Objectives. To assess trends in association between alcohol use and cigarette smoking among Japanese adolescents.

Methods: Nationwide cross-sectional surveys were conducted in 1996, 2000 and 2004. Survey schools were sampled randomly. Enrolled students were asked to fill up a self-reporting anonymous questionnaire on smoking behavior. Questionnaires were collected from 115,814 students in 1996, 106,297 in 2000, and 102,451 in 2004 through sampled junior and senior high schools throughout Japan. Current user was defined as those who had used at least once during the previous 30 days.

Results: Prevalence of alcohol use and cigarette smoking prevalence (lifetime, current, and daily) in 2004 was decreased in both sexes and in all school grades. Proportions of user of both, cigarette only, alcohol only, and abstinence were 12.7%, 4.5%, 25.5%, 57.3% in 1996, and 11.2%, 4.1%, 25.9%, 58.8% in 2000, and 7.0%, 2.4%, 22.5%, 68.1% in 2004. Prevalence of alcohol use among smoker has decreased survey by survey, whereas that among non smoker has not changed. When co-occurrence risk of smoking and alcohol use was analyzed using multiple logistic regression adjusted by gender and age, the odds ratio was 5.5 (95%CI, 5.3-5.7) in 1996, 5.4 (95%CI, 5.2-5.6) in 2000, and 7.8 (95%CI, 7.4-8.2) in 2004.

Conclusions: We observed that co-occurrence of smoking and drinking among Japanese adolescents. Although prevalence of smoking and drinking decreased in recent years, health-compromising behaviors have accumulated to selected adolescents.

Learning Objectives:
1. Recognize mothdology of descriptive epidemiology. 2. Evaluate association among some health-compromising behaviors among adolescents. 3. Analyze health related factors among adolescents, and develop measures for smoking and drinking control among adolescents.
