Anxiety and depression during pregnancy in Central America: a cross-sectional study among pregnant women in the developing country Nicaragua.

BACKGROUND: Around the world, maternal psychopathology during pregnancy is associated with a range of negative consequences for mother and child. Nevertheless, in Central America the magnitude of this public health problem is still unknown. The objective of this first explorative study was to investigate the prevalence and severity of anxiety and depression during pregnancy in the Central American developing country Nicaragua, as well as the availability of mental health care and to compare with a developed country. METHODS: A population-based cohort of pregnant women in Nicaragua (N = 98) was compared with a parallel cohort in the Netherlands (N = 4725) on symptoms of anxiety (Spielberger State Trait Anxiety Inventory) and depression (Edinburgh Postnatal Depression Scale). Associations with the women's knowledge how to reach professional psychological support were assessed using multivariable linear regression analyses. RESULTS: Of the Nicaraguan women, 41 % had symptoms of anxiety and 57 % symptoms of depression, versus 15 % and 6 % of the Dutch women. Symptom scores of both anxiety and depression were significantly higher in Nicaragua (p < 0.001). However, only 9.6 % of the women indicated that professional psychological help was available for the Nicaraguan pregnant women, which was associated with an increased anxiety score. CONCLUSIONS: In Nicaragua, both prevalence and severity of symptoms of antenatal anxiety and depression are substantially higher than in developed countries. However, availability of psychological help is very limited for pregnant Nicaraguan women. These findings indicate that there is need for further research and support for these women, to prevent negative consequences for both mother and child.

Predictive accuracy of Edinburgh postnatal depression scale assessment during pregnancy for the risk of developing postpartum depressive symptoms: a prospective cohort study.

OBJECTIVE: To investigate whether the 10-item Edinburgh Postnatal Depression Scale (EPDS) administered antenatally is accurate in predicting postpartum depressive symptoms, and whether a two-item EPDS has similar predictive accuracy. DESIGN: Prospective cohort study. SETTING: Obstetric care in the Netherlands. POPULATION: One thousand six hundred and twenty women from the general population. METHODS: Mean values, area under the receiver operating characteristics curve (AUC), sensitivity, specificity and predictive values of antenatal EPDS for the likelihood of developing postpartum depressive symptoms were calculated. Analyses were repeated for each trimester, several cut-off values and a two-item EPDS (low mood and anhedonia). MAIN OUTCOME MEASURES: Postpartum depressive symptoms, defined as EPDS score≥10. RESULTS: Mean EPDS scores were significantly higher during each trimester in women with postpartum depressive symptoms than in those without the symptoms (P<0.001). Using the prevailing cut-off (≥13), the AUC was reasonable (0.74), sensitivity was 16.8% (95% CI 11.0-24.1), positive predictive value was 41.8% (95% CI 28.7-55.9), specificity was 97.8% (95% CI 97.0-98.5) and negative predictive value was 92.7% (95% CI 91.3-94.0). Using a lower cut-off value (≥5), sensitivity was 70.8% (95% CI 62.4-78.3) and specificity was 65.4% 4 (95% CI 62.9-67.8), but positive predictive value was low (15.9%, 95% CI 13.1-19.0). Negative predictive value was exceedingly high at 96.0% (95% CI 94.6-97.2). Results were similar during the second and third trimester. The predictive accuracy of the two-item EPDS appeared inferior. CONCLUSIONS: The EPDS was not sufficiently accurate in predicting risk of postpartum depressive symptoms. Nevertheless, when using the ≥5 cut-off value, it may be adequate for initial screening, followed by further assessments and possibly antenatal intervention when positive. Furthermore, when negative, women may be reassured that postpartum depressive symptoms are unlikely. A two-item version showed poor predictive accuracy.
