Even though significantly greater prevalence of AD was noted in Korea (5.1%) than in the United States (4.4%), alcohol-dependent Americans were 4 times (OR=3.93) more likely to seek treatment compared to their Korean counterparts. One plausible explanation of the low rate of treatment utilization among Koreans might reflect perceived social stigma among those with SUD or mental health problems, despite the fact that the Korean government offers national health insurance. One may also argue that the Korean culture typically define AD in terms of physiological consequences of drinking, ignoring any alcohol-related social and behavioral problems. Thus, those whose AD symptoms were primarily social, behavioral or interpersonal nature might not perceive the need for treatment.
