Women are four times more likely to experience SAD than men, the NIMH reported. SAD is also more frequently diagnosed in those who live far north or south of the equator. "People with a family history of other types of depression are more likely to develop SAD than people who do not have a family history of depression," the NIMH reported on its website. Finally, younger adults have a higher risk of SAD than older adults, according to the NIMH.
