Targeted school-level interventions to prevent multiple risk behaviours relating to alcohol, tobacco and drug use
Summary of the evidence
A systematic review with meta-analysis (Tinner et al., 2022, 66 studies) assessed the effects of individual-, family- and school-based interventions to prevent multiple risk behaviours relating to alcohol, tobacco and drug use in young people aged 8-25 years. Results found that:
- for targeted school-level interventions, there was low quality evidence of no or a small short-term benefit: alcohol use (OR 0.90, 95% CI: 0.74-1.09), tobacco use (OR 0.86, 95% CI: 0.66, 1.11), cannabis use (OR 0.84, 95% CI: 0.66-1.07) and other illicit drug use (OR 0.79, 95% CI 0.62-1.02).
