Considering broad categories, the 12-month prevalences of any AUD, ND, any mood disorder and any anxiety disorder were 9.7%, 14.4%, 9.5% and 11.8%, respectively, among Americans (Table 2). The corresponding rates (7.1%, 6.6%, 2.0% and 5.2%) among Koreans were significantly lower (p<0.05). After taking into consideration the differences in sociodemographic characteristics, the excess rates among Americans remained statistically significant except for AUD. Of note, however, even though Americans exhibited greater prevalences of most of the disorders considered in this study, the adjusted odds of alcohol dependence (AD) was significantly lower in U.S. than Korea (adjusted OR=0.69). Both in the U.S. and Korea, MDD was the most prevalent mood disorder and specific phobia was the most prevalent anxiety disorder.
