Paternal Postpartum Depression
It turns out, at least in this paper, that prenatal and postpartum depression happens to about 10% of men, and is most common about 3 to 6 months after the babies arrive. This compares to a rate of about 24% for maternal depression in the same study data, and a general national population rate for depression of about 5% for men in any given 12-month period.
The researchers warn that their findings suggest more questions than provide answers. But it seems that significantly more fathers experience depression before or shortly after their babies' birth. And the authors conclude with a nice ESP-like statement: "Future research in this area should focus on parents together to examine the onset and joint course of depression in new parents."
