The effects of prenatal exposure to opioids on early childhood development: context matters most.

Introduction: The opioid crisis has brought an increasing focus on the long-term outcomes of children following prenatal opioid exposure. Evidence to date has been conflicting, which has caused confusion and concern amongst parents, caregivers, social service providers, medical providers and policy makers.

Methods: This review systematically evaluated the highest quality studies relating prenatal exposure to opioids with early childhood developmental outcomes. It focused on developmental outcomes as measured by the Bayley Scales of Infant and Toddler Development, encompassing cognitive, motor, and psychosocial domains of child development.

Results: Although several articles reported correlations between prenatal opioid exposure and poor early childhood developmental outcomes, these relationships were no longer statistically significant after adjusting for socio-environmental factors.

Conclusion: Additional research is needed to determine the extent of any relationship of socio-environmental factors with early childhood development in children prenatally exposed to opioids. This review suggests that socio-environmental factors may be significantly related to poor early childhood outcomes in the presence of prenatal opioid exposure.
