[Anemia increases mortality risk associated with frailty or disability in older adults. The FRADEA Study]
Abstract
Objective: To analyze if anemia increases 10-year mortality risk associated to frailty and disability in older adults.
Design: Substudy of the FRADEA population-based concurrent cohort study (Frailty and dependence in Albacete), with a 10-year follow-up (2007-2017) in people older than 69years.
Setting: Albacete city, Spain.
Participants: Of the 993 participants included in the first wave, 790 were selected with valid data on function (frailty and disability), anemia and vital status at 10years.
Main measurements: Anemia was defined according to the criteria of the World Health Organization (hemoglobin <13g/dL in men and <12g/dL in women). A functional classification variable was created, including frailty and disability, identifying four progressive functional levels: robust, prefrail, frail and disabled in basic activities of daily life, using frailty phenotype and Barthel index respectively. A new eight categories variable was constructed combining the four functional groups with the presence or absence of anemia. The association with mortality was determined by Kaplan-Meier and Cox proportional hazards analysis adjusted for age, sex, comorbidity, polypharmacy, institutionalization and creatinine.
Results: Mean age was 79years and 59.6% were women. 393 participants (49.7%) died during the follow-up period. The median survival was 98.4months (interquartile range 61). The risk of mortality increased from the levels with better functionality to those with worse functionality, and for each subgroup it was higher in the participants with anemia. Prefrail without anemia HR [hazard ratio] 1.59 (95%CI 1.07-2.36) and with anemia HR 2.37 (95%CI 1.38-4.05). Frail without anemia HR 3.18 (95%CI 1.68-6.02) and with anemia HR 4.42 (95%CI 1.99-9.84). Disabled without anemia HR 3.81 (95%CI 2.45-5.84) and with anemia HR 5.48 (95%CI 3.43-8.76).
Conclusion: Anemia increases the risk of mortality associated with frailty and disability in older adults.
Objetivo: Analizar si la presencia de anemia incrementa el riesgo de mortalidad a largo plazo asociado al estado de fragilidad y discapacidad en adultos mayores.
Diseño: Subestudio de la cohorte concurrente de base poblacional FRADEA (Fragilidad y Dependencia en Albacete), con 10 años de seguimiento (2007-2017), en mayores de 69 años.
Emplazamiento: Albacete capital, España.
Participantes: De los 993 participantes incluidos en la primera oleada se seleccionaron 790 sujetos con datos válidos de función (fragilidad y discapacidad), anemia y estado vital a los 10 años.
Mediciones principales: La anemia se definió según los criterios de la Organización Mundial de la Salud (hemoglobina < 13 g/dl en hombres y < 12 g/dl en mujeres). Se creó la variable «clasificación funcional» incluyendo fragilidad y discapacidad, e identificando cuatro niveles progresivos: robusto, prefrágil, frágil y con discapacidad en actividades básicas de la vida diaria, empleando el fenotipo de fragilidad e índice de Barthel, respectivamente. Se construyó una nueva variable de ocho categorías combinando las cuatro funcionales con la presencia o ausencia de anemia. La asociación con mortalidad se determinó mediante Kaplan-Meier y análisis de riesgos proporcionales de Cox ajustado por edad, sexo, comorbilidad, polifarmacia, institucionalización y creatinina.
Resultados: Edad media 79 años, siendo el 59,6% mujeres. Un total de 393 participantes (49,7%) fallecieron durante el periodo de seguimiento. La mediana de supervivencia fue de 98,4 meses (rango intercuartil 61). El riesgo de mortalidad aumentó desde los niveles con mejor clasificación funcional hasta aquellos con peor, y para cada subgrupo fue mayor en los participantes con anemia. Prefrágiles sin anemia hazard ratio (HR): 1,59, IC 95%: 1,07-2,36, y con anemia HR: 2,37, IC 95%: 1,38-4,05. Frágiles sin anemia HR: 3,18, IC 95%: 1,68-6,02, y con anemia HR: 4,42, IC 95%: 1,99-9,84. Discapacitados sin anemia HR: 3,81, IC 95%: 2,45-5,84, y con anemia HR: 5,48, IC 95%: 3,43-8,76.
Conclusión: La anemia incrementa el riesgo de mortalidad asociado a la fragilidad y discapacidad en adultos mayores.
