[Detection of the largest population susceptible to prescription of a program of exercises in Primary Care to prevent frailty]. / Detección de la población mayor susceptible de prescripción de un programa de ejercicios en Atención Primaria para prevenir la fragilidad.

AIM: Identify the population over 70 year's old treated in primary care who should participate in a physical exercise program to prevent frailty. Analyze the concordance among 2criteria to select the beneficiary population of the program. DESIGN: Population-based cross-sectional study. SETTINGS: Primary Care. PARTICIPANTS: Elderly over 70 years old, living in the Peñagrande neighborhood (Fuencarral district of Madrid) from the Peñagrande cohort, who accepted to participate in 2015 (n = 332). MAIN MEASUREMENTS: The main variable of the study is the need for exercise prescription in people over 70 years old at the Primary Care setting. It was identified through 2different definitions: Prefrail (1-2 of 5 Fried criteria) and Independent individuals with physical performance limited, defined by Consensus on frailty and falls prevention among the elderly (independent and with a total SPPB score <10). RESULTS: The 63,8% of participants (n = 196) need exercise prescription based on criteria defined by Fried and/or the consensus for prevention of frailty and falls in the elderly. In 82 cases the 2criteria were met, 80 were prefrail with normal physical performance and 34 were robust with a limited physical performance. The concordance among both criteria is weak (kappa index 0, 27). CONCLUSION: Almost 2thirds of the elderly have some kind of functional limitation. The criteria of the consensus document to prevent frailty detect half of the pre-frail individuals in the community.
