Risk Factors
Seasonal affective disorder affects women four times more frequently than men and affects younger adults more than older adults. The most common age of onset is between 20 and 30 years.
The chances of developing SAD are increased by a family history of major depression and psychiatric disorders, as well as living within close proximity to either of the poles. As SAD corresponds to fewer daylight hours during winter, it occurs far less frequently in countries that experience year-round sunshine.
