The "Momnibus Act" aims to comprehensively address maternal health concerns in the United States. It seeks to improve maternal health equity through sustained funding and policy changes, extending WIC eligibility, and providing respectful maternity care training. The bill focuses on addressing bias, racism, and discrimination in maternity care settings and improving maternal health outcomes. It also aims to diversify the perinatal and nursing workforce, improve maternal health data collection, address disparities in care for minority groups, and protect pregnant and postpartum incarcerated individuals, among other measures. Additionally, the bill includes various grant programs to promote diversity, address mental health equity, and study maternal mortality among racial and ethnic minority groups. Furthermore, it prioritizes areas with high maternal mortality rates and aims to address climate change risks for vulnerable individuals, especially mothers and babies.
