20 Clinical Trials for Various Conditions
To determine the feasibility and engagement of participants in the SUSTAIN intervention compared to enhanced usual care over 24 weeks through mixed-methods measurement of participant enrollment, adherence, retention, and engagement (counseling, screenings, referrals, and uptake). Methods: Leveraging rigorous quantitative and qualitative evaluation, the study team will identify mechanisms driving intervention feasibility and engagement. Hypothesis: SUSTAIN will be feasible with a high degree of engagement among Medicaid-enrolled participants with Stage 2 CKMS in comparison to enhanced usual care.
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.
Though the Mississippi Delta has a rich agricultural history and some of the nation's most fertile soil, residents have experienced the legacy of slavery and economic exploitation through food insecurity and poverty for generations. This project focuses on Bolivar, Washington, and Sunflower, contiguous counties in the Delta that are designated as health disparity populations. Over 65% of the 100,000 residents are Black/African American and \~30% live at or below the poverty level. Obesity rates are high and the rate of diabetes is almost double the national average. Tufts University received a grant from the National Institute of Minority Health and Health Disparities to develop, test, and evaluate a Food is Medicine program in Mississippi. The Delta Growing a Resilient, Enriching, Equitable, Nourishing food System (GREENS) Food is Medicine (FIM) Project, is a collaborative project in Bolivar, Washington, and Sunflower counties in Mississippi. The intervention involves regularly distributed fruit and vegetable produce boxes as well as nutrition education materials to the intervention group. The control group will receive produce boxes later, after they complete study activities. The project's primary goal is to improve health outcomes by creating a FIM intervention. The Delta GREENS FIM Project aims to become a model for promoting nutrition security and management of chronic conditions in varied communities nationwide.
The goal of this clinical trial is to learn if providing healthy meal kits to food insecure families can help lessen the social and emotional impacts of food insecurity on kids and their caregivers in rural Maine. The main questions it aims to answer are: 1. Is receiving healthy meal kits delivered to homes feasible and acceptable to rural Maine families? 2. Does receiving meal kits (along with an app to help learn how to cook the food) improve food insecurity and diet quality in rural Maine families? 3. Does receiving meal kits (along with an app to help learn how to cook the food) improve family function in rural Maine families? We will look at caregivers' stress, family conflict, household chaos, and child emotional-behavioral symptoms. Participants will: 1. Recieve and prepare a dietitian-designed meal kit with 10 meals per week for 4 weeks. 2. Receive free culinary medicine education via an app that they will continue to have access to after the study ends. 3. Complete a 1-1.5 hour virtual visit at the beginning of and end of the study.
The goal of this study is to understand the best practices for implementing produce prescriptions among adults with overweight or obesity experiencing nutrition insecurity. Enrolled participants will receive an 8-week intervention aimed at increasing nutrition knowledge, self-efficacy for healthy eating, and barriers to healthy food access. Participants will be randomly assigned to one of two produce prescription implementation strategies: Program 1: Participants will receive weekly produce vouchers that are redeemable at a local vendor. Program 2. Participants will receive fresh produce delivered directly to the participant's home. These boxes will be tailored based on household size, cooking and preparation preferences, and produce the participant prefers to receive. Researchers will compare engagement in and adherence to the intervention and the patterns of difference in 8-week changes in fruit and vegetable consumption and weight.
Study subjects with heart failure will receive either pre-prepared, home-delivered DASH/SRD-compliant meals incorporating local Navajo traditional foods or usual care for 30 days (14 meals weekly).
Study subjects with heart failure will receive either pre-prepared, home-delivered DASH/SRD-compliant meals incorporating local Navajo traditional foods or usual care for 60 days (14 meals weekly).
The goal of this study is to determine the appropriate target of medically tailored meals (a particular individual vs. the entire household) and means of delivery (a dedicated delivery driver vs. a commercial shipper), to inform subsequent medically tailored meal trials.
The goals of this study are to 1) pilot the feasibility of a novel meal kit delivery intervention in families and children with food insecurity and obesity and 2) evaluate the implementation of the pilot intervention.
The purpose of this three-year study is to develop, implement, and pilot test a culturally appropriate, multi-component nutrition intervention for people living with HIV and food insecurity in Honduras, which is among the Latin America nations with the highest HIV prevalence rates. The investigators specific aims are to: 1. Explore the relationships between food security, nutrition, and HIV treatment access, utilization, and adherence, and examine key mediators and moderators of these relationships. 2. Develop a multi-component nutrition intervention to address food insecurity among Honduran HIV+ individuals and their families. 3. Evaluate the preliminary effectiveness of the intervention on (1) food security and nutritional status; (2) HIV care retention (clinic attendance), uptake of ART when recommended, and ART adherence; and (3) clinical outcomes (CD4 count, ART side effects, and opportunistic infections). 4. Examine key mediators and moderators of the intervention effects from among characteristics of the patient, household, and contextual setting.
Food insecurity and low diet quality are persistent problems linked with chronic disease and poor health among limited-resource children and adults using Supplemental Nutrition Assistance Program (SNAP). We have shown nutrition education via adult-focused, direct SNAP-Education (SNAP-Ed) improved household food security by 25% but not adult dietary quality among SNAP-eligible households using a randomized, controlled, longitudinal SNAP-Ed intervention in Indiana. Households experiencing food insecurity often reserve food considered "healthful" for children, so child dietary quality improvement may precede that observed among adults when household food security improves. This study will determine the effect of adult-focused direct SNAP-Ed on child dietary quality and household food security using a longitudinal randomized, controlled SNAP-Ed intervention. Assessment will include repeated 24-hour dietary recalls to determine usual intake, the U.S. Household Food Security Survey Module, and behavior data from before and after the 10-week "intervention period," and 1 year later, after which the control group will receive the intervention. Low-income participants (n=275) from Indiana will be recruited following SNAP-Ed protocol. Results of the study will inform the creation of supplementary on-demand SNAP-Ed educational material focused on improving healthful dietary intake for children and adults in situations of food insecurity in households with children. Education on modeling healthy attitudes and behaviors, planning and preparing family meals, and dietary shortfalls as informed by the results and previous evidence will be included and evaluated. The study aligns with the goals of USDA to increase food security and this RFP to improve healthful behaviors, food quality and nutrition.
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.
The "digital divide" or gap in technological access and knowledge, for older adults has worsened during the COVID-19 pandemic, leading to disruptions in services like congregate meal programs funded by the Older Americans Act. Seven San Antonio congregate meal sites remained partially open biweekly to distribute meals but no longer offer in-person nutrition education, physical activity classes, and social activities. The proposed project will test the efficacy of digital nutrition intervention with at-risk older adults who attend congregate meal center in areas of high poverty and digital exclusion. The study is uses a stepped-wedge cluster clinical trial. Key community partners with the Department of Health Services Senior Services Division and Older Adult Technology Services (OATS) will participate in the planning phase, research design, and implementation of the study. The study aims are: 1. To test the impact of a technology-based intervention on the primary outcomes of food security and diet quality; 2. To determine the effect of the intervention on secondary outcomes of technology knowledge and usage, physical activity, and social isolation and loneliness; 3. To examine the long-term impact and sustainability of technology use on food security, diet quality, physical activity, and social isolation. If successful, the impact of this program could be applied throughout the national OATS network and to similar CMPs to bridge the digital divide beyond the COVID-19 pandemic
This is a pragmatic, pilot randomized controlled trial (RCT) of the Nutrition-Supported Diabetes Education Program (NU-DSMP). This study will test the feasibility and preliminary impact of providing diabetes-tailored food support and individualized case-management on glycemic control and other intermediate outcomes including food security, diet, mental health, and health care behaviors, among Medicaid-enrolled patients with type 2 diabetes in a safety-net county health system.
Eating healthy foods can help people manage health problems, like Type 2 diabetes and heart disease. Many people want to eat healthier, but changing eating behaviors is hard. Patients don't always know what foods to eat for their health problems and are hesitant to try foods that may be unfamiliar. These challenges are made more difficult when families have lower incomes, which makes accessing healthy foods difficult and trying new foods riskier when on a budget. Food is Medicine programs connect people to healthy foods that help them manage health problems. One example is a medically tailored grocery program. This program provides a patient with free groceries selected to help their medical condition. For example, a patient receives fruits, vegetables, whole grains, and low-salt, low-sugar foods if they have high blood pressure. Food resource coaching is another strategy for eating healthy food. This approach provides a coach that supports learning healthy eating habits when facing financial challenges by using available food resources. Among other strategies, a coach may teach the participant how to meal plan and shop at nearby stores to increase healthy and delicious eating patterns. In our study, the investigators will ask lower-income patients with at least one chronic health problem at a safety-net clinic if they want to participate in a Food is Medicine program. Patients that want to participate will be randomly placed in one of three groups. One group will get medically tailored groceries from a free food market for four months. Another group will get medically tailored groceries and food resource coaching from a free food market. The last group will get free food from the same market for four months, but food will not be medically tailored, and they will not meet with a coach. Participants will have the option to continue getting food from the market at the end of the study if they want to. This study will help us learn what patients think about Food is Medicine programs and how to best carry out these programs in the future. The study will also help us determine if providing medically tailored groceries and food resource coaching helps patients improve their diet. The investigators will use what is learned in this study to create a larger and longer program that can be provided in safety-net clinics throughout Dallas-Fort Worth. Our main goal is to build a sustainable and helpful program for patients that may not otherwise have access to healthy foods and eating habits that set the foundation for better health.
More than a dozen states have proposed or plan to implement work requirements in Medicaid, and similar requirements already exist nationally in the Supplemental Nutritional Assistance Program (SNAP), yet evidence on the effects of these policies is limited. In cooperation with the state of Virginia, the investigators plan to conduct a randomized controlled trial studying the impacts of work requirements in public programs on insurance coverage, SNAP participation, employment, and health, with a particular focus on changes in racial/ethnic and geographic disparities in these outcomes. The COVID-19 epidemic and concurrent economic downturn creates additional urgency around these issues, and the investigators will use a combination of national administrative data and a new population survey to assess disparities in employment, health care, and food insecurity during this crisis.
The goal of the study is to determine the immediate and long-term effects of SNAP-Ed on the food insecurity of the entire household, household adults, and household children. The study also aims to determine if there is a dose-response effect on food security after receiving 4 to 10 FNP lessons and if other characteristics influence the change in food security status.
This study aims to test a new online program we developed for parents and their preschool children, called CHEF-ED. CHEF-ED focuses on healthy cooking, parental feeding practices, and involving children in home food preparation.
This study will test the preliminary effects of an intervention to reduce sugary drinks among low-income parents (n=38)(primary caregivers) and their young children (6 months-3 year olds) compared to a control group (n=38). The main outcome is behavioral: sugary drink consumption (self-reported servings/day) among parents and among their children (parent-reported servings/day). These outcomes are measured at baseline and immediately after the 12-week intervention. An exploratory aim will test if the intervention has a sustained behavioral effect and an effect on body mass index and waist circumference of the parents 12 months after baseline. Our mixed methods multi-phase approach includes a quantitative component (randomized controlled trial - Aim 1) and a qualitative component (in-depth interviews and focus groups- Aim 2) to test the effects of a behavioral intervention to replace sugary drinks with water at home.
Improving diets through increased food and vegetable (F\&V) consumption significantly reduces the risk of cardiovascular disease (CVD). Programs increasing the accessibility and affordability of F\&Vs among low-income Americans have been hindered by the food consumption cycle associated with poverty: the tendency to over-consume calories shortly after receiving funds at the beginning of each month, draining the budget for F\&V purchases, or for all food purchases, by month's end. An emerging theory about dietary behavior suggests that providing funds for food in smaller installments distributed throughout the month will smooth the consumption cycle and improve healthy eating-counteracting the tendency to respond to lump sum, once-monthly funding installments by purchasing calorie-dense foods immediately after funds are received. The theory also suggests that funds targeted toward specific healthy foods (e.g., F\&Vs) will improve diets more than untargeted funds, despite the inconvenience of utilizing targeted funds. We will rigorously test both hypotheses in a real-world setting by comparing alternative approaches for delivering food purchasing vouchers. We have established and tested the infrastructure to provide vouchers accepted by numerous food sellers (e.g., supermarkets, corner shops) in low-income neighborhoods. Leveraging this infrastructure, we will conduct a randomized trial with a two-by-two factorial design, comparing $20 of vouchers valid for one month to four $5 vouchers each valid for a sequential week of the month (lump sum versus distributed funding), and comparing vouchers restricted to F\&V purchases to vouchers redeemable for any food (targeted versus untargeted funding). Low-income adults (N=288) recruited through our community partners will be randomized to one of four 6-month interventions: monthly targeted, monthly untargeted, weekly targeted, or weekly untargeted vouchers. Participants will be assessed through efficient verbal 24-hour dietary recalls validated among low-literacy populations, to determine daily consumption of F\&Vs and metrics of overall dietary quality at months 0, 6 and 12 (6 months after vouchers end). Additional surveys will identify moderators and mediators of dietary improvement.
