Brazilian survey links social inequalities to diabetes and hypertension burden
A cross-sectional analysis of 21,690 Brazilian adults found higher self-reported diabetes and hypertension prevalence among groups facing intersecting social disadvantages. Low educational attainment was associated with a greater burden of both conditions, although the survey design cannot establish causation.
- Analysis included 21,690 adults in Brazil’s 2023 Vigitel survey.
- Low-education groups had higher prevalence across all assessed conditions.
- The cross-sectional, self-reported data cannot establish causation.
Researchers analyzed data from Brazil’s 2023 Vigitel National Survey, including 21,690 adults aged 18 years or older. The cross-sectional study assessed self-reported diabetes, hypertension, and their co-occurrence in relation to sex, race/color, and educational attainment. The analysis used chi-square tests and Poisson regression within a “multiple jeopardy” framework.
Compared with white men with high educational attainment, Black, Brown, Asian, and Indigenous women with low educational attainment had a four-fold higher probability of reporting both conditions, a three-fold higher probability of diabetes, and a 2.3-fold higher probability of hypertension. Low educational attainment was associated with higher prevalence of all three outcomes across sex and race/color groups. The authors estimated that low educational attainment was attributable to 34.6% of diabetes cases, 21.6% of hypertension cases, and 44.2% of cases involving both conditions.
These findings describe associations in a Brazilian population and rely on self-reported diagnoses; the cross-sectional design does not establish that educational attainment caused the conditions. The authors argue that prevention and control policies should address structural vulnerabilities.
