The impact of a produce prescription programme on healthy food purchasing and diabetes-related health outcomes

A narrative review of clinic-community food provision interventions aimed at improving diabetes outcomes among food-insecure adults: examining the role of nutrition education

BACKGROUND

Food provision interventions (eg, produce/food prescriptions, food pharmacies, food voucher programs) that bridge clinic and community settings for improved nutritional health outcomes of at-risk patients have gained momentum. Little is known about the role of nutrition education and potential augmented impact on patient outcomes.

OBJECTIVE

To describe intervention designs and outcomes of direct food provision clinic-community programs aimed at improving diabetes-related outcomes (glycated hemoglobin [HbA1c] levels) among patients with type 2 diabetes (T2DM) or prediabetes and food insecurity, and to compare nutrition education components across interventions.

METHODS

The PubMed and Academic Search Complete databases were systematically searched for original peer-reviewed articles (published during 2011-2022) that described the impact of clinic-community food provision programs (ie, produce/food prescriptions, food pharmacies, and food voucher programs) onHbA1c values among adults diagnosed with T2DM or prediabetes and who screened positive for food insecurity or low income. Study designs, intervention approaches, program implementation, and intervention outcomes were described.

RESULTS

Ten studies representing 8 distinct programs were identified. There was a high degree of variation in the studies' design, implementation, and evaluation. Across the 8 programs, 6 included nutrition education; of these, 1 used a theoretical framework, and 3 incorporated goal setting. Nutrition education covered multiple topical contents, including general nutrition knowledge, fruit and vegetable consumption, and accessing resources (eg, enrolling in the Supplemental Nutrition Assistance Program). Furthermore, the education was delivered through various formats (from 1-on-1 to group-based sessions), educators (community health workers, registered dietitians, physicians), and durations (from a single session to biweekly). All programs with a nutrition education component reported reduced participant HbA1c, and 4 demonstrated an increase in fruit and vegetable purchases or improved dietary quality. The remaining 2 programs that did not include nutrition education yielded mixed results.

CONCLUSION

The majority of programs included a nutrition education component; however, there was a high degree of heterogeneity in terms of content, educator, and duration. Patients who participated in programs that included nutrition education had consistent reductions in HbA1c. These observational trends warrant further exploration to conclusively determine the impact of nutrition education on patient outcomes participating in clinic-community food provision programs.

Rationale and design of the KP ENRICH trial: A food is medicine intervention in low-income high-risk adults with diabetes within Kaiser Permanente

BACKGROUND

Food insecurity is associated with poor glycemic control and increased risk for diabetes-related complications. The clinical benefit of addressing these challenges through a medically supportive grocery prescription (GRx) program in patients with type 2 diabetes mellitus (T2D) remains unclear. We report the aims and design of a randomized clinical trial to evaluate the effectiveness of a 6-month GRx intervention on hemoglobin A1c (HbA1c) levels among low-income adults with T2D.

METHODS

The Kaiser Permanente Evaluating Nutritional Interventions in Food-Insecure High-Risk Adults (KP ENRICH) Study is a pragmatic randomized trial enrolling 1100 participants within Kaiser Permanente Northern California and Southern California, two integrated health care delivery systems serving >9 million members. Medicaid-insured adults with T2D and baseline HbA1c ≥7.5% will be randomized at a 1:1 ratio to either GRx, delivered as $100 per month for select items from among a curated list of healthful food groups in an online grocery ordering and home-delivery platform along with biweekly digital nutrition educational materials, or control, consisting of free membership and deliveries from the online grocery platform but without curated food groups or purchasing dollars. The primary outcome is 6-month change in HbA1c. Secondary outcomes include 12-month change in HbA1c, and 6- and 12-month change in medical resource utilization, food security, nutrition security, dietary habits, diabetes-related quality of life, and dietary self-efficacy.

CONCLUSIONS

The results of this large randomized clinical trial of GRx will help inform future policy and health system-based initiatives to improve food and nutrition security, disease management, and health equity among patients with T2D.

Advancing Lifestyle Medicine in New York City's Public Health Care System

Chronic diseases are the leading cause of death and disability in the United States, and much of this burden can be attributed to lifestyle and behavioral risk factors. Lifestyle medicine is an approach to preventing and treating lifestyle-related chronic disease using evidence-based lifestyle modification as a primary modality. NYC Health + Hospitals, the largest municipal public health care system in the United States, is a national pioneer in incorporating lifestyle medicine systemwide. In 2019, a pilot lifestyle medicine program was launched at NYC Health + Hospitals/Bellevue to improve cardiometabolic health in high-risk patients through intensive support for evidence-based lifestyle changes. Analyses of program data collected from January 29, 2019 to February 26, 2020 demonstrated feasibility, high demand for services, high patient satisfaction, and clinically and statistically significant improvements in cardiometabolic risk factors. This pilot is being expanded to 6 new NYC Health + Hospitals sites spanning all 5 NYC boroughs. As part of the expansion, many changes have been implemented to enhance the original pilot model, scale services effectively, and generate more interest and incentives in lifestyle medicine for staff and patients across the health care system, including a plant-based default meal program for inpatients. This narrative review describes the pilot model and outcomes, the expansion process, and lessons learned to serve as a guide for other health systems.

Perspective: Leveraging Electronic Health Record Data Within Food Is Medicine Program Evaluation: Considerations and Potential Paths Forward

Government, health care systems and payers, philanthropic entities, advocacy groups, nonprofit organizations, community groups, and for-profit companies are presently making the case for Food is Medicine (FIM) nutrition programs to become reimbursable within health care services. FIM researchers are working urgently to build evidence for FIM programs' cost-effectiveness by showing improvements in health outcomes and health care utilization. However, primary collection of this data is costly, difficult to implement, and burdensome to participants. Electronic health records (EHRs) offer a promising alternative to primary data collection because they provide already-collected information from existing clinical care. A few FIM studies have leveraged EHRs to demonstrate positive impacts on biomarkers or health care utilization, but many FIM studies run into insurmountable difficulties in their attempts to use EHRs. The authors of this commentary serve as evaluators and/or technical assistance providers with the United States Department of Agriculture's Gus Schumacher Nutrition Incentive Program National Training, Technical Assistance, Evaluation, and Information Center. They work closely with over 100 Gus Schumacher Nutrition Incentive Program Produce Prescription FIM projects, which, as of 2023, span 34 US states and territories. In this commentary, we describe recurring challenges related to using EHRs in FIM evaluation, particularly in relation to biomarkers and health care utilization. We also outline potential opportunities and reasonable expectations for what can be learned from EHR data and describe other (non-EHR) data sources to consider for evaluation of long-term health outcomes and health care utilization. Large integrated health systems may be best positioned to use their own data to examine outcomes of interest to the broader field.

A Systematic Review of Interventions That Address Food Insecurity for Persons With Prediabetes or Diabetes Using the RE-AIM Framework

PURPOSE

The purpose of this study is to systematically review interventions that address food insecurity for persons with prediabetes or type 2 diabetes using the RE-AIM (Reach, Effectiveness, Adoption, Implementation, Maintenance) framework.

METHODS

Six databases (OVIDMEDLINE, OVIDEMBASE, OVID APA PsycINFO, Web of Science, Cochrane Central Registry of Controlled Trials, and EBSCO CINAHL Complete) were searched through January 2023. Research team members independently performed screening of abstracts and full texts, data abstraction, and risk assessment.

RESULTS

In all, 3,139 unique citations were identified, and 20 studies met inclusion criteria. Interventions included medically tailored meals/groceries (n = 10) or produce prescriptions/vouchers (n = 10). Reach and effectiveness were the highest reported RE-AIM elements. Interventions reached a high-risk population via food banks, community-based outreach, and federally qualified health centers. A majority of participants identified as female, Black, or Hispanic/Latinx and were living below the federal poverty level. Most studies reported at least 1 diabetes outcome (ie, A1C, hypoglycemia, diabetes distress, diabetes self-management). Seventeen studies reported impact on A1C, with the majority reporting a decrease in A1C and 53% (9/17) of studies demonstrating a decrease over time. Self-management improved in 50% (3/6) of studies that evaluated this outcome. Self-efficacy improved in 40% (2/5) of studies, and improvements were seen in depressive symptoms/diabetes distress (4/7 studies) and quality of life (5/5 studies). Seven studies reported statistically significant improvements in food insecurity.

CONCLUSION

Food insecurity has been associated with higher risks and adverse clinical outcomes in adults with diabetes. Implementing interventions that address food insecurity among adults with or at risk for diabetes can enhance food security and clinically important diabetes-related outcomes. Additional research dedicated to the sustainability of interventions is needed.

Clients' experiences and satisfaction with produce prescription programs in California: a qualitative evaluation to inform person-centered and respectful program models

Background

Produce prescription programs have strong potential to improve food security, fruit and vegetable consumption, and health across the life course. Understanding clients' experiences and satisfaction with produce prescription programs is critical for evaluating the person-centeredness and quality of these programs. The objectives of this study were to (1) describe client experiences and satisfaction with produce prescription programs, with an emphasis on the extent to which they felt they were treated with respect and dignity, and (2) identify recommendations for improving client experiences.

Methods

We conducted four focus group discussions with clients of produce prescription programs in two Federally Qualified Health Centers in California. We used a modified framework analysis approach and organized participants' experiences with programs into themes.

Results

Three themes captured participants' program experiences. First, respectful produce prescription programming encompassed interactions with individuals delivering the programs that felt respectful (e.g., program staff showing they cared about participants' health and offering timely assistance with financial incentives) and disrespectful (e.g., not receiving prompt responses to questions about incentives), as well as aspects of program design perceived to be respectful (e.g., provision of gift cards as financial incentives, which offered privacy when purchasing produce). Second, having autonomy to use gift cards to choose their preferred fresh fruits and vegetables was viewed as a positive experience, though participants desired greater autonomy to shop at stores other than the program designated stores. Third, participants frequently discussed program usability, with some reporting that joining the programs and using the cards was easy, and others describing difficulties activating cards and using them at stores due to cashiers' lack of awareness of the programs. Overall, participants were highly satisfied with the programs. To improve client experiences, they recommended increasing privacy (e.g., by educating cashiers on the programs so that clients do not need to explain in public what the card is for) and autonomy (e.g., allowing cards to be used at other chain or local stores).

Discussion

Our findings inform efforts to make produce prescription programs more person-centered and respectful, which in turn may increase program demand, engagement, and impact.

A Clinical-Community Partnership to Address Food Insecurity and Reduce Emergency Department Utilization Among Medicaid-Insured Patients in North Carolina

CONTEXT

Socioeconomic risk factors have the greatest impact on overall health trajectory. Patients with Medicaid insurance are more likely to experience food insecurity, in addition to poor health and increased health care utilization. Targeted food and produce prescription programs can reduce food insecurity, but sustainable implementation is challenging and evidence demonstrating the impact on clinical utilization outcomes is lacking.

PROGRAM

In 2021, a cross-sector collaboration between Mecklenburg County Public Health, Reinvestment Partners, and Atrium Health initiated a food prescription program in urban North Carolina. A low-cost mass text message campaign was used to identify and enroll Medicaid-insured patients with a history of emergency department (ED) utilization.

METHODS

A nonrandomized before/after evaluation design was used with a 12-month data collection window (6 months before/after program enrollment) for 711 patients enrolled between June 2021 and 2022. Changes in the odds of nonadmission ED utilization were modeled using logistic regression, adjusting for race/ethnicity, gender, age, comorbidity, and dose, along with interaction by comorbidity.

RESULTS

A majority of the sample was non-Hispanic Black (61%; n = 436), female (90%; n = 643), with "none to mild" chronic disease comorbidity (81%; n = 573). The unadjusted and adjusted odds of nonadmission ED utilization significantly reduced between time periods, along with significant interaction by comorbidity. Among the subsamples, patients with "none to mild" comorbidity showed 34% reduction in odds of nonadmission ED utilization (OR = 0.64; 95% CI, 0.47-0.86).

DISCUSSION

Food prescription programming targeting Medicaid-insured patients may reduce ED utilization, particularly among those without severe comorbidity. Retrospective data collection and sample homogeneity reduced the quality of evidence, but results offer a pragmatic example that can be replicated for further study. Additional research is needed to strengthen the body of evidence and support cross-sector investment in food and produce prescription programming.

Healthcare-based food assistance programmes in the United States: a scoping review and typology

This scoping review aimed to identify the breadth of healthcare-based food assistance programmes in the United States and organize them into a typology of programmes to provide implementation guidance to aspiring food assistance programmers in healthcare settings. We searched PubMed, Cochrane, and CINAHL databases for peer-reviewed articles published between 1 January 2010 and 31 December 2021, and mined reference lists. We used content analysis to extract programmatic details from each intervention and to qualitatively analyse intervention components to develop a typology for healthcare institutions in the United States. Eligible articles included descriptions of patient populations served and programmatic details. Articles were not required to include formal evaluations for inclusion in this scoping review. Our search resulted in 8706 abstracts, which yielded forty-three articles from thirty-five interventions. We identified three distinct programme types: direct food provision, referral, and voucher programmes. Programme type was influenced by programme goals, logistical considerations, such as staffing, food storage or refrigeration space, and existence of willing partner CBOs. Food provision programmes (n 13) were frequently permanent and leveraged partnerships with community-based organisations (CBOs) that provide food. Referral programmes (n 8) connected patients to CBOs for federal or local food assistance enrollment. Voucher programmes (n 14) prioritised provision of fruits and vegetables (n 10) and relied on a variety of clinic staff to refer patients to months-long programmes. Healthcare-based implementers can use this typology to design and maintain programmes that align with the needs of their sites and patient populations.

Design and protocol of a clinic-based comparative effectiveness randomized controlled trial to determine the feasibility and effectiveness of food prescription program strategies in at-risk pediatric populations

BACKGROUND

Produce prescription programs are gaining traction in the U.S.; however, data on the impact of such approaches in pediatric populations are limited. The purpose of our clinic-based comparative effectiveness randomized controlled trial (CE RCT) is to evaluate the preliminary effectiveness of two produce prescription strategies (at-home delivery and grocery store vouchers) implemented by the Brighter Bites non-profit organization in improving obesity-related health outcomes and dietary behaviors among low-income 5-12-year-olds in Houston, Texas. This paper presents the study design, intervention components, and the study measures.

METHODS

Participants (n = 150) are being recruited from two pediatric clinics in Houston, Texas. Child eligibility criteria are aged 5-12 years, Medicaid recipients, body-mass index (BMI) percentile ≥85 and living within 10 miles of a Brighter Bites distribution site. Following consent and baseline measures, children are randomized into one of three arms: (1) Bi-weekly $25 vouchers redeemable for produce at stores (n = 50), (2) Bi-weekly produce delivery to participants' homes through DoorDash (n = 50), and (3) wait-list usual care controls (n = 50). Intervention participants also receive Brighter Bites nutrition education materials. Main child outcome measures are BMI z-scores, blood pressure, hemoglobin A1c, liver panels, and lipid panels. Other outcomes including household food insecurity, child diet quality, and home nutrition environment will be collected through parent surveys. Outcome measures are collected at baseline and post-intervention. Process evaluation will measure program dosage, reach, acceptability, and feasibility.

CONCLUSIONS

Our paper presents the design and next steps to ensure the successful implementation of a produce prescription program in a pediatric clinic setting.

Community-based fruit and vegetable prescription programs: a scoping review

Identify and categorise different models of community-based fruit and vegetable prescription programs, to determine variation in terms of methodology, target population characteristics, and outcomes measured. Applying the scoping review methodology, ten electronic databases were utilised to identify community-based fruit and vegetable incentive programs. Results were evaluated by two independent reviewers, using Covidence software. All full-text reviews were completed and documented using the PRISMA-ScR guidelines. Search results were stored and reviewed within the Covidence software. Thirty full-text articles were utilised from the 40 206 identified in the search. Target populations were predominantly female, non-white, and low-income. Considerable heterogeneity was found in both study design and quality. Fruit and vegetable vouchers were utilised in 63 % (n 19) of the studies. Prescriptions were primarily provided by community health centres (47 %; n 14) or NGOs (307 %; n 9) and could be redeemed at farmers' markets (40 %; n 12) or grocery stores (27 %; n 8). When measured, diet quality significantly improved in 94 % (n 16), health outcomes significantly improved in 83 % (n 10), and food security status improved in 82 % (n 10) of studies. Providing financial incentives to offset the cost of fresh fruits and vegetables can increase consumption, improve health outcomes, and improve food security status. The majority of studies showed significant improvements in at least one outcome, demonstrating the effectiveness of community-based fruit and vegetable prescription programs. However, the diversity of measurement techniques and heterogeneity of design, dosage, and duration impeded meaningful comparisons. Further well-designed studies are warranted to compare the magnitude of effects among different program methodologies.

The Impact of Providing Material Benefits to Improve Access to Food on Clinical Parameters, Dietary Intake, and Household Food Insecurity in People with Diabetes: A Systematic Review with Narrative Synthesis

The high cost of healthy foods makes maintaining a healthy dietary pattern challenging, particularly among people with diabetes who are experiencing food insecurity. The objectives of this study were to: 1) review evidence on the impact of providing material benefits (e.g., food coupons/vouchers, free food, or financial subsidies/incentives) to improve access to food on clinical parameters, dietary intake, and household food insecurity in people with diabetes, and 2) review relevant economic evidence. Six databases were searched from inception to March 2023 for longitudinal studies with quantitative outcomes. Twenty-one studies were included in the primary review and 2 in the economic analysis. Risk of bias was high in 20 studies and moderate in 1 study. The number of randomized controlled trials and nonrandomized studies reporting statistically significant improvement, alongside Grading of Recommendations Assessment, Development, and Evaluation (GRADE) certainty of the evidence was: HbA1c: 1/6 and 4/12 (very low), systolic blood pressure: 0/3 and 1/8 (very low), diastolic blood pressure: 0/3 and 1/7 (very low), BMI: 0/5 and 2/8 (very low), body weight: 0/0 and 1/3 (very low), hypoglycemia: 1/2 and 1/2 (very low), daily intake of fruits and vegetables: 1/1 and 1/3 (very low), daily intake of whole grains: 0/0 and 0/2 (very low), overall diet quality: 2/2 and 1/1 (low), and household food insecurity: 2/3 and 0/0 (very low). The 2 studies included in the economic analysis showed no difference in Medicare spending from Supplemental Nutrition Assistance Program participation and cost-savings from medically tailored meals in an economic simulation. Overall, providing material benefits to improve access to food for people with diabetes may improve household food insecurity, fruit and vegetable intake, and overall diet quality, but effects on clinical parameters and whole grain intake are unclear. The certainty of evidence was very low to low by GRADE. PROSPERO (CRD42021212951).

A Systematic Literature Review of Nutrition Interventions Implemented to Address Food Insecurity as a Social Determinant of Health

BACKGROUND

Policy initiatives have provided funding for non-acute nutrition interventions to address food insecurity as a social determinant of health, but more research is needed to understand the outcomes of these initiatives in order to determine the areas of highest impact. Therefore, the purpose of this systematic review was to evaluate the outcomes that were assessed in three nutrition interventions (produce prescription programs, medically tailored meals, and community supported agriculture) that aim to address food insecurity as a social determinant of health, and this was undertaken in order to identify future areas of study that can heighten impact.

METHODS

This systematic review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) criteria. A list of search terms and keywords were compiled by the research team. A Boolean search was conducted from 1 January 2000 to 1 January 2023 in the PubMed advanced search database.

RESULTS

A total of 1015 articles were initially pulled from the PubMed database, and, after a screening process, 21 articles were included in our review. Nineteen of the articles focused on adult populations or families and two focused on children. The main outcomes assessed were changes in self-reported dietary intake, while a few of the articles addressed feasibility and cost-related outcomes.

CONCLUSIONS

More research is needed to assess whether nutritional interventions to address food insecurity as a social determinant of health are feasible and more cost effective in the long term. Additionally, more work should be conducted in pediatric populations, which could have a robust return on investment in terms of both healthcare utilization and healthcare expenditure.

Patients' experiences with a community fruit and vegetable box program prescribed by their health provider

BACKGROUND

Food insecurity is "the state of being without reliable access to a sufficient quantity of affordable, nutritious food". Observational studies have associated food insecurity with many negative health effects including the development and exacerbations of chronic diseases, higher health care use and increased mortality. Health care providers prescribing food is a growing area of interest and research, however it is not known how patients feel about receiving fruit and vegetable prescriptions (FVRx) from their health provider versus other means of food provision. This pilot study was conducted to explore the experiences and opinions of Canadian adults with food insecurity who were recipients of a FVRx box program prescribed by their health provider.

METHODS

Potential participants were recruited to 3 focus groups using flyers included in their monthly food box. Questions were kept open to encourage participation of all group members. The focus groups were audiotaped, transcribed verbatim, and analyzed by the research team using descriptive qualitative research methodology.

RESULTS

Participants described shame and frustration trying to obtain enough food through local food banks. In comparison, they perceived their team dietitian, family physician or addictions physician as directly helping them with their health by prescribing food. The boxed fruit and vegetables were prepared in many ways and often shared to reduce waste and to reduce the food insecurity of extended family members. Positive effects of the FVRx on physical and mental health were reported. Participants believed that follow up with their health provider helped support them and their behavioural changes towards better nutrition. Limitations of the program included lack of choice, non-flexible pick-up times and the program being limited to 6 months. Being able to choose their own fruit and vegetables, instead of receiving a set box, was suggested by most to help meal planning and to increase autonomy.

CONCLUSIONS

Health providers prescribing FVRx boxes to adult patients with food insecurity was positively received in this study. Evaluation of similar programs in other regions in Canada and internationally, and comparison of food prescriptions to basic income guarantee programs is recommended.

The Effect of Food is Medicine Interventions on Diabetes-related Health Outcomes Among Low-income and Food-insecure Individuals: A Systematic Review and Meta-analysis

OBJECTIVE

In this study, we aim to review the current evidence of Food is Medicine interventions on diabetes outcomes among low-income or food-insecure individuals.

METHODS

Seven databases were searched from January 1, 2000 to October 26, 2021 for full-text articles written in English. The studies included experimental studies of any duration and design which addressed the effect of Food is Medicine interventions on fruit and vegetable (F&V) intake and glycated hemoglobin (A1C) levels among low-income or food-insecure populations with prediabetes or diabetes of any age group. Only direction of effect of interventions on F&V intake were ascertained due to high variability in outcome measurement. A1C results were pooled using generic inverse variance with a fixed-effects model. Heterogeneity was assessed using Cochran's Q and quantified by I².

RESULTS

Sixteen studies were included. Five of the 8 studies reported a significant increase in F&V intake. Seven of the 14 studies reported a significant decrease in A1C levels. A meta-analysis of 5 randomized controlled trials (n=843) resulted in clinically meaningful reductions in A1C compared with control (mean difference, -0.47%; 95% confidence interval, -0.66 to -0.29, I²=88%, p<0.0001). Half (n=8) of the studies have a high risk of bias due to missing data, detection bias, and confounding.

CONCLUSIONS

Food is Medicine interventions are effective in increasing F&V intake and reducing A1C levels of the target population. More randomized controlled studies are needed to validate the results.

Changes to household food shopping practices during the COVID-19 restrictions: Evidence from the East of England

Measures to control the spread of COVID-19 have changed the way we shop for food and interact with food environments. This qualitative study explored food shopping practices in the East of England, a large diverse region including coastal, urban and rural settings. In 2020/2021 we interviewed 38 people living in the region and 27 professionals and volunteers providing local support around dietary health. Participants reported disruption to supermarket shopping routines; moving to online shopping; and increased reliance on local stores. COVID-19 has impacted disproportionately upon lower-income households and neighbourhoods. The longer-term implications for dietary health inequalities must be investigated.

A Produce Prescription Program in Eastern North Carolina Results in Increased Voucher Redemption Rates and Increased Fruit and Vegetable Intake among Participants

Few produce prescription programs have taken place in rural areas, in the context of existing public health programs. Thus, the purpose of this mixed-methods study was to examine voucher redemption rates, change in fruit and vegetable intake, and suggestions for improvement among participants enrolled in a produce prescription program occurring in existing public health programs throughout rural eastern North Carolina. We examined voucher redemption rates and conducted pre- (n = 125) and post-intervention surveys assessing fruit and vegetable intake. t-tests were used to examine changes in intake pre- versus post-intervention among 50 participants. Participants (n = 32) also completed a semi-structured, telephone interview. Qualitative data were thematically analyzed to determine potential improvements. The overall voucher redemption rate was 52%. There was a 0.29 (standard deviation = 0.91, p = 0.031) cup increase in self-reported fruit intake comparing post- to pre-intervention data. Qualitative analyses indicated that participants enjoyed the financial benefits of the program and wanted it to continue. The produce prescription program was successful in increasing self-reported fruit intake among participants. More research is needed to determine if changes in intake persist when measured objectively, and on best methods for the program’s financial sustainability.

Effects of a Fruit and Vegetable Prescription Program With Expanded Education for Low-Income Adults

Fruit and Vegetable Prescription (FVRx) Programs combine produce prescriptions and nutrition education to reduce fruit and vegetable consumption barriers and promote health among low-income patient populations. This study examined whether a multi-level FVRx intervention model with intensive education improves dietary behaviors, food security, and health outcomes over single-level interventions alone. A 6-month nonrandomized, parallel, controlled trial was conducted with one intervention, FVRx (n = 31) and two comparison groups, Ad hoc Nutrition Education (n = 13) and Control (n = 16). The FVRx group received produce prescriptions (US$1/day/household member) redeemable at a farmer's market, two SNAP-Ed programs, one financial literacy program, and monthly health screenings. The Nutrition Education (NE) group participated in one SNAP-Ed program, and the Control group received safety-net clinic care only. Surveys assessed dietary intake, food security, food purchasing practices, and financial and food resource management. Pre-post clinical biomarkers (blood lipid and hemoglobin A1c) and monthly biometrics (anthropometrics and blood pressure) were measured. Descriptive analysis and one-way analysis of variance (ANOVA) were conducted. Compared with comparison groups, FVRx participants significantly increased the frequency of consuming dark green vegetables, FVRx (0.36 ± 0.72); NE (0.14 ± 0.33); Control (-0.09 ± 0.19) cups/day (p < .05). FVRx participants significantly improved multiple healthful food purchasing practices, and the ability to afford more utilities (FVRx (33%); NE (0%); Control (10%); p < .05). Limited changes were observed in food security and clinical biomarker outcomes between groups. Combining expanded nutrition and financial literacy education with produce prescriptions improves low-income adults' financial and food resources, preference, knowledge, purchase, and consumption of locally grown vegetables over single-level interventions.

The nutrition transition to a stage of high obesity and noncommunicable disease prevalence dominated by ultra-processed foods is not inevitable

The Nutrition Transition model is presented with the nature and pace of change in key stages varying by location and subpopulations. At present, all high-income and many low- and middle-income countries are in a stage of the transition where nutrition-related noncommunicable diseases including obesity, type 2 diabetes, and hypertension are dominating adult morbidity and mortality and are very high or growing rapidly in prevalence. Some countries still have key subpopulations facing hunger and undernutrition defined by stunting or extreme thinness among adults. We call these double burden of malnutrition countries. All low- and middle-income countries face rapid growth in consumption of ultra-processed food and beverages, but it is not inevitable that these countries will reach the same high levels of consumption seen in high-income countries, with all the negative impacts of this diet on health. With great political and civil society commitment to adoption of policies shown in other countries to have improved dietary choices and social norms around foods, we can arrest and even reverse the rapid shift to diets dominated by a stage of high ultra-processed food intake and increasing prevalence of nutrition-related noncommunicable diseases.

A Case for Using Electronic Health Record Data in the Evaluation of Produce Prescription Programs

Produce prescription programs within clinical care settings can address food insecurity by offering financial incentives through "prescriptions" for fruits and vegetables to eligible patients. The electronic health record (EHR) holds potential as a strategy to examine the relationship between these projects and participant outcomes, but no studies address EHR extraction for programmatic evaluations. We interviewed representatives of 9 grantees of the U.S. Department of Agriculture's Gus Schumacher Nutrition Incentive Grant Program's Produce Prescription Projects (GusNIP PPR) to understand their experiences with and capacity for utilizing EHR for evaluation. Five grantees planned to use EHR data, with 3 main strategies: reporting aggregate data from health clinics, contracting with external/third party evaluators, and accessing individual-level data. However, utilizing EHRs was prohibitive for others due to insufficient knowledge, training and/or staff capacity; lack of familiarity with the Institutional Review Board process; or was inappropriate for select target populations. Policy support for produce prescription programs requires a robust evidence base, deep knowledge of best practices, and an understanding of expected health outcomes. These insights can be most efficiently and meaningfully achieved with EHR data, which will require increased financial support and technical assistance for project operators.

Promoting Healthy Food Access and Nutrition in Primary Care: A Systematic Scoping Review of Food Prescription Programs

Objective

To conduct a scoping review to synthesize evidence on food prescription programs.

Data Source

A systematic search of PubMed, CINAHL, Web of Science, Embase, and the Cochrane Library was conducted using key words related to setting, interventions, and outcomes.

Study Inclusion and Exclusion Criteria

Publications were eligible if they reported food prescription administered by a health care practitioner (HCP) with the explicit aim of improving healthy food access and consumption, food security (FS), or health.

Data Extraction

A data charting form was used to extract relevant details on intervention characteristics, study methodology, and key findings.

Data Synthesis

Study and intervention characteristics were summarized. We undertook a thematic analysis to identify and report on themes. A critical appraisal of study quality was conducted using the Mixed Methods Appraisal Tool (MMAT).

Results

A total of 6145 abstracts were screened and 23 manuscripts were included in the review. Food prescriptions may improve fruit and vegetable consumption and reduce food insecurity (FI). Evidence for impacts on diet-related health outcomes is limited and mixed. The overall quality of included studies was weak. Addressing barriers such as stigma, transportation, and poor nutrition literacy may increase utilization of food prescriptions.

Conclusion

Food prescriptions are a promising health care intervention. There is a need for rigorous studies that incorporate larger sample sizes, control groups, and validated assessments of dietary intake, food security, and health.
