Background: International Tobacco Control project (ITC) was performed in South Korea for evaluation of the effects of smoking control policies in compliance with FCTC. We tested the association between the level of knowledge and heaviness of smoking index (HSI), and intention to quit smoking.
Methods: The study followed the same methodology by ITC policy evaluation project. Trained call center staffs interviewed 2000 current smokers (1800 men and 200 women, aged 19-65) on the phone. Tobacco-related knowledge was evaluated by asking participants the diseases related with smoking such as stroke, impotence, visual loss, peripheral vascular disease, bladder cancer, and breast cancer. Multivariate logistic regression was used for statistical analysis, which was adjusted by age, sex, education level, annual household income, alcohol consumption frequency, and heaviness of smoking index.
Results: High HSI score (3-6) was associated with low knowledge score (Odds ratio (OR) 0.80, 95% confidence interval (CI) 0.65-0.99). Smokers who had intention to quit smoking in any future were also more likely to be in a high knowledge score group (10-14 vs. 0-9 out of 14) (OR 1.50, 95% CI 1.19-1.89).
Conclusion: Smokers who had higher HSI or had no intention to quit tended to have lower level of knowledge regarding health risk of smoking. This implies that education and public awareness on health risk of tobacco could be more effective when targeted to these smokers.
