PREVALENCEAND PREDICTORS OF SUSTAINED SMOKINGAFTER CANCER DIAGNOSIS
IN KOREAN MEN

Background: Recent studies have suggested that smokers with new cancer diagnosis are more likely to quit smoking compared
with those without cancer. However, up to 70% of cancer survivors continue to smoke. Smoking has a significant impact on
mortality and morbidity of cancer patients.
Aim: This study aimed to describe prevalence and predictors of sustained smoking after cancer diagnosis among smokers.
Patients & Methods: 15,201 men who were first diagnosed with cancer between January 1, 2004 and December 31, 2011 were
included in the study. Data were obtained from The Korean National Health Insurance database. Changes in smoking status
after diagnosis were investigated for patients with smoking related cancers and those with non-smoking related cancers. The
association between sustained smoking and demographic, socioeconomic, and clinical variables were examined.
Results: Of the 4,680 smokers newly diagnosed with cancer, 2,265 (48%) quitted smoking and 279 (6%) reduced the amount of
smoking. Sustained smoking rate was higher among patients with non-smoking related cancer (54%) than among patients with
smoking related cancer (41%). In univariate analyses, age at cancer diagnosis, pre-diagnosis smoking amount, socioeconomic
status, cancer type, and fasting serum glucose level were associated with sustained smoking (all p-values<0.05). Multivariate
logistic regression analysis showed that patients who were younger (OR =1.36, 95% CI: 1.20-1.54, p <0.001); smoking >20
cigarettes per day (OR =1.23, 95%CI: 1.08-1.40, p=0.001); in low socioeconomic status (OR =1.29, 95%CI: 1.14-1.45, p<0.001);
diagnosed with non-smoking related cancer (OR =1.67, 95% CI: 1.42-1.95, p<0.001); and had high blood glucose level (OR
=1.25, 95% CI: 1.05-1.48, p=0.012) were more likely to continue smoking after cancer diagnosis.
Conclusion: Almost half of male smokers continue to smoke after diagnosis of cancer. Patient age, amount of smoking,
socioeconomic status, and type of cancer might need to be considered when implementing the intervention for smoking
cessation.
