While the consumption of alcoholic beverages is deeply rooted in French culinary and festive culture, it also poses a major public health challenge. As such, it is addressed in public health policies and is regularly the focus of prevention campaigns. The 2008–2011 Government Plan to Combat Drugs and Substance Abuse is one example: it addresses alcohol alongside other psychoactive substances and includes various measures aimed at “preventing binge drinking among young people and changing perceptions regarding alcohol.” In the same vein, lawmakers recently voted, as part of the prevention and public health section of the Hospitals, Patients, Health, and Territories Act, to ban the sale of alcohol to those under 18, thereby simplifying a provision that previously distinguished between two age limits (16 and 18) depending on the type of beverage and the point of sale in question. They also voted to ban the sale of alcohol on a flat-rate basis or the free offering of unlimited alcohol, i.e., “open bar” promotions. Monitoring changes in the population’s drinking habits is therefore highly anticipated, particularly regarding adolescents and young adults. While sales data have shown a very clear decline in alcohol consumption in France over the past forty years, repeated cross-sectional self-report surveys of the general population provide a more nuanced measure of how this behavior has evolved. Due to the nature of the data it collects, the Health and Nutrition Barometer allows alcohol consumption to be placed within the precise timeline of the day preceding the survey, offering a detailed description that is highly complementary to that provided by more general surveys such as the INPES Health Barometer, the INSEE Decennial Health Survey, or the Health and Social Protection Survey (ESPS) by the Institute for Research and Documentation in Health Economics (IRDES). These surveys provide a more quantitative and comprehensive description of drinking behaviors: frequency of consumption, episodes of risky drinking, and amount consumed (on an average day, the day before the survey, or on the last day of consumption).[chapter introduction]
