[Pathological gambling in adolescence].

Today's juveniles are the first generation to be raised in an environment where gambling is very accessible and socially acceptable. The recent legalization of Internet gambling has increased this accessibility. With 28,8 millions of gamblers in France in 2010, many believe that gambling is an innocent leisure activity. The first results of the national survey on the prevalence of gambling practices conducted in France show that in 2010, 1.3% of the population had a gambling problem. Also, despite the prohibition of gambling to minors, the mean age of onset of gambling behavior in the world is 11.5 years. Gambling (even non-problematic) in adolescence is associated with poor school performance, criminal behavior and family conflict. Recreational gambling shares with pathological gambling high rates of psychiatric comorbidities in adults, and risk behaviors among adolescents. Similarly, international studies show prevalence of problem gambling 2 to 4 times higher among adolescents than among adult, 3.5% to 8% of adolescents between 12 and 17 are pathological gamblers. The validity of the screening instruments and the frequency of spontaneous recovery in adulthood are discussed to explain the high prevalence in adolescence. This article proposes a focus on the practice of gambling in adolescence and its characteristics when the practice becomes pathological. We discuss the epidemiological, diagnostic, etiologic and therapeutic aspects of this problem. Three major types of risk factors implicated in gambling problems are identified: some of them are related to the subject (individual factors), others are related to the object of the addiction, here the gambling activity by itself (structural factors) like Internet with the recent legalization of gambling online, and the last are related to environment (contextual or situational factors). Thus, the development and maintenance of pathological gambling in youth seems to be conditioned by the interaction of a person and a gambling activity, in a particular context. This conceptual model is based on the well-known theory of Olivenstein on toxicomania, which was proposed in the seventies. In France, very few is known about problem gambling in this age and its implications in terms of treatment, prevention and research. There is little in the way of specific treatments for adolescent pathological gamblers so we briefly reviewed possibilities and limits. We discuss the importance to develop prevention, in particular to delay the initiation, and the necessity of research to develop screening instruments and news studies to have a better knowledge of this population.
