American Moms Don’t Recover From Postpartum Depression. Moms in Other Countries Do.
A study of 31,500 mothers across the United States, the United Kingdom, and Australia found that women in the U.S. see their postpartum depression symptoms barely improve over five years. Women in the U.K. and Australia recover. The difference is not biological. It is structural.
Researchers tracked depressive symptoms from pregnancy through the first five years of a child’s life. In all three countries, symptoms were highest in the newborn period. In the U.K. and Australia, they declined steadily. In the U.S., they did not. American mothers were still reporting elevated symptoms at the five-year mark, a timeline that far exceeds what most people understand postpartum depression to mean.

This is a meaningful reframing. Postpartum depression is typically discussed as a medical condition that emerges from hormonal shifts after birth, requires clinical treatment, and resolves over months. That framing applies to many women. It does not explain why American mothers are still struggling at year five when their counterparts in comparable wealthy countries are not.
The study also complicates the narrative that postpartum depression is primarily about the newborn period. If symptoms in the U.S. persist through early childhood, then the interventions needed are not just clinical screenings at the six-week checkup. They are policy interventions: leave, childcare access, and mental health infrastructure that lasts longer than the maternity ward.
None of this means individual treatment does not matter. It does. But a country cannot screen its way out of a structural problem. The data from 31,500 women in three countries suggests the U.S. has been trying to do exactly that.
