Veränderungen im Tabak-, Alkohol- und Cannabiskonsum von Jugendlichen im Zeitraum von 2002 bis 2010 in Deutschland

Background: So far, little is known about long-term trends in the use of psychoactive substances by adolescents in Germany. However, these results are urgently required for a target-orientated prevention. The aim of the present study is to analyse age- and gender-specific prevalences and trends in tobacco, alcohol und cannabis use among young people in Germany from 2002 to 2010. Methods: Data were obtained from the German part of the WHO collaborative study "Health Behaviour in School-aged Children (HBSC)o" conducted in 2002, 2006, and 2010. The analysis is based on 11 917 students aged 13 and 15 years. Age- and gender-specific trend analyses were done using log binomial regression models. Results: The prevalences of regular tobacco and alcohol use among 13- and 15-year-olds decreased from 2002 to 2010, independent of gender. A similar effect was found for repeated drunkenness and for the 12-month prevalence of cannabis use. In 2010 about 15% of the 15-year-olds consumed tobacco and alcohol at least once a week, 30% reported 2 or more episodes of drunkenness and 11% used cannabis in the last 12 months. The corresponding values for 13-year-olds with a prevalence of 3-5% on average are considerably lower. Discussion: Following an increase over the 1990s the HBSC data shows a strong decrease in the use of psychoactive substances over the last 8 years which can be interpreted as a success of recent preventive efforts. However, noticeable is a clear flattening of the decrease from 2006 to 2010. This underlines that preventive actions must continue play a central role in health policy and practice.
