Summary

This pilot study tested three simple ways to encourage blood sugar screening in 102 overweight or obese adults without known diabetes: a text message, a patient portal message, or a mailed letter. The goal was to see which method was most acceptable and effective at getting people to complete a hemoglobin A1c test. Results will help design a larger trial to improve early detection of prediabetes and type 2 diabetes.
