目的研究辽宁省彰武县农村人群脉压等血压相关指标与脑卒中的关系。方法应用随机抽样的方法对辽宁省彰武县5 208人进行一般情况、血压、脑卒中患病情况的调查并进行统计学分析。结果脑卒中组与非卒中组按照脉压水平分级后,其组间差别有显著意义(P<0.01),脑卒中组男女脉压分布趋势一致。30岁后各年龄组按照脉压水平分级后,脑卒中组与非卒中组组间差异明显(P<0.05)。收缩压、舒张压、脉压、平均动脉压两组间均存在显著差异(P<0.01)。随脉压的增大,脑卒中OR值增加。结论此地区人群脑卒中患病率与脉压具有明显的相关性,而且患病危险性随脉压增高而增加。不同性别间无明显差别。
Objective To study the relationship between blood pressure-related indexes such as pulse pressure and stroke in rural population in Zhangwu County of Liaoning Province. Methods A total of 5 208 people in Zhangwu County of Liaoning Province were surveyed by random sampling method for the general situation, blood pressure and stroke prevalence and statistical analysis. Results There was significant difference between the two groups (P <0.01). The distribution of pulse pressure in stroke group was consistent with that in non-stroke group. After 30 years of age in all age groups graded according to pulse pressure level, the difference between the stroke group and the non-stroke group was significant (P <0.05). Systolic blood pressure, diastolic blood pressure, pulse pressure, mean arterial pressure were significantly different between the two groups (P <0.01). As the pulse pressure increases, the OR value of stroke increases. Conclusions The prevalence of stroke in this population is significantly correlated with pulse pressure, and the risk of illness increases with increasing pulse pressure. No significant difference between different genders.
