Neonatal outcomes of pregnant women attending integrated and standard substance use treatment programs in Ontario, Canada.

Findings underscore the need for more nuanced research that considers the influence of client factors in interaction with treatment type. Pregnant clients engaged in any form of substance use treatment are at higher risk of having children who experience adverse neonatal outcomes. This underscores the urgent need for further investment in services and research to support maternal and neonatal health before and during pregnancy, as well as long-term service models that support women and children beyond the perinatal and early childhood periods.
