Despite a steady decline in average annual consumption of pure alcohol in France since the early 1960s, certain indicators of alcohol use have risen among young people over the past decade. This article aims to provide an overview of the scientific evidence regarding validated interventions for preventing alcohol consumption among children and adolescents. This review was conducted using a specific method for selecting and analyzing the scientific literature and classifying the interventions identified. Twenty-seven interventions were identified as effective in preventing alcohol consumption among young people: 6 target children under 10 years of age, 9 target 10- to 15-year-olds, and 8 target young people over 16 years of age, while 4 address alcohol availability. More than half (17) are universal interventions. Among those targeting children and adolescents, many involve parental participation. This study highlights the complementary nature of interventions that directly target individuals and those that address alcohol availability. It also highlights potential synergistic effects resulting from interventions that demonstrate an impact not only on young people’s alcohol consumption but also on their use of other psychoactive substances and on their mental health.
