Points
- A study assessed the effectiveness of a fully digital, autonomous, and AI-based lifestyle coaching program in achieving blood pressure (BP) control among adults with hypertension.
- Participants received a BP monitor and wearable activity tracker, with data collected from these devices and a questionnaire mobile app to train personalized machine learning models for precision lifestyle coaching.
- Significant reductions in systolic and diastolic BP were observed at 12 and 24 weeks, particularly for participants starting with stage-2 hypertension.
- Over the 24 weeks, the percentage of participants with controlled BP increased, while the percentage of participants with stage-2 hypertension decreased.
- The study demonstrated high participant engagement, with an average weekly engagement rate of 92% and minimal manual clinician outreaches. This indicates the potential of digital, autonomous, and AI-based lifestyle coaching to achieve meaningful BP improvements while reducing clinician workloads.
Summary
In a single-arm nonrandomized trial, the effectiveness of a fully digital, autonomous, and artificial intelligence (AI)–based lifestyle coaching program on achieving blood pressure (BP) control among adults with hypertension was assessed. The study enrolled 141 participants who received a BP monitor and wearable activity tracker, with data collected from these devices and a questionnaire mobile app. Personalized machine learning models were trained using this data to enable precision lifestyle coaching delivered to participants via SMS text messaging and a mobile app. The primary outcomes included changes in systolic and diastolic BP from baseline to 12 and 24 weeks and the percentage change of participants in the controlled, stage-1, and stage-2 hypertension categories over the same period. Secondary outcomes encompassed participant engagement rate and the number of manual clinician outreaches.
The results revealed significant reductions in systolic and diastolic BP at both 12 and 24 weeks, with notable decreases observed, particularly for participants starting with stage-2 hypertension. The percentage of participants with controlled BP increased, while the percentage of participants with stage-2 hypertension decreased over the 24 weeks. Additionally, the average weekly participant engagement rate was 92%, and only a small proportion of participants required manual outreach, indicating high engagement and minimal clinician workloads.
In conclusion, the study demonstrated the potential of fully digital, autonomous, and AI-based lifestyle coaching to achieve meaningful BP improvements and high engagement for patients with hypertension. These findings suggest the promise of leveraging digital and AI technologies to address the challenges associated with traditional manual lifestyle coaching models while reducing the burden on clinicians.
