44.9 cases per 1,000 person-years

The "incidence rate" of postpartum depression (PPD) among "126,006 primiparous (active duty) service women without histories of previous mental health diagnoses" between 1998 and 2010, according to a study in the June issue of the Medical Surveillance Monthly Report, a publication of the Armed Forces Health Surveillance Center.

In the study -- Risk of Mental Health Disorders Following an Initial Diagnosis of Postpartum Depression, Active Component, U.S. Armed Forces, 1998–2010 

-- the researchers note that those diagnosed with PPD were at higher subsequent risk of depressive, anxiety and bipolar disorders.  Also, according to the researchers:

Those active component females who do experience PPD have a 42.2-fold increased adjusted odds of having suicidality in the postpartum period when compared to service women without PPD.13 Furthermore, deployment less than 6 months after delivery confers a 37% increased risk of mental health issues within 6 months of redeployment when compared to postpartum active component military mothers who were deployed much later, suggesting that the peripartum period may confer additional risk for mental health issues.
