Who is at risk for sarcoidosis?
Sarcoidosis occurs worldwide but most frequently among African–Americans and northern Europeans, and it affects slightly more women than men. It typically appears in the third or fourth decade of life, with a second peak in the sixth decade, especially among women. There is a higher prevalence of disease in first-generation relatives of those with sarcoidosis. Obesity may be associated with a higher risk of sarcoidosis. The disease is less likely to occur in people who smoke cigarettes.
