Effect of an Intensive Food-as-Medicine Program on Health and Health Care Use: A Randomized Clinical Trial

Can Prevention Save Money?

This JAMA Forum discusses some key considerations for addressing the question of whether and when prevention interventions are worth the cost.

Medicaid Nutrition Supports Associated With Reductions In Hospitalizations And ED Visits In Massachusetts, 2020-23

The Massachusetts Medicaid and Children's Health Insurance Program launched the Flexible Services Program to address food insecurity through partnerships with social service organizations under its Section 1115 demonstration waiver. We evaluated the effects of Flexible Services Program nutritional services (or Food Is Medicine programs) on health care use and costs during the first three-year program cycle (January 2020-March 2023). Our analyses pooled data on 20,403 Flexible Services Program participants from seventeen accountable care organizations. In propensity score-weighted analyses, program participation was associated with a 23 percent reduction in hospitalizations and a 13 percent reduction in emergency department visits compared with the number of hospitalizations and visits for 2,108 eligible nonparticipants. Modestly lower health care costs for Flexible Services Program participants were not statistically significant. Health care costs were $1,721 lower among participants after the COVID-19 emergency (2022-23) and $2,502 lower among adults with more than ninety days of enrollment during all study years (2020-23). These findings are important for Medicaid policy nationwide as other state Medicaid programs pursue similar Section 1115 demonstrations.

Health-Related Social Needs Intervention for Adolescents and Young Adults With Type 2 Diabetes and Their Caregivers: An Exploratory Study Using Human-Centered Design

Youth-onset type 2 diabetes (T2D) is increasingly common and projected to impact over 200,000 adolescents and young adults by 2060. Youth with T2D frequently experience health-related social needs (HRSN) that increase their risk for poor outcomes. Using human-centered design methodology, we explored how best to address HRSN in pediatric endocrinology clinics. We conducted two parallel, six-session group meetings with youth (n = 4) and caregivers of youth (n = 6), as well as individual interviews with 12 pediatric endocrinology clinicians. An inductive thematic data analysis approach was used. Participants described that HRSN are pervasive for youth with T2D and are especially impactful after diagnosis. Participants thought that addressing HRSN in healthcare settings was important but emphasized that interventions need to be affirming and provide tangible, relevant resources. Engagement with community health workers trained around diabetes management is needed, as is structural change to disrupt health disparities. Future research and clinical transformation are discussed.

Feasibility of self-investment in a medically tailored meals program by a large health enterprise: Cleveland Clinic experience

Background: Medically tailored meals (MTMs) are personalized meals designed to meet the therapeutic needs of patients with chronic diseases. Most MTM programs rely on philanthropic support, and the optimal parameters for these programs are not well-defined. Aim: To assess the feasibility of an MTM program developed by a major healthcare institution using internal investments and an online platform for meal ordering. Methods: Single-arm prospective cohort feasibility MTM project implemented between August 2021 and June 2022. Each participant received 14 frozen meals per week over 3 months via a courier system. Participants answered several questionnaires and healthcare utilization was abstracted from electronic medical records up to 6 months post-intervention. Results: Sixty participants were enrolled. Emergency department (ED) visits and inpatient days significantly decreased in the 180 days post-intervention compared to the 180 days pre-intervention (ED visits: 1.2 vs 1.7, P = 0.005; inpatient days: 3.2 vs 5.1, P = 0.02). Participants saved an average of $12,046 in healthcare costs. Despite challenges with implementation, including upfront costs and sustainability, client and service outcomes were highly favorable. Patients were overwhelmingly satisfied with the program, although there was no quantitative improvement in global mental health (GMH) or global physical health (GPH) scores. Conclusion: MTM programs run by healthcare institutions can enhance patient satisfaction, reduce hospital visits, and lower healthcare costs, particularly for vulnerable populations. Providing healthy, frozen meals over an extended period is feasible, though it requires significant initial investment. Large healthcare institutions should consider implementing such programs to prioritize primary prevention in the US healthcare system.

Development of a statewide network hub for screening, referral, and enrollment into food as medicine programs across Kentucky

Widespread recognition of food as medicine interventions' role in reducing food insecurity and improving health outcomes has recently emerged. Several states have released In Lieu of Services, state-approved alternative services that may be offered by managed care organizations in place of covered benefits, or 1,115 Medicaid waivers, which may allow for expanded nutrition services to reduce food insecurity and improve health outcomes. However, there are significant gaps in understanding how to create a statewide system for delivering "healthcare by food" interventions. The University of Kentucky Food as Health Alliance first piloted the development of a statewide hub facilitating referral to, enrollment in, and evaluation of food as medicine programs across two healthcare providers (one urban and one rural). We then used a quasi experimental study design to examine effects on systolic and diastolic blood pressure in a target population of Medicaid eligible individuals aged 18-64 with high blood pressure and/or type 2 diabetes in rural and urban areas. Participant allocation was based on geographic location for each program arm with no control group. This feasibility case study aims to: (1) outline the development of a referral system between healthcare and food as medicine providers; (2) describe gaps in referral and enrollment; (3) summarize lessons learned from a statewide network as a blueprint for other states; and (4) present clinical outcomes across three food as medicine programs. Ninety-two referrals were received from UK HealthCare with 21 enrolled in medically tailored meals and 28 enrolled in a grocery prescription (53% enrollment rate). Thirty-two referrals were received from Appalachian Regional Healthcare with 26 enrolled in meal kits (81% enrollment rate). On average, the reduction in systolic blood pressure was 9.67 mmHg among medically tailored meals participants and 6.89 mmHg among grocery prescription participants. Creating a statewide system to address food insecurity and clinical outcomes requires key support from a host of stakeholders. Policy steps moving forward need to consider funding and infrastructure for screening, referral, enrollment and engagement hubs for improved health outcomes.

Impact of Dietitian-Delivered Motivational Interviewing Within a Food is Medicine Intervention Targeting Adults Living With and Beyond Cancer

Food is medicine (FIM) interventions are a strategy for preventing and managing chronic disease via diet. These interventions often combine the provision of food with access to behavior change support (e.g., from registered dietitians (RDs)), though the ideal approach for the latter is not fully elucidated. The objective of this study is to evaluate integrated motivational interviewing (MI) from an RD (RDMI) on outcomes among adults living with and beyond cancer (LWBC) with overweight and obesity enrolled in a FIM intervention (Clinicaltrials.gov: NCT03489213 (02/09/2018)). Specifically, RDMI with autonomy in the mode of delivery (i.e., phone, email, text, video) and dose (frequency) was offered within a 6-month intensive FIM intervention followed by a 6-month step-down maintenance phase. Dose and engagement with RDMI were measured. There were 52 and 33 participants who requested RDMI during the intensive and maintenance phases, respectively. Completion of ≥ 1 RDMI telephonic encounter significantly predicted weight loss post-intervention (R2 = 0.07, p = 0.03); there were no differences in dose, engagement, or weight loss based on the mode of delivery. The dose during the intensive intervention was moderately and significantly correlated with weight loss post-intervention and maintenance (r = 0.43, p < 0.01; r = 0.33, p = 0.02, respectively); there was a weak correlation for engagement at the same follow-up points (r = 0.28 and r = 0.15). In conclusion, higher doses of RDMI improved weight loss for adults LWBC with overweight or obesity. Careful consideration of the implementation of MI from providers, including RDs, in the context of cancer-focused FIM interventions should be further examined.

The role of government assistance, housing, and employment on postpartum maternal health across income and race: a mixed methods study

BACKGROUND

Stressful large-scale events, such as the COVID-19 pandemic and natural disasters, impact birthing individuals' postpartum experiences and their mental health. Resultant changes in government assistance, housing, and employment may further exacerbate these impacts, with differences experienced by varying income levels and races. This study aimed to examine maternal depression and anxiety in postpartum individuals by income and race during a stressful large-scale event, and the mediating role of government assistance, housing, and employment.

METHODS

An explanatory sequential mixed methods study was conducted (QUANT + QUAL). For aim 1 (quantitative), birthing individuals who delivered during peak pandemic (June 2020 - September 2021) completed questionnaires related to their perinatal experiences and mental health. Macrosystem factors (government assistance, housing, and employment changes) were assessed using the Psychosocial Recommended Measures. The Edinburgh Postnatal Depression Scale (EPDS) and the Generalized Anxiety Disorder-7 (GAD7) assessed depression and anxiety, respectively. Serial linear regression models assessed the relationship between race and income with mental health and macrosystem factors. For aim 2 (qualitative), 40 individuals from the quantitative study balanced by income (low vs. high income) and race (Black vs. White) completed one-on-one semi-structured interviews which were analyzed using thematic analysis.

RESULTS

Amongst 1582 birthing individuals, Black individuals had a significantly higher EPDS score compared to White counterparts. Not receiving government assistance, unstable housing, and experiencing various employment changes were all related to worse mental health during stressful large-scale events. In semi-structured interviews, low-income individuals discussed that government assistance helped alleviate a financial and mental burden. Low- and high-income individuals reported varying job changes that impacted their mental health (low-income: job loss, high-income: increased hours).

CONCLUSIONS

This research spotlights the negative impact of large-scale events most affected both Black and low-income individuals' postpartum mental health, and the role of government assistance, stable housing, and secure employment in helping to alleviate these disparities between income levels.

Health outcomes reported by healthcare providers and clients of a community-based medically tailored meal program

BACKGROUND

Medically tailored meal (MTM) programs provide home-delivered meals to people living with serious illness and poor nutritional status. Client outcome studies have found evidence of decreased healthcare utilization and cost savings associated with MTM program participation, and inconclusive evidence of change in health measures. The purpose of this study was to use a novel observational framework to describe the client profile and change in health outcomes using routinely collected health and program data from a community-based MTM program at MANNA (Philadelphia, PA).

METHODS

Clients reported their self-rated health and experiences of food insecurity and malnutrition. Healthcare providers reported clients' body mass index, systolic blood pressure, and hemoglobin A1C. These health outcomes, measured at program intake and 3-6 months later, were linked with administrative data for 1,959 clients who completed at least two months of MTM services in 2020, 2021, and 2022.

RESULTS

Clients exhibited substantial heterogeneity in demographics and health status at intake. Self-reported malnutrition risk decreased significantly over program duration (p < .001). Nearly one-third of clients with poor health reported improvement over time. Over 60% of clients with obesity experienced stable BMI. Clients with hypertension experienced significant improvements in systolic blood pressure (p < .001). Clients with diabetes and available data (n = 45) demonstrated significant reduction in hemoglobin A1C (p = .005).

CONCLUSION

We found evidence that participation in MANNA's MTM program was associated with favorable health outcomes for clients with serious illness and nutritional risk. Community-based organizations can maximize the completeness of their data by focusing on routinely collected internal data like validated health screeners and surveys.

Addressing diabetes by elevating access to nutrition (ADELANTE) - A multi-level approach for improving household food insecurity and glycemic control among Latinos with diabetes: A randomized controlled trial

BACKGROUND

Latinx adults are disproportionately impacted by the interrelated challenges of food insecurity and nutrition sensitive chronic diseases. Food and nutrition insecurity can exacerbate the development and progression of chronic diseases, such as diabetes. Sustainable, effective interventions aimed at improving food insecurity and diabetes management for Latinx populations are needed.

METHODS

This hybrid type 1 trial evaluates the effectiveness of a multi-level intervention that includes a medically supportive food and behavioral lifestyle program on the primary outcome of Hemoglobin A1c (HbA1c) at 6 months. Latinx adults (n = 355) with type 2 diabetes (HbA1c of 6.0-12.0 %), overweight/obesity (BMI > 25 kg/m2), and self-reported risk of food insecurity will be randomized 1:1 to intervention (12 weekly deliveries of vegetables, fruits, and whole-grain foods + culturally-modified behavioral lifestyle program) versus control (food deliveries after a 6-month delay). Outcome asessments will occur at 0, 6 and 12 months, and include HbA1c, dietary intake, psychosocial health outcomes, and diabetes-related stressors. In addition, food insecurity and the impact of the intervention on up to two household members will be measured. Qualitative interviews with patients, healthcare providers, and community partners will be conducted in accordance with Reach, Effectivenes, Adoption, Implementation, and Maintenence (RE-AIM) framework to identify barriers and best practices for future dissemination.

CONCLUSIONS

The ADELANTE trial will provide novel insight to the effectiveness of a multi-level intervention on diabetes-related outcomes in Latinx adults. The mixed-method approach will also identity the reach of this 'Food is Medicine' intervention on additional household members to inform diabetes prevention efforts.

Connecting precision nutrition with the Food is Medicine approach

Two initiatives are reshaping how we can approach and address the persistent and widely prevalent challenge of malnutrition, the leading global risk factor for morbidity and mortality. First is the focus on precision nutrition to identify inter- and intra-individual variation in our responses to diet, and its determinants. Second is the Food is Medicine (FIM) approach, an umbrella term for programs and services that link nutrition and health through the provision of food (e.g., tailored meals, produce prescriptions) and access to healthcare services. This article outlines how interventions and programs using FIM can synergize with precision nutrition approaches to make individual- or population-level tailored nutrition accessible and affordable, help to reduce the risk of metabolic diseases, and improve quality of life.

Estimating the impact of addressing food needs on diabetes outcomes

Objective

To estimate the association between food needs and diabetes outcomes.

Research design and methods

Longitudinal cohort study, using a target trial emulation approach. 96,792 adults with type 2 diabetes mellitus who underwent food need assessment in a network of community-based health centers were followed up to 36 months after initial assessment. We used targeted minimum loss estimation to estimate the association between not experiencing food needs, compared with experiencing food needs, and hemoglobin a1c (HbA1c), systolic and diastolic blood pressure (SBP and DBP), and LDL cholesterol. The study period was June 24th, 2016 to April 30th, 2023.

Results

We estimated that not experiencing food needs, compared with experiencing food needs, would be associated with 0.12 percentage points lower (95% Confidence Interval [CI] -0.16% to -0.09%, p = < 0.0001) mean HbA1c at 12 months. We further estimated that not experiencing food needs would be associated with a 12-month SBP that was 0.67 mm Hg lower (95%CI -0.97 to -0.38 mm Hg, p < .0001), DBP 0.21 mm Hg lower (95%CI -0.38 to -0.04 mm Hg, p = .01). There was no association with lower LDL cholesterol. Results were similar at other timepoints, with associations for HbA1c, SBP, and DBP of similar magnitude, and no difference in LDL cholesterol.

Conclusions

We estimated that not experiencing food needs may be associated with modestly better diabetes outcomes. These findings support testing interventions that address food needs as part of their mechanism of action.

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.

A theoretical explanation for how a nutrition counseling and medically tailored meal delivery program benefitted participants living with lung cancer

PURPOSE

The purpose of this study was to assess participants' perceptions and experiences while participating in a Food is Medicine medically tailored meal plus intensive nutrition counseling intervention to create a theoretical explanation about how the intervention worked.

METHODS

This interpretive qualitative study included the use of semi-structured interviews with active participants in a randomized controlled trial aimed at understanding how a medically tailored meal plus nutrition counseling intervention worked for vulnerable individuals with lung cancer treated at four cancer centers across the USA. During the 8-month long study, participants in the intervention arm were asked to be interviewed, which were recorded, transcribed verbatim, and analyzed using conventional content analysis with principles of grounded theory.

RESULTS

Twenty individuals participated. Data analysis resulted in a theoretical explanation of the intervention's mechanism of action. The explanatory process includes three linked and propositional categories leading to patient resilience: engaging in treatment, adjusting to diagnosis, and active coping. The medically tailored meals plus nutrition counseling engaged participants throughout treatment, which helped participants adjust to their diagnosis, leading to active coping through intentional self-care, behavior change, and improved quality of life.

CONCLUSIONS

These findings provide evidence that a Food is Medicine intervention may buffer some of the adversity related to the diagnosis of lung cancer and create a pathway for participants to experience post-traumatic growth, develop resilience, and change behaviors to actively cope with lung cancer. Medically tailored meals plus intensive nutrition counseling informed by motivational interviewing supported individuals' adjustment to their diagnosis and resulted in perceived positive behavior change.

Unveiling the Chemistry of Citrus Peel: Insights into Nutraceutical Potential and Therapeutic Applications

The recent millennium has witnessed a notable shift in consumer focus towards natural products for addressing lifestyle-related disorders, driven by their safety and cost-effectiveness. Nutraceuticals and functional foods play an imperative role by meeting nutritional needs and offering medicinal benefits. With increased scientific knowledge and awareness, the significance of a healthy lifestyle, including diet, in reducing disease risk is widely acknowledged, facilitating access to a diverse and safer diet for longevity. Plant-based foods rich in phytochemicals are increasingly popular and effectively utilized in disease management. Agricultural waste from plant-based foods is being recognized as a valuable source of nutraceuticals for dietary interventions. Citrus peels, known for their diverse flavonoids, are emerging as a promising health-promoting ingredient. Globally, citrus production yields approximately 15 million tons of by-products annually, highlighting the substantial potential for utilizing citrus waste in phyto-therapeutic and nutraceutical applications. Citrus peels are a rich source of flavonoids, with concentrations ranging from 2.5 to 5.5 g/100 g dry weight, depending on the citrus variety. The most abundant flavonoids in citrus peel include hesperidin and naringin, as well as essential oils rich in monoterpenes like limonene. The peel extracts exhibit high antioxidant capacity, with DPPH radical scavenging activities ranging from 70 to 90%, comparable to synthetic antioxidants like BHA and BHT. Additionally, the flavonoids present in citrus peel have been found to have antioxidant properties, which can help reduce oxidative stress by 30% and cardiovascular disease by 25%. Potent anti-inflammatory effects have also been demonstrated, reducing inflammatory markers such as IL-6 and TNF-α by up to 40% in cell culture studies. These findings highlight the potential of citrus peel as a valuable source of nutraceuticals in diet-based therapies.

Diet in Food Insecurity: A Mediator of Metabolic Health?

Objective

Food insecurity (FI) is associated with poor metabolic health. It is assumed that energy intake and diet quality underlie this association. We tested the hypothesis that dietary factors (quantity and quality) mediate the association of FI with excess weight, waist circumference and glycemic control [glycohemoglobin (A1C)].

Methods

A mediation analysis was performed on data from the National Health And Nutrition Examination Survey using FI as an independent variable; body mass index (BMI), waist circumference, and A1C as metabolic outcome variables and total energy intake, macronutrients, and diet quality measured by the Healthy Eating Index-2015 (HEI-2015) as potential mediators.

Results

Despite a greater prevalence of obesity in participants experiencing FI, daily reported energy intake was similar in food-secure and -insecure subjects. In adjusted analyses of the overall cohort, none of the examined dietary factors mediated associations between FI and metabolic outcomes. In race-stratified analyses, total sugar consumption was a partial mediator of BMI in non-Hispanic Whites, while diet quality measures (HEI-2015 total score and added sugar subscore) were partial mediators of waist circumference and BMI, respectively, for those in the "other" ethnic group.

Conclusion

Dietary factors are not the main factors underlying the association of FI with metabolic health. Future studies should investigate whether other social determinants of health commonly present in the context of FI play a role in this association.
