The prevalence of perinatal depression and its associated factors in two different settings in Brazil

Background evalence of antepartum and postpartum depression (PPD) and its association with certain risk factors was evaluated. inburgh Postnatal Depression Scale (EPDS) was applied and sociodemographic data was obtained at the beginning of the third trimester of pregnancy and at 4–6 weeks postpartum. s evalence of depression was 24.3% during pregnancy (n = 600 women) and 10.8% in the postpartum period (n = 555). The factors independently associated with antepartum depression were the absence of a partner (PRadj 1.93; 95%CI: 1.44–2.58), a lower socioeconomic class (1.75; 1.18–2.60), being non-white (1.48; 1.09–2.01) and multiparity (1.32; 1.01–1.74). For postpartum depression, the factors were the occurrence of psychological violence (PRadj 3.31; 95%CI: 2.02–5.43), use of alcohol during pregnancy (2.14; 1.33–3.45), being non-white (1.85; 1.11–3.08) and physical violence (2.14; 1.13–4.08). The sensitivity of depression during pregnancy as a predictor of PPD was 75%, while specificity was 81%. There were no differences between the two settings. tions oes not diagnose depression and as a screening instrument it could overestimate the true prevalence of depression. sions e of the EPDS instrument during pregnancy would allow a screening for identifying women at higher risk of developing PPD and then a proposal of specific interventions to manage this condition. Postpartum depression was prevalent in around 10% of the women and was associated with unfavorable sociodemographic conditions including the use of alcohol and with the occurrence of psychological and physical violence.
