How common is depression during pregnancy?

Pregnancy can be a time of joy — and stress. Research suggests that about 7% to 9% of pregnant people in high-income countries such as the United States have depression during pregnancy. Rates might be higher in low- and middle-income countries.

What's more, some pregnant people with depression don't learn that they have the mood disorder. Healthcare professionals may spot, also called diagnose, depression less often in pregnant people compared to those who aren't pregnant. They also may diagnose depression during pregnancy less often than postpartum depression.
