UC Davis Health Clinical Studies

A Study of an After-School Program to Teach Food Literacy in Food, Agriculture, Natural resources, and Human (FANH) sciences.

Volunteer for research at UC Davis and contribute to discoveries that may improve health care for you, your family, and your community!

UC Davis is doing a research study. We are asking you to allow your child to be a part of this research study because they are in the age group we would like to help and are a student at a local school. We would like to learn more about whether a new program helps children learn about nutrition, gardening, and being active. This project will focus on low-income communities. It will expand on existing after-school programs. Adolescents from these communities have higher high school dropout rates. Extracurricular activities, including after-school programs may help. They can improve graduation rates and increase college enrollment. This project plans to educate high school kids in food, agriculture, natural resources, and human (FANH) sciences. We will also motivate them to graduate high school, attend college, and major in FANH sciences. The project will empower adolescents to learn more and be excited about FANH sciences.

Online Developmental Screening Study

Have you had a new baby? Learn about your baby's development!

Researchers at the UC Davis MIND Institute on the UC Davis Medical Center campus in Sacramento are conducting an online study tracking the development of infants from 6 to 36 months of age. The goal of the study is to help parents understand their child’s development and gain access to resources when needed. This study tests new online methods of tracking developmental milestones in babies. The UC Davis MIND Institute is a collaborative international research center, committed to the awareness, understanding, prevention and care of neurodevelopmental disorders.

A Study of the Experimental EXPLORER PET/CT Medical Scanner in Healthy Volunteers

Help us test the performance of the world's first full-body EXPLORER scanner

We're inviting healthy volunteers to take part in an imaging research study. The purpose of this study is to test the performance of a new experimental medical scanner. The scanner, called EXPLORER, is the first total-body PET/CT medical scanner that is able to scan the entire human body and its organs at once. It is 40 times more efficient and has the potential to make a big impact in medical care and research. The EXPLORER scanner is the brainchild of UC Davis Health scientists envisioned 13 years ago as a scanner that could capture images quicker, better, or with less radiation than current scanners PET/CT scanning is a very safe medical imaging technique that tracks and maps out the movement of tiny amounts of radioactively-tagged sugars after injection in a body. Across the world millions of PET scans happen in patients each year.

Device Study
Any, age 18-100

Fiber Study

The purpose of this study is to determine if dietary fiber increases overall gut health

The purpose of this study is to investigate whether consuming a packet of fiber powder per day changes the composition and/or function of the gut microbiota and high density lipoproteins (HDL) or good cholesterol. If you take part in this research, you will be responsible to keep your normal diet with low fiber content, defined as less than approximately 15g/day, or equivalent to approximately 4 servings of fruit, vegetable, legume, or whole grain combined per day. You also need to attend all the visits until the endpoint of the study and provide all the questionnaires and biological samples as instructed under your consent.

Dietary Intervention Clinical Trial
Any, age 18-45

An Evaluation of the Health Education Theater Course

Volunteer for research at UC Davis and contribute to discoveries that may improve health care for you, your family, and your community!

The purpose of this study is to see if the enrollment in a course (entitled “Health Education Theater”) causes any changes in five major outcomes. These five outcomes include: (1) the knowledge about guidelines about (a) physical activity and (b) diet/nutrition. (2) compliance to these guidelines. The third outcome is (3) the economic efficiency (e.g., return on investment (ROI)) estimated by a cost-benefit analysis (CBA)). This will account for productivity loss (e.g., income loss) saved in the long-term (e.g., life time). The fourth outcome is (4) health related quality of life. The fifth outcome is (5) self-perception well-being measures such as self-esteem and and selfefficacy.

Behavioral study
Any, age 18 years or older

Koa Family: California's Obesity Prevention Project

This study hopes to learn if a new whole health program improves the health of low-income mothers.

The purpose of this study is to learn if a new whole health program improves the health of low-income mothers. To be eligible for this study, you must be a woman between the ages of 18 and 47. You must be comfortable speaking and reading English and be a mother (or caregiver) whose youngest child is between the ages of 3 and 17. You also must live in a low-income household (at or below 185% of the Federal Poverty Level), live in the Mack Road neighborhood of Sacramento or the City of Woodland, and have a cell phone that can receive text messages.

Behavioral study
Female, age 18 to 47 years old

A Study of the Effects of Intermittent Fasting on Energy, Hormones, Body Composition, and Performance in Male Runners

The study team hopes to learn more about how time restricted eating affects performance and health in male runners.

This study is designed to test the effects of four weeks of time restricted feeding (16 hours fasting and 8 hours feeding). These effects will be compared to four weeks of a more traditional eating pattern (12 hours fasting and 12 hours feeding). The study team will look at the following in male competitive runners: • Resting energy expenditure • Blood markers of metabolism and hunger • Body composition • Cardiovascular health • Substrate utilization (carbohydrate and fat burning) • Fitness
