Opportunities to advance implementation science and nutrition research: a commentary on the Strategic Plan for NIH...

Despite population-wide recommendations by the U.S. Dietary Guidelines for Americans and others to encourage health-promoting dietary patterns, the proportion of Americans following dietary recommendations remains low. The gaps in the adoption and integration of evidence-based dietary interventions, practices, programs, and policies (EBIs) into community and clinical settings signal the need to strengthen efforts in implementation science (IS) in nutrition research to understand and alleviate barriers to adopting and sustaining healthy dietary behaviors and practices. Equally important is the translation of this research into practice in a variety of settings and across the diversity of populations. Recognizing this need, the U.S. National Institutes of Health (NIH) 2020-2030 Strategic Plan for NIH Nutrition Research calls for the expansion of IS as a key opportunity to advancing nutrition research. This commentary highlights three scientific opportunities to stimulate IS in nutrition research and provides examples for each opportunity. These include: (a) Advance consideration of implementation and dissemination early in the design of interventions to facilitate opportunities for equitable scale-up and sustainability of EBIs, (b) Develop and test strategies for equitable implementation of nutrition and diet EBIs in health care and community settings, and (c) Build and strengthen the infrastructure, capacity, and expertise needed to increase use of IS in clinical and community nutrition research to swiftly move the research into practice. By advancing the three opportunities identified in this commentary, the scientific community has the potential to advance the field of nutrition research and IS with the ultimate goal of improving public health.
