Assessment of Interest in a Virtual Avatar-Based Nutrition Education Program Among Youth-Serving Community Partners.

OBJECTIVE: Examine the appeal of a virtual avatar-led nutrition education program among youth-serving community partners in North Carolina. METHODS: We surveyed community partners using the Diffusion of Innovation Theory constructs of relative advantage, compatibility, and complexity. Logistic regression evaluated the appeal and likelihood of the program's future use. RESULTS: Community partners (n = 100) agreed that the program was an innovative (87%) and convenient (85%) way for youth and parents to learn about nutrition. Partners who perceived the program as a relative advantage to current programs had significantly higher odds of future use intention (P = 0.005). Those who found it compatible with organizational and personal values had significantly higher odds of future use (P < 0.001). CONCLUSIONS AND IMPLICATIONS: A nutrition education virtual avatar program is of interest to youth-engaged community partners. Future research examining the potential integration of this type of program within community organizations is warranted.

Multi-Method Formative Evaluation of a Digital Online Grocery Shopping Assistant Among Special Supplemental Nutrition Program for Women, Infants, and Children Participants.

OBJECTIVE: Assess the acceptability of a digital grocery shopping assistant among rural women with low income. DESIGN: Simulated shopping experience, semistructured interviews, and a choice experiment. SETTING: Rural central North Carolina Special Supplemental Nutrition Program for Women, Infants, and Children clinic. PARTICIPANTS: Thirty adults (aged ≥18 years) recruited from a Special Supplemental Nutrition Program for Women, Infants, and Children clinic. PHENOMENON OF INTEREST: A simulated grocery shopping experience with the Retail Online Shopping Assistant (ROSA) and mixed-methods feedback on the experience. ANALYSIS: Deductive and inductive qualitative content analysis to independently code and identify themes and patterns among interview responses and quantitative analysis of simulated shopping experience and choice experiment. RESULTS: Most participants liked ROSA (28/30, 93%) and found it helpful and likely to change their purchase across various food categories and at checkout. Retail Online Shopping Assistant's reminders and suggestions could reduce less healthy shopping habits and diversify food options. Participants desired dynamic suggestions and help with various health conditions. Participants preferred a racially inclusive, approachable, cartoon-like, and clinically dressed character. CONCLUSIONS AND IMPLICATIONS: This formative study suggests ROSA could be a beneficial tool for facilitating healthy online grocery shopping among rural shoppers. Future research should investigate the impact of ROSA on dietary behaviors further.

Associations between food and beverage purchases and skin carotenoids among diverse small food retail store customers.

OBJECTIVE: To determine if customer purchases at small food stores are associated with healthfulness of the diet as approximated by skin carotenoids. DESIGN: This is a cross-sectional survey of customers in small food stores regarding demographics and food purchases. Food and beverage purchases were classified as 'healthy' or 'non-healthy' and 'carotenoid' v. 'non-carotenoid' using a systematic classification scheme. Fruit and vegetable intake was objectively assessed using a non-invasive device to measure skin carotenoids. Associations between variables of interest were examined using Pearson's correlation coefficients, t tests and multiple linear regression analyses. SETTING: Twenty-two small food retail stores in rural (n 7 stores) and urban (n 15) areas of North Carolina. PARTICIPANTS: Customers of small food stores. RESULTS: Of study participants (n 1086), 55·1 % were male, 60·0 % were African American/Black and 4·2 % were Hispanic, with a mean age of 43·5 years. Overall, 36 % purchased at least one healthy item, and 7·6 % of participants purchased a carotenoid-containing food/beverage. Healthy foods and beverages purchased included produce, lean meats, 100 % juices, plain popcorn, plain nuts, milk and yogurt. Unhealthy items included non-100 % juices, crackers, chips, candy, cakes and donuts. Purchase of a healthy or carotenoid-containing item was positively associated with skin carotenoid scores (P = 0·002 and 0·006, respectively). CONCLUSIONS: A relatively small proportion of customers purchased any healthy or carotenoid-containing foods and beverages, and those who did purchase healthy options had higher skin carotenoid scores. Future research should confirm these findings in different populations.

Bidirectional Relations Between Daily Stress and Sleep Among Black Emerging Adults.

BACKGROUND: Black adults experience higher levels of stress and more dysfunctional sleep patterns compared to their White peers, both of which may contribute to racial disparities in chronic health conditions. Dysfunctional sleep patterns are also more likely in emerging adults compared to other age groups. Daily stress-sleep relations in Black emerging adults are understudied. PURPOSE: This study used ecological momentary assessment (EMA) and wrist-worn actigraphy to examine bidirectional associations between daily stress and sleep among Black emerging adults. METHODS: Black college freshmen (N = 50) completed an EMA protocol (i.e., five EMA prompts/day) and wore an accelerometer for 7 days. The first EMA prompt of each day assessed sleep duration and quality. All EMA prompts assessed stress. Wrist-worn actigraphy assessed nocturnal sleep duration, sleep onset latency, sleep efficiency, and waking after sleep onset. RESULTS: At the within-person level, stress experienced on a given day was not associated with any sleep metrics that night (p > .05). On evenings when actigraphy-based sleep duration was shorter (B = -0.02, p = .01) and self-reported sleep quality was poorer (B = -0.12, p = .02) than usual, stress was greater the following day. At the between-person level, negative bidirectional relations existed between stress and actigraphy-based waking after sleep onset (stress predicting sleep: B = -0.35, p = .02; sleep predicting stress: B = -0.27, p = .04). CONCLUSIONS: Among Black emerging adults, associations between daily sleep and stress vary at the between- and within-person level and are dependent upon the sleep metric assessed. Future research should compare these relations across different measures of stress and different racial/ethnic groups to better understand health disparities.

Geospatial Reach of the Maryland COVID-19 School Meals Response: Spring 2020.

OBJECTIVE: Examine characteristics of pandemic meal site (n = 602) location and meals served per site in Maryland, Spring 2020, following federal/state waivers for local meal site placement decision-making. METHODS: Using geographic information systems, we connected meal sites to census tract-level data and generated service areas from sites and distances from population-weighted census tract centroids to the closest pandemic meal site. Regression analysis determined associations of census tract pandemic meal site count and meals served per site with socioeconomic and demographic variables. RESULTS: Census tracts with more meal sites were urban (P < 0.001), food deserts (P < 0.001), and had higher percentages of children in poverty (P < 0.001). Sites serving fewer meals were in food deserts (P < 0.001) and areas with more children in poverty (P < 0.001). CONCLUSIONS AND IMPLICATIONS: Waivers allowing local meal site placement decision-making supported meal sites in high-need areas. Geospatial approaches could optimize site locations to ensure maximum reach to populations in need. Additional supports may be needed to ensure children in poverty areas receive meals distributed at these sites.

Evidence of Geospatial and Socioeconomic Disparities in Access to Online Grocery Shopping for Fresh and Frozen Produce in North Carolina.

BACKGROUND: Online grocery shopping is a rapidly growing food procurement approach in the United States with the potential to improve food access. Limited research has focused on understanding differential access to online grocery shopping that provides healthier items such as fresh or frozen fruits and vegetables. OBJECTIVE: The study aim was to understand geospatial, socioeconomic, and racial disparities in the availability of healthy online grocery shopping and online Supplemental Nutrition Assistance Program (SNAP) acceptance in North Carolina. DESIGN: A cross-sectional study was conducted during spring 2021. PARTICIPANTS/SETTING: A listing of grocery stores with online shopping was generated using a systematic search strategy. Stores were geocoded and spatially joined to relevant contextual (rural/urban [based on US Department of Agriculture Rural Urban Continuum codes]), broadband Internet availability, socioeconomic variables (ie, percent poverty and Social Vulnerability Index), and demographic variables (ie, percent racial minority) in geographic information systems software. MAIN OUTCOME MEASURES: Prevalence rate ratios (PRRs) of healthy online grocery shopping (availability of curbside pickup or home delivery of fresh and frozen produce), and online SNAP acceptance (ie, availability of online SNAP), at the census tract level (n = 2,162). STATISTICAL ANALYSES PERFORMED: PRRs for availability of healthy online grocery shopping and SNAP online acceptance at the census tract level (n = 2,162) were modeled using Poisson regression with robust standard errors. RESULTS: This study found disparities in access to healthy online grocery shopping and SNAP online shopping availability in North Carolina. Healthy online shopping availability rates were higher in urban census tracts (PRR 1.68, 95% CI 1.47 to 1.92), areas with lower Social Vulnerability Index scores (PRR 0.99, 95% CI 0.98 to 0.99), higher Internet Availability Index scores (PRR 1.21, 95% CI 1.17 to 1.25), and lower percent poverty (PRR 0.94, 95% CI 0.90 to 0.98). SNAP online shopping availability rates were higher in urban census tracts (PRR 1.41, 95% CI 1.16 to 1.65), areas with higher Social Vulnerability Index scores (PRR 1.02, 95% CI 1.01 to 1.04), higher Internet Availability Index scores (PRR 1.15, 95% CI 1.10 to 1.20), and higher percent minority (PRR 1.02, 95% CI 1.0001 to 1.03). SNAP online shopping availability rates were lower in areas with higher percent poverty (PRR 0.90, 95% CI 0.85 to 0.95). CONCLUSIONS: This study found disparities in access to healthy online grocery shopping and SNAP online shopping for rural areas, and areas with higher poverty, and lower broadband Internet access in North Carolina. Further research is needed to identify effective strategies for addressing these disparities.

EatWellNow: Formative Development of a Place-Based Behavioral "Nudge" Technology Intervention to Promote Healthier Food Purchases among Army Soldiers.

Approximately 17% of military service members are obese. Research involving army soldiers suggests a lack of awareness of healthy foods on post. Innovative approaches are needed to change interactions with the military food environment. Two complementary technological methods to raise awareness are geofencing (deliver banner ads with website links) and Bluetooth beacons (real-time geotargeted messages to mobile phones that enter a designated space). There is little published literature regarding the feasibility of this approach to promote healthy behaviors in retail food environments. Thus, we conducted a formative feasibility study of a military post to understand the development, interest in, and implementation of EatWellNow, a multi-layered interactive food environment approach using contextual messaging to improve food purchasing decisions within the military food environment. We measured success based on outcomes of a formative evaluation, including process, resources, management, and scientific assessment. We also report data on interest in the approach from a Fort Bragg community health assessment survey (n = 3281). Most respondents agreed that they were interested in receiving push notifications on their phone about healthy options on post (64.5%) and that receiving these messages would help them eat healthier (68.3%). EatWellNow was successfully developed through cross-sector collaboration and was well received in this military environment, suggesting feasibility in this setting. Future work should examine the impact of EatWellNow on military service food purchases and dietary behaviors.

Perceived barriers and facilitators to participating in the North Carolina Healthy Food Small Retailer Program: a mixed-methods examination considering investment effectiveness.

OBJECTIVE: The North Carolina Legislature appropriated funds in 2016-2019 for the Healthy Food Small Retailer Program (HFSRP), providing small retailers located in food deserts with equipment to stock nutrient-dense foods and beverages. The study aimed to: (1) examine factors facilitating and constraining implementation of, and participation in, the HFSRP from the perspective of storeowners and (2) measure and evaluate the impact and effectiveness of investment in the HFSRP. DESIGN: The current analysis uses both qualitative and quantitative assessments of storeowner perceptions and store outcomes, as well as two innovative measures of policy investment effectiveness. Qualitative semi-structured interviews and descriptive quantitative approaches, including monthly financial reports and activity forms, and end-of-programme evaluations were collected from participating HFSRP storeowners. SETTING: Eight corner stores in North Carolina that participated in the two cohorts (2016-2018; 2017-2019) of the HFSRP. PARTICIPANTS: Owners of corner stores participating in the HFSRP. RESULTS: All storeowners reported that the HFSRP benefitted their stores. In addition, the HFSRP had a positive impact on sales across each category of healthy food products. Storeowners reported that benefits would be enhanced with adjustments to programme administration and support. Specific suggestions included additional information regarding which healthy foods and beverages to stock; inventory management; handling of perishable produce; product display; modified reporting requirements and a more efficient process of delivering and maintaining equipment. CONCLUSIONS: All storeowners reported several benefits of the HFSRP and would recommend that other storeowners participate. The barriers and challenges they reported inform potential approaches to ensuring success and sustainability of the HFSRP and similar initiatives underway in other jurisdictions.

Qualitative perspectives of the North Carolina healthy food small retailer program among customers in participating stores located in food deserts.

BACKGROUND: The North Carolina Healthy Food Small Retailer Program (NC HFSRP) was established through a policy passed by the state legislature to provide funding for small food retailers located in food deserts with the goal of increasing access to and sales of healthy foods and beverages among local residents. The purpose of this study was to qualitatively examine perceptions of the NC HFSRP among store customers. METHODS: Qualitative interviews were conducted with 29 customers from five NC HFSRP stores in food deserts across eastern NC. Interview questions were related to shoppers' food and beverage purchases at NC HFSRP stores, whether they had noticed any in-store efforts to promote healthier foods and beverages, their suggestions for promoting healthier foods and beverages, their familiarity with and support of the NC HFSRP, and how their shopping and consumption habits had changed since implementation of the NC HFSRP. A codebook was developed based on deductive (from the interview guide questions) and inductive (emerged from the data) codes and operational definitions. Verbatim transcripts were double-coded and a thematic analysis was conducted based on code frequency, and depth of participant responses for each code. RESULTS: Although very few participants were aware of the NC HFSRP legislation, they recognized changes within the store. Customers noted that the provision of healthier foods and beverages in the store had encouraged them to make healthier purchase and consumption choices. When a description of the NC HFSRP was provided to them, all participants were supportive of the state-funded program. Participants discussed program benefits including improving food access in low-income and/or rural areas and making healthy choices easier for youth and for those most at risk of diet-related chronic diseases. CONCLUSIONS: Findings can inform future healthy corner store initiatives in terms of framing a rationale for funding or policies by focusing on increased food access among vulnerable populations.

USDA Special Supplemental Nutrition Program for Women, Infants and Children (WIC) Vendor Criteria: An Examination of US Administrative Agency Variations.

The food retail environment has been directly linked to disparities in dietary behaviors and may in part explain racial and ethnic disparities in pregnancy-related deaths. The Special Supplemental Nutrition Program for Women, Infants and Children (WIC), administered by the United States Department of Agriculture, is associated with improved healthy food and beverage access due to its requirement for minimum stock of healthy foods and beverages in WIC-eligible stores. The selection and authorization criteria used to authorize WIC vendors varies widely from state to state with little known about the specific variations. This paper reviews and summarizes the differences across 16 of these criteria enacted by 89 WIC administrative agencies: the 50 states, the District of Columbia, five US Territories, and 33 Indian Tribal Organizations. Vendor selection and authorization criteria varied across WIC agencies without any consistent pattern. The wide variations in criteria and policies raise questions about the rational for inconsistency. Some of these variations, in combination, may result in reduced access to WIC-approved foods and beverages by WIC participants. For example, minimum square footage and/or number of cash register criteria may limit vendors to larger retail operations that are not typically located in high-risk, under-resourced communities where WIC vendors are most needed. Results highlight an opportunity to convene WIC stakeholders to review variations, their rationale, and implications thereof especially as this process could result in improved policies to ensure and improve healthy food and beverage access by WIC participants. More work remains to better understand the value of state WIC vendor authorization authority, particularly in states that have provided stronger monitoring requirements. This work might also examine if and how streamlining WIC vendor criteria (or at least certain components of them) across regional areas or across the country could provide an opportunity to advance interstate commerce and promote an equitable supply of food across the food system, while ensuring the protection for local, community-oriented WIC vendors.

A four-year observational study to examine the dietary impact of the North Carolina Healthy Food Small Retailer Program, 2017-2020.

BACKGROUND: The North Carolina (NC) Healthy Food Small Retailer Program (HFSRP) was passed into law with a $250,000 appropriation (2016-2018) providing up to $25,000 in funding to small food stores for equipment to stock healthier foods and beverages. This paper describes an observational natural experiment documenting the impact of the HFSRP on store food environments, customers' purchases and diets. METHODS: Using store observations and intercept surveys from cross-sectional, convenience customer samples (1261 customers in 22 stores, 2017-2020; 499 customers in 7 HFSRP stores, and 762 customers in 15 Comparison stores), we examined differences between HFSRP and comparison stores regarding: (1) change in store-level availability, quality, and price of healthy foods/beverages; (2) change in healthfulness of observed food and beverage purchases ("bag checks"); and, (3) change in self-reported and objectively-measured (Veggie Meter®-assessed skin carotenoids) customer dietary behaviors. Differences (HFSRP vs. comparison stores) in store-level Healthy Food Supply (HFS) and Healthy Eating Index-2010 scores were assessed using repeated measure ANOVA. Intervention effects on diet were assessed using difference-in-difference models including propensity scores. RESULTS: There were improvements in store-level supply of healthier foods/beverages within 1 year of program implementation (0 vs. 1-12 month HFS scores; p = 0.055) among HFSRP stores only. Comparing 2019 to 2017 (baseline), HFSRP stores' HFS increased, but decreased in comparison stores (p = 0.031). Findings indicated a borderline significant effect of the intervention on self-reported fruit and vegetable intake (servings/day), though in the opposite direction expected, such that fruit and vegetable intake increased more among comparison store than HFSRP store customers (p = 0.05). There was no significant change in Veggie Meter®-assessed fruit and vegetable intake by customers shopping at the intervention versus comparison stores. CONCLUSIONS: Despite improvement in healthy food availability, there was a lack of apparent impact on dietary behaviors related to the HFSRP, which could be due to intervention dose or inadequate statistical power due to the serial cross-sectional study design. It may also be that individuals buy most of their food at larger stores; thus, small store interventions may have limited impact on overall eating patterns. Future healthy retail policies should consider how to increase intervention dose to include more product marketing, consumer messaging, and technical assistance for store owners.

Virtual Avatar Coaching With Community Context for Adult-Child Dyads with Low Income.

OBJECTIVE: Examine the acceptability of an evidence-based, contextually tailored, virtual avatar coaching approach for nutrition education among adult-child dyads with low income. DESIGN: Structured observations and semistructured interviews. SETTING: Low-income communities in 2 midsized urban areas. PARTICIPANTS: Fifteen African American adult and child (aged 5-10 years old) dyads recruited from community agencies. PHENOMENON OF INTEREST: Structured observation during the use of the virtual avatar coaching program and qualitative feedback on program experience after using the program. ANALYSIS: Transcripts were independently coded by 2 trained coders. Content analysis was conducted to determine trends and patterns in responses, and salient quotes were extracted from the manuscripts. RESULTS: The program generated dialogue between the children and adults around preferences and dietary habits. Adults and children described the program as being helpful, informative, motivational, and fun. Adults and children liked that the avatar acknowledged them at a personal level, provided accountability, and was tailored to them and their environment. Children wanted the ability to customize the avatar, more gamification, and avatar demonstration of healthy behaviors. Children felt the program would improve their health behaviors and were interested in using it again. CONCLUSIONS AND IMPLICATIONS: This study highlights information that can be used to improve avatar-based programs for nutrition education with children and their adult caregivers who have low income. Future work should assess the impact of user customization experience, program impact on dietary behaviors, and resources required to scale and maintain the program with community agencies.

Nondiet Weight-Neutral Curricula Limited in Current Accredited US Dietetic Programs.

OBJECTIVE: Determine awareness and prevalence of, and interest in nondiet weight-neutral (NDWN) focused curriculum and factors associated with the presence in accredited dietetic programs throughout the US. METHODS: Online cross-sectional survey sent to directors of US Coordinated Programs (n = 60) and Didactic Programs in Dietetics (n = 214). RESULTS: 116 programs (42%) responded, 95% reported knowledge of NDWN approaches to weight management like Health at Every Size. Most schools (72%) included NDWN in their curriculum, mostly in a single lecture (53%). Most respondents (74%) reported interest in an NDWN curriculum. Common factors for not including NDWN were: lack of trained and knowledgeable staff (35%) and insufficient space in the curriculum to incorporate additional topics (35%). CONCLUSIONS AND IMPLICATIONS: Most knew of NDWN approaches and included in curricula but only as 1 lecture. Faculty training and curriculum flexibility may help support the increased incorporation of NDWN approaches.

Associations between shopping patterns, dietary behaviours and geographic information system-assessed store accessibility among small food store customers.

OBJECTIVE: To examine associations between geographic information systems (GIS)-assessed accessibility to small food stores, shopping patterns and dietary behaviours among small food store customers. DESIGN: Residential addresses and customer shopping patterns (frequency of shopping, and previous purchase of fruits and vegetables) were gathered through customer intercept surveys. Addresses were geocoded, and GIS-assessed distance and driving time from the participants' residence to the store were calculated. Dietary status and behaviours were assessed using an objective non-invasive measure of skin carotenoids, the National Cancer Institute Fruit and Vegetable Screener, and items to assess sugary beverage intake. Associations between distance and driving time, demographics, shopping frequency, prior reported purchase of fruits and vegetables at the store and dietary behaviours were examined. SETTING: Small food stores (n 22) across North Carolina. PARTICIPANTS: Cross-sectional convenience samples of English-speaking customers aged 18 years or older (n 692). RESULTS: Participants living closer to the small store had lower income and formal education, were more likely to be Black, more likely to have previously bought fruits and vegetables at the store and more frequently shopped at the store. In adjusted models, skin carotenoids (n 644) were positively associated with distance to the store from home in miles (P = 0·01). CONCLUSIONS: Customers who lived closer to the stores were more frequent shoppers and more likely to have previously purchased fruits and vegetables at the store yet had lower skin carotenoids. These results support continued efforts to examine how to increase the availability and promotion of healthful foods at small food retail stores.

Influence of Nutrient Intake on 24 Hour Urinary Hydration Biomarkers Using a Clustering-Based Approach.

Previous work focusing on understanding nutrient intake and its association with total body water homeostasis neglects to consider the collinearity of types of nutrients consumed and subsequent associations with hydration biomarkers. Therefore, the purpose of this study was to analyze consumption patterns of 23 a priori selected nutrients involved in osmotic homeostasis, as well as their association with 24 h urinary hydration markers among fifty African-American first-year college students through a repeated measures observation in a daily living setting. Through application of hierarchical clustering, we were able to identity four clusters of nutrients based on 24 h dietary recalls: (1) alcohol + pinitol, (2) water + calcium + magnesium + erythritol + inositol + sorbitol + xylitol, (3) total calories + total fat + total protein + potassium + sodium + zinc + phosphorous + arginine, and (4) total carbohydrates + total fiber + soluble fiber + insoluble fiber + mannitol + betaine. Furthermore, we found that consumption of nutrients in Cluster #2 was significantly predictive of urine osmolality (p = 0.004); no other clusters showed statistically significant associations with 24 h urinary hydration biomarkers. We conclude that there may be some nutrients that are commonly consumed concomitantly (at the day level), across a variety of settings and populations, and that a limited subset of the clustering of these nutrients may associate with body water status.

Addressing Food Insecurity through a Health Equity Lens: a Case Study of Large Urban School Districts during the COVID-19 Pandemic.

Reduced access to school meals during public health emergencies can accelerate food insecurity and nutritional status, particularly for low-income children in urban areas. To prevent the exacerbation of health disparities, there is a need to understand the implementation of meal distribution among large urban school districts during emergencies and to what degree these strategies provide equitable meal access. Our case study of four large urban school districts during the COVID-19 pandemic aims to address these knowledge gaps. Guided by the Getting to Equity (GTE) framework, we conducted a mixed-methods study evaluating emergency meal distribution and strategy implementation in four large urban school districts (Chicago Public Schools, Houston Independent School District, Los Angeles Unified School District, and New York City Department of Education). We gathered data from school district websites on (1) meal service and delivery sites and (2) district documents, policies, communication, and resources. Using qualitative coding approaches, we identified unique and shared district strategies to address meal distribution and communications during the pandemic according to the four components of the GTE framework: increase healthy options, reduce deterrents, build on community capacity, and increase social and economic resources. We matched district census tract boundaries to demographic data from the 2018 American Community Survey and United States Department of Agriculture food desert data, and used geographic information systems (GIS) software to identify meal site locations relative to student population, areas of high poverty and high minority populations, and food deserts. We found that all districts developed strategies to optimize meal provision, which varied across case site. Strategies to increase healthy options included serving adults and other members of the general public, providing timely information on meal site locations, and promoting consumption of a balanced diet. The quantity and frequency of meals served varied, and the degree to which districts promoted high-quality nutrition was limited. Reducing deterrents related to using inclusive language and images and providing safety information on social distancing practices in multiple languages. Districts built community capacity through partnering with first responder, relief, and other community organizations. Increased social and economic resources were illustrated by providing technology assistance to families, childcare referrals for essential workers, and other wellness resources. Geospatial analysis suggests that service locations across cities varied to some degree by demographics and food environment, with potential gaps in reach. This study identifies strategies that have the potential to increase equitable access to nutrition assistance programs. Our findings can support (1) ongoing efforts to address child food insecurity during the pandemic and (2) future meal provision through programs like the Summer Food Service Program and Seamless Summer Option. Future research should further examine the rationale behind meal site placement and how site availability changed over time.

Extended Reality Technologies in Nutrition Education and Behavior: Comprehensive Scoping Review and Future Directions.

The use of Extended Reality (XR) (i.e. Virtual and Augmented Reality) for nutrition education and behavior change has not been comprehensively reviewed. This paper presents findings from a scoping review of current published research. Articles (n = 92) were extracted from PubMed and Scopus using a structured search strategy and selection approach. Pertinent study information was extracted using a standardized data collection form. Each article was independently reviewed and coded by two members of the research team, who then met to resolve any coding discrepancies. There is an increasing trend in publication in this area, mostly regarding Virtual Reality. Most studies used developmental testing in a lab setting, employed descriptive or observational methods, and focused on momentary behavior change like food selection rather than education. The growth and diversity of XR studies suggest the potential of this approach. There is a need and opportunity for more XR technology focused on children and other foundational theoretical determinants of behavior change to be addressed within nutrition education. Our findings suggest that XR technology is a burgeoning approach in the field of nutrition, but important gaps remain, including inadequate methodological rigor, community application, and assessment of the impact on dietary behaviors.

Momentary Physical Activity Co-Occurs with Healthy and Unhealthy Dietary Intake in African American College Freshmen.

Background: Research investigating interrelations between physical activity and dietary intake has primarily used retrospective, summary-based measures of behavior subject to increased recall bias. This study used ecological momentary assessment (EMA) methods with accelerometry to determine within-day, momentary associations between physical activity and dietary intake behaviors in African American college freshmen. Methods: Participants (N = 50) completed a dietary EMA protocol that assessed food/fluids consumed over the past 2 h at five random times per day and wore an activPAL accelerometer for 7 days to measure physical activity. Physical activity was operationalized as step counts in the 2 h prior to the EMA prompt (matching the EMA recall window). Results: On occasions when participants took more steps than was typical for them in the 2 h prior to the EMA prompt, they were more likely to consume sugar-sweetened beverages (OR = 1.37, p < 0.001), water (OR = 1.28, p < 0.001), fruit (OR = 1.44, p < 0.001), vegetables (OR = 1.19, p = 0.02), and fried fast food (OR = 1.21, p = 0.04) over that same time. Conclusion: Momentary physical activity co-occurred with momentary consumption of both healthy and unhealthy dietary intake. These behavioral interrelations suggest potential implications for obesity risk and multiple health behavior change interventions in young adult African Americans.

Racial and Sex Differences in 24 Hour Urinary Hydration Markers among Male and Female Emerging Adults: A Pilot Study.

The purpose of this study was to examine 24 h urinary hydration markers in non-Hispanic White (WH) and non-Hispanic Black (BL) males and females. Thirteen males (BL, n = 6; WH, n = 7) and nineteen females (BL, n = 16, WH, n = 3) (mean ± SD; age, 20 ± 4 y; height, 169.2 ± 12.2 cm; body mass, 71.3 ± 12.2 kg; body fat, 20.8 ± 9.7%) provided a 24 h urine sample across 7 (n = 13) or 3 (n = 19) consecutive days (148 d total) for assessment of urine volume (UVOL), urine osmolality (UOSM), urine specific gravity (USG), and urine color (UCOL). UVOL was significantly lower in BL (0.85 ± 0.43 L) compared to WH college students (2.03 ± 0.70 L) (p < 0.001). Measures of UOSM, USG, and UCOL, were significantly greater in BL (716 ± 263 mOsm∙kg-1, 1.020 ± 0.007, and 4.2 ± 1.4, respectively) compared to WH college students (473 ± 194 mOsm∙kg-1, 1.013 ± 0.006, 3.0 ± 1.2, and respectively) (p < 0.05). Differences in 24 h urinary hydration measures were not significantly different between males and females (p > 0.05) or between the interaction of sex and race/ethnicity (p > 0.05). Non-Hispanic Black men and women were inadequately hydrated compared to their non-Hispanic White counterparts. Our findings suggest that development of targeted strategies to improve habitual fluid intake and potentially overall health are needed.

Food and Beverage Options at Highway Rest Areas in North Carolina: A Mixed-Methods Audit and Geospatial Approach.

INTRODUCTION: Each year, millions of people purchase food at highway rest areas. Rest areas are potential sites for health promotion because they are operated by the public sector; they are frequently visited by professional truck drivers, who have a disproportionate burden of chronic disease; and they are easily accessible. To our knowledge, no research has systematically examined the healthfulness of food offerings at rest areas. The objective of this study was to determine the accessibility and healthfulness of food and beverages offered at highway rest areas in North Carolina using a mixed-methods audit and geospatial approach. METHODS: We conducted a cross-sectional audit of all rest areas offering foods and beverages in North Carolina (N = 30) in summer 2018. We used the Nutrition Environment Measures Survey-Vending (NEMS-V) to record the 1) type, price, and size of all foods and beverages and 2) healthfulness of items offered (based on NEMS-V categorization). Two researchers independently double coded NEMS-V data. We used geospatial analysis to examine proximity of rest areas to food stores. We analyzed data by using univariate and bivariate analysis. RESULTS: The mean number of vending machines per site was 8.0 (range, 2-12, standard deviation, 2.8). The healthfulness of offerings varied across sites. Most food items (88.1%; 2,922 of 3,315) and beverage items (63.7%; 1,567 of 2,459) were classified as least healthful. Cold beverage machines had a greater percentage of healthful items (38.2%; 778 of 2,036) than snack machines (11.4%; 374 of 3,270) (P < .001), mainly because of water and diet soda in beverage machines. CONCLUSION: Policy changes are needed to increase the number and presentation of healthful food options at highway rest areas. Policy changes could provide travelers with more healthful options conveniently located along their travel route.
