Examining disparities in diet quality between SNAP participants and non-participants using Oaxaca-Blinder decomposition analysis

Protocol for exploring pathways to equitable outcomes in post-stroke aphasia and dysphagia

INTRODUCTION

Longstanding racial disparities in stroke-related outcomes have been well documented. However, the underlying causes of observed disparities have neither been clearly determined nor have strategies to mitigate disparities been developed. Evidence suggests that racial disparities may be partially explained by structural barriers that can arise from implicit and explicit provider biases, institutional practices, public policies, or characteristics of the community where patients reside and recover from their conditions. The objective of this study is to move beyond traditional measures of disparities by identifying the mechanisms that drive these observed disparities in aphasia and dysphagia across the continuum of care. In this study we will follow stroke survivors for 12 months post-discharge, which will allow us to examine the patient, provider, health system, and administrative factors that impact their aphasia and dysphagia recovery.

METHODS

This study will utilize a 100% sample of Medicare fee-for-service claims data for persons hospitalized for stroke. Patients discharged from acute stroke care will be followed for at least 12 months to measure the timing of post-acute care transition(s) and post-acute care speech-language pathology (SLP) utilization. Functional communication and swallowing outcomes will be measured at initiation, conclusion of post-acute care treatment, and points in-between allowing us to link improvement of functional communication (i.e., aphasia) and swallowing ability (i.e., dysphagia) to aphasia/dysphagia treatments as patients transition through post-acute settings. Then, using regression decomposition methods, we will examine the relationships between race and: (a) where patients receive treatment, (b) the timing of transition between sites of care, and (c) the quality of care received. Decomposition methods will allow us to elucidate the multiple factors that contribute to underlying observed health disparities by quantifying the extent to which differences between the outcomes of two groups are explained by 1) differential endowments or characteristics, such as geographic access, education, risk factors, or insurance coverage; or 2) differences in decision-making, defined as between group differences in outcomes despite equal endowments or unmeasured differences.

DISCUSSION

We hypothesize that racial disparities in aphasia and dysphagia outcomes will not only result from differences in the quantity and timing of services provided in the post-acute and community settings, but also structural differences at the community level. These findings will provide a more comprehensive understanding of healthcare use and outcomes.

Association between participation in the supplemental nutrition assistance program and perception of limited availability and choice of healthy foods

BACKGROUND

Nutrition security encompasses stable and equitable access, availability, affordability, and utilization of healthy foods.

AIM

To evaluate the relationship of two newly created dichotomous measures that represent aspects of nutrition security (i.e., perceived limited availability and healthfulness choice) with Supplemental Nutrition Assistance Program (SNAP) participation.

METHODS

Logistic regression models were run for each outcome separately with adjustment for age, income-to-poverty ratio, gender, education, race, and food security.

RESULTS

Adults using social services (e.g., food pantries) were enrolled (N = 402) in this cross-sectional analysis. SNAP participants (61.7%) were not different from non-SNAP participants in perceiving limited availability (aOR [95% CI]: 1.21 [0.75, 1.95]) or limited ability to choose (aOR [95% CI]: 0.69 [0.43, 1.12]) healthy foods.

CONCLUSIONS

Both SNAP and non-SNAP participants with low socioeconomic status report limited availability of healthy foods in their environment and a limited ability to choose healthy foods.

Experiences participating in federal nutrition assistance programs during the early months of the COVID-19 pandemic: an investigation in Vermont

BACKGROUND

Federal nutrition assistance programs serve as safety nets for many American households, and participation has been linked to increased food security and, in some instances, improved diet quality and mental health outcomes. The COVID-19 pandemic brought new and increased economic, social, and psychological challenges, necessitating inquiry into how nutrition assistance programs are functioning and associated with public health outcomes.

METHODS

Using data from a representative statewide survey administered in Vermont (n = 600) between July and September 2020, we examined participant experiences with major federal nutrition assistance programs: the Supplemental Nutrition Assistance Program (SNAP), the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), and school meal programs. We explored quantitative and qualitative responses regarding perceptions of program utility, and used nearest neighbors matching analyses in combination with bivariate statistical tests to assess associations between program participation and food insecurity, perceived stress, and fruit and vegetable intake as indicators of dietary quality.

RESULTS

One in four respondents (27.3%) used at least one federal nutrition assistance program. As compared to non-participants, we found higher rates of food insecurity among program participants (57.5% vs. 18.1%; p < 0.001), an association that persisted even when we compared similar households using matching techniques (p ≤ 0.001). From matched analyses, we found that, compared to low-income non-participants, low-income program participants were less likely to meet fruit intake recommendations (p = 0.048) and that low-income SNAP and WIC participants were less likely to meet vegetable intake recommendations (p = 0.035). We also found lower rates of perceived stress among low-income school meal participant households compared to low-income non-participants (p = 0.039). Despite these mixed outcomes, participants broadly valued federal nutrition assistance programs, characterizing them as helpful or easy to use.

CONCLUSIONS

We found that federal nutrition assistance programs as a group were not sufficient to address food insecurity and stress or increase fruit and vegetable intake in the state of Vermont during the early months of the COVID-19 pandemic. Nonetheless, participants perceived benefits from participation in these programs. Optimizing the utility of nutrition assistance programs depends on critical examination of their functioning under conditions of great stress.

Are Supplemental Nutrition Assistance Program Restrictions on Sugar-Sweetened Beverages Effective in Reducing Purchase or Consumption? A Systematic Review

The participants in the Supplemental Nutrition Assistance Program (SNAP) consume greater amounts of sugar and sweetened beverages (SSBs) compared to non-eligible individuals, which could result in potential negative health outcomes. This can be attributed to the lack of restrictions on SSB purchases with SNAP benefits. In view of the increasing calls from advocates and policymakers to restrict the purchase of SSBs with SNAP benefits, we performed a systematic review to assess its impact towards SSB purchases and consumption. We searched articles from five databases-Cochrane, EBSCO, SCOPUS, Web of Science, and PubMed-and selected seven studies, four of which were randomized controlled trials (RCTs) and three were simulation modeling studies. All three simulation studies and one RCT reported outcomes in terms of consumption, while the other three RCTs reported outcomes in terms of purchases. All seven studies found that an SSB restriction led to a decrease in SSB consumption or purchases, with six studies reporting significant results. Nonetheless, limitations exist. These include limited studies on this subject, potential workarounds circumventing SSB restrictions, like making purchases using personal cash, potentially differed estimated effects when combined with incentives or other initiatives, and the limited geographical scope among the selected RCTs.

Healthy eating and active living policy, systems, and environmental changes in rural Louisiana: a contextual inquiry to inform implementation strategies

BACKGROUND

Healthy eating and active living policy, systems, and environmental (PSE) changes are implemented across the United States through Cooperative Extension. However, translating multisector PSE changes to practice in community settings is challenging and there is a lack of knowledge about barriers and facilitators to PSE changes among state Extension systems using standardized frameworks. Therefore, a research-to-practice partnership effort aimed to identify Louisiana Cooperative Extension Service Family and Consumer Science (LFCS) practitioners' barriers and facilitators to implementing PSE changes in rural Louisiana communities.

METHODS

A qualitative approach using the 2022 Consolidated Framework for Implementation Research (2022 CFIR) was used. Focus group discussions were conducted at five LFCS regional trainings between February and May 2022. All LFCS practitioners with any level of experience implementing healthy eating and active living PSE changes were eligible to participate, with emphasis on understanding efforts within more rural communities. Focus group discussions were audio-recorded and transcribed verbatim. Researchers analyzed qualitative data using the constant comparison method and 2022 CFIR domains and constructs including Inner Setting (LFCS organization), Outer Setting (rural Louisiana communities), Innovation (PSE changes), and Individuals (PSE change implementation actors/partners).

RESULTS

Across the five regions, LFCS practitioners (n = 40) described more barriers (n = 210) than facilitators (n = 100); findings were often coded with multiple 2022 CFIR domains. Reported Inner Setting barriers were lack of formal or informal information sharing and lack of access to knowledge and information. Outer Setting barriers included sustaining and initiating community partnerships and local environmental or political conditions. Individual barriers included a lack of time and expertise, and Innovation barriers included the complex nature of rural PSE changes. Facilitators were mentioned at multiple levels and included community partner buy-in and practitioners' motivation to implement PSE changes.

CONCLUSIONS

Implementation strategies are needed to build on organizational strengths and to overcome multi-level barriers to PSE change implementation among LFCS practitioners. The results from the in-depth contextual inquiry used could serve as a guide for future pragmatic assessment efforts among other state Extension systems or as a model for identifying barriers and facilitators and associated implementation strategies among other public health systems in the U.S. and abroad.

Food Insecurity Among Individuals With Cardiovascular Disease and Cardiometabolic Risk Factors Across Race and Ethnicity in 1999-2018

Importance

Food insecurity is a risk factor for poor cardiovascular outcomes that occur disproportionately among individuals from racial and ethnic minority backgrounds who have cardiovascular disease (CVD) or cardiometabolic risk factors.

Objective

To assess long-term prevalence of food insecurity among those with CVD or cardiometabolic risk factors in the United States.

Design, Setting, and Participants

This serial cross-sectional study includes data for noninstitutionalized US adults from the National Health and Nutrition Examination Survey (1999-2018).

Main Outcomes and Measures

Food insecurity was assessed using the US Department of Agriculture Adult Food Security Survey Module. We estimated prevalence of food insecurity among adults with prior CVD (myocardial infarction, stroke, heart failure) and cardiometabolic risk factors (hypertension, diabetes, obesity, hyperlipidemia) across racial and ethnic groups and prevalence of Supplemental Nutrition Assistance Program (SNAP) participation among those reporting food insecurity.

Results

In the analytic sample of 57 517 adults, 6770 individuals (11.8%) reported food insecurity, which was more prevalent among Hispanic (1938 [24.0%]) and non-Hispanic Black (1202 [18.2%]) than non-Hispanic Asian (100 [8.0%]) and non-Hispanic White adults (3221 [8.5%]). Among 57 517 adults, 4527 (7.9%) had any CVD, 2933 (5.1%) coronary artery disease, 1536 (2.7%) stroke, 1363 (2.4%) heart failure, 28 528 (49.6%) hypertension, 17 979 (33.2%) obesity, 6418 (11.2%) diabetes, and 19 178 (30.8%) dyslipidemia. All CVD and cardiometabolic diseases except coronary artery disease were more prevalent among those with food insecurity. Food insecurity increased over time and was more frequent for patients with CVD but not for cardiometabolic risk factors. From 2011 to 2018, non-Hispanic Black adults with CVD had a decrease in food insecurity prevalence (36.6%; 95% CI, 23.9%-49.4%, to 25.4%; 95% CI, 21.4%-29.3%; P = .04 for trend), whereas adults of other races and ethnicities or data based on cardiometabolic risk factors had no significant change. For individuals who had food insecurity, SNAP participation was higher among those with CVD vs without CVD (54.2%; 95% CI, 46.6%-61.8%, vs 44.3%; 95% CI, 40.5%-48.1%; P = .01).

Conclusions and Relevance

The prevalence of food insecurity among patients with CVD increased over time. Although members of non-Hispanic Black and Hispanic groups had the highest food insecurity, non-Hispanic Black individuals with CVD were the only group to have a significant decrease in food insecurity since 2011. Increased recognition of food insecurity and resources for treating it are needed to address the negative consequences of food insecurity on CVD outcomes.

SNAP and WIC Participation During Childhood and Food Security in Adulthood, 1984-2019

Objectives. To examine the effects of childhood participation in the Supplemental Nutrition Assistance Program (SNAP) and the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) on adult food security in the United States. Methods. We used data from the 1984 to 2019 waves of the Panel Study of Income Dynamics to follow a balanced panel of 1406 individuals from birth through ages 20 to 36 years. We measured food insecurity from 1999 to 2003 and 2015 to 2019 among those who resided in low-income households during childhood. Results. Twenty-eight percent of individuals who resided in low-income households during childhood exhibited improved food security status from childhood to adulthood. Those who participated in SNAP and WIC during childhood had 4.16-fold higher odds (95% confidence interval [CI] = 1.91, 9.03) of being more food secure than those who were eligible for but did not receive SNAP or WIC, and those who participated in SNAP alone had 3.28-fold higher odds (95% CI = 1.56, 6.88). Conclusions. Participation in social safety net programs such as SNAP and WIC during childhood helps to improve food security across the life course. Our findings add evidence regarding the long-term benefits of participation in SNAP and WIC during childhood. (Am J Public Health. 2022;112(10):1498-1506. https://doi.org/10.2105/AJPH.2022.306967).

Improving Fruit and Vegetable Accessibility, Purchasing, and Consumption to Advance Nutrition Security and Health Equity in the United States

In recent years, national and local efforts to improve diet and health in the United States have stressed the importance of nutrition security, which emphasizes consistent access to foods and beverages that promote health and prevent disease among all individuals. At the core of this endeavor is fruit and vegetable (FV) consumption, a dietary practice that is integral to attaining and sustaining a healthy diet. Unfortunately, significant inequities in FV accessibility, purchasing, and consumption exist, particularly among populations that are socially and economically disadvantaged. To achieve nutrition and health equity in the United States, the field must center the goal of nutrition security and initiatives that aim to increase FV consumption, specifically, in future work. The International Journal of Environmental Research and Public Health (IJERPH) Special Issue titled "Nutrition and Health Equity: Revisiting the Importance of Fruit and Vegetable Availability, Purchasing, and Consumption" features several scholarly publications from experts conducting timely research on these topics. In this commentary, we (1) summarize the U.S.-based literature on inequities in FV accessibility, purchasing, and consumption, (2) describe how the contributions to this IJERPH special issue can advance nutrition security and health equity, and (3) outline future research questions from our perspective.

Supplemental Nutrition Assistance Program (SNAP)-authorised store marketing environments in Louisiana encourage the selection of less nutritious foods and beverages

Marketing influences consumers’ dietary purchases. However, little is known about marketing environments in Supplemental Nutrition Assistance Program (SNAP)-authorised stores. The present study explored SNAP-authorised store marketing environments in Louisiana by rurality, store ownership and store type (n 42). Sampling methods were designed to include randomly selected stores in each geographic area of the state. The GroPromo was used to measure placement, promotion, and child-focused aspects of marketing strategies used for healthier (fruits and vegetables) and less healthy products (chips, candy, sugar-sweetened beverages, child-focused cereal) in medium- and high-prominence marketing areas. In using multivariate analysis of variance (MANOVA) (P < 0⋅05) for data analysis, variations in GroPromo scores were found among SNAP-authorised stores by rurality (P < 0⋅05) and store ownership (P < 0⋅001); no differences were found by store type (P > 0⋅05). Future research, practice and policy strategies are required to understand the influence of marketing environments on SNAP participants’ dietary quality and to design responsive public health interventions.

Change in Employment Status Due to the COVID-19 Pandemic, SNAP Participation, and Household Food Insecurity among Black and Latino Adults in Illinois

The onset of the COVID-19 pandemic resulted in record-high unemployment rates. Black and Latino adults experienced disproportionately higher rates of unemployment. We aimed to examine associations between pandemic-related employment status change and household food insecurity among an economically diverse sample of Black and Latino adults in Illinois during the early months of the COVID-19 pandemic. Furthermore, we evaluated the significance of Supplemental Nutrition Assistance Program (SNAP) participation to determine if it modified associations. We analyzed cross-sectional data collected from 1,809 Black and Latino adults in two waves: May 2020 and June/July 2020. Participants listed their change in employment status as “lost job entirely”, “employed, but paid hours reduced”, “employed, but anticipate job lost”, or “no change”. Participants self-reported their SNAP status and completed the USDA’s six item U.S. Food Security Module to report household food security status. We used logistic regression to assess the significance of associations after controlling for socio-demographics. Approximately 15.5% of participants lost their job entirely, 25.2% were SNAP participants, and 51.8% reported low food security (LFS). All changes in employment were significantly associated with increased odds of LFS after adjusting for socio-demographics. SNAP participants who lost their job had higher odds of LFS (OR: 4.69; 95% CI: 2.69–8.17) compared to non-participants who lost their job (OR: 2.97; 95%: 1.95–4.52). In summary, we observed strong associations between changes in employment and household food insecurity, particularly among SNAP participants, which underscores the pandemic’s impact on low-income and minority populations.

A systematic scoping review of the literacy literature to develop a digital food and nutrition literacy model for low-income adults to make healthy choices in the online food retail ecosystem to reduce obesity risk

Adults with lower incomes are disproportionately affected by poverty, food insecurity, obesity, and diet-related non-communicable diseases (NCDs). In 2020-2021 amid the coronavirus disease 2019 (COVID-19) pandemic, the United States Department of Agriculture (USDA) expanded the Supplemental Nutrition Assistance Program (SNAP) Online Purchasing Pilot program to enable eligible participants to purchase groceries online in 47 states. This expansion underscores the need for SNAP adults to have digital literacy skills to make healthy dietary choices online. Currently, a digital literacy model does not exist to help guide USDA nutrition assistance policies and programs, such as SNAP. We conducted a systematic scoping review of the academic and gray literature to identify food, nutrition, health, media, financial, and digital literacy models. The search yielded 40 literacy models and frameworks that we analyzed to develop a Multi-dimensional Digital Food and Nutrition Literacy (MDFNL) model with five literacy levels (i.e., functional, interactive, communicative, critical, and translational) and a cross-cutting digital literacy component. Utilization of the MDFNL model within nutrition assistance policies and programs may improve cognitive, behavioral, food security, and health outcomes and support equity, well-being, digital inclusion, and healthy communities to reduce obesity and NCD risks.

U.S. Fruit and Vegetable Affordability on the Thrifty Food Plan Depends on Purchasing Power and Safety Net Supports

The Supplemental Nutrition Assistance Program (SNAP) increases the food purchasing power of lower-income households so that they can better afford a nutritious diet. Benefit amounts are based in part on the cost for a household to follow the Thrifty Food Plan (TFP), a meal pattern designed to meet the Dietary Guidelines for Americans. In October 2021, the U.S. Department of Agriculture (USDA) reformulated the TFP and increased its cost by 21%. However, the TFP still does not account for differences in food prices across the country. This study examines: (1) how geographic variation in food prices affects fruit and vegetable affordability and (2) to what extent raising the cost of the TFP (and therefore the maximum SNAP benefit) has mitigated these effects. We use data on fruit and vegetable prices from the USDA and simulation techniques to create and cost out food baskets with a sufficient quantity and variety of fruits and vegetables for a representative household to satisfy guidelines over one week. We find that the increase in SNAP benefits will increase fruit and vegetable affordability for participating households. However, households facing food prices greater than national average food prices may still face tradeoffs to purchase a balanced diet.

What is the availability, affordability, and quality of foods and beverages aligned with dietary guidance in Louisiana Supplemental Nutrition Assistance Program (SNAP) authorized stores?

Healthy food retail strategies are delivered by Cooperative Extension Services in Louisiana to improve public health among communities with lower income. To guide Cooperative Extension Services Programming, the aim of this study was to assess healthy food access among SNAP-authorized stores. This included comparing the availability, affordability, and quality of healthy foods sold in these stores by geography, ownership, and store type. Seventy-five Louisiana SNAP-authorized stores were selected for measurement. Between October 2019 and March 2020 (prior to the COVID-19 national emergency declaration), trained researchers used the Nutrition Environment Measures Survey in Stores (NEMS-S) to assess the availability, affordability, and quality of healthy versus less healthy foods and beverages in 42 SNAP-authorized stores, including: grocery (n = 12, 29%), convenience (n = 17, 41%), drug (n = 1, 2%), dollar (n = 11, 26%), and butcher/meat (n = 1, 2%). Multivariate analysis of variance (a priori, p < 0.05) determined if differences in total NEMS-S scores or subscores existed by geography (urban versus rural), ownership (corporate/chain versus independent), or store type. No urban/rural differences were identified. Corporate/chain SNAP-authorized stores scored higher on average than independent SNAP-authorized stores for the total NEMS-S score (17.2 versus 8.1; p = 0.009) and availability subscore (13.1 versus 6.1; p = 0.02). SNAP-authorized grocery stores scored higher than all other store types (total NEMS-S score 27.6), followed by SNAP-authorized dollar stores (total NEMS-S score 10.7), and SNAP-authorized convenience stores (total NEMS-S score 5) (p < 0.001). Louisiana Cooperative Extension Services should explore ways to scale healthy food retail strategies statewide with a specific emphasis on independent and smaller SNAP-authorized retailers.

Introducing the Microbes and Social Equity Working Group: Considering the Microbial Components of Social, Environmental, and Health Justice

Humans are inextricably linked to each other and our natural world, and microorganisms lie at the nexus of those interactions. Microorganisms form genetically flexible, taxonomically diverse, and biochemically rich communities, i.e., microbiomes that are integral to the health and development of macroorganisms, societies, and ecosystems. Yet engagement with beneficial microbiomes is dictated by access to public resources, such as nutritious food, clean water and air, safe shelter, social interactions, and effective medicine. In this way, microbiomes have sociopolitical contexts that must be considered. The Microbes and Social Equity (MSE) Working Group connects microbiology with social equity research, education, policy, and practice to understand the interplay of microorganisms, individuals, societies, and ecosystems. Here, we outline opportunities for integrating microbiology and social equity work through broadening education and training; diversifying research topics, methods, and perspectives; and advocating for evidence-based public policy that supports sustainable, equitable, and microbial wealth for all.

Supplemental Nutrition Assistance Program (SNAP)-Authorized Retailers' Perceived Costs to Use Behavioral Economic Strategies to Encourage Healthy Product Sales

SNAP-authorized retailers could use marketing-mix and choice-architecture (MMCA) strategies to improve SNAP purchases, but associated costs are unknown. Perceived cost and inconvenience to implement eight MMCA strategies were assessed among 29 U.S. retailers. Differences in perspective were explored (owners vs. managers, corporate vs. independent retailers, and by format). Place changes (e.g., added refrigeration) were perceived more costly and prompting (e.g., shelf labeling) less costly. Managers rated the perceived inconvenience to make proximity changes higher than owners (3.78 ± 1.4 and 2.33 ± 1.2, respectively) (p < .05). Results can inform strategies to improve the adoption and implementation of healthy food retail programs.
