[Depression in former slave communities in Brazil: screening and associated factors].

OBJECTIVE

To assess the prevalence and the factors associated with positive screening for major depressive episode (MDE) in former slave communities in the state of Bahia, Brazil.

METHODS

In this population-based, cross-sectional study, 764 participants were randomly selected from five former slave communities in Vitória da Conquista, Bahia, Brazil. Depression was defined as a cutoff score of 10 or more points and the presence of five or more symptoms according to the Patient Health Questionnaire (PHQ-9). Poisson regression was used to assess prevalence ratios (PR), with a 95% confidence interval (95%CI).

RESULTS

Screening for MDE was positive in 12% of participants (95%CI: 10 - 14%), but only 2.3% reported a previous diagnosis. Depression was associated with self-reported poor or very poor health status (PR = 1.14; 95%CI: 1.04 - 1.26), chronic disease (PR = 1.08; 95%CI: 1.04 - 1.13), no physical activity (PR = 1.06; 95%CI: 1.01 - 1.11), and reasonable (PR = 1.07; 95%CI: 1.01 - 1.13) or poor access to health services (PR = 1.07; 95%CI: 1.02 - 1.12).

CONCLUSIONS

The prevalence of MDE in this population was similar to that of the general Brazilian population. The association between MDE and poor access to health services indicates a missed opportunity for early diagnosis. Public measures against social and health inequalities are necessary to ensure equity in these communities.
