Objective: To determine the prevalence of depression in a community with 15 000 inhabitants in Brazil (Bambuí). Method: The Composite International Diagnostic Interview was applied in a random sample of 1041 residents aged 18+ years. Results: The ICD‐10 1‐month, 1‐year and lifetime prevalences of depression were 8.2% (95% CI:6.5–9.8), 10.0% (95% CI:8.2–11.8) and 15.6% (95% CI:13.4–17.8), respectively. Kappa coefficients comparing ICD‐10 and DSM‐III‐R diagnoses were high (0.73–0.79). Female sex (OR=2.4; 95% CI:1.3–4.2), age 45–59 years (OR=3.5; 95% CI:1.7–7.2) and 60 years (OR=4.0; 95% CI:1.9–8.5) and being out of work (OR=2.1; 95% CI:1.2–3.6) were independently and positively associated with 1‐month depression. Conclusion: The 1‐month prevalence of depression was higher than that observed in similar studies in developed and developing countries. Depression may be a major unidentified disease of people living in small communities of Brazil and other developing countries, especially among older women.
