title: Comparison of two instruments to track depression symptoms during pregnancy in a sample of pregnant teenagers in Southern Brazil.
abstract: BACKGROUND
  Depression during pregnancy in adolescents is increasing significantly. However, instruments for early depression screening during prenatal care are scarce. Faced this fact, the objective of this research is to identify the best cutoff points for the Edinburgh Postnatal Depression Scale (EPDS) and Beck Depression Inventory (BDI) in a sample of pregnant adolescents.
  
  
  METHODS
  807 pregnant adolescents, with a mean age of 17 years, met in public antenatal services were evaluated. Two screening scales for depression were analyzed, EPDS and the BDI. These scales had their accuracy measured by AUC of their ROC curve, as well as their respective sensitivity and specificity.
  
  
  RESULTS
  In the analysis, the best cutoff for the EPDS was≥10, in which the sensitivity was 81.1% and specificity 82.7%. For the BDI, it was with recognized the cutoff ≥11, sensitivity 86.7% and specificity 73.8%. In the analysis of the ROC AUC, values of 0.89 (CI 0.87-0.92) for the EPDS and BDI for 0.87 (CI 0.84-0.89) were identified compared to the MINI.
  
  
  CONCLUSIONS
  The sample was composed majority by middle and low income adolescent and the study was performed only with pregnant women in the second trimester.
  
  
  CONCLUSIONS
  The results indicate that both scales have good accuracy in screening of depression in adolescent mothers. However, the EPDS scale shows higher AUC ROC and also better sensitivity and specificity values, the latter being more precise and effective for screening for depression in this population.
