All-cause mortality over a three-year period among community-dwelling older adults in Southern Brazil

ABSTRACT: Objective: To evaluate all-cause mortality in approximately three years of follow-up and related sociodemographic, behavioral and health factors in community-dwelling older adults in Pelotas, RS. Methods: This was a longitudinal observational study that included 1,451 older adults (≥ 60 years) who were interviewed in 2014. Information on mortality was collected from their households in 2016–2017 and confirmed with the Epidemiological Surveillance department of the city and by documents from family members. Associations between mortality and independent variables were assessed by crude and multiple Cox regression, with hazard ratio with respective 95% confidence intervals (95%CI). Results: Almost 10% (n = 145) of the participants died during an average of 2.5 years of follow-up, with a higher frequency of deaths among males (12.9%), ?80 years (25.2%), widowhood (15.0%), no education (13.8%) and who did not work (10.5%). Factors associated with higher mortality were: being a male (HR = 2.8; 95%CI 1.9 – 4.2), age ?80 years (HR = 3.9; 95%CI 2.4 – 6.2), widowhood (HR = 2.2; 95%CI 1.4 – 3.7), physical inactivity (HR = 2.3; 95%CI 1.1 – 4..6), current smoking (HR = 2.1; 95%CI 1.2 – 3.6), hospitalizations in the previous year (HR = 2.0; 95%CI 1.2 – 3.2), depressive symptoms (HR = 2.0; 95%CI 1.2 – 3,4) and dependence for two or more daily life activities (HR = 3.1; 95%CI 1,7 – 5.7). Conclusion: The identification of factors that increased the risk of early death makes it possible to improve public policies aimed at controlling the modifiable risk factors that can lead to aging with a better quality of life.
