Lupus affects different age groups at
different rates. The majority of people with lupus develop the disease between
ages 15 and 45.1 Women account for 85% of diagnosed
lupus cases.2
Heredity is a factor,
meaning lupus sometimes runs in families. If a mother has lupus, her children
have a slightly increased risk of developing the disease.2
The number of people who have lupus varies
widely among different countries and among different populations within
countries. Lupus is present in as many as 1 out of every 250 black women; it is
present in 1 out of every 1,000 white women.2 Lupus
occurs more often in Hispanic, Native American, and Asian people than in
whites.1
