Background: Pilot project programs offer early-stage and other investigators support to pursue emerging research areas, explore new methodologies, gain experience as principal investigators, and collect pilot data needed to pursue larger extramural research funding, such as from the National Institutes of Health. Pilot project programs may be particularly important to early-stage investigators from underrepresented backgrounds, who must overcome unique challenges to launching careers in community-based participatory research. This paper describes the structure, function, and impact of the Native Center for Alcohol Research and Education (NCARE) Pilot Project Core. Methods: During four calls for applications from 2018 to 2021, research investigators interested in conducting alcohol use disorder research in partnership with Tribal communities were recruited, with a focus on early-stage and American Indian and Alaska Native investigators. Eligible investigators were required to submit letters of intent prior to preparing full applications, which underwent a rigorous review process. Results: Eight pilot projects were awarded. Of the eight pilot project investigators, seven were early-stage scholars, seven were female, and four identified as American Indian or Alaska Native. The funded projects included two primary areas of research, epidemiological studies and intervention projects. Once funded, the Pilot Project Core assisted pilot project investigators with securing approvals for their research studies, responding to methodological and analysis questions, and mentoring and monitoring their progress. At the time of writing this paper, three pilot project investigators have completed their pilot projects, three investigators are currently collecting data, and one is in the analysis phase. One pilot project investigator did not complete their project due to COVID-19 restrictions early in the pandemic. The pilot project investigators submitted 36 grant proposals for independent external funding and received 25 grants after funding of their pilot project; four were directly related to pilot project grants. Additionally, four peer-reviewed manuscripts resulting from Pilot Project Core support were published. Conclusions: Despite challenges related to the COVID-19 pandemic the pilot project funding through NCARE provided eight pilot grants, half of which identified as AI/AN and most of which led directly to multiple grants and papers. The NCARE pilot program provides a model for other similar programs seeking to support early-stage investigators who identify as AI/AN or other groups underrepresented in science.

We sought to evaluate the acceptability and feasibility of a culturally tailored food box intervention for improving blood pressure (BP), food security and Body Mass Index (BMI) among Chickasaw Nation adults with uncontrolled hypertension. As part of the Chickasaw Healthy Eating Environments Research Study (CHEERS), we administered a group randomized pilot study in four tribal communities (two intervention, two control). Participants in the intervention communities received six heart-healthy food boxes, culturally tailored to traditional Chickasaw diet and current food context. Outcomes were measured over 6 months. We enrolled 262 participants, and 204 with complete data on key variables were included in the analysis. The food boxes were very popular, and we achieved high retention for follow-up data collection. Intervention community participants had 2.6 mmHg lower mean systolic BP and improved diet quality and BMI compared with control participants, although, as expected for a pilot study, the differences were not statistically significant. The culturally tailored diet intervention and randomized trial study design were acceptable and feasible for Chickasaw Nation adults with uncontrolled hypertension. Our findings support the value of tribal-food bank partnerships as a potential approach for reducing food insecurity and hypertension-related disparities in Native American communities.
