Abstract

Distance education or reminder by texting short message may improve HbA1c level and medication adherence to type-2 diabetes. Electronic databases (PubMed, EBSCO, Elsevier, Springer, Wiley, and Cochrane) were searched systematically for published studies up to Mar 2019. SMD and 95% confidence interval (CI) were used to evaluate the intervention effect on HbA1c level and medication adherence. The heterogeneity of the study was estimated with the I2 statistic. The publication bias was described by Beggs' test, Egger's test and plot. Ten studies with 380 interventions and 275 controls were included in this meta-analysis. The Hba1c overall SMD was -0.49%, 95% CI -0.75 to 0.22%, and the overall SMD was 0.96%, 95% CI 0.45-1.47 for medication adherence. The I<sup>2</sup> and P were 64.90%, 0.002 and 56.40%, 0.10 respectively for Hba1c level and medication adherence. SMS intervention was effective for HbA1c level and medication adherence according to this study for T2DM over first 6 months.
