Psychiatric epidemiology in Korea. Part II: Urban and rural differences.

This paper compares the findings in rural Korea and in the urban capital city of Seoul, Korea. In rural Korea 1966 subjects and in Seoul 3134 subjects were interviewed with the National Institute of Mental Health Diagnostic Interview Schedule. We found that the prevalence of psychiatric disorders, including alcohol dependence, was higher in rural Korea than in the urban setting. Comparing men and women, the prevalence of psychiatric disorders was higher in women. The exception was alcohol abuse/dependence, which was much higher among men, as was antisocial personality disorder. Comparison of prevalence by age groups showed that, in contrast to American studies, there was a tendency for prevalence to increase with increasing age. Alcohol abuse/dependence was much higher in rural Korea compared with St. Louis. Drug abuse/dependence was much higher in St. Louis. Other interesting similarities and differences are discussed.
