Course of depressive symptoms across pregnancy in African American women

INTRODUCTION

Although African American women are at increased risk for antenatal depression, less is known regarding the course of antenatal depression symptoms among African American women. Because pregnancy is a state of rapid physical and mental changes, we examined if depression symptoms changed between the second and third trimesters in a sample of pregnant African American women.

METHODS

A nonprobability sample of women was recruited from obstetrics clinics within a large Midwestern health system. African American women in their second trimester (N = 189) completed an initial study visit; a convenience sample of 37 women (19.6%) completed a second identical study visit during their third trimester. The 20-item Center for Epidemiological Studies Depression Scale (CES-D) was used to measure depressive symptoms; a CES-D score of 16 or higher equates with clinical depression and a CES-D score of 23 or higher indicates major depression. Paired t tests and correlation coefficients were used to estimate change in depression symptoms.

RESULTS

Mean (SD) second- and third-trimester CES-D scores were not statistically significantly different (15.3 [10.6] and 15.1 [10.3], respectively; P = .87) and were moderately and significantly correlated (r = 0.65; P .001). Prevalence of CES-D scores of 16 or higher was 43.2% (n = 16) in the second trimester and 37.8% (n=14) in the third trimester, which was not significantly different (P =.77). Between the 2 visits, 67.6% (n=25) were classified identically with a CES-D scores of 16 or higher with only fair agreement between the 2 measures (kappa = 0.33). Prevalence of CES-D scores of 23 or higher was 27.0% (n = 10) and 21.6% (n = 8) in the second and third trimesters, respectively, and was not significantly different (P = .69). Between the 2 visits, 83.8% (n = 31) were classified identically with CES-D scores of 23 or higher, with moderate agreement between the 2 measures (kappa = 0.56).

DISCUSSION

Depression symptoms were relatively constant across the latter 2 trimesters of pregnancy. The second trimester may be an appropriate time to screen women for antenatal depression, as it is less likely to be affected by early-pregnancy somatic events yet is early enough that intervention may impart positive health benefits for mother and child.

Antenatal depressive symptoms and the risk of preeclampsia or operative deliveries: a meta-analysis

BACKGROUND

The purpose of the study was to investigate the association between depression and/or depressive symptoms during pregnancy and the risk of an operative delivery or preeclampsia, and to quantify the strength of the association.

METHODS

A search of the PubMed, SCI/SSCI, Proquest PsycARTICLES and CINAHL databases was supplemented by manual searches of bibliographies of key retrieved articles and review articles. We aimed to include case control or cohort studies that reported data on antenatal depression and /or depressive symptoms and the risk of an operative delivery and/or preeclampsia.

RESULTS

Twelve studies with self-reported screening instruments were eligible for inclusion with a total of 8400 participants. Seven articles that contained 4421 total participants reported the risk for an operative delivery, and five articles that contained 3979 total participants reported the risk for preeclampsia. The pooled analyses showed that both operative delivery and preeclampsia had a statistically significant association with antenatal depressive symptoms (RR = 1.24; 95% CI, 1.14 to 1.35, and OR = 1.63, 95% CI, 1.32 to 2.02, respectively). When the pre-pregnancy body mass indices were controlled in their initial design, the risk for preeclampsia still existed (OR = 1.48, 95% CI, 1.04 to 2.01), while the risk for an operative delivery became uncertain (RR = 1.01, 95% CI, 0.85 to 1.22).

CONCLUSIONS

Antenatal depressive symptoms are associated with a moderately increased risk of an operative delivery and preeclampsia. An abnormal pre-pregnancy body mass index may modify this association.

Antenatal depressive symptoms and preterm birth: a prospective study of a Swedish national sample

BACKGROUND

Preterm birth is the principal risk factor for neonatal morbidity and mortality. The objective of this study was to investigate the association between antenatal depressive symptoms and preterm birth.

METHODS

The study included a national sample of 2,904 pregnant women who were recruited at their first booked visit to antenatal clinics in Sweden. Data on depressive symptoms, and sociodemographic and reproductive background were collected by questionnaires. Depressive symptoms were assessed by the Edinburgh Postnatal Depression Scale (EPDS). The average length of gestation at the time for completion of the questionnaire was 16 weeks. Data on gestational length were extracted from the Swedish Medical Birth Register. Multiple logistic regression analyses were conducted to estimate the risk of preterm birth associated with antenatal depressive symptoms.

RESULTS

The presence of antenatal depressive symptoms above a cutoff score of 12 or higher on the EPDS increased the risk for preterm birth (OR: 1.56; 95% CI: 1.03-2.35). Being of age 35 years and over, being a primipara, and having experienced a previous miscarriage were also shown to be significant predictors in a multivariate model.

CONCLUSION

Pregnant women reporting antenatal depressive symptoms are at elevated risk of preterm birth.
