Estudio NonaSantfeliu. Valoración inicial y 10 años de seguimiento

NonaSantfeliu study: A review is presented of the studies that are part of the initial overall assessment and the studies performed during the 10 years of follow-up of a cohort of nonagenarians. It is a population-based study of 186 subjects, 76.5% women, mean age at baseline of 93.06 years, a quarter (26%) being institutionalized. The mean of baseline Barthel index was 60.8, and the mean for the Lobo's cognitive minimental was 21. Nonagenarian males with low comorbidity had more successful aging criteria than women with high comorbidity quantified with the Charlson Index. The survival rate at 10 years follow-up was very low, and 95.6% of the population had died. This represented an annual mortality rate of 9.5%. A common denominator on assessing all different annual cuts, is that the most important factors associated with mortality are those related to geriatric assessment, such as a function, cognition, dementia, and cumulative comorbidity and multiple medications, compared to more traditional risk factors described in younger populations.
