Frailty in younger-old and oldest-old adults in a context of high social vulnerability

OBJECTIVE: To analyze the factors associated with physical frailty in community-dwelling younger-old (60 to 74 years) and oldest-old (75 years or older) adults in a region of high social vulnerability. Social vulnerability refers to the absence of or difficulty obtaining social support from public institutions, situations that hinder the realization of or deny citizens their social rights and affect their social cohesion, and the ability to react to high-risk social situations – associated health and illness. In this study, we used the São Paulo Social Vulnerability Index developed by the SEADE Foundation, which classifies social vulnerability based on socioeconomic and demographic conditions. METHODS: Quantitative analytical study of 303 older adults. Fried frailty phenotype assessment was performed and the Mini Mental State Examination, Geriatric Depression Scale, Katz Index of Independence in Activities of Daily Living, and the Lawton Scale of Instrumental Activities of Daily Living were administered. Descriptive statistics and logistic regression were used to analyze data. RESULTS: Of the older adults, 12.21% were nonfrail, 60.72% were prefrail, and 27.06% were frail. The single factor most associated with frailty was depressive symptoms (OR = 2.65; 95%CI 1.38 – 5.08) in the younger-old and illiteracy (OR = 14.64; 95%CI 1.82 – 116.51) in the oldest old. CONCLUSION: The factor most associated with frailty in younger-old adults (aged 60 to 74 years) was depressive symptoms, whereas in the oldest old (aged 75 or older), the factor most associated with frailty was being illiterate. The results of this investigation should prompt health professionals and managers to discuss and program new strategies for health promotion and prevention of factors that may aggravate frailty, respecting the differences found between older adults in early and later old age.
