BACKGROUND: To determine whether changes in anxiety and depression during pregnancy influence the risk of having a preterm birth (PTB), and whether chronic stress modifies this relationship.
METHODS: The data source for the current study is the All Our Babies prospective cohort (AOB). Anxiety and depression were measured at 17-24 weeks and again at 32-36 weeks' gestation using the Spielberg State Anxiety Scale and the Edinburgh Postnatal Depression Scale, respectively. Chronic stress was assessed at 17-24 weeks' gestation as a potential covariate, and was measured using the Perceived Stress Scale. Multivariable logistic regression modeling was used to assess each relationship RESULTS: Women who experienced an increase in anxiety scores, (time point 32-36 weeks, compared to the earlier time point 17-24 weeks), had 2.70 times higher odds of preterm delivery, compared to those with a reduction in anxiety scores (95% CI 1.28, 5.69). Consistent low or high depression scores did not significantly influence the odds of PTB compared to a decrease in depression scores. A co-occurring increase in anxiety and depression scores was not found to increase the risk of PTB, and chronic stress did not modify any of these relationships.
LIMITATIONS: This study was limited by a relatively small sample of women who delivered preterm, and therefore it was not possible to conduct additional analyses. Further, the analyses were limited to mostly late preterm infants (32-36 weeks' gestation).
CONCLUSIONS: These findings should be validated with additional cohorts and a larger sample size. Ultimately, primary prevention could address anxiety during pregnancy.
