title: Depression in teenager pregnant women in a public hospital in a northern mexican city: prevalence and correlates.
abstract: BACKGROUND
  Very little is known about prenatal depression in teenagers in Mexico. We determined the prevalence and correlates of prenatal depression in teenager women attending a public hospital in Durango City, Mexico.
  
  
  METHODS
  We performed a cross-sectional study to assess depression in 181 teenager pregnant women who attended a public hospital for prenatal care. We used a validated Mexican version of the Edinburg postnatal depression scale (EPDS) to screen depression. Women with EPDS scores suggestive of depression were further examined to confirm depression by a psychiatric evaluation using the DSM-IV criteria. Bivariate and multivariate analyses were used to evaluate the prevalence association with socio-demographic, clinical and psychosocial characteristics of the pregnant women.
  
  
  RESULTS
  Of the 181 teenager pregnant women studied, 61 (33.7%) had EPDS equal to or higher than 8 (range 8 - 23), and 37 of them were confirmed to have prenatal depression by the psychiatric evaluation. The general prevalence of prenatal depression in the teenager pregnant women studied was 20.4%. Of the 37 women with depression, 34 suffered from minor depression and three suffered from major depression. Thus, the prevalence of minor and major depression in the women studied was 18.8% and 1.7%, respectively. Multivariate analysis of the socio-demographic, clinical and psychosocial characteristics of the teenager pregnant women showed that prenatal depression was associated with a previous episode of depression during pregnancy (odds ratio (OR) = 6.12; 95% confidence interval (CI): 1.68 - 22.30; P = 0.006), and borderline associations with big fetal size (OR = 9.9; 95% CI: 0.94 - 104.24; P = 0.05) and family problems (OR = 3.83; 95% CI: 0.99 - 14.84; P = 0.05).
  
  
  CONCLUSIONS
  Results demonstrate that prenatal depression is common in pregnant teenagers in Durango City, Mexico. The history of an episode of depression during pregnancy should alert physicians for further depression episodes during pregnancy in teenagers. Further research to elucidate the association of prenatal depression with size of the fetus and family problems in pregnant teenagers is needed.
