Abstract

This dissertation refers to an epidemiological study of screening scales for depression in pregnant adolescents. The main objective of the research was to adjust the cutoff scales for screening for depression, Edinburgh Postnatal Depression Scale (EPDS) and Beck Depression Inventory (BDI), for pregnant teenagers. It is a cross-sectional, population-based study carried out with pregnant adolescents (10-19 years old), which consulted the service prenatal Unified Health System (SUS) of Pelotas. Was carried out from October 2009 to March 2011. The sample was composed based on the SIS-Prenatal program records along the municipal health department and the Basic Health Units, and specialized clinics in the urban area of Pelotas / RS. The women answered a questionnaire with socio demographic and obstetric data, besides the two scales for screening for depression during pregnancy. Also participated in a structured clinical interview Mini International Neuropsychiatric Interview 5.0 (MINI) for the clinical diagnosis of depression. Demographic, obstetric and psychiatric social variables were assessed according to the WHO questionnaire. The accuracy of the scales was calculated by their Area under the curve (AUC) of ROC, as well as their respective sensitivity, specificity and predictive values. The best cutoff (PC) found for this sample was ≥10 EPDS scale, with sensitivity 81.1% and specificity 82.7% and AUC of 0.899. BDI for the best cutoff point was ≥11, sensitivity 81.1%, sensitivity 76.8% and an AUC of 0.869. Since the difference between the two AUC were statistically significant (p = 0, 0215). Based on the results, it is concluded that the EPDS scale has become more predictive and sensitive in screening for depression in pregnant adolescents, with respect to BDI.
