Effectiveness evaluation of the school-based drug prevention program #Tamojunto in Brazil: 21-month follow-up of a randomized controlled trial.

Introduction: A school-based randomized controlled trial was conducted in 2014/2015 with students in 7 and 8 grades in 72 public schools in 6 Brazilian cities. A total of 5028 students were linked (75, 7%) in at least one of the two waves of follow-up (9 months and 21 months later). The principal research question was whether this 12-lesson program delays the initiation of alcohol, tobacco, inhalants and binge drinking among early adolescents when compared to usual care, that is, no prevention program in Brazilian schools, after 21 months of follow up.

The #Tamojunto Drug Prevention Program in Brazilian Schools: a Randomized Controlled Trial.

A randomized controlled trial was conducted in 2014 with 7th and 8th grade students from 72 public schools in 6 Brazilian cities. This trial aimed to evaluate the effects of an adapted European school-based drug prevention program Unplugged, called #Tamojunto in Brazil, which was implemented by the Ministry of Health as part of public policy. The experimental group (n = 3340) attended 12 classes in the #Tamojunto program, and the control group (n = 3318) did not receive a school prevention program.

Efficacy evaluation of the school program Unplugged for drug use prevention among Brazilian adolescents.

Background: Most Brazilian schools do not have a continuous program for drug use prevention and do not conduct culturally adapted activities for that purpose. This study evaluated the impact of the Unplugged program on drug use prevention among children and adolescents in public middle schools of Brazil.

Methods: A non-randomized controlled trial was conducted in 2013 with 2185 students in 16 public schools from 3 Brazilian cities.

Childhood alcohol use may predict adolescent binge drinking: a multivariate analysis among adolescents in Brazil.

Objectives: To test the hypothesis that first alcohol use during childhood is associated with heavy drinking patterns during adolescence and with parental drinking patterns and parental rules about alcohol consumption.

Study Design: A national cross-sectional survey of 17,371 high-school students. Students were drawn from 789 public and private schools in all the Brazilian state capitals using a multistage probabilistic sampling method and a self-report questionnaire.
