Overview
This is a 1:1 parallel design, multi-center, cluster-randomized control trial. A total of 80 villages in Ruyang County, Henan Province, China, will be randomly assigned to the intervention group or control group. At least 100 participants from 30-50 families in each village will be included in this study. The intervention group will engage in a variety of strategies, including adopting a low-sodium diet, managing weight, participating in physical exercise, monitoring blood pressure, and undergoing antihypertensive treatment. These efforts will be led by healthy family instructors from the community. The control group will receive usual care. The primary endpoint of this study is the change of systolic blood pressure from baseline to 6 months, reported as the difference between intervention and control group.
Description
This cluster-randomized control trial aims to randomly allocate 80 villages in Ruyan County to either receive a multifaceted intervention led by family healthy instructors or continue with usual care. Each village will recruit around 100 individuals aged 40-80 years, with or without hypertension. In intervention villages, a blood pressure management team, headed by healthy family instructors and family leaders, will implement various strategies including promoting a low-sodium diet, weight management, physical exercise, blood pressure monitoring, and administering antihypertensive treatment. The intervention will span 6 months, followed by another 6-month follow-up period. The primary hypothesis posits that the mean systolic blood pressure change from baseline to 6 months will be higher in the intervention group compared to the control group. The objective of this "Health Family Program" is to evaluate the efficacy of a non-healthcare provider-led multifaceted intervention in enhancing healthy lifestyles and managing blood pressure among rural residents, regardless of their hypertension status, in China.
