Correlates and Risk Factors of Probable Alcohol Dependence Group among Korean Adult Drinkers: Nationwide Probability Sample Survey / 신경정신의학

ABSTRACT

OBJECTIVES: The aims of this study were 1) to estimate prevalence rates of drinkers, two subtypes of drinkers-drinkers without dependence and drinkers with probable alcohol dependence(AD) using CAGE, and 2) to find out the correlates of sociodemographic variables and drinking patterns of the drinkers with probable AD by comparing those of the drinkers without dependence, 3) to analyse risk factors for the drinkers with probable AD. METHODS: Using data from face-to-face interviews conducted during 1995, we investigated the prevalence and characteristics of two subtypes of drinkers in a national probability sample of 1,695 drinkers 20 years of age and older. We defined drinkers with CAGE scores 2 and over as drinkers with probable AD, and scores less than 1 as drinkers without dependence. The comparisons of sociodemographic characteristics and drinking patterns between two subtypes of drinkers were examined through chi-square test using weighted data. Statistical analysis including multiple logistic regression analysis were done for each sex, respectively. Because of the large number of coefficients estimated, Bonferroni's method was used to compute p values. RESULTS: The results were as follows 1) Prevalence of the drinkers was 33.7% in the total sample. Prevalence rate of male and female drinker were 26.3% and 7.40%, respectively. Prevalence of the drinkers with probable AD was 10.9%. For males the prevalence of the drinkers with probable AD was 9.99% and for females 0.94%. 2) According to sociodemographic variables between drinkers without dependence and drinkers with probable AD, males drinkers with probable AD were older, less educated, more depressive, married marital status and were more likely to have occupations of service section than male drinkers without dependence. Female drinkers with probable AD were less educated, more depressive and had less monthly income than drinkers without dependence. 3) As for the drinking patterns, male drinkers with probable AD drank more frequently, had more drinks, had more trying to quit drinking and preferred Soju. Female drinkers with probable AD drank more frequently, had more drinks, were more trying to quit drinking, too. 4) Multiple logistic regression analysis showed that the risk factors for male drinkers with probable AD were lower education(< or =6 years) and depressive symptoms. For females, depressive symptoms and lower education(< or =6 years) were strongly indicative of risk factors though not reaching the statistical significance. CONCLUSIONS: Prevalence of the drinkers with probable AD was 10.9%, and male to female ratio was 10.61, which was lower than previous results. Depressive symptoms and lower education proved to be strong predictors for alcohol dependence. This suggest that early detection and treatment of depression and public education for the lower education group should be important.
