Background and AimSmoking cessation is known to improve the course of Crohn's disease (CD). However, the factors associated with smoking cessation after CD diagnosis have not been well established.
MethodsClinical characteristics and change in smoking status were evaluated in 445 current smokers at the time of CD diagnosis. Patients were classified into three subgroups based on their final smoking status and time of smoking cessation: non-quitters, quitters at diagnosis, and quitters during follow-up.
ResultsThe overall smoking cessation rate was 55.7% (248 of 445 patients). The diagnosis of CD was the main reason for quitting (41.5%, 103 of 248 patients). Smoking cessation at the time of CD diagnosis was associated with intestinal resection within 3months from CD diagnosis (odds ratio [OR] 2.355, 95% confidence interval [CI] 1.348-4.116, P=0.003), light smoking (OR 2.041, 95% CI 1.157-3.602, P=0.014), and initiation of smoking before 18years of age (OR 0.570, 95% CI 0.327-0.994, P=0.047). Light smoking (OR 1.762, 95% CI 1.019-3.144, P=0.043) and initiation of smoking before 18years (OR 0.588, 95% CI 0.381-0.908, P=0.017) were also associated with overall smoking cessation.
ConclusionQuitters after CD diagnosis, including quitters at diagnosis and quitters during follow-up, had features distinct from those of non-quitters. Given the motivation at CD diagnosis, a detailed history of smoking habits should be taken and all current smokers should be encouraged to quit smoking at the time of CD diagnosis.
