Insights
ADHD medication use during pregnancy did not increase offspring
Area of Science:
- Neurodevelopmental Psychiatry
- Pediatric Pharmacology
- Pregnancy and Obstetrics
Background:
- Attention Deficit Hyperactivity Disorder (ADHD) medication use is rising during pregnancy.
- Concerns exist regarding potential long-term adverse effects of prenatal ADHD medication exposure on offspring development.
- Understanding these risks is crucial for maternal and child health management.
Purpose of the Study:
- To investigate the association between in utero exposure to ADHD medication and long-term neurodevelopmental and growth outcomes in offspring.
- To provide evidence-based information for pregnant individuals with ADHD considering medication continuation.
- To assess risks for neurodevelopmental disorders, sensory impairments, epilepsy, and growth issues.
Main Methods:
- A large-scale, population-based cohort study using Danish national registers.
- Inclusion of 1,068,073 liveborn singletons (1998-2015), followed until 2018.
- Comparison of offspring exposed to ADHD medication during pregnancy versus those whose mothers discontinued medication before pregnancy, using Cox regression analysis.
Main Results:
- No increased risk of combined offspring developmental disorders was found (aHR 0.97, 95% CI 0.81 to 1.17) after adjusting for maternal characteristics.
- Separate analyses for subcategories of outcomes and negative control/sibling-controlled analyses also showed no increased risk.
- Offspring neurodevelopment and growth did not differ based on antenatal exposure to ADHD medication.
Conclusions:
- Prenatal exposure to ADHD medication is not associated with adverse long-term neurodevelopmental or growth outcomes in offspring.
- Findings offer reassurance to women with ADHD who require medication for daily functioning and are pregnant.
- Continued ADHD medication use during pregnancy appears safe concerning offspring neurodevelopment and growth.
Abstract:
Attention Deficit Hyperactivity Disorder (ADHD) medication is increasingly being used during pregnancy. Concerns have been raised as to whether ADHD medication has long-term adverse effects on the offspring. The authors investigated whether in utero exposure to ADHD medication was associated with adverse long-term neurodevelopmental and growth outcomes in offspring. The population-based cohort study in the Danish national registers included 1,068,073 liveborn singletons from 1998 to 2015 followed until any developmental diagnosis, death, emigration, or December 31, 2018. Children of mothers who continued ADHD medication (methylphenidate, amphetamine, dexamphetamine, lisdexamphetamine, modafinil, atomoxetine, clonidine) during pregnancy and children of mothers who discontinued ADHD medication before pregnancy were compared using Cox regression. Main outcomes were neurodevelopmental psychiatric disorders, impairments in vision or hearing, epilepsy, seizures, or growth impairment during childhood or adolescence. In total, 898 children were exposed to ADHD medication during pregnancy compared to 1270 children whose mothers discontinued ADHD medication before pregnancy. After adjustment for demographic and psychiatric characteristics of the mother, no increased risk of any offspring developmental disorders was found combined (aHR 0.97, 95% CI 0.81 to 1.17) or for separate subcategories. Similarly, no increased risk was found for any sub-categories of outcomes in the negative control or sibling controlled analyses. Neurodevelopment and growth in offspring do not differ based on antenatal exposure to ADHD medication. These findings provide reassurance for women with ADHD who depend on ADHD medication for daily functioning and who consider continuing medication in pregnancy.
