目的为了研究体检人群超重及肥胖情况，探讨心踝血管指数（CAVI）和血压分别与年龄以及体质指数（BMI）的关系，分析BMI在评价动脉硬化和高血压中的意义。方法选取2013年2—7月在安徽医科大学第一附属医院健康体检中心体检的941例体检人群为研究对象，运用统一的测量方法分别测量其身高及体重，根据公式计算出BMI，应用动脉硬化检测仪测出血压值与CAVI值，分别运用方差分析和多元Logistic回归分析对上述所得指标结果进行分析，并根据结果进行评价。结果①此次研究的体检人群中超重及肥胖情况严重，体检人群超重者占42．3％（398人），肥胖者占14．3％（135人）；②此次研究对象体检人群中，部分年龄组（41～70岁年龄组）收缩压随着年龄递增而上升（P〈0．01），部分年龄组（18～50岁年龄组）舒张压随着年龄递增而上升（P〈0．05）；③此次研究对象体检人群中，全年龄组CAVI值随着年龄递增而明显增高；④此次研究对象体检人群中，少数年龄组（31～50岁年龄组）CAVI值随着BMI值增大而下降（P〈0．05）；⑤研究对象体检人群中，多数年龄组（18—60岁年龄组）收缩压和舒张压随着BMI值增大而明显上升（P〈0．05）；⑥多因素分析显示，此次研究对象体检人群年龄、血压与CAVI呈正相关（P〈0．05），BMI与CAVI无明显相关性（P〉0．05）。结论此次研究对象体检人群中超重和肥胖形势严峻；研究对象体检人群中年龄对血压有一定的影响，而年龄则与CAVI呈现明显的正相关；研究对象体检人群中BMI与血压呈明显正相关，而BMI与CAVI则无明显相关性；BMI并不能够作为准确反映动脉硬化的指标。

英文摘要：

Objective To study the situation of overweight and obesity and explore the relationship between cardio-ankle vascular index（CAVI） and blood pressure with age and body mass index（BMI） in health examination population, analy- zing the significance of BMI in the evaluation of arteriosclerosis and hypertension. Methods To choose the 941 health examination people at the Health Examination Center from the First Affiliated Hospital of Anhui Medical University be- tween February,2013 and July,2013, to calculate their BMI by measuring the height and weight of this 941 health exami- nation people and detect CAVI and blood pressure by using arteriosclerosis detector,analysis the indexes above by using analysis of variance and Logistic analysis, then do an evaluation according to the resuhs. Results ①In these cases, the situation of overweight and obesity is serious, the rate of overweight is 42.3% （398 cases ）and the rate of obesity is 14.3 % （ 135 cases）. ②Systolic blood pressure in some age groups （41 - 70 age group） increased （ P 〈 0.01 ） , diastolic blood pressure in some age groups（ 18 -50 age group） increased（ P 〈 0.05 ）along with age increasing in these cases. ③ CAVI increased significantly in all age groups along with age increasing in these cases. ④Among these people, CAVI de- creased along with BMI increasing in some age groups （31 -50 age group） ,P 〈 0.05. ⑤Both systolic blood pressure and diastolic blood pressure increased significantly in most of these age groups（ 18 - 60 age group） along with the BMI increas- ing（ P 〈 0.05 ）.⑥Multiple factors analysis shows that CAVI presents a positive relationship with age and blood pressure （ P 〈 0. 05 ）, but has no relationship with BMI （ P 〉 0.05 ）. Conclusion The situation of overweight and obesity is seri- ous;age has a certain influence on blood pressure,but presents a positive relationship with CAVI;BMI presents a positive relationship with blood pressure,but has no relationship with CAVI;BMI
