Prevalence of and factors associated with successful aging in Brazilian older adults: Frailty in Brazilian older...

We aimed to estimate the factors associated with the biomedical dimension of successful aging (SA) and its prevalence in older Brazilian individuals. The conceptual framework for this approach relies on the considerable variation in the biophysiological effects of aging and the need to understand the factors that influence this process.

Data from a total of 845 older adults were analyzed. SA operationalization included the following criteria: good physical and cognitive performance, absence of disabilities, and good health conditions. Descriptive analyses were used to estimate the prevalence of SA, and the factors associated with SA were assessed using multivariate logistic regressions.

The overall prevalence of SA was 25%, and the associated factors were the absence of (OR 10.5, 95% CI 5.2-21.1) or fewer than two physical morbidities (OR,3.5, 95% CI 2.1-5.9), body mass index in the overweight range (OR 1.8, 95% CI 1.02-3.3), absence of depression (OR ,2.1, 95% CI 1.07 = 4.1), high levels of physical activity (OR 1.88, 95% CI 1.14-3.2), high levels of social participation (OR 2.07, 95% CI 1.16-3.4) and younger age (65-74 years, OR 4.27, 95% CI 1.79-10.1; 75-84 years, OR 2.7, 95% CI 1.18-6.41).

A small proportion of older adults met the criteria defining successful aging. Despite the great impact of biological determinants, modifiable social and lifestyle factors predicted successful aging in this population, suggesting that health promotion targeting behavioral changes might lead to tangible benefits for health and well-being in old age.
