Prevalence and intervention strategies of health misinformation among older adults: A meta-analysis

Abstract

The rapid expansion of the Internet and social media has intensified the spread of health misinformation, posing significant risks, especially for older adults. This meta-analysis synthesizes evidence on the prevalence and interventions of health misinformation among older adults. Our findings reveal a high prevalence rate of 47% (95% CI [33%, 60%]), surpassing recent estimates. Offline research settings have a higher prevalence of health misinformation. Despite methodological variances, the prevalence remains consistent across different measures and development levels. Interventions show significant effectiveness (Hedges’ g = 0.76, 95% CI [0.25, 1.26]), with graphic-based approaches outperforming video-based ones. These results underscore the urgent need for tailored, large-scale interventions to mitigate the adverse impacts of health misinformation on older adults. Further research should focus on refining intervention strategies and extending studies to underrepresented regions and populations.
