia en per sonas mayores residentes en la comunidad. 
Método: Estudio observacional, descriptivo transversal realizado en Talca, Chile, entre junio y 
noviembre de 2024. Participaron 201 personas mayores con una edad media de 71,6 años 
(89,4 % mujeres). La sarcopenia fue diagnosticada según criterios internacionales, mientras 
que los antecedentes clínicos (comorbilidades y estado nutricional), hábitos y estilos de vida se 
obtuvieron mediante autorreporte. Se realizó un análisis de regresión logística binaria y los re sultados se expresaron en odds ratios (OR) con sus respectivos intervalos de confianza al 95 % 
(IC 95 %) y p < .05. 
Resultados: La prevalencia de sarcopenia fue del 6,67 %. Se observó mayor probabilidad de 
sarcopenia en presencia de polifarmacia (OR = 4,03; IC 95 %: 1,09–18,97; p = .03), artrosis (OR 
= 4,44; IC 95 %: 1,08–20,87; p = .03) y déficit auditivo (OR = 4,00; IC 95 %: 1,15–13,86; p = .02). 
En contraste, el sobrepeso/obesidad se asoció con menor riesgo de desarrollar esta condición 
(OR = 0,047; IC 95 %: 0,006–0,371; p = .04). 
Conclusión: La polifarmacia, la artrosis y el déficit auditivo, se mostraron como factores de 
riesgo para la sarcopenia mientras que el sobrepeso/obesidad se asoció con un menor riesgo 
de desarrollarla. Estos hallazgos aportan evidencia para fortalecer las estrategias de tamizaje, 
prevención e intervención temprana en el contexto de la atención primaria, considerando un 
enfoque multidimensional.},
abstract = {Introduction: In older adults the sarcopenia is a multifactorial syndrome associated with sev eral adverse outcomes, including disability, falls, and mortality. 
Objective: To analyze the clinical, lifestyle, and behavioral factors associated with sarcopenia in 
community-dwelling older adults. 
Methods: A cross-sectional, observational, and descriptive study was conducted in Talca, Chile, 
between June and November 2024. A total of 201 older adults participated, with a mean age of 
71.6 years; 89.4% were women. Sarcopenia was diagnosed according to international criteria, 
while clinical variables (comorbidities and nutritional status), lifestyle behaviors, and habits 
were obtained through self-report. Binary logistic regression analysis was performed, and the 
results were expressed as odds ratios (OR) with corresponding 95% confidence intervals (95% 
CI) and statistical significance set at p < .05. 
Results: The prevalence of sarcopenia was 6.97%. A higher likelihood of sarcopenia was ob served in the presence of polypharmacy (OR = 4.03; 95% CI: 1.09–18.97; p = .03), osteoarthritis 
(OR = 4.44; 95% CI: 1.08–20.87; p = .03), and hearing impairment (OR = 4.00; 95% CI: 1.15–
13.86; p = .02). In contrast, overweight/obesity was associated with a significantly lower risk 
of developing sarcopenia (OR = 0.047; 95% CI: 0.006–0.371; p = .04).
Conclusion: Polypharmacy, osteoarthritis, and hearing impairment were positively associated 
with sarcopenia, while overweight/obesity was inversely associated with its presence. These 
findings provide evidence to reinforce screening, prevention, and early intervention strategies 
within primary healthcare settings, emphasizing a multidimensional approach.},
