Diabet. Med. 28, 455–463 (2011) Abstract Aims To assess the effect of mobile phone intervention on glycaemic control in diabetes self‐management. Methods We searched three electronic databases (PubMed, EMBASE and Cochrane Library) using the following terms: diabetes or diabetes mellitus and mobile phone or cellular phone, or text message. We also manually searched reference lists of relevant papers to identify additional studies. Clinical studies that used mobile phone intervention and reported changes in glycosylated haemoglobin (HbA 1c ) values in patients with diabetes were reviewed. The study design, intervention methods, sample size and clinical outcomes were extracted from each trial. The results of the HbA 1c change in the trials were pooled using meta‐analysis methods. Results A total of 22 trials were selected for the review. Meta‐analysis among 1657 participants showed that mobile phone interventions for diabetes self‐management reduced HbA 1c values by a mean of 0.5% [6 mmol/mol; 95% confidence interval, 0.3–0.7% (4–8 mmol/mol)] over a median of 6 months follow‐up duration. In subgroup analysis, 11 studies among Type 2 diabetes patients reported significantly greater reduction in HbA 1c than studies among Type 1 diabetes patients [0.8 (9 mmol/mol) vs. 0.3% (3 mmol/mol); P = 0.02]. The effect of mobile phone intervention did not significantly differ by other participant characteristics or intervention strategies. Conclusions Results pooled from the included trials provided strong evidence that mobile phone intervention led to statistically significant improvement in glycaemic control and self‐management in diabetes care, especially for Type 2 diabetes patients.
