简要总结
In this pilot RCT, a total of 40 adults with hypertension will be randomized to either an artificial intelligence (AI) physical activity intervention group or an active control group with a 1 to 1 ratio after completing a 2-week run-in period and 4-week training. The AI intervention group will receive an automated and personalized daily step goal intervention involving a sophisticated activity analytics algorithm using advanced statistics and machine learning, while the active control group will receive a standardized and fixed 10,000 daily steps goal. Both groups will receive an identical smartphone app (app content differs between the two groups) and ActiGraph GT9X Link to assess objectively measured physical activity (primary outcome) during the study period.
