辽宁农村中老年人群理想心血管健康现状及其与脉压的关系

Ideal cardiovascular health status of middle-aged and elderly people in rural Liaoning and its relationship with pulse pressure

目的探讨辽宁农村中老年人群理想心血管健康评分(ICHS)和脉压(PP)之间的关系,并对PP的影响因素加以研究,为动脉硬化的防治提供证据。方法选取2019年10月—2020年12月辽宁省锦州市北镇市农村年龄在50~80岁之间的当地居民共952例为研究对象进行描述性研究。采用标准化调查问卷采集受试者的人口统计学特征、生活方式、既往疾病史、用药史等资料。对受试者的身高、体质量和血压等进行测量,检测总胆固醇、空腹血糖(FBG)等生物化学指标。并对所有受试者进行ICHS评分。将研究对象按照PP高低分为PP正常组(n=521)和PP升高组(n=431),统计分析各变量在两组之间的差异;再对样本进行倾向性评分匹配,使两组受试者具有可比性,分析两组间各变量的差异及PP的影响因素。结果与PP正常组相比,PP升高组的ICHS较低,心血管健康水平较差,差异有统计学意义(P=0.005);血压(P<0.001)和FBG(P=0.033)也与PP密切相关。多因素Logistic回归分析结果表明ICHS为PP的独立影响因素,理想的ICHS是PP的保护因素(OR=0.55,95%CI:0.37~0.82,P=0.003)。并且教育程度较高、女性以及不经常饮酒的人具有较高的ICHS,即较理想的心血管健康水平(均P<0.05)。结论在辽宁农村中老年人群中,PP增大人群的ICHS显著低于PP正常人群,理想的ICHS是PP的保护因素。女性、教育程度较高以及不经常饮酒的人具有较理想的心血管健康状态。

Aim To explore the relationship between ideal cardiovascular health score(ICHS)and pulse pressure(PP)in rural middle-aged and elderly people in Liaoning Province,and to study the influencing factors of PP,so as to provide evidence for the prevention and treatment of arteriosclerosis.Methods A total of 952 rural residents aged between 50 and 80 in Beizhen City,Jinzhou City,Liaoning Province from October 2019 to December 2020 were selected as the research objects for descriptive research.A standardized questionnaire was used to collect the subjects demographic characteristics,lifestyle,past disease history,medication history and other data.The height,body mass and blood pressure of the subjects were measured,and the biochemical indexes such as total cholesterol and fasting blood glucose(FBG)were detected.All subjects were scored with ICHS.The subjects were divided into normal PP group(n=521)and elevated PP group(n=431)according to the level of PP,and the differences of variables between the two groups were statistically analyzed;Then the samples were used by propensity score matching to make the two groups of subjects comparable,and the differences of variables between the two groups and the influencing factors of PP were analyzed.Results Compared with normal PP group,the ICHS was lower and the cardiovascular health level was poor in elevated PP group,the difference was statistically significant(P=0.005).Blood pressure(P<0.001)and FBG(P=0.033)were also closely related to PP.Multivariate Logistic regression analysis showed that ICHS was the independent influencing factor of PP,and ideal ICHS was the protective factor of PP(OR=0.55,95%CI:0.37~0.82,P=0.003).Higher education level,women and people who didn t drink often had higher ICHS,that was,an ideal cardiovascular health level(all P<0.05).Conclusions In Liaoning rural middle-aged and elderly population,the ICHS of PP increasing population is significantly lower than that of PP normal population,and the ideal ICHS is the protective factor of PP.Women,people with higher education and people who don t drink often have better cardiovascular health.
