Answer

IgA nephropathy is more common in Asians and whites and is rare in blacks, both in the United States and in Africa. The condition is frequently observed in Native Americans of the Zuni and Navajo tribes.

IgA nephropathy is more common in males than in females. Virtually all studies show a male predominance of at least 2:1, with reported ratios of up to 6:1. [11] The higher male predilection is observed in white patients in northern Europe and the United States.

IgA nephropathy can affect all ages but is most common in the second and third decades of life. Eighty percent of patients are aged 16-35 years at the time of diagnosis. The condition is uncommon in children younger than 10 years.
