Study focus
This study evaluated a tailored mobile health intervention aimed at improving medication adherence in Black patients with uncontrolled hypertension and type 2 diabetes. Both intervention and control groups showed significant improvements in medication adherence and systolic blood pressure.
Improving medication adherence is crucial for managing chronic conditions like hypertension and diabetes, especially in populations that face health disparities. This study's findings suggest that tailored mobile health interventions can be effective tools for enhancing adherence, potentially leading to better health outcomes in vulnerable populations.
The study was a pilot trial with a small sample size. Results may not be generalizable to all populations with hypertension and diabetes. The attention control group may not fully account for all behavioral influences.

Medication adherence improved significantly in both groups (mean increase of 1.35, P <.001).
Systolic blood pressure decreased significantly (−4.76 mm Hg, P =.04) in both groups.
Diastolic blood pressure showed no significant change (−1.97 mm Hg, P =.20).
Hemoglobin A1c levels did not significantly change (−0.2%, P =.45).
