Intervention: Reduction of tobacco content on social media through federal regulatory strategy
Who it was tested with: 139,624 participants across 24 datasets, with 100,666 adolescents (72%), 20,710 young adults (15%), and 18,248 adults (13%).
Experience from people who deliver programmes: stories, case studies and lessons learned. Valuable for understanding how and why, and for spotting what to test next, but not a measure of effect.
"Studies reporting odds ratios (ORs) for self-reported exposure to, or experimentally manipulated, tobacco content on social media and lifetime tobacco use, past 30-day tobacco, and susceptibility to use tobacco among never users." The meta-analysis synthesized evidence from studies using both observational and experimental designs to estimate associations, with the experimental component strengthening the evidence tier.
Meta-analysis included observational studies which cannot establish causation; high heterogeneity across studies (I² 73-94%) indicates substantial variation; direction of causality cannot be determined from included studies
