1510-P: Systematic Literature Review and Meta-Analysis: Social Media Use for Self-Management Education and Support for Type 2 Diabetes Mellitus

Introduction and Objective: Social media interventions are being used for diabetes self-management education and support (DSMES), but evidence of their effectiveness is limited. This review and meta-analysis explored the impact of social media-based DSMES on glycemic control in adults with type 2 diabetes (T2DM) and the effect of intervention duration on outcomes. Methods: A PRISMA 2020-compliant systematic review was conducted using PubMed, CINAHL, Web of Science, and PsycINFO, with 789 records screened in Covidence by two reviewers. Eligible studies, published in English within the last 10 years, involved adults with T2DM, reported HgbA1c outcomes, and utilized social media for DSMES interventions. Risk of bias was assessed using the Cochrane Risk of Bias 2 (RoB 2) tool for randomized controlled trials. A random-effects meta-analysis estimated pooled standardized mean differences, with subgroup analyses based on intervention duration; heterogeneity was assessed using the I² statistic. Results: Twelve studies showed a significant decrease in HbA1c levels from baseline (M = 8.48, SD = 0.96) to post-intervention (M = 7.37, SD = 0.85); t(11) = 3.93, p = .002, d = 1.13. Overall, the included studies were judged to have low to some concerns of risk of bias based on RoB 2 assessment. The meta-analysis included 10 randomized controlled trials, most of which involved middle-aged adults from Asia and the Middle East, with only two from North America. Social media interventions improved glycemic control significantly (effect size −0.62; p = .045), with moderate heterogeneity. Subgroup analysis indicated no significant effect for shorter interventions (≤3 months; effect size −0.04; p = .83), while longer interventions (>3 months) resulted in greater HbA1c reductions (effect size −1.48; p = .004). Conclusion: Social media-based DSMES enhances glycemic outcomes in adults with T2DM, particularly with interventions over three months, suggesting a need for further exploration of these strategies.
