Is military deployment a risk factor for maternal depression?

Area of Science:

• Military Health
• Maternal Mental Health
• Psychiatry

Background:

• Maternal depression is prevalent in new mothers, impacting maternal and infant well-being.
• Research on maternal depression among military mothers is limited, despite unique stressors.
• This study investigates deployment experiences and maternal depression in U.S. service women.

Purpose of the Study:

• To examine the prospective relationship between deployment experiences and maternal depression.
• To identify specific deployment factors associated with increased depression risk in military mothers.
• To differentiate the impact of combat exposure versus childbirth on maternal mental health.

Main Methods:

• Utilized data from 1,660 female Millennium Cohort participants who gave birth during active duty.
• Collected data via questionnaires between 2001 and 2008.
• Assessed maternal depression using Primary Care Evaluation of Mental Disorders Patient Health Questionnaire criteria at follow-up.

Main Results:

• Deployment before or after childbirth without combat did not elevate depression risk.
• Women deployed with combat experience after childbirth showed increased maternal depression risk (aOR 2.01).
• No significantly increased depression risk was observed for women who gave birth among female combat deployers.

Conclusions:

• Post-childbirth deployment with combatlike experiences increases maternal depression risk in military women.
• The primary driver of increased depression risk appears to be combat exposure, not childbirth.
• Findings highlight the need for targeted mental health support for deployed service women.
