Nutrition Research Funding Trends and Focus Areas at the US National Cancer Institute

Evidence for diet and nutrition's role in the cancer continuum is inconsistent and requires further study. Although more investigation is needed, the National Cancer Institute (NCI) funding for nutrition has decreased.

To examine nutrition research funding at the NCI, a portfolio analysis was undertaken for fiscal year (FY) 2018. Nutrition and other cancer-related terms were searched using the National Institutes of Health Query View and Report grants management dashboard. Grants were categorized by mechanism, funding status, applicant characteristics, funding opportunity announcement type, award type, and study characteristics.

A total of 18 233 NCI grant applications were submitted in FY 2018; 12% were funded. Of the 653 nutrition-related grant applications received, 69 (11%) were funded. Funding status of nutrition grants did not differ statistically based on the type of funding opportunity announcement and were higher for applications classified as investigator initiated. Early stage investigators' nutrition applications were funded less than other investigators. Only 4% and 6% of overall and funded nutrition grant applications were submitted by registered dietitian nutritionist primary investigators, respectively. Average FY 2018 award amounts for funded nutrition and overall grant applications were approximately US $399 000 and approximately US $703 000, respectively. Although the percentage of NCI nutrition grants funded was similar to other grant funding at NCI in FY 2018, between FY 2012 and FY 2018, NCI decreased overall nutrition funding by 44%.

Average grant award amounts for nutrition were less compared with overall NCI-funded grant applications and other topics. Our analysis highlights potential opportunities for greater investment in nutrition research at the NCI.
