A Cluster-Randomized Trial of a Hypertension Risk Model-Based Precision Intervention in High-Risk Adults in Shunyi District

This community cluster-randomized controlled trial aims to evaluate the effectiveness of a hypertension risk model-based precision intervention among adults at high risk of developing hypertension in Shunyi District, Beijing, China. Four community clusters are included in the trial and are allocated in a 1:1 ratio to either a precision intervention group or a control group, with two community clusters in each group. Eligible participants are adults aged 35 to 65 years who are identified as having a predicted hypertension risk greater than 20%, have not been diagnosed with hypertension, and are not taking antihypertensive medications. Participants in the intervention clusters receive individualized health management delivered through a WeChat mini-program and community healthcare providers, including personalized health education, behavioral goal setting and follow-up, blood pressure monitoring guidance, and health management tools. Participants in the control clusters receive standard, non-personalized health education and usual community health services. The primary outcomes are changes in systolic and diastolic blood pressure. Secondary outcomes include hypertension-related status, incidence of new-onset hypertension, changes in anthropometric measures, and hypertension-related knowledge and beliefs.
