- W2725319845 abstract "Introduction: Some factors that contribute to active aging can benefit the raising number of oldest old people. Vitamin D and life style have shown impact on functionality and mortality. Objective: Evaluating if 25(OH)D, outdoor activity time and falls are predictors of survival in independent oldest old. Methods: We selected 258 community-dwelling and independent elderly people with 80 years old or more. We evaluated the mortality through the death certificate or register in medical records from April 2010 to March 2016. During the survival analysis, we have used the models of Kaplan-Meier and Cox. Results: Around 70.5% were women between 80 to 89 years old (80.2%), 38.8% had daily sunlight exposure superior to 15 minutes and 20.1% were chronic fallers. Regarding 25(OH)D, 9.3% had serum levels 30 ng/mL. During the observational period, 65.9% of the old oldest have stayed independent, and 17.1% have deceased. The analysis of survival time have shown that men (HR=2.7, p=0.003), over 90 years old (HR= 4.12, p<0.001), with levels of 25(OH)VitD inferior to 10 ng/mL (HR=3.2, p=0.004) and chronic fallers (HR=1.97, p=0.042) have shown a lower survival in comparison to the other oldest old. Conclusion: This study has identified a profile of oldest old more susceptible to a higher risk of death." @default.
