Key result
A 6-month mHealth intervention providing personalized feedback via a smart bracelet and smartphone app did not significantly reduce systolic blood pressure or weight compared to routine management in hypertensive patients.
Why the study?
Lifestyle interventions are recognized treatments for noncommunicable diseases, but the efficacy of a bespoke mHealth approach delivering personalized feedback to improve blood pressure and weight in community settings needed evaluation.

BACKGROUND: Lifestyle interventions have been recognized as a line of treatment for noncommunicable diseases. This study aimed to evaluate a bespoke mHealth approach to deliver personalized feedback to improve blood pressure and weight for hypertensive patients in community settings. METHODS: A total of 307 participants, 50 from each community, were expected to be in the intervention or control group. A professional health facilitator was assigned for each of the 6 communities. The primary outcomes of the study are the reduction in blood pressure and weight at baseline and postintervention. RESULTS: Of 307 recruited, 192 participants (62.5%) completed the study (intervention: 104 and control: 88). There was no difference in attrition rates between the 2 groups (33.5% vs 41.9%, P = .291). After 6 month of intensive feedback intervention through the mHealth approach, patients had better blood pressure (133.4 ± 15.3 vs 139.7 ± 16.0) compared with control. CONCLUSIONS: People who were adherent to the intervention demonstrated a clinical benefit in weight and blood pressure.

Zhang et al. (2022) conducted an RCT in Hypertension (n=307). mHealth approach (DASH app and smart bracelet) vs. Routine management was evaluated on Change in systolic blood pressure at 6 months (MD -3.2 mm Hg). A 6-month mHealth intervention providing personalized feedback via a smart bracelet and smartphone app did not significantly reduce systolic blood pressure or weight compared to routine management in hypertensive patients.
