Prenatal Opioid Exposure Linked to Increased Childhood Hospital Admissions
According to Medical Xpress, a large South Korean study found that children whose mothers received opioid prescriptions during pregnancy had higher rates of hospital admission in childhood.
For families navigating pain treatment during pregnancy, the finding is a reason to discuss medication choices and follow-up plans carefully, not evidence that a prescription will cause harm to a particular child.
What the study found
Researchers used national health insurance data to follow 2,928,186 children born in South Korea between 2010 and 2017, for up to 14 years. They counted a pregnancy as opioid-exposed when the mother received at least two prescriptions.
Compared with children without recorded prenatal exposure, exposed children had a 28% higher rate of hospital admission. The association was smaller when researchers compared siblings from the same family: the rate was 8% higher. The study also reported higher admission rates with higher maternal opioid doses, and the strongest association was among children up to age five.
Admissions covered several causes, including infections and respiratory, gastrointestinal and genitourinary conditions. These findings describe associations across a population; they cannot predict an individual child’s health.
How to use this information in care
The sibling comparison matters because it suggests that factors shared within families may account for some of the observed difference. The researchers also cautioned that prescription records do not show whether a medication was actually taken, and that other unmeasured family factors may remain relevant. The study therefore does not establish that opioid prescriptions caused the admissions.
If you are pregnant and taking, or being offered, an opioid, bring your full medication list and ask your clinician to review the reason for treatment, the dose and duration, and whether other options are appropriate for your situation. Do not stop or change a prescribed medication without discussing it with your care team.
A practical next question is: what follow-up, if any, should we plan for the baby after birth, given my medication history and the reason it was prescribed?
