Process evaluation of the Yéego! Program to increase healthy eating and gardening among American Indian elementary school children.

BACKGROUND: American Indian children are at increased risk for obesity and diabetes. School-based health promotion interventions are one approach to promoting healthy behaviors to reduce this risk, yet few studies have described their implementation and fidelity. We conducted a qualitative process evaluation of the Yéego! Healthy Eating and Gardening Program, a school-based intervention to promote healthy eating among Navajo elementary school children. The intervention included a yearlong integrated curriculum, as well as the construction and maintenance of a school-based garden. METHODS: Our process evaluation included fidelity checklists completed by program staff and qualitative interviews with program staff and classroom teachers after the intervention was implemented. We used content analysis to identify themes. RESULTS: We identified several themes related to evidence of delivery adherence, program satisfaction, and lessons learned about delivery. Intervention staff followed similar procedures to prepare for and deliver lessons, but timing, teaching styles, and school-level factors also impacted overall implementation fidelity. Teachers and students had positive perceptions of the program, especially lessons that were highly visual, experiential, and connected to Navajo culture and the surrounding community. Teachers and program staff identified ways to enhance the usability of the curriculum by narrowing the scope, relating content to student experiences, and aligning content with school curriculum standards. CONCLUSIONS: The program was implemented with moderately high fidelity across contexts. We identified areas where modifications could improve engagement, acceptability, efficacy, and sustainability of the program. Our results have implications for the evaluation and dissemination of school-based health interventions to promote healthy eating among children, especially in American Indian communities.

An agricultural community's perspectives on COVID-19 testing to support safe school reopening.

Introduction: School-based COVID-19 testing may be an effective strategy for reducing transmission in schools and keeping schools open. The study objective was to examine community perspectives on school-based COVID-19 testing as a mitigation strategy to support safe school reopening. Methods: We conducted a qualitative study in Yakima County, an agricultural region of Washington state, where over half of residents are Hispanic/Latino. From June to July 2021, we interviewed 18 students (13 years old, on average) and 19 school employees, and conducted four focus groups (2 in Spanish, 2 in English) with 26 parents. We audio-recorded the semi-structured interviews and focus group discussions which were then transcribed. We used an inductive, constant comparison approach to code the transcripts and conducted a thematic analysis to generate themes. Results: We identified four main themes. Students, parents, and school employees desired a return to in-person learning (Theme 1). Schools implemented numerous COVID-19 mitigation strategies (e.g., masking) to facilitate a safe return to school but felt that adding testing would not be feasible due to a lack of resources and overworked staff (Theme 2). Parents and school employees' familiarity with COVID-19 testing procedures influenced their support for testing (Theme 3). Parents and school employees felt there were inadequate resources for individuals who test positive for COVID-19 (Theme 4). Discussion: Schools require adequate resources and medical personnel to implement COVID-19 testing. Individuals also need resources after testing positive, including physical space to isolate, financial resources for those without paid time off, and delivery of food and other necessities to households in rural communities.

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.

Engaging School and Family in Navajo Gardening for Health: Development of the Yéego Intervention to Promote Healthy Eating among Navajo Children.

OBJECTIVE: Navajo children are at increased risk for obesity, in part due to limited access to healthy foods. School garden interventions have been shown to increase access to fresh fruit and vegetables and consumption of healthy foods. Our study describes the development and pilot testing of a school garden intervention for Navajo elementary school children. METHODS: We reviewed existing school garden interventions and conducted formative research with students, caregivers, and school staff to inform the intervention. The intervention consisted of a garden built at the school and a yearlong curriculum on gardening and healthy eating. We pilot tested the intervention in an elementary school on the Navajo Nation. RESULTS: Formative research revealed the importance of incorporating Diné culture, including traditional growing practices and the preparation of traditional foods into the curriculum. School staff also stressed the value of tying the curriculum to state and Diné educational standards. Students enjoyed opportunities for hands-on activities and snack preparation. CONCLUSIONS: Schools have a meaningful role to play in addressing childhood obesity disparities among Navajo children. School-based interventions that draw on cultural strengths and include healthy traditional practices can be a promising strategy for increasing fruit and vegetable consumption.

Can Community Gardens with Workshops Increase Gardening Behavior? A Navajo Wellness Collaboration.

This project evaluated the potential efficacy of a community gardening intervention on the Navajo Nation to increase gardening and healthy eating behaviors, which are potentially important in preventing obesity and related health conditions. Rates of obesity are high among American Indians, including those living on Navajo Nation land. Eating fresh fruits and vegetables is part of healthy eating. However, availability and access to fresh fruits and vegetables are severely limited due to distance and cost. One way to increase both availability and consumption of fresh fruits and vegetables is through community gardening, yet many on the Navajo Nation have limited knowledge and capacity to garden. METHODS: We used a quasi-experimental pre-post study design to estimate the effect of a community gardening intervention. Primary outcomes of interest were gardening frequency and fruit and vegetable consumption. Community gardens were constructed and planted in two communities on the Navajo Nation. In addition, a series of gardening workshops were held in each community. Community members were recruited to complete surveys at time points before and after the workshops. The time between baseline and follow-up was approximately one year. RESULTS: We surveyed 169 participants at one time point at least, across both communities, and 25 of these participated in the gardening workshops. Within the 169, there was a cohort of 32 participants completing both baseline and follow-up surveys. For this cohort, interest in gardening increased from 78% to 97% (p=0.014), but none of the changes in gardening self-efficacy, knowledge or gardening frequency reached statistical significance. There were no measurable changes in reported fruit and vegetable consumption, self-efficacy or knowledge. Overall, the reported financial barriers to gardening increased from baseline to follow-up from 4.6 to 5.5 (p=0.035). Among those who completed follow-up, those who attended at least one workshop gardened more frequently than those who did not attend any workshops (21 times per month compared to 10 times per month (p=0.065). CONCLUSION: Despite enthusiasm for the community garden in both the communities studied and the increased interest in gardening, workshop attendance and participant retention in the study were low. These factors limited our ability to evaluate the potential efficacy of the intervention on gardening and healthy eating behaviors. Nonetheless, we found some evidence that participating in gardening workshops may lead to increased gardening frequency. Future studies should augment the intervention to include explicit efforts to reduce barriers to long term engagement and extend intervention reach.

Gardening for Health: Patterns of Gardening and Fruit and Vegetable Consumption Among the Navajo.

American Indians, including Navajo, are disproportionately affected by obesity and diabetes, in part due to diet-related health behaviors. The purpose of this study was to assess the patterns of gardening and fruit and vegetable (FV) consumption among residents in two communities on the Navajo Nation in order to inform a community gardening intervention. We analyzed survey data collected from participants in the Yéego Gardening study conducted in two communities in the Navajo Nation (N = 169). We found that 51% of the sample gardened, and on average participants gardened 8.9 times per month. Lack of time (53%) and financial barriers, such as gas for transportation or irrigation (51 and 49%, respectively), were reported as barriers to gardening. Most participants reported low levels of self-efficacy (80%) and behavioral capability (82%) related to gardening. Those with higher levels of gardening self-efficacy and behavioral capability reported more frequent gardening. Average daily FV consumption was 2.5 servings. Most participants reported high levels of self-efficacy to eat FV daily (64%) and high behavioral capability to prepare FV (66%). There was a positive association between FV consumption and gardening, with those gardening more than 4 times per month eating about 1 more serving of FV per day than those gardening 4 or fewer times per month. Further research is needed to better understand how gardening can increase fruit and vegetable availability and consumption among residents of the Navajo Nation.

Estimating the costs and cost-effectiveness of promoting mammography screening among US-based Latinas.

PURPOSE: We characterize the costs and cost-effectiveness of a community health worker (CHW)-based intervention to promote screening mammography among US-based non-adherent Latinas. METHODS: The parent study was a randomized controlled trial for 536 Latinas aged 42-74 years old who had sought care within a safety net health center in Western Washington. Participants were block-randomized within clinic to the control arm (usual care) or intervention arm (CHW-led motivational interviewing intervention). We used the perspective of the organization implementing promotional activities to characterize costs and cost-effectiveness. Cost data were categorized as program set-up and maintenance (initial training, booster/annual training) program implementation (administrative activities, intervention delivery); and, overhead/miscellaneous expenses. Cost-effectiveness was calculated as the incremental cost of screening for each additional woman screened between the intervention and control arms. RESULTS: The respective costs per participant for standard care and the intervention arm were $69.96 and $300.99. There were no study arm differences in 1-year QALYs were small among women who completed a 12-month follow-up survey (intervention= 0.8827, standard care = 0.8841). Most costs pertained to program implementation and administrative activities specifically. The incremental cost per additional woman screened was $2,595.32. CONCLUSIONS: Our findings are within the ranges of costs and cost-effectiveness for other CHW programs to promote screening mammography among underserved populations. Our strong study design and focus on non-adherent women provides important strengths to this body of work, especially give implementation and dissemination science efforts regarding CHW-based health promotion for health disparity populations.

Multi-level Intervention to increase participation in mammography screening: ¡Fortaleza Latina! study design.

BACKGROUND: Breast cancer is the most common cancer and the leading cause of death among Latinas in the United States. The Multi-level Intervention to Increase Participation in Mammography Screening study (¡Fortaleza Latina!) is a partnership among research institutions, a Latino-serving community-based primary care clinic organization, and a cancer treatment center. The study will assess the efficacy of a clinic- and patient-level program to increase breast cancer screening among Latinas in Western Washington. METHODS/DESIGN: The intervention is a multi-level breast cancer screening program in four participating primary care clinics. The study is a parallel randomized controlled trial of 600 Latino women aged 42-74 who are non-compliant with breast cancer screening guidelines. Participants will be randomized within clinic using block randomization to: (1) a control arm (usual care); and (2) a theory-based counseling program consisting of a 'promotora' or community health worker-led home-based intervention to encourage breast cancer screening. At the clinic-level, two clinics will offer additional mammography services provided by a mobile mammography unit operated by the Seattle Cancer Care Alliance. The primary endpoint is the rate of mammography uptake over the 1-year follow-up period. DISCUSSION: This multi-level intervention aims to raise rates of participation in breast cancer screening among Latino women. If effective, the program may improve rates of early detection of breast cancer in Latino women. Clinicaltrials.gov REGISTRATION NUMBER: NCT02010008.

Environmental assessment at worksites after a multilevel intervention to promote activity and changes in eating: the PACE project.

OBJECTIVE: To evaluate changes in the worksite environment in response to a multilevel intervention over a 2-year period. METHODS: Worksites were recruited in the greater Seattle area, and 34 were randomized to intervention or comparison condition. The intervention was based on the ecological model, with a framework of defined phases of intervention that included worksite-wide events implemented in partnership with employee-based advisory boards. The assessment of the worksite environment used a modification of the Checklist of Health Promotion Environments at Worksites. Subscales were developed using baseline data only. The intervention effect on different aspects of the worksite environment was estimated using logistic regression with robust estimating procedures. RESULTS: Only changes in the physical activity and nutrition information environments were significantly associated with the intervention. CONCLUSIONS: This article provides one of the first attempts at using environmental assessment in the evaluation of worksite interventions.
