BACKGROUND: Alcohol has much effect on our lives as a taste food that people in almost all of the world generally have had. The effects of alcohol cause social problems as well as physical and psychological problems. Recently, interest about drinkirg increasingly rises as the rate of drinking accident increases in Korea. For this, our study examined the amount of alcohol consumption and early at-risk alcohol intake. METHODS: The prepared questionnaire was presented to subjects who were employees in Inchon . The anonymous, self-administered questionnaire was composed of questionnaire concerning alcohol consumption, early at-risk alcohol intake and doctor's role in drinking behaviour. RESULTS: Among 305 subjects, there were 189 (62%) men, 116 (38%) women whose mean age was 37. 9years. 87(28.5%)subjects were classified as high alcohol group and 218(71.5%) low alcohol group. High alcohol group was defined as early at-risk alcohol intake for men who were consuming 135g of alcohol per day, 630 per week and for women 90g per day, 270g per week. Low alcohol group was defined as early at-risk alcohol intake for men whose consumption was 90g per day, 450 per week and for women 45g per day, 270g per week . Mean alcohol consumption of drinker was 158.9g per week. 3 days per week people should not drink in order to avoid risk Although 54% of respondents thought doctors should ask about their drinkirg habits, only 16.4% of respondents reported ever being asked about alcohol intake on the subject. CONCLUSION: Early at-risk drinking subject in the study was much more than those suggested by NIH(National Institutes of Health). We conclude that primary care physicians should take more interest in screening, treating and preventing alcohol related problems and advise and educate patients to cut down or quit drinking.
