A smoking cessation intervention among tuberculosis patients in rural China

OBJECTIVE: To assess the integration of a smoking cessation intervention into routine tuberculosis (TB) services.

METHOD: Consecutive TB patients registered from 1 March to 31 August 2010 were enrolled in an intervention for self-reported smoking to promote tobacco cessation during treatment for TB. Information on the harmful health effects of tobacco smoke and smoking and TB were provided to TB patients who self-reported as current smokers. Smoking status was reassessed at every follow-up visit during anti-tuberculosis treatment with reinforced health messages and advice to quit.

RESULTS: Of 800 TB patients enrolled, 572 (71.5%) were male and 244 (30.5%) were current smokers. Females were more likely to be non-smokers (100% vs. 35.8%, P < 0.001). Of the 244 current smokers, 144 (59.0%) started smoking at <20 years, 197 (80.7%) consumed ⩾20 cigarettes per day, 211 (86.5%) had perceived smoking dependence and 199 (81.6%) had made no attempt to quit before the diagnosis of TB. Of the 244 current smokers, 234 (95.9%) were willing to quit, and 156 (66.7%) reported abstinence at month 6. Challenges to implementing smoking cessation intervention were identified.

CONCLUSION: The majority of current smokers among TB patients were willing to quit and remained abstinent at the end of anti-tuberculosis treatment. This intervention should be scaled up nationwide.
