Leveraging Multiyear, Geospatial Social Media Data for Health Policy Evaluations: Lessons From the Philadelphia Beverage Tax.

CONTEXT: Public reactions to health policies are vital to understand policy sustainability and impact but have been elusively difficult to dynamically measure. The 2021 launch of the Twitter Academic Application Programming Interface (API), allowing for historical tweet analyses, represents a potentially powerful tool for complex, comprehensive policy analyses. OBJECTIVE: Using the Philadelphia Beverage Tax (implemented January 2017) as a case study, this research extracted longitudinal and geographic changes in sentiments, and key influencers in policy-related conversations. DESIGN: The Twitter API was used to retrieve all publicly available tweets related to the Tax between 2016 and 2019. SETTING: Twitter. PARTICIPANTS: Users who posted publicly available tweets related to the Philadelphia Beverage Tax (PBT). MAIN OUTCOME: Tweet content, frequency, sentiment, and user-related information. MEASURES: Tweet content, authors, engagement, and location were analyzed in parallel to key PBT events. Published emotional lexicons were used for sentiment analyses. RESULTS: A total of 45 891 tweets were retrieved (1311 with geolocation data). Changes in the tweet volume and sentiment were strongly driven by Tax-related litigation. While anger and fear increased in the months prior to the policy's implementation, they progressively decreased after its implementation; trust displayed an inverse trend. The 50 tweeters with the highest positive engagement included media outlets (n = 24), displaying particularly high tweet volume/engagement, and public personalities (n = 10), displaying the greatest polarization in tweet sentiment. Most geo-located tweets, reflecting 321 unique locations, were from the Philadelphia region (55.2%). Sentiment and positive engagement varied, although concentrations of negative sentiments were observed in some Philadelphia suburbs. CONCLUSIONS: Findings highlighted how longitudinal Twitter data can be leveraged to deconstruct specific, dynamic insights on public policy reactions and information dissemination to inform better policy implementation and evaluation (eg, anticipating catalysts for both heightened public interest and geographic, sentiment changes in policy conversations). This study provides policymakers a blueprint to conduct similar cost and time efficient yet dynamic and multifaceted health policy evaluations.

A click too far from fresh foods: A mixed methods comparison of online and in-store grocery behaviors among low-income households.

A recent policy in the U.S. authorized monthly benefits from a nutrition assistance program - Supplemental Nutrition Assistance Program (SNAP) - to be used online to increase grocery access and promote healthy eating. This study examined online grocery attitudes and purchasing behaviors among low-income SNAP-eligible households with young children with and without online grocery experience. An explanatory sequential mixed methods design was used, including a survey informed by the theory of planned behavior (TPB) and focus groups conducted between November-March 2021. In the quantitative phase, 310 Maryland residents completed an online survey assessing TPB constructs (attitudes, social norms, perceived control), and food purchase frequency online and in-store. Subsequently, 42 participated in the qualitative phase. Differences in TPB constructs and food purchases were compared between families with and without online grocery experience. Online food selection and fees were a common obstacle to online grocery purchasing. Families who had purchased groceries online (57%) had more positive attitudes and perceived fewer barriers to online shopping than those who had not. Self-reported frequency of buying fresh produce (OR = 0.34, p < 0.001), meat and seafood (OR = 0.29, p < 0.001), and sweets (OR = 0.54, p = 0.005) were lower online than in-store. Families discussed mistrust of online hired shoppers and fewer impulse purchases online as reasons for less frequent purchases of produce and sweets, respectively. Successful scale-up of the U.S. policy must address barriers to healthier purchasing behaviors to effectively promote equitable food access, such as decreasing delivery fees and improving the online food selection.

All Children Thrive: Integration of Nutrition and Early Childhood Development.

Building on the successes of child survival, we review the evidence needed to ensure both that children who survive also thrive and that recommendations promote equity, with no child left behind. To illustrate the critical roles played by nutrition and child development, we revise the Conceptual Framework for the Causes of Malnutrition and Death and the Nurturing Care Framework to create the Conceptual Framework of All Children Surviving and Thriving. The revised framework highlights the goals of child growth and development, supported by health, nutrition, learning, responsive caregiving, and security and safety. We review the challenges posed by undernutrition, stunting, micronutrient deficiencies, overweight, and children not reaching their developmental potential. Although integrated nutrition-childhood development interventions have shown promising effects, most have not been implemented at scale. Implementation science that investigates how and why integrated interventions work in real life, along with the acceptability, feasibility, cost, coverage, and sustainability of the interventions, is needed to ensure equity for all children thriving.

Longitudinal Associations Among Diet Quality, Physical Activity and Sleep Onset Consistency With Body Mass Index z-Score Among Toddlers in Low-income Families.

BACKGROUND: Habits surrounding health behaviors (i.e., sleep, physical activity, diet) are developed in toddlerhood. Lack of consistent health habits may increase obesity risk among toddlers in low-income families. PURPOSE: To compare the role of sleep onset consistency, physical activity and diet quality as mediators between household poverty and toddler weight. METHODS: Two hundred and seven toddlers (mean age = 20.2 months, 46% female, 68.1% Black) participating in an obesity prevention trial were assessed at three time points over 12 months. Using Actical accelerometers, we assessed sleep and physical activity at each time point for up to 1 week. We defined sleep onset consistency as the standard deviation of sleep onset across all days. We calculated the Healthy Eating Index-2015 from a 24-hr dietary recall. We used WHO standards to calculate BMI-for-age z-scores from toddlers' weight/length, and calculated poverty ratio from parent-reported income and family size. Multilevel mediation models tested toddler sleep onset consistency, physical activity, and diet quality as mediators between household poverty and toddler BMI z-score. RESULTS: Toddlers from households with higher poverty ratios had more inconsistent sleep onset times. Toddlers with more inconsistent sleep onset times had higher BMI z-scores across all timepoints, even when accounting for physical activity and diet quality. Sleep onset consistency indirectly explained the association between household poverty and BMI z-score. CONCLUSIONS: Inconsistent sleep schedules could help explain the association between poverty and BMI. Future research should examine strategies to support low-income families to develop and maintain routines as a mechanism to prevent obesity and reduce disparities.

Pre-pandemic to early-pandemic changes in risk of household food insecurity among Maryland families with children.

OBJECTIVE: The objective was to examine risk and protective factors associated with pre- to early-pandemic changes in risk of household food insecurity (FI). DESIGN: We re-enrolled families from two statewide studies (2017-2020) in an observational cohort (May-August 2020). Caregivers reported on risk of household FI, demographics, pandemic-related hardships, and participation in safety net programs (e.g. CARES stimulus payment, school meals). SETTING: Maryland, United States. PARTICIPANTS: Economically, geographically, and racially/ethnically diverse families with preschool to adolescent-age children. Eligibility included reported receipt or expected receipt of the CARES stimulus payment or a pandemic-related economic hardship (n=496). RESULTS: Prevalence of risk of FI was unchanged (pre-pandemic: 22%, early-pandemic: 25%, p=0.27). Risk of early-pandemic FI was elevated for non-Hispanic Black (aRR=2.1 [95% CI 1.1, 4.0]) and Other families (aRR=2.6 [1.3, 5.4]) and families earning ≤300% federal poverty level. Among pre-pandemic food secure families, decreased income, job loss, and reduced hours were associated with increased early-pandemic FI risk (aRR=2.1 [1.2, 3.6] to 2.5 [1.5, 4.1]); CARES stimulus payment (aRR=0.5 [0.3, 0.9]) and continued school meal participation (aRR=0.2 [0.1, 0.9]) were associated with decreased risk. Among families at risk of FI pre-pandemic, safety net program participation was not associated with early-pandemic FI risk. CONCLUSIONS: The CARES stimulus payment and continued school meal participation protected pre-pandemic food secure families from early-pandemic FI risk but did not protect families who were at risk of FI pre-pandemic. Mitigating pre-pandemic FI risk and providing stimulus payments and school meals may support children's health and reduce disparities in response to pandemics.

Implementation of a multilevel, multicomponent intervention for obesity control in Native American communities (OPREVENT2): challenges and lessons learned.

OPREVENT2 was a multilevel, multicomponent (MLMC) adult obesity prevention that sought to improve access and demand for healthier food and physical activity opportunities in six Native American communities in the Southwest and Midwest. OPREVENT2 worked with worksites, food stores, schools (grades 2-6), through social media and mailings, and with a local community action committee (CAC), in each of the three intervention communities, and was implemented in six phases. We conducted a process evaluation to assess implementation of each intervention component in terms of reach, dose delivered and fidelity. Implementation of each component was classified as high, medium or low according to set standards, and reported back at the end of each phase, allowing for improvements. The school and worksite components were implemented with high reach, dose delivered and fidelity, with improvement over time. The school program had only moderate reach and dose delivered, as did the social media component. The CAC achieved high reach and dose delivered. Overall, study reach and dose delivered reached a high implementation level, whereas fidelity was medium. Great challenges exist in the consistent implementation of MLMC interventions. The detailed process evaluation of the OPREVENT2 trial allowed us to carefully assess the relative strengths and limitations of each intervention component.

Maternal anxiety and diet quality among mothers and toddlers from low-income households.

We evaluated the association between maternal anxiety score and diet quality over time among mothers and toddlers in low-income families. Longitudinal data were collected from 267 mother-toddler dyads in an obesity prevention trial. Participants were recruited from the Special Supplemental Nutrition Program for Women, Infants and Children and paediatric clinics between 2007 and 2010. Dyads were assessed at study enrolment (Time 1), 6-month (Time 2), and 12-month follow-up (Time 3). On the basis of a 1-day 24-hr dietary recall, we estimated maternal and toddler diet quality using the Healthy Eating Index 2015. Anxiety, a time-varying variable, was assessed via the State-Trait Anxiety Inventory. Associations between maternal anxiety score and maternal and toddler diet quality over time were assessed in adjusted mixed models. Maternal and toddler diet quality were positively correlated (r = .48, p < .001). Higher maternal anxiety scores were related to lower toddler Healthy Eating Index scores (b = -0.51, 95% confidence interval, CI [-0.87, -0.15]) with no significant variation over time. The relation between maternal diet quality and anxiety score varied over time (b = 0.28, p = .03, for time-anxiety interaction). Higher maternal anxiety scores were associated with lower maternal diet quality at Time 1 (b = -0.71, 95% CI [-1.09, 0.34]) and at Time 2 (b = -0.51, 95% CI [-0.97, -0.05]), but not at Time 3 (b = -0.14, 95% CI [-0.54, 0.26]). Findings suggest that mothers and toddlers exhibited similar low-quality dietary patterns and that lower diet quality was associated with higher maternal anxiety scores. Approaches to enhance diet quality may consider incorporating anxiety-reducing strategies into maternal and toddler care and feeding behaviour guidelines.

Dietary Intake of Upper Midwest and Southwest Native American Adults.

Limited information on current dietary patterns of Native American (NA) adults exists. This paper describes the dietary intake of 582 NA adults, aged 19-75 years, living in six communities in New Mexico and Wisconsin in 2016-2017 and compares macronutrient and micronutrient intakes, estimated via a semi-quantitative 30-day Block Food Frequency Questionnaire, among different age and sex groups. NA adults consumed a diet high in % energy from total fat, saturated fat, added sugars, and sodium. A general trend of lower micronutrient intakes with increasing age was observed. Health professionals can apply this information to develop effective and culturally relevant nutrition interventions.

A multilevel, multicomponent childhood obesity prevention group-randomized controlled trial improves healthier food purchasing and reduces sweet-snack consumption among low-income African-American youth.

BACKGROUND: Consumption of foods and beverages rich in sugar remains high across all races and ages in the United States. Interventions to address childhood obesity and decrease sugar intake are needed, particularly in low-income settings. METHODS: B'more Healthy Communities for Kids (BHCK) was a group-randomized, controlled trial implemented among 9-15-year olds in 30 low-income areas of Baltimore. We increased access to low-sugar foods and beverages at wholesalers and small food stores. Concurrently, we encouraged their purchase and consumption by children through youth-led nutrition education in recreation centers, in-store promotions, text messaging and a social media program directed at caregivers. Sugar consumption (sugar sweetened beverage (SSB), sweets) in youth was assessed pre- (n = 534) and post-intervention (n = 401) using the Block Kids Food Frequency Questionnaire. Purchasing of 38 healthier and 28 less healthier food/beverage varieties in the previous 7 days was assessed via self-report. Multilevel models at the community and individual levels were used. Analyses were stratified by age (younger: 9-12-year olds (n = 339) vs older: 13-15 (n = 170)). Models were controlled for child's sex, race, total daily caloric intake, and caregiver's age and sex. RESULTS: Overall baseline mean healthier food purchasing was 2.5 (+ 3.6; min. 0, max. 34 items per week), and unhealthier food purchasing 4.6 (+ 3.7; 0-19 items per week). Mean intake at baseline for kcal from SSB was 176 (+ 189.1) and 153 (+ 142.5), and % of calories from sweets (i.e. cookies, cakes, pies, donuts, candy, ice cream, sweetened cereals, and chocolate beverages) was 15.9 (+ 9.7) and 15.9 (+ 7.7) in comparison and intervention youth, respectively. Intervention youth increased healthier foods and beverages purchases by 1.4 more items per week than comparison youth (ß = 1.4; 95% CI: 0.1; 2.8). After the intervention, there was a 3.5% decrease in kcal from sweets for older intervention youth, compared to the control group (ß = - 3.5; 95% CI: -7.76; - 0.05). No impact was seen on SSB consumption. CONCLUSION: BHCK successfully increased healthier food purchasing variety in youth, and decreased % calories from sweet snacks in older youth. Multilevel, multicomponent environmental childhood obesity programs are a promising strategy to improve eating behaviors among low-income urban youth. TRIAL REGISTRATION: NCT02181010 (July 2, 2014, retrospectively registered).

Implementation of Text-Messaging and Social Media Strategies in a Multilevel Childhood Obesity Prevention Intervention: Process Evaluation Results.

Social media and text messaging show promise as public health interventions, but little evaluation of implementation exists. The B'more Healthy Communities for Kids (BHCK) was a multilevel, multicomponent (wholesalers, food stores, recreation centers) childhood obesity prevention trial that included social media and text-messaging components. The BHCK was implemented in 28 low-income areas of Baltimore City, Maryland, in 2 waves. The texting intervention targeted 241 low-income African American caregivers (of 283), who received 3 texts/week reinforcing key messages, providing nutrition information, and weekly goals. Regular posting on social media platforms (Facebook, Instagram, Twitter) targeted community members and local stakeholders. High implementation standards were set a priori (57 for social media, 11 for texting), with low implementation defined as <50%, medium as 50% to 99%, high as ≥100% of the high standard for each measure. Reach, dose delivered, and fidelity were assessed via web-based analytic tools. Between waves, social media implementation improved from low-moderate to high reach, dose delivered, and fidelity. Text messaging increased from moderate to high in reach and dose delivered, fidelity decreased from high to moderate. Data were used to monitor and revise the BHCK intervention throughout implementation. Our model for evaluating text messaging-based and social media-based interventions may be applicable to other settings.

A Youth-Leader Program in Baltimore City Recreation Centers: Lessons Learned and Applications.

Peer-led interventions may be an effective means of addressing the childhood obesity epidemic; however, few studies have looked at the long-term sustainability of such programs. As part of a multilevel obesity prevention intervention, B'More Healthy Communities for Kids, 16 Baltimore college students were trained as youth-leaders (YLs) to deliver a skill-based nutrition curriculum to low-income African American children (10-14 years old). In April 2015, formative research was used to inform sustainability of the YL program in recreation centers. In-depth interviews were conducted with recreation center directors ( n = 4) and the YLs ( n = 16). Two focus groups were conducted with YLs ( n = 7) and community youth-advocates ( n = 10). Barriers to this program included difficulties with transportation, time constraints, and recruiting youth. Lessons learned indicated that improving trainings and incentives to youth were identified as essential strategies to foster continuity of the youth-led program and capacity building. High school students living close to the centers were identified as potential candidates to lead the program. Based on our findings, the initial intervention will be expanded into a sustainable model for implementation, using a train-the-trainer approach to empower community youth to be change agents of the food environment and role models.

Factors Associated with Home Meal Preparation and Fast-Food Sources Use among Low-Income Urban African American Adults.

This study aimed to assess the factors associated with home meal preparation (HMP) and fast-food sources use (FFS) frequencies of low-income African-American adults and their healthy food beliefs and attitudes, food-related psychosocial factors, food acquisition patterns, food sources use, and BMI. We used cross-sectional data from 295 adults living in Baltimore, USA. HMP was inversely associated with FFS, which had lower odds of HMP ≥1 time/day and higher BMI scores. HMP was positively associated with positive beliefs and self-efficacy toward healthy foods, getting food from healthier food sources, and lower FFS. Higher odds of HMP ≥1 time/day were associated with getting food from farmers' market and supermarkets or grocery stores. FFS had an inverse association with positive beliefs and self-efficacy toward healthy foods, and a positive association with less healthy food acquisition scores. Higher odds of FFS ≥1 time/week were associated with getting food from corner stores, sit-down restaurants, and convenience stores.

Patterns of Food Consumption are Associated with Obesity, Self-Reported Diabetes and Cardiovascular Disease in Five American Indian Communities.

The relationship between dietary patterns and chronic disease is underexplored in indigenous populations. We assessed diets of 424 American Indian (AI) adults living in 5 rural AI communities. We identified four food patterns. Increased prevalence for cardiovascular disease was highly associated with the consumption of unhealthy snacks and high fat-food patterns (OR 3.6, CI=1.06, 12.3; and OR 6.0, CI=1.63, 22.1), respectively. Moreover, the food-consumption pattern appeared to be different by community setting (p<.05). We recommend culturally appropriate community-intervention programs to promote healthy behavior and to prevent diet-related chronic diseases in this high-risk population.

Preschoolers' Self-Regulation and Behavior Problems in the Midst of Caregiver Depression and Chaos.

OBJECTIVES: Preschoolers' self-regulation is partially developed through home and child care routines. COVID-19-related child care closures increased caregiver depressive symptoms, household chaos, and children's behavior problems. This longitudinal study examined how preschoolers' prepandemic self-regulation was related to behavior problems early in the pandemic, including buffering against the adverse effects of caregiver depressive symptoms and household chaos. METHODS: A sample of 264 caregivers of preschoolers reported on their children's self-regulation (Behavior Rating Inventory of Executive Function-Preschool Version Inhibitory Self Control Index) before the pandemic and caregiver depressive symptoms (Center for Epidemiological Studies), household chaos (Confusion, Hubbub, and Order Scale), and children's behavior problems (Behavior Rating Index for Children) during the pandemic. We used linear mixed models to examine predictors of children's behavior problems, including prepandemic self-regulation, and further examined moderation by pandemic-related caregiver depressive symptoms and household chaos. RESULTS: Children were 64% non-Hispanic White and 24% non-Hispanic Black, with mean pandemic age 5.9 years. Prepandemic self-regulation significantly predicted early pandemic behavior problems (ß = -0.38 [95% confidence interval, -0.69 to -0.07]). This association was moderated by pandemic-related caregiver depressive symptoms and household chaos; the protective association was maintained at high levels of caregiver depressive symptoms or household chaos, although the association diminished when these co-occurred. CONCLUSION: The protective association between prepandemic self-regulation and subsequent behavior problems suggests longitudinal benefits of preschoolers' inhibitory and emotional control. Despite reduced protection associated with co-occurring caregiver and household challenges, self-regulation continued to demonstrate protection against subsequent behavior problems, even in the midst of a pandemic.

"I Don't Want an App to Do the Work for Me": A Qualitative Study on the Perception of Online Grocery Shopping From Small Food Retailers.

BACKGROUND: Small food retailers often stock energy-dense convenience foods, and they are ubiquitous in low-income urban settings. With the rise in e-commerce, little is known about the acceptability of online grocery shopping from small food retailers. OBJECTIVE: To explore perceptions of the role of small food retailers (bodegas) in food access and the acceptability of online grocery shopping from bodegas among customers and owners in a diverse New York City urban neighborhood with low incomes. DESIGN: In-depth interviews were conducted with bodega owners and adult customers between May and July 2022. PARTICIPANTS/SETTING: Bodega owners who either had (n = 4) or had not (n = 2) implemented a locally designed online grocery system. Customers (n = 25) were recruited through purposive sampling and were eligible if they purchased at bodegas (>once per month), had low income (household income ≤130% of the federal poverty level or Supplemental Nutrition Assistance Program [SNAP] participants), and owned smartphones. ANALYSES PERFORMED: All interviews were transcribed and analyzed in MAXQDA (Verbi Software, Berlin, Germany), using grounded theory. RESULTS: To owners and customers, bodegas were seen as good neighbors providing culturally appropriate foods and an informal financial safety net. Their perceptions concerning food cost and availability of healthy foods in bodegas diverged. Although most perceived online grocery from bodegas as a positive community resource, they also believed it was not suited to their own community because of the bodega's proximity to customers' homes and the low digital literacy of some community members. Customers reported social norms of pride in not using online grocery shopping. Owners and customers believed the service would more likely be used if government benefits such as SNAP allowed payment for online orders. Both suggested improved outreach to increase program awareness and uptake. CONCLUSIONS: Online grocery shopping from small food retailers may be acceptable in urban communities with low income and was perceived as a community resource. However, important barriers need to be addressed, such as social norms related to pride in not using online grocery services, digital literacy, program awareness, and allowing SNAP payment for online orders from bodegas.

An equity-oriented systematic review of online grocery shopping among low-income populations: implications for policy and research.

CONTEXT: Online grocery services are an emerging component of the food system with the potential to address disparities in access to healthy food. OBJECTIVE: We assessed the barriers and facilitators of equitable access to healthy foods in the online grocery environment, and the psychosocial, purchasing, and dietary behaviors related to its use among low-income, diverse populations. DATA SOURCES: Four electronic databases were searched to identify relevant literature; 16 studies were identified. RESULTS: Barriers to equitable access to healthy food included cost and limited availability of online grocery services in food deserts and rural areas. The expansion of online grocery services and the ability to use nutrition assistance benefits online were equity-promoting factors. Perceived low control over food selection was a psychosocial factor that discouraged online grocery use, whereas convenience and lower perceived stress were facilitators. Findings were mixed regarding healthfulness of foods purchased online. Although few studies assessed diet, healthy food consumption was associated with online grocery use. CONCLUSION: Researchers should assess the impact of online grocery shopping on low-income families' food purchases and diet. SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration no. CRD: 42021240277.

Giving Families a Voice for Equitable Healthy Food Access in the Wake of Online Grocery Shopping.

Understanding the views of families from low-income backgrounds about inequities in healthy food access and grocery purchase is critical to food access policies. This study explored perspectives of families eligible for the Supplemental Nutrition Assistance Program (SNAP) on healthy food access in physical and online grocery environments. The qualitative design used purposive sampling of 44 primary household food purchasers with children (aged ≤ 8), between November 2020-March 2021, through 11 online focus groups and 5 in-depth interviews. Grounded theory was used to identify community-level perceived inequities, including influences of COVID-19 pandemic, SNAP and online grocery services. The most salient perceived causes of inequitable food access were neighborhood resource deficiencies and public transportation limitations. Rural communities, people with disabilities, older adults, racially and ethnically diverse groups were perceived to be disproportionately impacted by food inequities, which were exacerbated by the pandemic. The ability to use SNAP benefits to buy foods online facilitated healthy food access. Delivery fees and lack of control over food selection were barriers. Barriers to healthy food access aggravated by SNAP included social stigma, inability to acquire cooked meals, and inadequate amount of monthly funds. Findings provide a foundation for policy redesign to promote equitable healthy food systems.

Equity-Promoting Strategies in Online Grocery Shopping: Recommendations Provided by Households of Low Income.

OBJECTIVE: To explore barriers and facilitators of online grocery shopping and identify community-driven strategies to promote equity in online food access. DESIGN: This qualitative study used a purposive recruitment strategy to conduct 11 focus groups and 5 in-depth interviews between November 2020 and March 2021. SETTING: Data collection was conducted virtually with participants residing in diverse (majority urban) regions of Maryland. PARICIPANTS: 44 primary household food purchasers with young children (aged < 8 years) eligible for the Supplemental Nutrition Assistance Program (SNAP). PHENOMENON OF INTEREST: Barriers and facilitators of online grocery shopping and strategies elicited by the community to leverage SNAP and online food retailer services to reduce inequities in healthy food access. ANALYSIS: We coded and analyzed transcripts on the basis of the Socioecological Model, Theory of Planned Behavior, and an Equity-Oriented Framework. RESULTS: Overall, we identified 10 themes across all socioecological levels, all of which reflected both barriers and facilitators to online shopping: (1) individual: trust of shoppers, technology, (2) interpersonal: spousal/children needs, (3) community: safety and security, (4) organizational: retail experience and food quality, and (5) policy: SNAP and structural inequities. Participant recommendations included improving food access and communication with hired shoppers, implementing more payment/cost-saving options, and offering educational programming for SNAP participants on using benefits online. CONCLUSIONS AND IMPLICATIONS: Households of low-income identified barriers and facilitators of online grocery shopping across the socioecological levels, emphasizing the need for a multilevel approach to equity promotion. We recommend future work to explore the suggested actionable pathways, which involve delivery providers, grocery stores, nutrition educators, and policymakers leveraging online grocery features (ie, meal planning support) and policies (ie, expansion of the SNAP Online Purchasing Pilot to more retailers) to reducing deterrents (ie, delivery fees waived) for an equity-promoting online grocery environment.

Online Pilot Grocery Intervention among Rural and Urban Residents Aimed to Improve Purchasing Habits.

Online grocery shopping has the potential to improve access to food, particularly among low-income households located in urban food deserts and rural communities. The primary aim of this pilot intervention was to test whether a three-armed online grocery trial improved fruit and vegetable (F&V) purchases. Rural and urban adults across seven counties in Kentucky, Maryland, and North Carolina were recruited to participate in an 8-week intervention in fall 2021. A total of 184 adults were enrolled into the following groups: (1) brick-and-mortar "BM" (control participants only received reminders to submit weekly grocery shopping receipts); (2) online-only with no support "O" (participants received weekly reminders to grocery shop online and to submit itemized receipts); and (3) online shopping with intervention nudges "O+I" (participants received nudges three times per week to grocery shop online, meal ideas, recipes, Facebook group support, and weekly reminders to shop online and to submit itemized receipts). On average, reported food spending on F/V by the O+I participants was USD 6.84 more compared to the BM arm. Online shopping with behavioral nudges and nutrition information shows great promise for helping customers in diverse locations to navigate the increasing presence of online grocery shopping platforms and to improve F&V purchases.
