Background: Self-reporting of smoking status is thought to be unreliable. In its place, urinary cotinine level is a useful marker of current smoking status. This study was conducted to evaluate the agreement between self-reported smoking status and a urinary cotinine test in high school students.
Methods: The study subjects were 227 high school students in Daegu city. Questionnaires were used to collect socioeconomic data and information about cigarette use, and a urinary cotinine test was performed on all subjects during the initial evaluation. A chi-square test was used to evaluate differences between participants whose self-reported results and urinary cotinine test were consistent and those whose self-reported results and test were inconsistent.
Results: The overall prevalence of smoking was 6.6% by self-report and 22.9% by urinary cotinine testing. In a comparison of socioeconomic variables between participants whose results were consistent vs. inconsistent, school year and grades were statistically significant, P<0.001 and P=0.024, respectively.
Conclusion: The agreement between self-reported and urinary cotinine test results in evaluating the prevalence of smoking among high school students was low, and self-reporting was thought to be unreliable in determining smoking status in adolescents. Therefore, the use of objective methods such as urinary cotinine testing should be considered in the evaluation of smoking prevalence.
