[Determination of age based on the circumference of the aorta]

In a cohort of 207 men at the age of 16 to 85 years and 140 women at the age of 16 to 94 years a very close relationship between age and circumference of ascending part, aortic arch and abdominal aorta was found. The coefficient of multiple correlation of age with the size of aorta was 0.896 in women; residual standard deviation was 6.67 years in men and 8.15 years in women. The relationship between age and the size of aorta was expressed by regression liner equation for each sex separately. The age was calculated by means of this equation and the best results were reached in both sexes in the range of 26 to 65 years. In this age period a deviation greater than 10 years from the real age occurred in the least frequency. In the whole cohort of men this deviation occurred in 21.7% and in the whole cohort of women in 22.8% of persons.
