Pooling the evidence, social media–based diabetes education produced a small but real improvement in blood-sugar control, though results varied widely and short programs showed no clear benefit.
More and more diabetes education is delivered through social media, but it has been unclear whether it actually helps people control their blood sugar. Led by Lisa Diaz, this review gathered the existing studies and combined their results to find out. Across 13 studies, social media–based education was linked to a small but statistically significant improvement in HbA1c, a standard measure of blood-sugar control. The effect varied a lot from study to study, and programs lasting three months or less showed no clear benefit.
Following PRISMA 2020 guidelines, the team searched PubMed, CINAHL, Web of Science, and PsycINFO, screening 790 records and including 13 studies, 11 of them randomized controlled trials, in the meta-analysis. Risk of bias was assessed with the Cochrane RoB 2 tool, and a random-effects model pooled the change in HbA1c.
The pooled effect favored the interventions (about a 0.44 percentage-point drop in HbA1c), but with substantial differences between studies (I² = 91%). An exploratory analysis of program length suggested that shorter interventions, three months or less, did not produce a clear effect. The review points to a promising but still-mixed evidence base, and to the need for longer, higher-quality trials.
Pooled across studies, social media–based education modestly improved HbA1c.
Effects differed a lot between studies, so the overall picture is still mixed.
Programs of three months or less showed no clear benefit.
The evidence base calls for longer, higher-quality studies.
