本研究报告分析了宁夏5160名35岁以上市区居民的高血压干预实验结果。分干预组2552人和对照组2608人。对干预组人群实施多种形式的防治高血压知识的宣传教育,并对高血压患者进行分级管理,定期随访,督促治疗等干预措施,而对照组只观察变化,不采取干预措施。结果显示:①干预组的收缩压和舒张压复查比基线时有所下降,而对照组都有所上升。②干预组确诊高血压的比例从基线时的19.47％降至复查时的16.66％,而对照组则从18.84％上升至24.21％。③在基线血压正常且以往无高血压史患者中,干预组确诊高血压的发病率分别为1.41％和0.7％,都低于对照组的1.99％和1.07％。④干预组高血压控制率,总有效率达92.2％。⑤干预组高血压并发脑卒中患者低于对照组。
