Although existing epidemiologic studies are limited because they have been performed on predominantly white populations, the results of these studies suggest that GCA primarily affects whites, specifically those of northern European descent. Scandinavians have the highest prevalence. GCA is less common in African Americans and Asians. [39] Although GCA had been considered less common among Hispanic persons, [40] recent evidence has challenged this notion.
