摘要

AIM To investigate the differences in family history of inflammatory bowel disease(IBD) and clinical outcomes among individuals with Crohn’s disease(CD) residing in China and the United States.METHODS We performed a survey-based cross-sectional study of participants with CD recruited from China and the United States.We compared the prevalence of IBD family history and history of ileal involvement,CD-related surgeries and IBD medications in China and the United States,adjusting for potential confounders.RESULTS We recruited 49 participants from China and 145 from the United States.The prevalence of family history of IBD was significantly lower in China compared with the United States(China:4.1%,United States:39.3%).The three most commonly affected types of relatives were cousin,sibling,and parent in the United States compared with child and sibling in China.Ileal involvement(China:63.3%,United States:63.5%) and surgery for CD(China:51.0%,United States:49.7%) were nearly equivalent in the two countries.CONCLUSION The lower prevalence of familial clustering of IBD in China may suggest that the etiology of CD is less attributed to genetic background or a family-shared environment compared with the United States.Despite the potential difference in etiology,surgery and ileal involvement were similar in the two countries.Examining the changes in family history during the continuing rise in IBD may provide further insight into the etiology of CD.
