Cure8 research brief
Parents and clinicians may wonder whether stressful events in early life increase a child’s long-term IBD risk. This large prospective study found no evidence that the measured early maternal or family adverse events raise later IBD risk, which may be reassuring.
Parents-caregivers, pediatric-patients, pediatric gastroenterologists, researchers interested in developmental risk factors for IBD.
This study pooled two large Scandinavian birth cohorts to ask whether early-life adverse family events (maternal adversity during pregnancy, and adverse family events by ages 1 and 3) are linked to later risk of developing IBD.
The authors followed 111,293 children using questionnaire reports of adverse events and national patient registries, identifying 697 IBD diagnoses over long follow-up, and found no association between these early adverse events and future IBD.
The analysis adjusted for parental and child characteristics and combined cohort-specific estimates with a random-effects model.
Reported adjusted hazard ratios for maternal adverse events in pregnancy and for adverse family events by age 1 or 3 were near 1.0 with confidence intervals that included the null, supporting a lack of evidence for increased IBD risk from these measured early-life stressors.
These results address a specific hypothesis about early-life psychosocial adversity imprinting immunological pathways relevant to IBD; they do not rule out other environmental, genetic, or later-life exposures that could influence risk.
The summary is based on the article abstract (structured content depth: abstract). Adverse events were self-reported in cohort questionnaires and IBD cases were identified through national patient registers; findings apply to the exposures, populations, and methods used and do not exclude other risk factors or later-life influences.
