Human Studies Recruitment
Children's Nutrition Supplement Study
Q: What is the purpose of this research study?
A: We are interested in knowing whether conjugated linoleic acid (CLA), a type of dietary fat, helps children gain less body fat as they grow.
Q: What is conjugated linoleic acid?
A: Conjugated linoleic acid (CLA) refers to a family of isomers, or types, of linoleic acid. CLA is a type of dietary fat that is found predominantly in dairy products and meat. The most common types of CLS are the 9,11 isomer and the 10,12 isomer. Most supplements sold in stores contain a 50/50 mix of both isomers. Many studies on CLA in adult humans show a tendency for reduced body fat. More details can be found in our informed consent document and at the product website, www.clarinol.com.
Q: Who can participate?
A: Boys and girls between the ages of 8 and 10 years who are overweight or at risk for becoming overweight but are otherwise healthy.
Q: What is overweight and at risk for becoming overweight?
A: We are defining overweight and at risk for becoming overweight as height and weight between the 85th and 98th percentile for your child's age and gender. Please use the following link if you would like to check your child's percentile. This link also contains instructions for accurately measuring height and weight at home. http://apps.nccd.cdc.gov/dnpabmi/Calculator.aspx

- You and your child will be asked to complete a total of 6 study visits during the six months. More detail about these visits can be found below and in our informed consent document.
Q: What will I get out of participating in this research study?
- Learn nutrition strategies from a dietitian.
- Learn about your child's body composition.
- Receive a gift card worth $25 at the beginning, month 2, month 4, and month 6 of the study.
- Receive a six month supply of chocolate milk containing CLA or sunflower oil placebo.
Q. When and where are the study visits held?
- Study visits are held at the UW Hospitals and Clinics (UWHC) and the UW Research Park Clinic (UWRP). Every other month you may be asked to pick up a new supply of chocolate milk at UW Nutritional Sciences.
- Visit 1, UWHC: This visit is at the beginning of the study, and is for a glucose tolerance test, a physical exam, and a meeting with a nutritionist. This visit will be scheduled on a Thursday morning. This visit will be at the UW Hospitals and Clinics and will last about 2 to 2.5 hours.
- Visit 2, UWRP: This visit is at the beginning of the study, and is for body composition testing. This visit will be scheduled on a Thursday afternoon. This visit will be at the UWHC Research Park Clinic and will last about 3 hours.
- Visit 3, UWHC: This visit is done after two months and is for blood tests and body weight measurement. This visit will be scheduled on a Thursday morning, and some Saturday mornings will also be available. This visit will be at the UW Hospitals and Clinics and will last about 30 minutes.
- Visit 4, UWHC: This visit is done after four months and is for body weight measurement. This visit will be scheduled on a Thursday morning, and some Saturday mornings will also be available. This visit will be at the UW Hospitals and Clinics and will last about 30 minutes.
- Visit 5, UWHC: Same as Visit 1 except is at the end of the six month study.
