Feedback based on health advice via tracing bracelet and smartphone in the management of blood pressure among hypertensive patients: A community-based RCT trial in Chongqing, China
Abstrakt
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.
