高血压防治相关知识对患者血压控制状况的影响

目的 探讨城乡患者的高血压防治相关知识水平与高血压控制率的关系。方法 对北京市城乡4个社区卫生服务中心经常就诊的726名高血压患者进行问卷调查并测量血压。结果 城乡患者高血压控制(血压低于140／90mm Hg，1mm Hg=0．133kPa)率分别为46．4％和23．9％。城乡高血压控制率均随患者防治知识知晓的积分增加而升高，在城市具有统计学显著性。相关知识的差异可解释高血压控制率城乡的差异(30．0％)。结论 患者高血压防治知识水平对其高血压是否得到控制有显著影响。对患者普及高血压防治基本知识，可有效提高高血压的控制率。

Relationship between the patients' knowledge on hypertension prevention and control and the rate on blood pressure control

Objective To study the relationship between blood pressure control status and patients' knowledge on hypertension prevention and control among hypertensive patients. Methods A total of 726 hypertensives were selected from four community health service centers (2 urban and 2 rural) in Beijing. All subjects were investigated by questionnaires and their blood pressures were measured at the same time. Results The rate for blood pressure under control (<140/90 mm Hg,1 mm Hg=0.133 kPa) in the rural and urban patients were 46.4 % and 23.9 % respectively. The control rate increased with the increase of patients' knowledge on prevention and control of hypertension in both urban and rural patients. The cumulative effect of knowledge on hypertension control status could contribute 30.0 % to the difference in hypertension control rate between rural and urban patients. Conclusion Patients' knowledge on hypertension control was significantly related to the rate on hypertension control. Health education should be helpful to improve the rate on hypertension control.
