Abstract
Lateral roentgenograms of the lumbar spine from 1,463 ambulatory outpatients of the Department of Roentgenology of the Hadassah-Hebrew Hospital in Jerusalem were graded with respect to the degree of osteoporosis and aortic calcification. Aortic calcification increased in both sexes with an increase in age and to approximately the same degree, although men over the age of 60 showed somewhat more calcification than women of the same age. Many of the subjects were immigrants to Israel, but little effect of the area of origin upon the degree of aortic calcification could be proven. The association between the degree of osteoporosis and aortic calcification in both men and women over age 60 was highly significant, but this association is not explained by the fact that both disorders are age- dependent.
