Sarcopenia in Older Adults: Towards better assessment, lifestyle interventions, and interprofessional care

Sarcopenia, defined as the progressive loss of muscle mass and strength, and malnutrition, characterized by an imbalance in energy or nutrient intake, are common conditions in older adults. Both are associated with impaired daily functioning, reduced independence, lower quality of life, and increased mortality risk.

This thesis evaluated tools for sarcopenia screening, diagnosis, and severity assessment (Part I), examined the feasibility of combined exercise and nutrition interventions to improve nutritional intake and physical performance (Part II), and explored the perspectives of healthcare professionals and older adults on interprofessional collaboration for treatment of sarcopenia and malnutrition (Part III). Improving care for older adults at risk of sarcopenia and malnutrition requires accurate, context-specific diagnostics, tailored and feasible interventions, and strong collaboration among healthcare professionals and patients. Addressing these components is crucial for improving outcomes and quality of life in this vulnerable population.
