MONDAY, June 12, 2017 (HealthDay News) -- For patients with Crohn's disease (CD), smoking cessation at the time of diagnosis is positively associated with intestinal resection within three months and light smoking, according to a study published online May 26 in the Journal of Gastroenterology and Hepatology.

Eun Mi Song, from the University of Ulsan College of Medicine in Seoul, South Korea, and colleagues examined clinical characteristics and change in smoking status in 445 current smokers at the time of CD diagnosis. Patients were categorized based on their final smoking status and time of smoking cessation.

The researchers observed an overall smoking cessation rate of 55.7 percent. CD diagnosis was the main reason for quitting (41.5 percent). Cessation of smoking at the time of CD diagnosis correlated with intestinal resection within three months of diagnosis (odds ratio, 2.355), light smoking (odds ratio, 2.041), and with smoking initiation before 18 years of age (odds ratio, 0.570). There were also correlations for light smoking (odds ratio, 1.762) and initiation of smoking before 18 years (odds ratio, 0.588) with overall smoking cessation.

"Quitters after CD diagnosis, including quitters at diagnosis and quitters during follow-up, had features distinct from those of non-quitters," the authors write. "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."
