Factors Associated with Persistent Smoking in Diabetic Patients: The Seventh Korea National Health and Nutrition Examination Survey

ABSTRACT

Background@#Smoking increases total mortality and the risk of complications in patients with diabetes; however, smokers tend to smoke persistently even after the diagnosis of diabetes mellitus. The purpose of this study was to analyze risk factors predicting persistent smoking in Korean adults with diabetes. @*Methods@#This study included 265 persistent-smokers and 146 quit-smokers among the participants with diabetes from the seventh Korea National Health and Nutrition Examination Survey. The subjects were smokers at the time of diagnosis of diabetes and were categorized into two groups according to the change in smoking status between the time of diabetes diagnosis and survey. Factors associated with persistent smoking were evaluated using multiple logistic regression analysis. @*Results@#The prevalence of persistent-smokers with diabetes in this study was 65.3%. After adjusting for covariates, persistent smoking in Korean adults with diabetes was significantly associated with a history of cancer (adjusted odds ratio [aOR], 0.322; 95% confidence interval [CI], 0.116–0.889), strength exercise (aOR, 2.753; 95% CI, 1.361–5.566), stress (aOR, 2.036; 95% CI, 1.046–3.950), non-medical treatment for diabetes (aOR, 6.814; 95% CI, 1.661–27.957), and duration of diabetes (aOR, 0.952; 95% CI, 0.919–0.987). @*Conclusion@#Identifying the risk factors related to persistent smoking among Korean adults with diabetes can help in developing effective smoking cessation strategies.
