Smoking increases the risk of recurrent Crohn's disease (CD). It also increases the need for surgical treatment.
In this study, researchers from England and the United States assessed the awareness among patients with CD of the impact that smoking could have on their disease.
The team distributed self-administered questionnaires to 714 CD patients under follow-up at the University Hospital Birmingham, England.
They asked the patients 8 multiple-choice questions about the effects of smoking on health and on CD.
The researchers also collected data on relevant patient demographics, smoking history, and medical history.

A total of 312 patients completed the questionnaires.
The research team found that 92% of patients acknowledged the dangers of smoking on overall health. They found that 90% acknowledged lung cancer, 91 % lung disease, and 85% cardiovascular disease.
Furthermore, the team found that employed, educated, and home-owning patients were more aware of these smoking risks.
However, few patients recognized that smoking increased the risk of developing CD (10%), and of reoperation for CD (12%).
The research team determined that few patients recognized that both the quantity of cigarettes smoked (11%) and the duration of smoking (17%) increased the risk of reoperation.
Dr William Ryan's team concluded, "Patients with CD are unaware of the risks that smoking has on their disease, indicating a need for increased patient education with regard to the effects of smoking on CD".
