The National Institutes of Health (NIH) is inviting applications for a federal grant focused on implementation research addressing noncommunicable disease (NCD) risk factors among low- and middle-income countries (LMICs) and American Indian/Alaska Native (AI/AN) populations living in urban environments. The initiative aims to develop innovative strategies for overcoming barriers to the adoption and sustainability of evidence-based interventions, with a particular emphasis on understanding the impact of environmental factors such as pollution and health access on NCDs. This funding opportunity is crucial for promoting health equity and improving global health outcomes by equipping policymakers with effective prevention and management strategies tailored to disadvantaged populations. Interested applicants must submit their proposals by March 11, 2024, and can find additional information and guidelines at the NIH grants website or contact NIH Grants Information at grantsinfo@nih.gov.
