[Successful aging and indicators of frailty in the elderly. Octabaix Study]. / Envejecimiento satisfactorio e indicadores de fragilidad en los mayores de la comunidad. Estudio Octabaix.

UNLABELLED: Successful aging as a process of adaptation to the optimal state is little known in older people. OBJECTIVE: To describe successful aging and to analyze the factors associated with frailty in people aged 86 years. DESIGN: A cross-sectional study of a clinical trial at the second year of follow-up (Octabaix Study). SETTING: Seven Primary Care Centers. PARTICIPANTS: Non-institutionalized subjects born in 1924. MAIN MEASUREMENTS: Data on sociodemographic, comorbidity and geriatric assessment scales were collected. Frailty was defined by the presence of 3 or more of the following criteria: muscle weakness, slow walking, weight loss, exhaustion, low physical activity. Successful aging was defined as: Barthel index >90/100 and Lobo test ≥ 24/35. Multiple regression analysis was performed. RESULTS: A total of 273 patients were evaluated, 39.2% men. The prevalence of successful aging was 47.2% (129). In the unsuccessful aging, the frailty prevalence was 34.7% (50). The frailty factors associated with unsuccessful aging were low activity (OR: 7.56; 95%CI: 3.8 -14.9), weakness (OR: 6.08; 95%CI: 2.5-14.7), slowness (OR: 5.1; 95%CI: 2.8-9.5), and exhaustion (OR: 3.6; 95%CI: 1.6-8.3). The prevalence of successful aging is high in 86-year-old community-dwelling subjects. The low physical activity multiplied by seven, and muscle weakness by 6, were the factors most associated with unsuccessful aging. Therefore, incorporating screening designed to detect these two factors could improve future interventions towards more optimal aging in the community, if these results are confirmed in future studies.

Envejecimiento satisfactorio e indicadores de fragilidad en los mayores de la comunidad. Estudio Octabaix / Successful aging and indicators of frailty in the elderly. Octabaix Study

El envejecimiento satisfactorio como estado óptimo de un proceso de adaptación es poco conocido en las personas más mayores. OBJETIVO: Describir envejecimiento satisfactorio y analizar su asociación con indicadores de fragilidad en personas de 86 años. DISEÑO: Estudio descriptivo transversal al segundo año de seguimiento de un ensayo clínico (estudio Octabaix). Emplazamiento: Siete centros de atención primaria. Participantes: Personas nacidas en 1924, no institucionalizadas. Medidas principales: Se recogieron datos sociodemográficos, comorbilidad y escalas de valoración geriátrica. La fragilidad se definió por presencia de 3 o más de los siguientes criterios: debilidad muscular, lentitud en la marcha, pérdida de peso, agotamiento y escasa actividad física. El envejecimiento satisfactorio se definió según: índice de Barthel > 90/100 y test de Lobo ≥ 24/35. Se realizó un análisis descriptivo bivariante y multivariante mediante regresión logística. RESULTADOS: Se evaluaron 273 pacientes, 39,2% hombres. La prevalencia de envejecimiento satisfactorio fue del 47,2% (129). En el grupo sin envejecimineto satisfactorio existía una proporción de fragilidad del 34,7% (50). Se hallaron como criterios de fragilidad asociados a envejecimiento no satisfactorio la escasa actividad (OR: 7,56; IC 95%: 3,8-14,9), la debilidad (OR: 6,08; IC 95%: 2,5-14, 7), la lentitud (OR: 5,1; IC 95%: 2,8-9,5) y el agotamiento (OR: 3,6; IC 95%: 1,6-8,3). La prevalencia de envejecimiento satisfactorio es elevada en personas de 86 años en la comunidad. La escasa actividad física multiplica por 7 la asociación a envejecimiento no satisfactorio, y la debilidad muscular por 6. Por ello, incorporar el cribado dirigido a detectar estos 2 factores podría mejorar intervenciones posteriores hacia un envejecimiento más óptimo, si estos resultados se confirman en futuros estudios
