Objectives: Identifying smoking levels is very important for public health assessment along with accurate assessment of smoking rates is important for establishing and evaluating smoking cessation policies. Identifying the validity of the questionnaire is important in determining whether the self-reported questionnaire provides accurate smoking status.
Methods: The Korea National Health and Nutrition Examination Survey were used. To analyze the characteristics of inconsistency by analyzing the correspond of self-reported questionnaire data on smoking status and urine cotinine concentration, multiple logistic regression analysis were conducted.
Results: The results of the self-reported smoking accuracy were 22.0% and urine cotinine smoking rate was 24.1%. Sensitivity and specificity were each 95.4% and 95.9%. Self-reported questionnaires on smoking status and characteristics affecting urine cotinine concentration inconsistency were statistically significant at the present marital status with divorce/bereavement.
Conclusion: The accuracy of the self-reported smoking rate was high and the false response rate was low in the smoking questionnaire, confirming that it is similar to the western population with no gender difference. To improve the cause of inconsistency due to divorce (including bereavement), it is necessary to study the improvement of accuracy of national smoking rate by supplementing questionnaire and monitoring continuously.
