The National Institutes of Health (NIH) has announced a funding opportunity titled "NIDA REI: Reaching Equity at the Intersection of HIV and Substance Use," aimed at addressing health disparities related to HIV and substance use among underserved racial and ethnic populations. This initiative encourages innovative observational and intervention research that examines structural factors and social determinants contributing to these inequities, with a focus on ensuring that at least 50% of study participants come from designated minority populations. The NIH is offering approximately $3,000,000 in funding for FY 2023, with plans to make 5-9 awards, and applicants must submit a "Plan for Enhancing Diverse Perspectives" to promote inclusivity in their research. Interested parties can find more information and contact NIH Grants Information at grantsinfo@nih.gov, with key deadlines including a close date for applications on November 14, 2024.
