Abstract: Objective The project of hypertension control in communities（HCC） aimed to determine the effect of standardized community-based management on control of hypertension.Methods The protocol of standardized community-based hypertension management was developed by expert board with being oriented by 2005 guidelines for prevention and treatment of hypertension in China.Community health service centers across China were selected to implement the protocol.After trained with the protocol,the primary care physicians from selected centers were asked to manage hypertensives using the protocol.The control of hypertension was evaluated after 1 year.Results By the end of 2008,there were 110 610 patients with eligible baseline data for analysis,47.7% were male.The mean entry systolic/diastolic blood pressure was（145.5±17.3）/（88.3±10.7） mmHg,about 31.5% patients like to eat highly seasoned food,17.1% drink,18.5% smoke.Prevalence was higher in male than in female（P＜0.05）.Grade 1,grade 2,and grade 3 hypertension were 47.1%,22.4% and 8.1%;low-,moderate-,and high-risk group were 9.4%,53.9% and 36.7%,respectively.At entry,75.7% were treated and 22.5% were under controlled（＜140/90 mmHg）.Conclusion The baseline characteristic of HCC subjects were described in this article.It showed that a standardized management protocal might improve the control rate of hypertension.
