Abstract(s)
A Sarcopenia Ă© uma condição multifatorial caracterizada pela perda progressiva de força, função e massa muscular, associada ao envelhecimento e fortemente correlacionada com desnutrição, dependĂȘncia funcional e risco aumentado de queda. A sua elevada prevalĂȘncia em contextos hospitalares justifica a implementação de estratĂ©gias de
rastreio sistemåtico e intervençÔes precoces.
Objetivo: Avaliar a prevalĂȘncia da Sarcopenia em idosos internados num serviço de medicina interna a aguardar integração na Rede Nacional de Cuidados Continuados
Integrados, e identificar os fatores clĂnicos, funcionais e nutricionais associados Ă Sarcopenia.
MĂ©todos: Estudo descritivo, transversal e de natureza quantitativa, realizado numa amostra de conveniĂȘncia composta por 100 idosos internados num serviço de medicina interna de uma Unidade Local de SaĂșde no norte do paĂs. O protocolo de recolha de dados incluiu informaçÔes sociodemogrĂĄficas, clĂnicas e funcionais. A Sarcopenia foi avaliada pelo questionĂĄrio SARC-F.
Resultados: A prevalĂȘncia de Sarcopenia na admissĂŁo foi de 95%, com uma mĂ©dia de pontuação SARC-F de 7,3 ± 1,5. Observaram-se correlaçÔes negativas significativas entre a
gravidade da Sarcopenia e o estado nutricional (R = -0,377; p < 0,001), força de preensĂŁo palmar (R = -0,253; p = 0,013), perĂmetro gemelar (R = -0,373; p < 0,001) e nĂvel de
independĂȘncia funcional (p < 0,001). A maioria dos participantes apresentava desnutrição (57,9%), dĂ©fice cognitivo (58,9%) e alto risco de queda (60%).
ConclusĂŁo: A Sarcopenia revela uma prevalĂȘncia alarmante entre idosos hospitalizados, estando fortemente associada a desnutrição, diminuição da força muscular e elevada
dependĂȘncia funcional.
Sarcopenia is a multifactorial condition characterized by progressive muscle strength, function, and mass loss. It is closely associated with aging and strongly correlated with malnutrition, functional dependence, and an increased risk of falls. Its prevalence in hospital settings underscores the need for systematic screening strategies and early interventions. Objective: To evaluate the prevalence of sarcopenia among older adults hospitalized in an Internal Medicine ward while awaiting placement in the National Network for Integrated Continuous Care, and to identify clinical, functional, and nutritional factors associated with sarcopenia. Methods: This was a descriptive, cross-sectional, quantitative study conducted with a convenience sample of 100 older adults hospitalized in an internal medicine ward of a Local Health Unit in Northern Portugal. The data collection protocol included sociodemographic, clinical, and functional information. Sarcopenia was assessed using the SARC-F questionnaire. Results: The prevalence of sarcopenia at admission was 95%, with a mean SARC-F score of 7.37,3± 1,5. Significant negative correlations were found between sarcopenia severity and nutritional status (R = -0.377; p < 0.001), handgrip strength (R = -0.253; p = 0.013), calf circumference (R = -0.373; p < 0.001), and level of functional independence (p < 0.001). Most participants presented with malnutrition (57.9%), cognitive impairment (58.9%), and a high risk of falling (60%). Conclusion: Sarcopenia shows an alarming prevalence among hospitalized older adults and is strongly associated with malnutrition, reduced muscle strength, and high functional dependence.
