Brief Summary

Impact of marketing of alcohol products on young people

Detailed Description

Responsible for 3.3 million deaths worldwide, alcohol consumption causes diseases (liver cirrhosis, cancers, etc.) and social problems (injuries, road accidents, alcohol dependence, etc.). With one of the highest consumption rate in Europe, alcohol is the second cause of avoidable mortality in France after tobacco (49.000 alcohol attributable deaths in 2009) and its social cost is estimated to 120 billion euros. French teenage population is particularly associated with heavy drinking patterns: in 2014, 49% of 17-year olds declared heavy episodic drinking.

In that regard, several measures are recommended by health actors to combat this issue: minimum unit pricing, sales ban to minor, low blood alcohol concentration for drivers, etc. A specific measure concerns alcohol advertising restrictions. Some countries implemented alcohol advertising regulation laws (Poland, Sweden, Finland, Estonia, etc.), including France with the Evin law passed in 1991. This French law mandates advertising (and packaging) content to strictly convey factual information and objective qualities of alcohol products and thus bans attractive ads based on image and lifestyle evocations (seduction, power, etc.).

The objective of this research is to investigate whether statutory framework for alcohol advertising (e.g., Evin law) can effectively protect people against misleading, suggestive, and appealing content. Little research has been conducted on this topic in spite of WHO's recommendations (most research has explored the influence of exposure to ads but not the impact of content).

Group	Intervention	Description
Experimental arm	MRI	Patients (60) will be selected from the Alcohol Use Disorders Identification Test (AUDIT-C) : * "light drinkers" (score between 1 to 3) * "heavy drinkers" (score between 4 to 7) Two clinical visits will be realized in less than 4 weeks
Experimental arm	Alcohol Use Disorders Identification Test	Patients (60) will be selected from the Alcohol Use Disorders Identification Test (AUDIT-C) : * "light drinkers" (score between 1 to 3) * "heavy drinkers" (score between 4 to 7) Two clinical visits will be realized in less than 4 weeks

Primary Outcome Measures

Name	Time	Method
Changes in brain activation in areas involved in the control of reward and motivation when looking at neutral versus contextual ads	Month 1	Significant change in cerebral activity (expressed as a significant variation in hemodynamic response BOLD) in the condition of alcohol ads with versus without context (party, sport, people) in areas involved in the control of reward and motivation (striatum dorsal, insula)
