Factors That Predict Persistent Smoking of Cancer Survivors

ABSTRACT

We conducted this cross-sectional study to elucidate factors that predict persistent smoking of the Korean cancer survivors. The subjects were 130 adult (> or =19 yr old) cancer survivors who were smokers at the diagnosis of cancer and have participated in the Korean National Health and Nutrition Examination Surveys conducted from 2007 to 2011. We categorized them into the persistent smokers and the quitters, according to change in smoking status between the time of cancer diagnosis and the time of the survey. Factors associated with persistent smoking were evaluated using the multiple logistic regression analysis. During 7.52 yr (standard deviation = 0.34) after the cancer diagnosis, 59.6% of the 130 cancer survivors have continued to smoke. After adjusting for covariates, following factors were independently associated with the risk of persistent smoking: female, low income, high-risk alcohol use, high body mass index (> or = 25 kg/m2), presence of household members who smoke, and longer duration of smoking. Alcohol Use Disorders Identification Test showed a positive association with the risk of persistent smoking (P for trend = 0.012). In conclusion, more efforts for smoking cessation should be in place for the cancer survivors with those risk factors associated with the persistent smoking.
