Adolescent and young adult substance use remains one of Europe's most entrenched and costly health problems, despite considerable expenditures on alcohol and drug education and prevention programs. It is the leading cause of adolescent and young adult mortality worldwide. Alcohol and illicit drug use at young ages is associated with various high-risk behaviors such as violence, injuries, suicide, depressive disorders, school dropouts and risky sexual behavior; it is a strong predictor of later adult substance abuse and dependence, and is more prevalent among males in almost all societies.Adolescent substance use in Switzerland is among the highest of the European countries. Few longitudinal studies have addressed the critical phase between late teen years and earlyadulthood, as does the current proposal, and most studies come from North America with a completely different socio-cultural background than Switzerland. Behaviors like substance use result from the interaction and interdependence of behavioral, personal, and environmental factors. Environmental and familial factors motivate and reinforce behaviors while personal factors alter the way individuals perceive and respond to the environment.The present study will analyze protective and detrimental factors of substance use, which will lead to specific design preventive actions adequate in the Swiss context. The study therefore has the following main aims:1. To estimate the prevalence and trend of substance use and related consequences among young adults in Switzerland using a sample (quasi-census) of Swiss francophone 19 year-oldmen and a census of the same age group of Germanophone men from the cantons Basel-Stadt, Basel-Landschaft, Solothurn, Aargau, Luzern, Nidwalden, Obwalden und Uri, St. Gallen, Appenzell A.-Rh., Appenzell I.-Rh., Glarus, Graubünden und Schwyz.In addition, the prevalence among subpopulations (e.g., socioeconomic status or neighborhood characteristics, etc.) will be compared.2. To characterize patterns of substance use and changes over time among young adults. In particular, individual trajectories will be modeled and factors associated with onset,intake and abstinence will be examined.3. To identify risk and protective factors associated with young adult substance use in the multi-level context of individual, family and societal/environmental levels guided by a developmental social context model.4. Interventions such as brief interventions or internet based interventions will be tested. The present cohort study is designed to assess the substance use patterns and related consequences in 19 year-old men following mandatory army recruitment procedures and tofollow them up into middle-age adulthood over a period of possibly at least 20 years. The present application seeks for prolongation of funding for the last two years of the initially planned 5-year study. Baseline data and first follow-up after 18 months has been obtained, the prolongation request includes a 2nd follow-up after 36 months. Cohort participants have been enlisted during the year 2010 in three centers responsible for processing all francophone Swiss men and all germanphone Swiss men in the cantons of Basel-Stadt, Basel-Landschaft, Solothurn, Aargau, Luzern, Nidwalden, Obwalden und Uri, St. Gallen, Appenzell A.-Rh., Appenzell I.-Rh., Glarus, Graubünden und Schwyz.Since recruitment procedures are mandatory, the present study is representative of 19 year-old men in Switzerland.In summary, the main research purpose is to examine the development of substance use and related consequences, from the late teens to young adulthood within a multi-level context of individual-environment interaction.
