Modest Gains for Text Message Intervention in Type 2 Diabetes

Cardiovascular complications are a major cause of morbidity and mortality in type 2 diabetes (T2D).Effective management depends on controlling modifiable risk factors, such as hyperglycemia, hypertension, and dyslipidemia, yet adherence to lifestyle changes and medication regimens remains a persistent challenge. 1Grounded in behavioral science, text message-based interventions have emerged as a potential strategy to reinforce healthy behaviors and support long-term self-management. 2 this issue of JAMA Network Open, Zhang et al 3 present results from a multicenter randomized clinical trial evaluating a mobile text messaging intervention for adults with poorly controlled T2D and elevated cardiovascular risk.The study was conducted across 5 clinical sites in China, enrolling 819 participants with high retention rates over 12 months.Participants in the intervention group received 6 text messages per week related to general information about cardiovascular disease and T2D, healthy diet, medication adherence, glucose monitoring, physical activity, blood pressure control, and smoking cessation, while the control group received usual care.
