Purpose of Review The objective of this review was to summarize the current scientific evidence of mobile health technology in the primary prevention of type 2 diabetes in patients with prediabetes derived from randomized clinical trials. Recent Findings Few randomized clinical trials are available using mobile health technologies in the prevention of type 2 diabetes. There is heterogeneity in regard to the main study outcomes, duration of interventions, and study findings. Summary Inconsistent findings have been reported whether mobile health technologies are effective in reducing HbA1C levels or the incidence of type 2 diabetes in patients with prediabetes. However, results are promising that mobile health interventions may decrease body weight. Future study may consistently measure changes in glycemic indicators as well as develop elements that better address behavior changes.
