[Drinking behaviors of Japanese adolescents' problem drinker--report of 1996 national survey].

The first national survey of Japanese adolescent drinking behaviors was conducted in 1996. Based on the survey results, this study focused on high risk drinking behaviors of Japanese adolescent problem drinkers. The subjects were 42,183 junior high school students and 72,396 senior high school students who responded to questions on drinking frequency and drinking quantity among the national survey subjects. The subject students were divided into three groups: normal adolescents, drinkers and problem drinkers by the QF scale. The problem drinkers according to the QF scale accounted for 3% of the junior high school students and 14% of senior high school students. Problem drinkers among both junior and senior high school students had characteristic drinking behaviors such as various drinking occasions, obtaining alcoholic drinks by various methods, drinking hard liquor, and many instances of vomiting or blackouts due to drinking. Many problem drinkers considered that the national law prohibiting minors from drinking was unnecessary because they have the right to decide whether to drink. Both junior and senior high school problem drinkers showed high risk drinking behaviors.
