Prevalence of tobacco use and effectiveness of physician’s brief advice on tobacco cessation in the context of type 2 diabetes mellitus outpatients: A cross-sectional study

A history of tobacco use needs to be asked to all type 2 diabetes mellitus (DM) patients in each visit, documenting it, explaining the importance of quitting tobacco in the context of diabetes, and advising to quit tobacco, even to elderly patients. If all the physicians in the health system offer quit advice to all the tobacco users, many patients are likely to quit tobacco.
