The National Institute on Aging (NIA) has awarded a $441,358 Project Grant under CFDA 93.866 - Aging Research to the Regents of the University of Minnesota, doing business as the Office of Sponsored Projects Administration. This 5-year grant will fund the Interdisciplinary Network on Rural Population Health and Aging (INRPHA), a research collaboration focused on enhancing understanding of the multilevel and multidimensional factors affecting the health, functioning, and mortality outcomes of U.S. rural working-age and older adults. Key aims of the INRPHA project include conducting research to elucidate within-rural heterogeneity in health and aging trends, strategically growing the network to include diverse disciplinary perspectives, providing training and development opportunities for network members, and advancing the dissemination of research findings to inform policies and programs related to rural population health and aging. This project builds on the successes of INRPHA's prior 5-year funding period and will leverage existing NIH data resources to drive innovative, publicly accessible research on this critical topic.
