The study, published in the journal Health Education and Behavior, compared sixth-graders who had used alcohol in the past year to those who had not, in a multi-ethnic, urban sample of more than 4,000 students in 61 Chicago schools. Among this sample, 17 percent had used alcohol within the past year.
The study found that sixth-grade users of alcohol were significantly different from the non-users on almost all risk factors examined. For example, users were more likely to be male, engage in violent or delinquent behavior, and have friends who used alcohol.
Researchers suggest a prevention program prior to sixth grade in which parent involvement is central. Students should receive developmentally-appropriate messages that correct inaccurate perceptions that 'drinking is normal' and that provide tweens with the skills to refuse alcohol. In addition, interventions should include parental involvement in order to help create opportunities for increased parent-child communication and provide parents with the skills to increase monitoring.
Forskarna verkar alltså anse att alkohol gör 12-åringar till pojkar som bråkar. Jag törs anta att det finns möjlighet till andra tolkningar.
