 This systematic review and meta-analysis evaluates the effectiveness of social media and mobile health interventions for cancer screening, finding that they have a promising role in promoting cancer screening participation. The study identifies 39 studies, 35 mHealth and for social media, and finds an overall pooled odds ratio of 1.49, 95% CI 1.31 to 1.70, with similar effect sizes across cancer types. However, the limited number of studies identified highlights the need for further research on social media interventions.
