The National Institutes of Health (NIH) is offering a grant opportunity titled "Implementation Research on Noncommunicable Disease Risk Factors among Low- and Middle-Income Country and Tribal Populations Living in City Environments (R01 Clinical Trial Optional)". This grant aims to support implementation research focused on addressing risk factors for common noncommunicable diseases (NCDs) in low- and middle-income countries (LMICs) and American Indian/Alaska Native (AI/AN) Tribal Nation populations in the United States. The grant seeks innovative approaches to identify, understand, develop, and implement strategies for overcoming barriers to the adoption, adaptation, integration, scale-up, and sustainability of evidence-based interventions, tools, policies, and guidelines. It also encourages studies to advance dissemination and implementation research methods and measures into application. Specifically, this grant invites applications that propose implementation research targeted at reducing the risks of NCDs in the context of cities in LMICs and/or among AI/AN Tribal Nation populations in cities in the United States. The ultimate goal is to equip policymakers and practitioners with evidence-based strategies for the prevention and/or management of NCDs among disadvantaged populations globally. The grant does not require cost sharing or matching requirements and is open to various eligible applicants, including Alaska Native and Native Hawaiian Serving Institutions, Asian American Native American Pacific Islander Serving Institutions (AANAPISISs), Eligible Agencies of the Federal Government, Faith-based or Community-based Organizations, Hispanic-serving Institutions, Historically Black Colleges and Universities (HBCUs), Indian/Native American Tribal Governments (Other than Federally Recognized), Non-domestic (non-U.S.) Entities (Foreign Organizations), Regional Organizations, Tribally Controlled Colleges and Universities (TCCUs), and U.S. Territory or Possession.
