Up-to-date knowledge of frailty

Background: Frailty is a state in which the functional reserves of multiple organs body are reduced significantly, making an individual vulnerable to variety stressors. As result, frail individuals more likely experience falls, disability, and even mortality. can be reversible preventable many cases with specific modalities, such as exercise, protein-calorie supplementation, vitamin D intake, reducing polypharmacy. The frailty phenotype index most common methods used diagnose frailty. In United Kingdom, primary care physicians must use electronic identify all patients aged ≥65 years.Current Concepts: Korean aging cohort study, multicenter longitudinal study taking place Korea, has identified some important factors management middle-old age group (70-79 years old), high-level physical activities were associated lower incidence after 2 years, but no effect thereof was observed oldest-old (80-84 old). Physical improvement from activities, those prefrailty at least middle-level activities.Discussion Conclusion: For prevention frailty, participants level activity determine success interventions. Protein intake 1.5 g/kg/day needed improve not only muscle mass also gait speed prefrail or elderly patients, especially risk malnutrition, short-term period.
