To examine the association between exposure to acid-suppressive medications during pregnancy and the incident risk of pediatric-onset inflammatory bowel disease (IBD).
Approach:
Study Design: A nationwide, population-based birth cohort study in South Korea, including nearly 3 million mother-child pairs born from January 1, 2009, to December 31, 2023.
Data Collection: Utilized data from the National Health Insurance Service (NHIS) covering demographic, diagnostic, procedural, and medication records.
Cohort Selection: Excluded individuals with specific health conditions and those without recorded exposure to acid-suppressive medications during pregnancy.
Outcome Definition: Primary outcome defined as the diagnosis of any IBD (ulcerative colitis or Crohn disease) identified via ICD-10 codes.
Statistical Analysis: Used propensity score matching to minimize confounding between exposed and unexposed groups.
Key Findings:
Prenatal exposure to acid-suppressive medications may alter gut microbial composition.
Interpretation:
Limitations:
The study relies on administrative data, which may have limitations in accuracy.
Potential confounding factors may still exist despite propensity score matching.
Conclusion:
Further research is needed to clarify the relationship between prenatal acid-suppressive medication use and pediatric IBD risk.
