The Department of Health and Human Services, through the National Institutes of Health, has issued a funding opportunity titled "Interventions to Reduce Sleep Health Disparities" to support innovative projects aimed at promoting sleep health and addressing sleep-related health inequalities. This initiative invites applications focused on non-pharmacological interventions targeting diverse populations experiencing health disparities, particularly in sleep deficiencies and related health outcomes, such as mental health and chronic diseases. The funding opportunity emphasizes the importance of understanding the multi-level determinants — biological, social, and behavioral — affecting sleep health disparities. Prospective projects should aim to improve sleep health through community-engaged research and targeted interventions, particularly among historically marginalized groups, including racial and ethnic minorities, sexual and gender minorities, and low socioeconomic populations. Key dates include an application submission period starting January 5, 2025, with specific deadlines for merit review and funding decisions extending until September 8, 2027. Eligible applicants encompass a variety of organizations, including educational institutions, nonprofits, and government entities. The overall goal of this funding initiative is to enhance sleep quality and mitigate disparities, aligning with broader public health objectives aimed at improving health equity in the U.S.
