Receiving a doctor’s advice to quit smoking is an important predictor for improving smokers’ intentions to quit smoking and successful smoking cessation. We examined reports of smokers with Crohn’s Disease (CD) and Ulcerative Colitis (UC) regarding receiving a doctor’s advice to quit smoking in the past 12 months, and eval-uated the differences in the rates of receiving the advice between the CD and UC patients. The data were retrospectively reported by CD and UC patients (n = 453) who self-identified as current smokers in online assessments conducted by IBD Partners in the period from 2011 to 2014 in the USA. Statistical methods included chi-square tests and a multiple logistic regression model for the logit of the probability of receiving the advice as a function of patient’s characteristics and assessment year. Overall, about 77% of smokers reported receiving a doctor’s advice to quit smoking. The percentage was significantly (p < 0.001) higher among smokers with CD (80%) than it was among smokers with UC (63%). While the specificdifferences by CD/UC depended on smoking initiation age, the overall effect of disease type on the odds of receiving the advice remained significant: the odds of receiving the advice were higher for smokers with CD relative to smokers with UC (OR = 3.6, p < 0.001). Although the majority of CD and UC patients report receiving a doctor’s advice to quit smoking, the encountered difference associated with the disease type is concerning. Because long-term smoking increases cancer and mortality risks, doctors should address smoking cessation with all patients who smoke.
