Plain English Summary
Background and study aims
The disease burden of hypertension (high blood pressure) in China has been increased rapidly, and long-term effective prevention strategies are needed to prevent and control hypertension in China. This is a 2-year community-based study in two communities in Shanghai, China with the support of the local government. The aim of this study is to find out whether a community-based comprehensive intervention strategy of blood pressure control is effective.
Who can participate?
People aged 35 to 74 living in two selected communities in China
What does the study involve?
All participants in the intervention community receive comprehensive interventions, including health education and lifestyle interventions, including reducing intakes of dietary sodium, decreasing body weight, and increasing physical activity. In addition, the hypertensive patients in the intervention community are managed with hypertensive drug treatment to control blood pressure and followed up by the community physicians regularly. Participants in control community do not receive any intervention provided by the investigators of this study.
What are the possible benefits and risks of participating?
The participants would not have any direct benefit from the study, but the study may contribute to the prevention and control of blood pressure in China. When the participants had physical examinations, they may feel uncomfortable. For example, sphygmomanometer cuff inflation for blood pressure measurement may cause discomfort. In addition, the participants may feel short-term discomfort when blood is drawn. There is a small possibility of infection, excessive bleeding, clotting or fainting. If the participants are injured as a result of participating in this study, medical treatment is provided by the researchers.
Where is the study run from?
1. Bansongyuan Community (China)
2. Nanjing East Road Community (China)
When is the study starting and how long is it expected to run for?
May 2007 to December 2010
Who is funding the study?
National Science and Technology Support Projects for the Eleventh Five-Year Plan of China

The study was a non-randomized controlled intervention program, and two well-organized communities, in which the population was relatively stable and health records of the participants were accessible, were selected as our survey sites.
All participants in the intervention community received health education to improve hypertension-related knowledge. Lifestyle interventions including reducing intakes of dietary sodium, decreasing body weight, and increasing physical activity were offered to all participants in the intervention community. Whole community fitness program was launched in the intervention community to encourage residents to participate in physical exercise. Also, cardiovascular and cerebrovascular diseases specialists provided on-site counseling and guidance on healthy lifestyle. In addition, the hypertensive patients in the intervention community were managed to have hypertensive drug treatment to control blood pressure and followed up by the community physicians regularly. Participants in control community did not receive any intervention provided by the investigators of this project. The total duration of the intervention and follow-up was 2 years.
Primary outcome measure
Systolic blood pressure, measured by trained staff using a conventional mercury sphygmomanometer and appropriately sized cuffs after a 5-minute rest in the seated position, at baseline and the endpoint of the study
Secondary outcome measures
Diastolic blood pressure, measured by trained staff using a conventional mercury sphygmomanometer and appropriately sized cuffs after a 5-minute rest in the seated position, at baseline and the endpoint of the study
