Clinical Report: Impact of Maternal Intellectual and Developmental Disabilities on Infant Health Outcomes
Overview
This study investigates the associations between maternal intellectual and developmental disabilities (IDDs) and adverse infant health outcomes, including preterm birth and NICU admissions. It highlights significant risks associated with various IDD subtypes and emphasizes the need for targeted interventions.
Background
Intellectual and developmental disabilities (IDDs) affect approximately 1% to 2% of the population and are linked to poorer health outcomes during pregnancy. Previous studies have indicated increased risks of adverse birth outcomes for infants born to mothers with IDDs, but limitations in these studies have hindered clinical application. Understanding these associations is crucial for improving maternal and infant health care.

Key Findings
Maternal IDDs are associated with a 50% to 80% increased risk of preterm birth and NICU admission.
Distinct IDD subtypes (ASD, ID, CP, chromosomal differences) were analyzed for their specific impacts on infant outcomes.
Previous studies aggregated IDD subtypes, potentially obscuring the true effects on infant health.
Causal mediation analyses were employed to estimate the proportion of excess risk associated with modifiable maternal characteristics.
The study utilized a comprehensive dataset from California, linking vital statistics with hospital records.
Clinical Implications
Healthcare providers should be aware of the increased risks associated with maternal IDDs and consider these factors when managing pregnancies. Targeted interventions may be necessary to address modifiable maternal characteristics that contribute to adverse infant outcomes.
Conclusion
The findings underscore the importance of understanding the impact of maternal IDDs on infant health outcomes, highlighting the need for tailored clinical approaches.
