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 early adulthood, 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 study analyses protective and detrimental factors of substance use, which will lead to design specific 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 6000 Swiss 19 year-old men at baseline. In addition, the prevalence among subpopulations (e.g., socioeconomic status or neighborhood characteristics, etc.) are compared. 2. To characterize patterns of substance use and changes over time among young adults. In particular, individual trajectories are modeled and factors associated with onset,intake and abstinence are 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. 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 (around 98% of the male population of this age) and to follow them up into emerging adulthood over a period of possibly at least 10 years. Cohort participants have been enlisted during the year 2010 and 2011 in three centers responsible for processing all francophone Swiss men and all germanphone Swiss men in the cantons of Bern, Basel-Stadt, Basel-Landschaft, Solothurn, Aargau, Luzern, Nidwalden, Obwalden, Uri, St. Gallen, Appenzell A.-Rh., Appenzell I.-Rh., Glarus, Graubünden und Schwyz (representing 21 of 26 cantons in total).Since recruitment procedures are mandatory, the present study is representative of 19 year-old men in Switzerland.The present application seeks for maintenance of the cohort and the preparation of the 2nd follow-up over the following two years (April 2014 - March 2016). Baseline data and first follow-up (90% completion) after 15 months have been collected. The application then seeks for funding of a second follow-up at the age of 25-26 (April 2016-March 2018). In the long-term a third follow-up around the age of 30 years is forseen. 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-family-environment interaction.
