Change in the pattern of frailty among socially vulnerable older adults over a 36-month period and associated factors: a follow-up study

Abstract

Objective: To investigate changes in the frailty levels of older adults in a context of high social vulnerability. Methods: We conducted a prospective cohort study. Data were collected from 2 surveys conducted in 2015 and 2018. The frailty phenotype and sociodemographic and health characterization instruments were used. Descriptive statistical analysis was performed, including non-parametric tests, test for equality of proportions, and multivariate multinomial logistic regression. The use of the database was authorized, and the research was approved by the Ethics Committee. Results: In 2015, 346 community-dwelling older adults participated in the study. After 36 months, a final sample of 223 participants was obtained. In 2015, the prevalence of non-frail, pre-frail, and frail older adults was 13.0%, 56.5%, and 30.5%, respectively. In 2018, 22.9% were non-frail, 56.0% were pre-frail, and 21.1% were frail. Higher education and better quality of life reduced the likelihood of becoming pre-frail and frail, respectively. Conclusion: There was a change in the pattern of frailty among socially vulnerable older adults over a 36-month period.
