This webinar will provide an overview of the effectiveness of peer-led interventions among young people aged 11-21 years.
Dr. Georgie MacArthur from the University of Bristol will be leading the session and presenting findings from her systematic review. Tobacco, alcohol, cannabis and other illicit drug use can have negative consequences on the health of young people. This review and meta-analysis assessed and quantified the effectiveness of peer-led interventions on tobacco, alcohol and illicit drug use among young people. Seventeen randomized control trials were included and 10 studies were pooled for meta-analysis. Peer-led interventions reduced odds of smoking (OR=0.78, 95% CI 0.62 – 0.99, p=0.040) and alcohol use (OR=0.80, 95% CI 0.65 – 0.99, p=0.034) among young people, compared to controls.
