AGE AND SEX OF PATIENTS WITH GCA:

The age ranged from 56 years to 93.4 years (median 75.8 years).¹ Thus, GCA is a disease of middle-aged and elderly persons and not of young persons. Epidemiological studies have shown that the higher the age, the greater the prevalence of GCA. One such study showed that in persons aged 60-69 years the prevalence is 33 per 100,000 persons; in those over 80 years old, 843 per 100,000.

Sex distribution in our study was 27.4% men and 72.6% women. Thus, GCA is seen far more frequently in women than in men.

There is evidence that GCA is far more common among Caucasians than other races.⁷ These racial differences suggest a genetic predisposition for development of GCA.
