Produce Prescriptions and Veggie Meter Scores for College Food Security

The goal of this pilot intervention study is to learn if providing weekly produce boxes helps college students who struggle to afford healthy food. It will also test if this program is practical to run on a college campus. The main questions it aims to answer are: * Does receiving free produce boxes increase students' fruit and vegetable intake? * Does the program improve students' food security and nutrient levels in the skin? Researchers will measure skin carotenoids (a marker of healthy eating) using a non-invasive finger scan called a Veggie Meter to see if the produce boxes improve nutrition biomarkers. Participants will: * Receive one free box of fresh fruits and vegetables plus printed nutrition education materials every week for 8 weeks. * Visit the campus site at the start, week 4 and end of the study \[week 8\] for a finger scan, measure their weight and to complete surveys. * Provide feedback on their experience with the produce boxes and their food access.

The Food for Health Study

The project, called Food for Health (F4H), will study a new Produce Prescription Program (PPP) designed for rural Native American older adults. The study is based in the Confederated Salish and Kootenai Tribes (CSKT) of the Flathead Indian Reservation in Montana. In this community, many older adults face food insecurity and higher risk for Type 2 Diabetes (T2D). The tribal health department (THD) and local Food Resource Center (FRC) already provide important health and food support services, and this project builds on these strengths. Produce Prescription Programs (PPPs) is a type of nutrition support intervention that connects healthcare providers with local food programs to help patients access fresh, healthy foods. For example, an individual enrolled in the study will be "prescribe" fruits and vegetables in the form of a vouchers or coupons, which can be used to buy these foods at local food centers. Research shows that this type of program can reduce food insecurity, improve diet, and support better health. PPPs also fit well with tribal community priorities by supporting food sovereignty, culture-based nutrition education, and a stronger local food system. A key part of the study approach is using Community-Based Participatory Research (CBPR). CBPR means that community members, health providers, and researchers work together as equal partners. This way, the program is not just designed "for" the community, but "with" the community. The CSKT THD and community members have been involved in shaping this project from the start, and their priorities-like food security and food sovereignty-are at the center of the work. The investigators will carry out the study in two phases. Phase 1: Investigators will pilot test the acceptability of F4H in a small group of older adults (N=10) to understand the program's acceptability. The results will be used to refine and improve the program before moving to the next phase. Phase 2: Investigators will test the feasibility and impact of the refined F4H program with a larger group of older adults (N=33). Participant food insecurity and T2D risk factors, such as blood sugar and weight, will be measured before and after the program. Investigators expect that participants will have less food insecurity and healthier measures after completing the program. The clinic-to-community model is central to F4H. The THD will provide the prescriptions, and the FRC will be where participants redeem vouchers for fruits, vegetables, and other nutritious foods. The program will also include nutrition education that is grounded in Native culture and values. This model helps strengthen connections between healthcare and community services, creating a more supportive system for older adults. In addition to testing the program, investigators will study how it is carried out. This is called implementation research. It means paying attention to how the program fits into the community setting, what helps it succeed, and what barriers might need to be addressed. Understanding these factors is important so that the program can continue in the future and potentially be expanded to other Native communities. The long-term goal of F4H is to empower Native American communities to improve nutrition and reduce health disparities. By supporting older adults in gaining better access to healthy foods, the aim is to lower diabetes risk, improve quality of life, and strengthen local food systems. If the program is successful, it can serve as a model for other rural communities facing similar challenges.

RUSH Food is Medicine Veggie Rx - GusNIP Produce Prescription

The goal of this clinical trial is to assess nutrition incentives and produce vouchers to measure the impacts of food insecurity-related chronic health conditions in adults with hypertension and/or diabetes. The main questions it aims to answer are: * Does participation increase fruit and vegetable consumption for participants? * Does participation reduce individual and household food insecurity? * Does participation reduce healthcare utilization and associated costs? * Does participation lead to improvements in diet-related health outcomes (e.g., hypertension, diabetes)? * Does participation support the local economy by increasing participant spending at local food vendors? Participants will: * Receive 6 months home delivered produce prescription boxes * Receive 6 months match of produce vouchers * Receive nutrition education and participate in Chronic Disease Self-Management classes

Food Sequencing in Food Insecurity

The purpose of this study is study the impact of meal sequencing when added to standard care in individuals with diabetes mellitus/prediabetes who receive produce boxes as part of a food insecurity program. Meal sequencing is a way of eating where proteins and vegetables are consumed before carbohydrates. Eating proteins and vegetables first has shown to cause lower post meal glucose levels compared to eating carbohydrates first in a meal. The investigators believe participants with prediabetes or diabetes mellitus experiencing food insecurity enrolled in a produce delivery program and receive meal sequencing counseling will have improvement in glucose levels and dietary quality compared to those who are enrolled in the produce delivery program and receive standard nutritional counseling.

Food Access, Value, and Optimization of Resources

The main goal of the study is to examine the potential benefits of an educational workshop designed to help and support caregivers of children in families that struggle to get enough healthy food. The main questions are: * Does the FAVORes workshop impact household food and nutrition security? * Does the workshop change caregivers' knowledge, beliefs, and skills related to healthy food access? Participants will: * Attend four weekly in-person sessions (in English or Spanish) * Complete short surveys * Be interviewed after the workshop is completed (optional)

The Effect of Grocery Support Dose on Food Insecurity and Disease Control Among Covered California Members With Diabetes or Hypertension

This continuation study is a pragmatic randomized controlled trial (RCT) of Covered California's Grocery Support Program among low-income participants with diabetes or hypertension. This pragmatic RCT will compare the efficacy of providing different benefit amounts ($80 vs. $120) via a monthly food card benefit for households where at least one adult has diabetes and/or hypertension and incomes below 250% of the federal poverty level (FPL).

Food Insecurity Reduction & Strategy Team

This study seeks to address the multifaceted challenges posed by food disparities and their negative consequences on health outcomes, via a comprehensive community health intervention program. Study objectives include: 1. To describe the social-demographic and clinical factors associated with food insecurity in the hospitalized diabetic population. 2. To design, implement and evaluate a nutrition program targeting the hospitalized diabetic population. The investigators will prospectively randomize the target population into either a nutrition program (Intervention), or state-of-art standard of care (SOC) in a 4:1 ratio. Participants in the intervention group will be provided the following two resources in addition to SOC: 1) Enhanced access to nutritious food (twice daily meal delivery up to 90 days post-discharge) 2) Education at discharge and continuing outreach to enhance knowledge for better diet and food options. 3. To enhance community engagement and develop a systematic implementation plan for long-term roll-out of the nutrition program.

Assessing the Effects of Cool Roofs on Indoor Environments and Health in Colima, Mexico

Ambient air temperatures in Mexico have broken record highs in 2024. Solutions are needed to build heat resilience in communities and adapt to increasing heat from climate change. Sunlight-reflecting cool roof coatings may passively reduce indoor temperatures and energy use to protect home occupants from extreme heat. Occupants living in poor housing conditions in the northern zone of Mexico are susceptible to increased heat exposure. Heat exposure can instigate and worsen numerous physical, mental and social health conditions. The worst adverse health effects are experienced in communities that are least able to adapt to heat exposure. By reducing indoor temperatures, cool roof use can promote physical, mental and social wellbeing in household occupants. The long-term research goal of the investigators is to identify viable passive housing adaptation technologies with proven health benefits to reduce the burden of heat stress in communities affected by heat in Mexico. To meet this goal, the investigators will conduct a cluster-randomized controlled trial to establish the effects of cool roof use on health, indoor environment and economic outcomes in Colima, Mexico.

Feasibility of an ADAPTive Intervention to Improve Food Security and Maternal-Child Health

Food insecurity affects up to 30% of pregnancies and leads to worse health in pregnant people and their children, including an increased risk of gestational diabetes, pre-term birth, and future cardiometabolic chronic conditions (e.g., type 2 diabetes and obesity). Interventions are being utilized to address food insecurity in clinical care settings, but patients differ in the support needed to reduce food insecurity and health systems have limited resources to invest in these interventions. Rather than a single intervention, adaptively allocating interventions could be a more effective, equitable, and efficient approach to improve food security; the objectives of this pilot study are to determine the feasibility of recruiting, retaining, and adaptively providing food insecurity interventions to pregnant patients in anticipation of a large, definitive trial in the future.

Optimizing Online Purchasing of Fruits, Vegetables, and Legumes for Low-Income Families

Food insecurity, that is, the lack of consistent access to nutritious and affordable food, is associated with poor diet, increased cardiovascular disease (CVD) risk, and has a negative long-term impact on the economy through increased health care costs. CVDs and food insecurity disproportionately affect Black and Hispanic families, and most of these racial health disparities can be attributed to social determinants of health, including poor access to healthy foods. A recent policy in the U.S. authorized the Supplemental Nutrition Assistance Program (SNAP) benefits to be used online to increase grocery access and promote healthy eating. Although online grocery shopping has been growing among populations of low-income, the selection of fruits, vegetables, and legumes (FVL), which are protective against CVD, is lower than in-store. Distrust of online hired shoppers' choices, fear of losing money on unsatisfactory purchases, and impulse of unhealthy food purchases have been the major barriers to online healthy food selection. Thus, there is a need for intervention packages that are effective, economical, and easily scalable into policies that address CVD-related outcomes and improve health equity. The proposed work will use a highly efficient methodological approach, the Multiphase Optimization Strategy (MOST), to test three experimental components aimed at barriers to online healthy food selection, called OPT-FRESH. This approach addresses weaknesses in prior studies, which cannot determine which elements of multicomponent interventions meaningfully improve outcomes. 360 families with children living in low-income urban communities of NYC will be randomized to receive some combination of the three experimental components for 12 weeks: 1) weekly text messages to improve the trust in online grocery services (off/on); 2) weekly match-up to $10 as a financial incentive for purchasing FVL online targeting loss aversion (off/on); 3) weekly instant shoppable grocery lists of culturally tailored meal suggestions using SNAP recipes targeted at impulse purchases (off/on). Delivery fee waiver and a tutorial video addressing digital literacy will be constant components to promote equity in participant enrollment. Aim 1 will determine the combination(s) of the three experimental components that improve overall household FVL purchase and food insecurity (primary outcomes) and FVL intake of children (secondary outcome). Aim 2 will identify the optimized intervention that balances component(s) that are affordable and scalable (high adoption, implementation, maintenance) that still produce meaningful effects on the outcomes, using decision analysis for intervention value efficiency. Aim 3 will determine the mechanistic effects of the three intervention components on the outcomes using factorial mediation analysis. Working with community-based organizations and nutrition and hunger relief programs in NYC, a grocery delivery service, and a team with unparalleled expertise in experimental trials, policy, and MOST, we will implement optimized, affordable, and scalable intervention strategies to improve neighborhood food access and ultimately CVD outcomes in socially vulnerable families.

Assessing the Effects of Cool Roofs on Indoor Environments and Health

Ambient air temperatures in Asian, Latin American, African, and Pacific climate hotspots have broken record highs in 2024, driven by man-made climate change. Solutions are needed to reduce heat exposure in communities. Sunlight-reflecting cool roof coatings passively reduce indoor temperatures and energy use to protect home occupants from extreme heat. Occupants living in poor housing conditions globally - for example in informal settlements, slums, and low-socioeconomic households - are especially vulnerable to increased indoor heat exposure. Heat exposure can instigate and worsen numerous physical, mental and social health conditions. The worst adverse health effects are being experienced in communities least able to adapt to heat exposure. By reducing indoor temperatures, cool roof use can promote physical, mental and social wellbeing in occupants. The long-term research goal is to identify viable passive housing adaptation technologies with proven health and environmental benefits to reduce the burden of heat stress in communities affected by heat globally. To meet this goal, the investigators will conduct a cluster-randomized controlled trial to establish the effects of cool roof use on health, indoor environment and economic outcomes in five urban climate hotspots: Ouagadougou, Burkina Faso; Colima, Mexico; Ahmedabad, India; Niue; and Tavua, Fiji.

Nurturing Outreach for Understanding and Reducing Inpatient Security of Health

Food insecurity is the lack of consistent access to the food needed for a healthy life. Food insecurity among families whose child has been hospitalized is a critical problem affecting a large, vulnerable population. The purpose of this study is to identity the most effective ways to help those families with food insecurity.

MISAPSY: Childhood Maltreatment, Food Insecurity, Psychological Distress and Professional Integration Among Socioeconomically Disadvantaged Young Adults

The MISAPSY study (Childhood Maltreatment, Food Insecurity, Psychological Distress and Professional Integration Among Socioeconomically Disadvantaged Young Adults) aims to model the complex interrelations between child maltreatment, trauma exposure, food insecurity, and psychological distress among precarious young adults enrolled in French youth employment and social integration services (Mission Locale). Adopting a methodology structured around three complementary components, this study consists of: (1) a cross-sectional survey to identify key associations ; (2) a qualitative study based on semi-structured interviews exploring psychologists' subjective experiences, and (3) a longitudinal comparative interventional study involving two different support programs to assess and compare the impact of these interventions on participants' food insecurity and psychological well-being. Using a multi-phase design, MISAPSY seeks to move beyond linear risk-factor models by adopting a systemic and network-based approach to mental health and social vulnerability. The study integrates quantitative analyses, including network analyses, qualitative exploration of professional practices, and comparative longitudinal intervention to inform more holistic, equitable, and transferable models of care for vulnerable young adults.

Delivering Food Resources & Kitchen Skills (FoRKS) to Adults With Food Insecurity and Hypertension

The goal of this clinical trial is to determine the impact of a home-delivered foods and kitchen skills program on health and nutrition in adults with high blood pressure and food insecurity. Researchers will compare Food Resources \& Kitchen Skills (FoRKS) and Enhanced Usual Care (EUC) to evaluate the effects on mean systolic blood pressure (SPB), HbA1c, food security and nutrition. Participants will complete 24-hr blood pressure monitoring, standard blood pressure measurements, weight, finger stick for A1c point-of-care testing, and questionnaires.

Addressing Food Insecurity: Plant-Based Food Prescription Program

Reduce food insecurity by improving plant-based health food consumption, access, health and nutrition literacy and the health of the food-insecure families we serve.

Penn Produce Prescription and Chronic Kidney Disease Study

The goal of this pilot clinical trial is to examine the feasibility, acceptability, and likely effect of a produce prescription intervention on patient-centered outcomes, health behaviors and health outcomes, among food insecure adults with chronic kidney disease stages 3 - 5. Participants will complete surveys at three timepoints, each three months apart, and complete health measurements at two timepoints 6 months apart. Half of the participants will be randomly assigned to the treatment where they will receive produce prescriptions with amount of the vouchers depending on their reported family size, every two weeks over six months. Researchers will compare the treatment group and the control group to see if there are any improvements in patient-centered outcomes (food and nutrition insecurity, health-related quality of life, depression and anxiety) and clinical outcomes (diet quality, metabolic acidosis, serum albumin, estimated GFR, blood pressure, and HbA1C).

Behavioral Economics to Implement Nutrition Ranking in Food Pantries

The goal of this randomized controlled trial is to test whether using behavioral economic strategies to promote healthy food choices on a food bank's online ordering platform increases the use of the traffic light nutrition ranking system and increases healthier food selections by the food agencies (e.g., food pantries) who use the food bank.

Nutrition and Obesity in Under-Represented Populations: Food Insecurity Research to Advance Science and Improve Health

Food insecurity is associated with obesity in children, and childhood obesity leads to long term health consequences. While existing research shows that food benefit programs reduce food insecurity, little is known about the mediating factors between food benefit programs and child health. The purpose of this study is to understand if the resolution of food insecurity in young children with early onset obesity can improve body mass index (BMI) over one year, and if so, by what mechanisms. The investigators will conduct a randomized comparative effectiveness study among infants (n=228) aged 12 months at risk for food insecurity and deliver two different food security interventions. Both will provide families with $50/week for one year of study enrollment. The first group will receive this as an unrestricted cash benefit ("cash benefit group") and the second group will receive this as a benefit in the form of weekly grocery purchases with the support of a trained nutrition expert to guide healthy grocery purchasing ("grocery benefit group"). The investigators will also construct a contemporary comparison cohort of infants meeting the inclusion/exclusion criteria from the electronic health record, using propensity score matching to allow comparisons between both intervention groups and usual care. The primary endpoint is difference in BMI at 12 months post-enrollment (24 months of age). Secondary outcomes include measures of nutrition, food security, electronic health record data related to general child health, and other factors related to parental stress and unmet social needs. Patients will have the opportunity to participate in post-study interviews to report on intervention satisfaction, and facilitators and barriers of infant feeding. Data analysis will be conducted by a trained statistician (Duke Biostatistics, Epidemiology, and Research Design; BERD) and will employ a two-means test for a repeated-measures design. The benefits to participants outweigh the minimal risks of loss of privacy, and confidential information will be managed carefully to minimize this risk.

Urban Gardening and Peer Nutritional Counseling for People With HIV and Food Insecurity

The investigators are conducting a fully powered cluster randomized controlled trial (RCT) of a culturally appropriate, multicomponent intervention combining peer nutritional counseling with urban gardening among people with human immunodeficiency virus (HIV) in the Dominican Republic (DR) to assess efficacy, analyze mediators of effects, and evaluate detailed process data to inform scale-up. The study will examine the impact of the intervention on participants' HIV clinical outcomes (HIV viral load, antiretroviral therapy adherence, and HIV care retention) as well as intermediate outcomes such as food security and HIV-related stigma.

Evaluating an Enhanced Home-delivered Meal Program on Older Adults' Health and Well-being

Meals on Wheels of Rhode Island (MOWRI), in partnership with the University of Connecticut (UConn), will implement and evaluate an enhanced version of its Home-Delivered Meals Program (HDMP). The project goal is to implement and test the effectiveness of an enhanced Home-Delivered Meals (HDM) service delivery approach. The enhanced approach includes community health worker (CHW) interactions and supplemental healthy grocery bags to address diet quality, food and nutrition security, loneliness, and health-related quality of life for older adults. MOWRI participants at the highest nutritional risk will be randomized to receive standard or enhanced services in order to test the effect of the intervention on health-related outcomes. Anticipated outcomes for individuals receiving enhanced services are improvements in measures of diet quality, food and nutrition security, loneliness, and health-related quality of life compared with those receiving standard HDM services.

An Agricultural Livelihood Intervention for Pregnant Women

Scarcity of food is a leading cause of sickness and death in mothers and their newborns in sub-Saharan Africa. Use of locally acceptable agricultural interventions including provision of agricultural supplies, training and having model farms can go a long way to alleviate the ills of food scarcity among mothers and children in our region. This study is designed to learn whether an agricultural intervention might prevent food scarcity and illness among mothers and children. A total of 410 pregnant women will be enrolled from 9- 20 weeks of pregnancy, half living with HIV. Women will be randomly assigned to receive the intervention right away or to receive the intervention after the study is over if they are interested. Follow-up on enrolled participants will happen at a specified period of time, up to 12 months postpartum. The central hypothesis is that by empowering pregnant women with skills and commodities for sustainable farming, the intervention will lead to better maternal and infant health compared to control participants. The study intervention includes the provision of agricultural commodities (including irrigation pumps seeds, and other supplies) training on agriculture and business, and a demonstration farm where all trainings will be held and where women can harvest vegetables to bring home. The study aims to explore the impact of the intervention on health outcomes as well as socioeconomic and behavioral factors among the study population. This research will significantly advance scientific understanding of the importance of such agricultural interventions for pregnant women and their infants in the first year of life.

Implementing Food Referrals for Equity and Sustained Health

Food insecurity (FI) disproportionately affects those who have been historically marginalized and significantly contributes to poor health outcomes. In children, FI is associated with lower psychosocial functioning and academic achievement. It also contributes to the development of adverse health outcomes such as obesity, type 2 diabetes mellitus (T2DM), cardiovascular disease (CVD), and Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD). Improving the diet quality of children (e.g., decreasing fat intake, increasing fruits and vegetables (FV) and fiber intake) has been associated with lower fasting serum glucose, insulin, LDL cholesterol, non-HDL cholesterol, and reduced risk of CVD later in life. Increasing awareness and access to programs that promote food equity by providing affordable healthy produce is a promising way to improve health outcomes and empower patients and communities to achieve better health and well-being. The goal of this proposal is to refine and optimize implementation strategies that connect families to community-based food security nutrition support programs through health care systems or medical clinics. The investigators will develop a multi-disciplinary, cross-sector collaboration to optimize current processes and workflows that integrate food security nutrition support programs into the healthcare system. The investigators will also work to develop a closed-loop communication system between the healthcare and healthy food access systems to support greater patient autonomy and self-efficacy to obtain, prepare, and consume healthy foods.

CHW Intervention to Improve Nutrition Security of Patients With Hypertension

The goal of this study is to implement and evaluate a randomized pilot study of a 4-month Nutrition-enhanced community health worker (CHW) intervention for primary care patients with nutrition insecurity and poorly controlled hypertension. The nutrition intervention will be added to the pre-existing Massachusetts General Hospital CHW hypertension (Basic CHW) program that provides hypertension education, coaching about adherence to medications and primary care visits, and home BP cuffs and promotion of BP self-monitoring over the course of approximately 4 months.

Neonatal Neurodevelopmental Outcomes

The main goal of this research is to help mothers with depression and anxiety to cope and bond with their baby. The next goal is to provide resources to help with household needs like food, rent, or utility assistance, health insurance. Our theory is that helping with food insecurity, household needs, and emotional health will help children and families.
