The impact of prenatal care on pregnancy outcomes in women with depression

Abstract

Objective

Depression occurs in 7–13% of pregnant women and is associated with increased risk during pregnancy including increased rates of cesarean delivery, preterm birth, and preeclampsia. Prenatal care is thought to decrease adverse outcomes in pregnancy. This study aimed to examine how delayed access to prenatal care affects maternal and neonatal outcomes in a cohort of women suffering from depression.

Study design

This is a retrospective cohort study of linked vital statistics and hospital discharge data among singleton, non-anomalous births in California between 2005 and 2008 comparing outcomes of all women with depression who received prenatal care prior to the third trimester versus women with depression who received prenatal care only during the third trimester or none at all. Outcomes included birthweight, stillbirth, neonatal demise, preeclampsia, preterm delivery and infant death. Statistical methods for outcome analysis included chi-square and multivariate logistic regression, adjusting for statistically significant and biologically plausible coexisting risk factors such as age, parity, gestational age, ethnicity, socioeconomic status, and substance abuse.

Results

Of the 14,242 women with depression in our sample, those with no prenatal care prior to the third trimester of gestation had higher odds of stillbirth (7.50; 2.34–23.97), neonatal death (4.42; 1.14–17.18), preterm delivery before 32 weeks (2.13; 1.08–4.17), SGA <5% (1.76; 1.10–2.81) and severe preeclampsia (1.92; 1.03–13.58).

Conclusion

In women with depression during pregnancy, receiving late or no prenatal care prior to the third trimester of pregnancy is associated with greater odds of neonatal and maternal morbidities, as well as, greater odds of fetal and neonatal mortality.
