Minimal research has been performed to define differences in frequency and symptoms between races. One study, the National Health and Nutrition Examination Survey III (NHANES III), found that dysthymia is more common among African Americans and Mexican Americans than among Caucasians. [10]

For major depressive disorders, females outnumber males, with a female-to-male ratio of 2:1 during their childbearing years. Before puberty and after menopause, the 2 sexes appear to be affected about equally. In elderly people, dysthymia is relatively more frequent in females, but dysthymia adversely affects survival in males more than in females.
