In order to determine the relevance of abdominal aortic dilatation, knowledge of the normal aortic diameter and its relation to age, sex and body size (height, weight, body surface area) is essential. The diameter of the infrarenal aorta was measured in 146 healthy males and females 4-74 years old with ultrasonography and the influence of the aforesaid factors on aortic diameter was analysed by means of a multiple stepwise regression model. The infrarenal aorta was found to increase steadily in diameter throughout life. From about 25 years the diameter was larger in males than in females (p < 0.01) though this difference vanished if corrected for differences in body surface area. Significant correlations were found between aortic diameter and weight (r = 0.84, p < 0.001), height (r = 0.77, p < 0.001) and body surface area (r = 0.83, p < 0.001). Age followed by body surface area were the factors most influencing aortic diameter in both males (r = 0.92, p < 0.001) and females (r = 0.94, p < 0.001). Nomograms predicting aortic diameters in relation to age, sex, and body surface area are presented.
为了确定腹主动脉扩张的相关性，了解正常主动脉直径及其与年龄、性别和身体大小（身高、体重、体表面积）的关系至关重要。采用超声检查测量了146名4至74岁健康男性和女性的肾下腹主动脉直径，并通过多元逐步回归模型分析了上述因素对主动脉直径的影响。结果发现，肾下腹主动脉直径在一生中稳步增加。从大约25岁起，男性的主动脉直径大于女性（p < 0.01），不过如果校正体表面积差异，这种差异就会消失。主动脉直径与体重（r = 0.84，p < 0.001）、身高（r = 0.77，p < 0.001）和体表面积（r = 0.83，p < 0.001）之间存在显著相关性。在男性（r = 0.92，p < 0.001）和女性（r = 0.94，p < 0.001）中，年龄其次是体表面积是最影响主动脉直径的因素。本文给出了根据年龄、性别和体表面积预测主动脉直径的列线图。
