Prevalence and demographic correlates of alcohol-related problems in Japanese employees.

To examine the relationship of basic sociodemographic characteristics to alcohol-related problem in Japanese employees, a questionnaire survey was conducted of a total of 2,581 employees of a computer factory in a suburb of Tokyo. The questionnaires included items on gender, age, marital status, social class (i.e., education, family income and occupation), alcohol consumption, and the Kurihama Alcoholism Screening Test (KAST). Data from 1098 male and 265 female current drinkers aged 20 years or older were analyzed; 15% and 6% of the male and female subjects, respectively, were classified as having alcohol-related problems on the basis of the KAST score (13% and 4% of the entire study population, respectively). Multiple logistic regression analysis indicated that alcohol-related problems were more prevalent in the less educated, managers and those who had a high alcohol consumption. The results suggested that education and occupation are important factors related to alcohol-related problems in Japanese employees.
