Tobacco smoking and diabetes. A comparative survey among diabetologists and smoking cessation specialists.

Aims: Because tobacco smoking is a major risk factor of mortality in diabetes and guidelines suggest evaluating smoking behavior among individuals with diabetes and helping smokers quit, we aimed to assess knowledge about the tobacco smoking - diabetes relationship among diabetologists and smoking cessation specialists (SCS).
Methods: An online cross sectional survey was conceived by the Working Group on Smoking and Diabetes, France. The questionnaire was tested by the members of the Working Group and deemed to be completed in less than 5 min. Only questions receiving the highest number of approval ratings were kept for the survey. The questionnaire was sent to all members of the French Language Society of Diabetes (Société Francophone du Diabète, SFD), N = 969 and the French Language Society on Tobacco (Société Francophone de Tabacologie, SFT), N = 307. The mailing lists of members were obtained with the previous agreement of the societies' board.
Results: 225 diabetologists and 97 SCS (response rate 23.2% and 31.5%, respectively) completed the questionnaire. Over 90% of the diabetologists reported recording smoking status of their patients. Although diabetologists were aware that smoking increases all-cause mortality of individuals with diabetes, only 29.3% were aware that smoking is a risk factor for type 2 diabetes (76.3% among SCS), for poor glycemic control: 32.9% (86.6% among SCS). Significantly less diabetologists (64%) than SCS (76.3%) were aware of smoking being a risk factor for microangiopathy. More diabetologists considered that smoking cessation is more important than optimizing glycemic control among individuals with type 2 (69.3%) than among those with type 1 diabetes (47.1%). Few diabetologists (11.1%) and SCS (14.4%) reported to be trained for smoking cessation among persons with diabetes.
Conclusion: Specific knowledge about the negative tobacco smoking - diabetes association seems to be insufficient among French diabetologists. Diabetologists but also other health care professionals should be trained to help individuals with diabetes who smoke to quit smoking.
