Maternal Health, including mental health, is an urgent concern of policy makers, clinicians and researchers. Please join us on December 2, 2019 for a critical discussion on the intersection between maternal health and women’s mental health across the life course. The discussion is designed to drive change on this very important issue. This stakeholder meeting will build on the March 2018 Committee on Population workshop, Women’s Mental Health across the Life Course through a Sex-Gender Lens, sponsored by the Office of Women’s Health at the U.S. Department of Health and Human Services. The stakeholder event will focus on research gaps and policy/practice implications of the research, with particular attention to maternal mental health. National experts will present how factors from adolescence through later life shape women’s mental health trajectories. There will be an emphasis on research, data, programs and policies needed to provide the evidence for sound policy and practice recommendations. Maternal mental health impacts health across the life course and requires special focus. This meeting will be a call to action for vital policy and research reform in maternal mental health.
