A survey is conducted on patients with inflammatory bowel disease (IBD). Current smoking status, daily smoking amount, smoking period, perception of smoking effect on the induction of Crohn's disease (CD) or ulcerative colitis (UC), and perception of the effect of smoking on the course of CD or UC were investigated. Moreover, the intention to quit smoking is investigated. After the survey, information on the effects of smoking on CD or IBD is provided, and smoking cessation education is provided. After three months, the patients' smoking behavior was investigated, and the smoking cessation rate was investigated.
This study will investigate the perception of the relationship between smoking and inflammatory bowel disease by surveying inflammatory bowel disease patients. Afterward, the relationship between smoking and inflammatory bowel disease will be explained, and the smoking cessation rate will be investigated three months later.
