Study description

Approximately, 10-20% of pregnant women suffer from depression and 4-10% use selective serotonin reuptake inhibitor (SSRI) antidepressants at some stage during pregnancy. There is conflicting evidence regarding the risk of congenital anomalies and long-term neurodevelopmental outcomes such as autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) associated with in utero exposure to SSRI and serotonin and norepinephrine reuptake inhibitors (SNRI). Existing studies in the literature often lack the power to assess the effect of time varying confounders such as variation in maternal disease status, breastfeeding, and transient or chronic interactions with other medications on risk of adverse outcomes, and few examine other aspects of neurodevelopment. This study will help create evidence-based clinical guidelines on risks and benefits of antidepressant treatment in pregnancy. The objectives of this study are: 1) to develop algorithms to identify and validate maternal depression, neurodevelopmental outcomes and breastfeeding in healthcare data sources. 2) to describe patterns of SSRI/ SNRI antidepressant use before, during, and after pregnancy and during lactation. This includes describing co-medication patterns, predictors of discontinuation, switching patterns, and trajectories of use over time. 3) to assess the association between in utero exposure to SSRI / SNRIs and neurodevelopmental outcomes. It will examine the potential additional impact of maternal depression, breastfeeding and concomitant exposure to P-glycoprotein (P-gp) or breast cancer resistance protein (BCRP) transporter inhibitors/substrates on neurodevelopmental outcomes in children. A second objective is to perform a EUROmediCAT safety study to assess the risk of major congenital anomalies associated with exposure to SSRI / SNRIs in the first trimester of pregnancy, and to evaluate the impact of co-medication with P-gp or BCRP transporter substrates on risk.
