Diabetes and hypertension frequently coexist, with approximately 50 percent of individuals diagnosed with diabetes having a dual diagnosis. These dual comorbidities are associated with a fourfold increased risk of stroke and myocardial infarction compared with individuals without the disease. The prevalence of these diseases is much higher in low-income and racial/ethnic minority patients. The ubiquity of smartphones in many lower-income communities may make mHealth approaches particularly useful as a patient self-management tool. The purpose of this project is to form a community collaborative to bring together patients, community leaders, and healthcare professionals to identify approaches and priorities for research on leveraging mHealth technologies for patient management of diabetes and hypertension.
