HealthDay News — For low-income Hispanic patients with poorly controlled type 2 diabetes, a text messaging intervention can improve glycemic control, according to a study published online in Diabetes Care.

Addie L. Fortmann, PhD, from the Scripps Whittier Diabetes Institute in San Diego, and colleagues conducted a randomized trial involving 126 low-income Hispanic participants with poorly controlled type 2 diabetes. Participants were randomized to receive either the Dulce Digital intervention, which included receipt of up to 3 motivational, education, and/or call-to-action text messages per day over 6 months, or usual care.

The researchers found that, compared with usual care, there was a significantly greater reduction in HbA1c over time in the Dulce Digital group (P =.03). There were no statistically significant effects for secondary clinical indicators. The number of blood glucose values that participants texted in was a significant predictor of HbA1c at month 6 (P <.05). High satisfaction and acceptability ratings were seen for the Dulce Digital intervention.

“Use of a simple, low-cost text-messaging program was found to be highly acceptable in this sample of high-risk, Hispanic individuals with type 2 diabetes and resulted in greater improvement in glycemic control compared with usual care,” the authors write.

The Investigator-Initiated Study Program of LifeScan provided glucose testing meters and strips for all participants.
