Reductions in Disability Prevalence Among the Highest Income Groups of Older Brazilians

Reductions in Disability Prevalence Among the Highest Income Groups of Older Brazilians Objectives. We sought to identify the income–disability prevalence relationship among older Brazilians. Methods. Data were from 63 985 individuals 60 years and older from the 1998 and 2003 Brazilian National Household Surveys. Generalized additive logistic models with cubic regression splines were used to estimate the disability–income relationships. Results. There was a strong linear relationship between increased income and reduced disability prevalence for most of the income distribution. Benefits were still present above the 90th percentile of income but were more modest. Because incomes among the wealthiest few are disproportionately large, odds ratios of disability nevertheless showed marked improvements, even across the very highest income groups. Conclusions. Among older Brazilians, reduced disability is associated with higher income, and these associations are present even above the 90th percentile of income. In addition to understanding mechanisms of disability reduction among impoverished individuals, work is needed to understand these mechanisms in middle- and high-income groups. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png American Journal of Public Health American Public Health Association

Abstract

Objectives. We sought to identify the income–disability prevalence relationship among older Brazilians. Methods. Data were from 63 985 individuals 60 years and older from the 1998 and 2003 Brazilian National Household Surveys. Generalized additive logistic models with cubic regression splines were used to estimate the disability–income relationships. Results. There was a strong linear relationship between increased income and reduced disability prevalence for most of the income distribution. Benefits were still present above the 90th percentile of income but were more modest. Because incomes among the wealthiest few are disproportionately large, odds ratios of disability nevertheless showed marked improvements, even across the very highest income groups. Conclusions. Among older Brazilians, reduced disability is associated with higher income, and these associations are present even above the 90th percentile of income. In addition to understanding mechanisms of disability reduction among impoverished individuals, work is needed to understand these mechanisms in middle- and high-income groups.
