BACKGROUND: Diabetes mellitus (DM) is a public health problem in Brazil. The objective of this study was to investigate the prevalence of DM and its relation with socio-demographic features and other cardiovascular risk factors in a adult population from the wilderness of Pernambuco, Brazil. SUBJECTS AND METHODS: In 2008/2009 a cross-sectional study in the adult urban population of Canãa district, city of Triunfo, in the wilderness of Pernambuco/Brazil was conducted. A representative sample of 198 individuals, with average age of 57.7 years, 80% with primary education and 81.3% with a monthly income of less than 1 minimum wage was randomly selected. RESULTS: A prevalence of diabetes of 13.6% and 7.6% of disglycemia (6.6% of impaired fasting glycemia, and 1.0% of impaired glucose tolerance) was found. Among those with diabetes, 24% had no prior diagnosis. Among diabetics, metabolic syndrome (MS) and arterial hypertension (AH) were diagnosed in 87.5% and 68%, respectively. Besides these, there was a positive and significant association between DM and BMI, and between DM and MS. CONCLUSION: These data demonstrate a high prevalence of DM in the adult urban population from the wilderness of Pernambuco/Brazil. These results as well as their association with obesity and MS, indicate that more effective interventions are necessary for the prevention of these diseases also outside principal urban centers.
