目的测量某校男生肾下腹主动脉直径(IRAD)及髂总动脉直径(CIAD),并探讨相关因素与动脉直径的关系.方法 2013年5-6月采用横断面研究方法,以北京市昌平区某技工学校203名男生为研究对象,使用超声测量动脉直径,并对与动脉直径相关的因素进行线性回归分析.结果研究对象年龄为18 ～ 28岁,平均年龄21.5岁.IRAD为(13.4± 1.9)mm,CIAD为(9.4±1.6)mm,两侧CIAD大小无明显差异.多元线性回归分析结果显示,IRAD与腰围呈正相关(P=0.03),与饮酒呈负相关(P=0.04);CIAD与年龄、臀围呈正相关(P =0.00、0.04),与收缩压、饮酒呈负相关(P=0.01、0.00);未发现吸烟与IRAD或CIAD有相关性.结论该人群IRAD及CIAD较国外老年人群偏小,年龄、腰围、臀围、饮酒等因素与动脉直径相关,但上述因素对动脉直径的效应很小.

Objectives To establish the ultrasonographic criteria for normal size of infrarenal aorta (IRA) and common iliac arteries (CIA) of young males in a Chinese school and to determine the associations between IRA diameter (IRAD) and CIA diameter (CIAD) and body habitus as well as traditional cardiovascular risk factors.Methods Cross-sectional study was done of 203 Chinese young males enrolled from a technical school in Beijing Changping district from May to June 2013.The IRA and CIA scans were carried out using ultrasonography.Longitudinal scans were used to assess aortic morphology and tortuosity.The maximum internal anteroposterior IRAD and CIAD in any area of the arteries were measured during the cardiac cycle.Participants information on demographic,medical history,smoking history and alcohol consumption was obtained through unified questionnaire.Univariate and multivariate linear regression was used to determine the associations between arterial diameter and body habitus as well as other risk factors.Results The median participants age was 21.5 (ranging from 18 to 28) years.The IRAD was (13.4 ± 1.9) mm,and the CIAD was (9.4 ± 1.6) mm.There was no significant difference between the left and right CIAD.Waist circumference was significantly associated with increasing IRAD (P =0.03),while alcohol had an inverse correlation (P =0.04).Age,hip circumference were significantly associated with increasing CIAD (P =0.00,0.04),while the systolic pressure and alcohol had inverse correlations (P =0.01,0.00).By dividing the entire group into equal four groups using quartile values for both age and waist/hip circumference,the older group and the larger waist/hip circumference had greater arterial diameter.Conclusions The enrolled Chinese young males have smaller IRAD and CIAD compared with foreign older population.Age,waist circumference,hip circumference,alcohol and systolic pressure have statistically significance but small effects on arterial diameter.
