Social Determinants for Moms Act This bill requires the Department of Health and Human Services (HHS) to establish a task force and a grant program to address social determinants of maternal health. The task force, composed of federal and nonfederal stakeholders, must develop strategies and coordinate efforts to eliminate preventable maternal mortality, severe maternal morbidity, and maternal health disparities. Additionally, HHS must award grants to community-based organizations, nonprofits, tribal organizations, public health departments, or consortia of these entities to address social determinants of maternal health and eliminate disparities in maternal health outcomes.
