The NIH IMPROVE Act authorizes continued funding for a maternal health research initiative housed within the National Institute of Child Health and Human Development. The program focuses on reducing preventable maternal deaths and severe pregnancy-related complications, with particular emphasis on addressing racial, ethnic, geographic, and socioeconomic disparities in maternal health outcomes. The initiative will support research into the biological, behavioral, sociocultural, and structural factors affecting maternal health, including studies on cardiovascular disease, infection, nutritional deficiencies, and mental health issues during pregnancy and postpartum periods. The bill authorizes $53.4 million annually for fiscal years 2025 through 2031 to support grants, contracts, and cooperative agreements, including those with researchers from underrepresented minority groups. This legislation ensures sustained federal investment in addressing one of the nation's most pressing public health challenges, particularly for vulnerable and underserved populations.
