Development of an Assessment Tool to Measure Healthy Eating in Navajo Children and Their Families.

Background: To estimate the efficacy of interventions to improve healthy eating, valid measures are essential. Although simple dietary intake tools have been developed with other populations, few have been culturally tailored and assessed for validity and reliability among Navajo. Objectives: This study aimed to develop a simple dietary intake tool tailored to Navajo culture, derive healthy eating indices, and assess their validity and reliability in Navajo children and adults and to describe the process used to develop this tool. Methods: A picture-sort tool using typically consumed foods was developed. Elementary school children and family members provided qualitative feedback in focus groups, used to refine the tool. Next, school-aged children and adults completed assessments at baseline and follow-up. Baseline behavior measures including child self-efficacy for fruits and vegetables (F&V) were examined for internal consistency. Healthy eating indices were derived from intake frequencies from picture sorting. The convergent validity of the indices and behavior measures for children and adults were examined. The reliability of the indices at the 2 time points was derived using Bland-Altman plots. Results: The picture-sort was refined from feedback provided by the focus groups. Baseline measures from 25 children and 18 adults were obtained. In children, a modified Alternative Healthy Eating Index (AHEI) and 2 other indices from the picture-sort were correlated with self-efficacy for eating F&V and had good reliability. In adults, the modified AHEI and 3 other indices from the picture-sort had significant correlations with adult abbreviated food frequency of F&V or obesogenic dietary index and had good reliability. Conclusions: The Navajo foods picture-sort tool developed for Navajo children and adults is proven to be acceptable and feasible to implement. Indices derived from the tool has good convergent validity and repeatability, supporting use in evaluating dietary change interventions in Navajo, with the potential for broader use of the approach in other underserved populations.

Diné (Navajo) Traditional Knowledge Holders' Perspective of COVID-19.

From the start of the COVID-19 pandemic on the Navajo Nation, Diné (Navajo) traditional knowledge holders (TKHs), such as medicine men and women and traditional practitioners, contributed their services and healing practices. Although TKHs are not always fully acknowledged in the western health care system, they have an established role to protect and promote the health of Diné people. To date, their roles in mitigating the COVID-19 pandemic have not been fully explored. The purpose of this research was to understand the social and cultural contexts of the COVID-19 pandemic and vaccines based on the roles and perspectives of Diné TKHs. A multi-investigator consensus analysis was conducted by six American Indian researchers using interviews with TKHs collected between December 2021-January 2022. The Hózhó Resilience Model was used as a framework to analyze the data using four parent themes: COVID-19, harmony and relationships, spirituality, and respect for self and discipline. These parent themes were further organized into promoters and/or barriers for 12 sub-themes that emerged from the data, such as traditional knowledge, Diné identity, and vaccine. Overall, the analysis showed key factors that could be applied in pandemic planning and public health mitigation efforts based on the cultural perspective of TKHs.

Utilizing Digital Storytelling to Develop a Public Health Professions Pathway for Native American High School Students.

Digital storytelling is a decentering methodology in health promotion that positions the storyteller as an expert to create a narrative of their lived experiences. This article describes using a two-phase digital storytelling process within the Diné (Navajo) Educational Philosophy framework to guide the development of a culturally grounded curriculum plan that actively engages Diné youth in exploring health professions pathways in their community. The first phase consisted of developing a high school digital storytelling team by training three Diné youth attending high school on the Navajo Nation located in southwest United States, in digital storytelling. In the second phase, the high school digital storytelling team worked collaboratively with seven Diné students enrolled at the local tribal college to develop digital stories about navigating from high school to college. Data from seven completed digital stories were analyzed with assistance from a community advisory board to identify asset-based themes that contributed to positively transitioning from high school to a tribal college. The results revealed several strategies for successful transitions from high school to a public health college major. The culturally relevant strategies and stories were incorporated into a school-based health professions pathway curriculum plan for Diné youth.

Engaging Native American High School Students in Public Health Career Preparation Through the Indigenous Summer Enhancement Program.

Native American populations are systematically marginalized in the healthcare and public health workforce. One effective approach to reduce health disparities and improve health care delivery among Indigenous populations is to train more Native American health professionals who integrate academic and cultural knowledge to understand and influence health behaviors and perspectives. Diné College partnered with Northern Arizona University to develop the Navajo Native American Research Center for Health (NARCH) Partnership, funded by the National Institutes of Health. The high school component of the Navajo NARCH Partnership created the Indigenous Summer Enhancement Program (ISEP), a 1-week summer training program providing exposure to health careers and mentorship in pursuing public health careers for Native American high school students. ISEP utilizes the Diné Educational Philosophy (DEP), a Navajo conceptual framework to serve as the foundation of the program. In 2020-2021, due to COVID-19 restrictions, the DEP model had to be incorporated in the Navajo NARCH high school virtual program activities. ISEP used 2018 and 2019 past program evaluation data to inform the virtual programming. Students' perception of the program was collected using an online Qualtrics evaluation questionnaire. Students stated appreciation for program staff, fellow students, peer mentors and culturally relevant learning experiences in both virtual and in-person environments. Recommendations included: expanding the length of ISEP and continuing the hands-on activities and Public Health Leadership series.

Group Randomized Trial of Healthy Eating and Gardening Intervention in Navajo Elementary Schools (Yéego!).

Introduction: Few healthy eating, school-based interventions have been rigorously evaluated in American Indian communities. Gardening and healthy eating are priorities in the Navajo Nation. Collaborations between researchers and local partners supported the design and implementation of this project. Design: The Yéego! Healthy Eating and Gardening Study was a group-randomized controlled trial to evaluate a school-based healthy eating and gardening intervention in 6 schools in the Navajo Nation. Schools were randomized 1:2 to intervention or comparison. Setting/participants: The Shiprock and Tsaile/Chinle areas in the Navajo Nation were selected. Elementary schools were screened for eligibility. All students in third and fourth grades were invited to participate in the assessments. Intervention: Delivered during 1 school year in the intervention schools, the intervention included a culturally relevant nutrition and gardening curriculum and a school garden. Main outcome measures: Student self-efficacy for eating fruits and vegetables, student self-efficacy for gardening, and student healthy foods score from a modified Alternative Healthy Eating Index were assessed in third and fourth graders at the beginning and end of a school year affected by the COVID-19 pandemic. Primary analyses used repeated measures linear mixed models accounting for students nested within schools to estimate the intervention effect and 95% CIs. Results: Students in the intervention schools had self-efficacy scores for eating fruits and vegetables that were 0.22 points greater (95% CI=0.04, 0.41) than those in the comparison schools, although the student healthy foods score increased in the intervention schools by 2.0 (95% CI=0.4, 3.6); the differential change was modest at 1.7 (95% CI=-0.3, 3.7). The self-efficacy to grow fruits and vegetables in the school garden increased among those in the intervention schools (OR=1.92; 95% CI=1.02, 3.63) but not significantly more than it increased in the comparison schools (OR=1.29; 95% CI=0.60, 2.81). Conclusions: The intervention was efficacious in improving self-efficacy for eating fruits and vegetables among third- and fourth-grade students over a school year. The findings warrant further evaluation of the intervention in larger-group randomized trials with schools in Navajo communities. Trial registration: This study is registered at clinicaltrials.gov NCT03778021.

Adapting Summer Education Programs for Navajo Students: Resilient Teamwork.

In May 2020, the Navajo Native American Research Center for Health Partnership (Navajo NARCH) was scheduled to launch two summer programs: a 10 weeks-long Summer Research Enhancement Program (SREP) for undergraduate students to learn and practice health research methods and participate in a practicum experience, and a week-long Indigenous Summer Enhancement Program (ISEP) for high school students that introduces a range of health professions and develops leadership qualities. Students accepted into the programs are predominantly Navajo and live within Navajo Nation (NN) during the summer. Due to NN restrictions and CDC guidelines for physically distancing in response to the coronavirus (COVID-19) pandemic, the Navajo NARCH team organized to offer both programs entirely online via Zoom™. This paper explores the instructional teams' adaptation process to maintain a commitment to preserve the programs' supportive environment for exploring and developing strong multicultural approaches in public health and health research. In preparation for online instruction, the team developed and offered workshops for staff and instructors to address anticipated challenges. The team identified the following challenges: technological difficulties, social disconnectedness, consistent student engagement, and facilitation of a practicum research experience. Results showed that program adaptations were successful as the team applied collaborative and holistic approaches, and established social connections remotely with students to offer meaningful research and practicum experiences.

Development and Evaluation of a Cancer Literacy Intervention to Promote Mammography Screening Among Navajo Women: A Pilot Study.

PURPOSE: Develop and evaluate a mammography intervention that provides hope about cancer prevention and treatment. DESIGN: Pilot randomized controlled trial. SETTING: Two communities on the Navajo Nation. PARTICIPANTS: Navajo women and support persons. INTERVENTION: Both groups received standard care: one home visit discussing mammography pros/cons and barriers. The treatment group received an intervention based on Navajo language via an additional home visit with health education materials (written and oral) in English and Navajo, including a Navajo Cancer Glossary with a new descriptive phrase for cancer. ANALYSIS: Between control and intervention conditions, we compared baseline sociodemographics; changes from baseline to 3 months on mammography completion and breast cancer literacy scores. MEASURES: (1) intervention feasibility; (2) self- and clinic-reported mammography screening completion; (3) breast cancer literacy. RESULTS: A total of 25 participants were randomly assigned (13 treatment, 12 control), with 7 support persons in each arm. Mean age was 53 years, 90% had a high school degree or higher, 86% spoke Navajo and English. At 3 months, 44% had a clinically verified mammogram. Mammography completion was 57% among those with a support person and 27% among those without (P = .14). Intervention women reported more breast cancer beliefs consistent with mammography (P = .015). CONCLUSIONS: Increases in breast cancer beliefs consistent with mammography show promise. Findings highlight a need to tailor education materials to Navajo culture/language and focus on enhancing support.

Adapting a Cancer Literacy Measure for Use Among Navajo Women.

PURPOSE: The authors designed a community-based participatory research study to develop and test a family-based behavioral intervention to improve cancer literacy and promote mammography among Navajo women. METHOD: Using data from focus groups and discussions with a community advisory committee, they adapted an existing questionnaire to assess cancer knowledge, barriers to mammography, and cancer beliefs for use among Navajo women. Questions measuring health literacy, numeracy, self-efficacy, cancer communication, and family support were also adapted. RESULTS: The resulting questionnaire was found to have good content validity, and to be culturally and linguistically appropriate for use among Navajo women. CONCLUSIONS: It is important to consider culture and not just language when adapting existing measures for use with AI/AN (American Indian/Alaskan Native) populations. English-language versions of existing literacy measures may not be culturally appropriate for AI/AN populations, which could lead to a lack of semantic, technical, idiomatic, and conceptual equivalence, resulting in misinterpretation of study outcomes.

Development and pilot evaluation of Native CREST-a Cancer Research Experience and Student Training program for Navajo undergraduate students.

The Mayo Clinic Cancer Center and Diné College received funding for a 4-year collaborative P20 planning grant from the National Cancer Institute in 2006. The goal of the partnership was to increase Navajo undergraduates' interest in and commitment to biomedical coursework and careers, especially in cancer research. This paper describes the development, pilot testing, and evaluation of Native CREST (Cancer Research Experience and Student Training), a 10-week cancer research training program providing mentorship in a Mayo Clinic basic science or behavioral cancer research lab for Navajo undergraduate students. Seven Native American undergraduate students (five females, two males) were enrolled during the summers of 2008-2011. Students reported the program influenced their career goals and was valuable to their education and development. These efforts may increase the number of Native American career scientists developing and implementing cancer research, which will ultimately benefit the health of Native American people.

Development and pilot evaluation of a cancer-focused summer research education program for [corrected] Navajo undergraduate students.

This paper describes the development and pilot testing of a 10-week cancer research education program for Navajo undergraduate students. The program was piloted at Diné College with 22 undergraduates (7 men, 15 women) in 2007 and 2008. Students completed a pre-post program survey assessing attitudes, opinions, and knowledge about research and about cancer. The program was found to be culturally acceptable and resulted in statistically significant changes in some of the attitudes and opinions about research and cancer. Combining all 13 knowledge items, there was a significant (p = 0.002) change in the mean total correct percent from baseline [70.3 (SD = 15.9)] to post-program [82.1 (SD = 13.1)]. The curriculum was adapted for a new cancer prevention and control course now offered at Diné College, enhancing sustainability. Ultimately, these efforts may serve to build capacity in communities by developing a cadre of future Native American scientists to develop and implement cancer research.
