BACKGROUND: The association between antidepressant use during pregnancy and adverse perinatal outcomes is unclear. The association without taking into consideration the independent effect of depression leads to a confounding of the effects of antidepressants with those of the underlying reason for the use of those medications. Additionally, a history of depression and antidepressant use may also influence this association.
OBJECTIVE: This study examined the risks of adverse perinatal outcomes associated with antidepressant use during pregnancy.
METHODS: This retrospective cohort study used population-based data in Alberta, Canada, for women who delivered between 2012 and 2015 (n = 158486). Women with depression were identified using a validated case definition, and the receipt of antidepressants was identified using Anatomical Therapeutic Chemical codes. Adverse perinatal outcomes such as severe maternal/neonatal morbidity, preterm birth, and neonatal intensive care unit admission were assessed. Multivariable log-binomial regression was used to estimate the risk of adverse perinatal outcomes associated with antidepressants, adjusting for age and parity.
RESULTS: In total, 9.1% women had depression and 2.5% women received antidepressants during pregnancy. The relative risk of severe neonatal morbidity/mortality was 1.25 (95% confidence interval 1.17, 1.33) times higher for women with depression alone compared to women without depression. The risk of severe neonatal morbidity/mortality was 1.51 (95% confidence interval 1.36, 1.66) times higher for women who used antidepressants compared to women with depression alone-however, the risk differed between the women with and without a history of antidepressant use. A similar risk pattern was observed for preterm birth and neonatal intensive care unit admission.
CONCLUSIONS: Both depression and antidepressant use were independently associated with the risk of adverse perinatal outcomes; however, the risk associated with antidepressants was higher over and above the risk associated with depression. This may reflect the biological effects of antidepressants, greater severity of depression in those treated, or both.
