Smoking Prevalence and the Association between Smoking and Sociodemographic Factors Using the Korea National Health and Nutrition Examination Survey Data, 2008 to 2010

Abstract

Using data from the Korea National Health and Nutrition Examination Survey collected from 2008 to 2010, smoking prevalence for Korean adults (n = 11,681) by gender and age group and the association between smoking and sociodemographic factors were evaluated. Smoking prevalence was 42.3% for men and 5.6% for women. Young adult (YA) males, ie, 19 to 24 and 25 to 34 years old, were 2.45 (95% CI: 1.60, 3.73) and 5.05 (95% CI: 3.83, 6.66) times more likely to smoke compared to male adults aged 65 and above (31.6%) after controlling for sociodemographic factors. The association between smoking and marital status was different by gender. In South Korea, the high smoking prevalence among young adults is a troubling pattern. The high smoking prevalence among widowed or divorced women is also concern.
