Introduction: A link between inflammatory bowel disease (IBD), stressful life events, and psychological factors has previously been reported. Our objective was to examine the relationship between emotional, physical, and sexual abuse of childhood and risk of IBD using a large cohort of female health professionals.
Methods: We included participants in the Nurses' Health Study II who completed the Physical and Emotional Abuse Subscale of the Childhood Trauma Questionnaire and the Sexual Maltreatment Scale of the Parent-Child Conflict Tactics Scale in 2001. Diagnosis of IBD was determined by self-report and confirmed independently by 2 physicians through review of medical records. We used Cox proportional hazard modeling to estimate the risk of Crohn's disease (CD) and ulcerative colitis (UC) while adjusting for covariates.
Results: Among 68,167 women followed from 1989 until 2017, there were 146 incident cases of CD and 215 incident cases of UC. Compared with women with no history of abuse, the adjusted hazard ratios of CD were 1.16 (95% confidence interval [CI] 0.67-2.02) for mild, 1.58 (95% CI 0.92-2.69) for moderate, and 1.95 (95% CI 1.22-3.10) for severe abuse ( Ptrend = 0.002). We did not observe an association between childhood abuse and risk of UC.
Discussion: Women who reported early life severe abuse had an increased risk of CD. These data add to the growing body of evidence on the critical role of early life stressors in development of CD.
