摘　　要：高血压是常见的心血管疾病,针对引起血压显著变化的影响因素开展深入研究对预防高血压及其并发症均具有重要意义.为此,根据11624个样本数据,选用Group Bridge方法对血压及其年龄、文化程度等8组共35个影响因素进行拟合分析.结果显示:Group Bridge方法能够提供科学有效的稀疏拟合结果;拟合结果共选定6组中的18个影响因素,其中存在正向影响关系的因素15个,负向影响关系的因素3个;综合考虑影响因素数量和强度,发现体格方面的影响因素对血压的影响最为重要,其次是体脂指标及生活方式和行为方面,再次为疾病家族史、年龄及文化程度,最后是婚姻状况及收入水平.Hypertension is a common cardiovascular disease.In-depth research on factors causing significant changes in blood pressure for play an important significance in the prevention of hypertension and its complications.In this paper,based on 11,624 sample data,Group Bridge was used for analyzing blood pressure and eight groups and a total of 35 factors of blood pressure including：age,educational level,etc.The results showed：Group Bridge can provide effective sparse fitting results;fitting results of the six groups selected18 factors,including 15 factors have positive influence to blood pressure and 3 factors which negative influence to blood pressure.Considering the number and intensity of factors,we can find physical aspects have most influence on blood pressure,the second body fat index and lifestyle and behavior,thirdly,again as a family history of the disease,age and education level,and the final was marital status and income level.
