Differences between the factors affecting high-risk drinking and those affecting smoking in Korea

This study examines the factors influencing high-risk drinking and cigarette smoking and assesses the differences in those factors between 2 risky behaviors in Korea. A national, cross-sectional health behavior survey was performed on 12,303 households in 2006 and a data set of 2925 adult males was analyzed using bivariate probit estimation model. The likelihood of high-risk drinking rose with an increase in the level of income, whereas that of smoking was lowest in a medium income. White-collar workers were more at risk of high-risk drinking than blue-collar workers. Conversely, blue-collar workers tended to smoke more frequently than white-collar workers. Body mass index showed a positive association with high-risk drinking, but it had no significant relationship with smoking. Significant differences may exist in associations between factors influencing high-risk drinking and those influencing smoking. The comprehensive understanding of these differences would allow for the development of appropriate public health programs.ope
