Abstract
The population is aging throughout the world. Preserving physical and cognitive functions is crucial to successful aging. The aim of this study was to determine the proportion of 85-year-old community-dwelling subjects aging successfully, applying a quantitative approach, and assessing the association of successful aging with sociodemographic data, global geriatric assessment, and co-morbidity. This was a community-based survey of inhabitants aged 85 years, with 328 out of 487 subjects born in 1924 assigned to seven primary health-care teams, representing a participation rate of 67.5%. Sociodemographic variables, Barthel index (BI), the Spanish version of the Mini-Mental State Examination (MEC), Mini Nutritional Assessment (MNA), Charlson Index, Gait Rating Scale, social risk, quality of life (QoL), and prevalent chronic diseases were assessed. Subjects scoring higher than 90 on the BI and higher than 24 on the MEC were compared with the rest. Multiple regression analysis was performed. Using these criteria, successful aging status was defined in 162 (49.3%) subjects. Using multiple logistic regression analysis, successful agers had significantly lower co-morbidity scores (p < 0.02, odds ratio [OR] = 0.791, 95% confidence interval [CI] 0.657-0.952), higher scores on the Gait Rating Scale identifying lower risk of falls (p < 0.0001, OR = 1.753, 95% CI 1.501-2.046), and higher scores on the MNA, indicating lower risk of malnutrition (p < 0.0001, OR = 1.190, 95% CI 1.090-01.299). Regarding QoL, successful agers had significantly higher values than their unsuccessful aging counterparts (p > 0.0001). Almost half of the individuals presented successful aging. Successful agers had less co-morbidity and a lower risk of falls or malnutrition, and they had higher scores on the QoL scale.
