Prevalência de diabetes mellitus e fatores associados na população adulta brasileira: Evidências de um inquérito de base populacional

Abstract

Objective: To estimate the prevalence of self-reported diabetes mellitus (DM) and its associated factors among the Brazilian adult population. Methods: The prevalence of DM was assessed in the Survey on Social Dimensions of Inequalities, a national survey with macro-regions representativeness carried out in 2008. Data were collected by a personal face-to-face interview with 12,423 individuals of both sexes, aged over 20 years. The χ2 test at 5.0% was performed in order to identify associated factors, and logistic regression was used to estimate adjusted odds ratios. Results: The prevalence of DM in Brazil was 7.5%. After adjusting for potential confounders, diabetes remained associated with age (≥ 40 years), education (< 8 years of study), marital status (non-married), obesity, sedentary lifestyle, comorbidity with hypertension and hypercholesterolemia, as well as the demand for health services. Conclusion: Results indicate a high prevalence of DM and its associated preventable factors in Brazil. Thus, they highlight the need for a behavioral change as a strategy for prevention and control of diabetes and its complications.
