Background:

Smoking increases the risk of diabetic complications, but the prevalence of smoking in diabetes is similar to non-diabetes. We aimed to investigate factors associated with smoking cessation intentions (SCI) in current smokers with diabetes.

 Methods:

In the 2013 Community Health Survey, information about current smokers has been collected among people who are over 30 years old with diabetes. Chi-squared test and logistic regression analysis were used to examine the association between socio-demographic indicators, health behaviors, comorbidities, smoking-related factors, diabetes-related factors and SCI. A total of 3,511 current smokers with diabetes were included in the final analysis.

 Results:

Among current smokers with diabetes, 13.4% reported having SCI (within six months). In multivariate logistic regression analysis, gender, education, marital status and occupation were found to be significantly related to SCI. Moreover, lower amounts of smoking, previous attempts to smoking cessation (odds ratio [OR] 3.66, 95% confidence interval [CI] 2.94-4.56), experience of smoking cessation recommendations from acquaintances (OR 1.87, 95% CI 1.38-2.52), experience of smoking cessation education (OR 1.57, 95% CI 1.12-2.20), and experience of diabetic education (OR 1.33, 95% CI 1.06-1.66) were significantly associated with SCI in current smokers with diabetes.

 Conclusion:

In order to lower the smoking rate of community-dwelling adults with diabetes, effective anti-smoking interventions are needed, taking into account SCI-related factors, including smoking cessation education and diabetes education.
