abstract="Although fewer adolescents are consuming alcohol than was the case in previous decades, those who are consuming alcohol are still exposed to alcohol-related harms. While the evidence for the effectiveness of universal, school-based interventions is  limited, a recent cluster randomised controlled trial (The STAMPP Trial) reported a  significant effect at 10 months post-intervention of a combined classroom/parental  intervention on heavy episodic drinking (HED) in the previous 30 days, but no  significant effect on the number of self-reported alcohol-related harms (ARH)  experienced in the previous 6 months. This follow-up study sought to examine  intervention effects 24 months after delivery of the intervention (+ 57 months from  baseline, or + 34 months post-intervention). Participants were 5029 high school  students in STAMPP (38% of 12,738 pupils originally randomised into the trial), from  87 schools (82.3% of schools recruited in the original STAMPP trial). Outcomes were  assessed using two-level random intercepts models (logistic regression for HED and  negative binomial for number of ARH). <br><br>RESULTS of the present study show that the  intervention effect for HED deteriorated over the following 2 years (OR declined  from 0.60 to 0.97), and there was still no difference in ARH. This was due to an  increase in the prevalence of intervention students' HED rather than a reduction in  prevalence in control students. <br><br>RESULTS are discussed in the context of prevention  initiatives.<p /> <p>Language: en</p>",
