Sleep Extension for Circadian Rhythm Disorder

Cincinnati, Ohio
There is strong reason to believe that sleep promotion during adolescence could yield long-term health rewards; the investigators' data show that, when they get more sleep, Morning Larks have impressively reduced intake of overall calories and foods high in glycemic load that are linked to long-term health risk. Before that can be translated into major public health interventions, however, the field needs to understand why similar changes in sleep had no effect, or even an adverse effect, on adolescent Night Owls. This experimental study will clarify why there have been such discrepant effects across Morning Larks and Night Owls, with the goal of more broadly harnessing the promise of improved sleep in the prevention of obesity and long-term morbidity.

Video Education for Health Maintenance

Livonia, Michigan
It is widely accepted that prevention is far more impactful than curative medicine and must be included in primary care. In a previous pilot study, we evaluated passive video preventive lifestyle education in the emergency department. The current study is a randomized prospective trial assessing the practicality and impact of a brief interactive educational video intervention to patients during primary care clinic visits.

Nutrition Education for Healthy Eating and Food Security

West Lafayette, Indiana
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.

Personalized Nutrition for Health Optimization

Chicago, Illinois
The goal of this investigational study is to develop algorithms that predict human response to foods. The main question it aims to answer are: * How does varying foods and eating patterns impact one's biological and physiological responses? * In what ways can novel dietary assessment measures be used to improve dietary assessments and to prescribe assessments to people in future research with increased precision? * Can artificial intelligence and machine learning techniques be combined to prescribe foods and eating patterns to individuals for optimization of their health? There are 3 Modules participants may take part in: * Module 1- A participant's dietary intake and accompanying nutritional status, biological and other measures will be observed over 10 days, as well as physiological responses to a liquid mixed meal tolerance test will be measured. * Module 2- Participants will undergo three controlled dietary interventions provided for 14-days each and separated by washout periods of at least 14 days. Physiological responses following a diet-specific meal test will be measured. * Module 3- Participants will undergo the same three dietary interventions during the same 14 day periods as Module 2 while being studied in-residence. Physiological responses following a liquid mixed meal tolerance test and a diet-specific meal test will be measured.

Sleep Extension for Improved Health in Adolescents

Aurora, Colorado
Many teenagers do not get enough sleep. Obesity and diabetes are increasing in teenagers as well. This study plans to learn more about sleep and insulin resistance (insulin not working) in teenagers, and how these things may be related depending on sleep. This is important to know so that the investigators understand how sleep may play a role in health conditions like extra weight gain (increased food intake and less physical activity) and diabetes. To answer this question, the investigators plan to enroll teenagers who get \<7 hours of sleep on school nights and measure changes in insulin sensitivity and dietary intake after a week of typical sleep (sleeping on their normal school schedule) and a week of longer sleep (spending 1+ hour longer in bed each night).

Modified Breath Test for Sedentary Lifestyle

Toronto, Ontario
Developing tools to detect when our bodies are more resistant towards protein synthesis is valuable for identification of when someone may be at risk of losing body or muscle mass such as with aging or certain diseases. The current study aims to refine our previous breath test method to be more effective at measuring changes in how the body processes protein in different situations, such as resting, reducing physical activity, and doing resistance exercise. We hypothesize that using a lower amount of dietary amino acids in our breath test will be effective at detecting lower amounts of amino acids used after exercise, and a greater amount with step reduction compared to normal activity levels

"I was diagnosed with stage 4 pancreatic cancer three months ago, metastatic to my liver, and I have been receiving and responding well to chemotherapy. My blood work revealed that my tumor markers have gone from 2600 in the beginning to 173 as of now, even with the delay in treatment, they are not going up. CT Scans reveal they have been shrinking as well. However, chemo is seriously deteriorating my body. I have 4 more treatments to go in this 12 treatment cycle. I am just interested in learning about my other options, if any are available to me."

"I have dealt with voice and vocal fold issues related to paralysis for over 12 years. This problem has negatively impacted virtually every facet of my life. I am an otherwise healthy 48 year old married father of 3 living. My youngest daughter is 12 and has never heard my real voice. I am now having breathing issues related to the paralysis as well as trouble swallowing some liquids. In my research I have seen some recent trials focused on helping people like me."

Frequently Asked Questions

How much do Dietary Habits clinical trials pay?

Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.

How do Dietary Habits clinical trials work?

After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across Dietary Habits trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length for Dietary Habits is 12 months.

How do I participate in a study as a "healthy volunteer"?

Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.

What does the "phase" of a clinical trial mean?

The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.

Do I need to be insured to participate in a Dietary Habits medical study?

Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.

What are the newest Dietary Habits clinical trials?

Most recently, we added Food Swaps for Healthy Eating, Video Education for Health Maintenance and Front-of-package Labels for Dietary Behavior to the Power online platform.
