Research Subject Recruitment

Would you like to be a subject in a nutrition research trial? The following studies are recruiting for subjects:

Study on calcium absorption

Connie Weaver, Distinguished Professor in the Department of Nutrition Science, and her research team are recruiting postmenopausal women > 50y of age to participate in a research study to begin in February.

This study will assess calcium (Ca) absorption from a novel form of Ca encapsulated with a protein compound compared to common forms of calcium used in supplements.

The study will take a minimum of 8-9 weeks to complete. After initial screening participants will have 4 separate 2-day phases of testing separated by at least 2 weeks. For the first day subjects will be provided food to consume and be asked to collect urine. On the morning of day 2 participants will come to Purdue Clinical Research Center. During each visit, participants will have an initial fasting blood draw, and consume a breakfast containing a special form of Ca. One hour later they will receive another special form of Ca administered via i.v. catheter, and 3h after blood will be drawn again. Lab visits will last approximately 5hr and food will be provided for the rest of the day. Other measurements will include 24hr urine collections, dietary intake records through out the study, and a bone scan during one of the clinical visits.

Participants will receive $220 for completing the study.

Those are interested in participating in this study are encouraged to contact fnbone@purdue.edu or call Berdine Martin at 765-494-6559 for additional information.

Study on bariatric gastric bypass or sleeve gastrectomy and iron status

Nana Gletsu-Miller, assistant professor in the Department of Nutrition Science, and her research team are recruiting women who has had bariatric gastric bypass or sleeve gastrectomy surgery in order to determine the risk of having iron deficiency.

Participants will have a study visit at the Purdue Clinical Research Laboratories, where a blood draw will be taken for measurement of iron status.

Women age 18 to 50 who have had gastric bypass surgery or sleeve gastrectomy are eligible. Compensation is $30.

To participate, contact Renee Mischler at rmischle@purdue.edu or 49-41860.

Study on effects of dailing timing of protein intake

This study will look at how within-day patterning of protein intake (even vs. skewed) combined with resistance training will influence changes in body composition, skeletal muscle and health during weight loss.

For this 18-week study, participants will come to the Purdue Clinical Research Center for eight testing days, which are before (baseline) and at the end of a 16-week weight loss intervention consisting of a controlled diet and resistance training program. Dietary counseling, gym memberships and personal trainers will be provided. Testing days will include measures of body composition (including muscle size), muscle strength and fitness, and clinical health parameters (i.e., blood pressure).

Participants will receive $1,000 for completing the study.

Men and women age 19 to 50 who are overweight, in general good health, nonsmokers, nonpregnant, and interested in participating in this study should contact Jan Green at jkgreen@purdue.edu or 49-47660 for more information.

The principal investigator is Wayne Campbell, professor in the Department of Nutrition Science.

Study on the impact of drinking common beverages with breakfast on blood glucose and insulin levels

Participants are being sought to participate in a study that will look at how drinking different common beverages (milk, low-fat milk, nonfat milk, orange juice, coffee and water) with a meal changes blood sugar and insulin levels after eating.

Participants will come to Purdue Clinical Research Center on six mornings separated by at least one week. On each of the mornings, participants will consume a breakfast with one cup of a beverage. Blood samples will be taken before and every 30 minutes after eating for four hours to test blood sugar and insulin levels. Each test day will last about five hours.

Measurements include calories and nutrients in the participant's diet, weight/height/lean tissue, and blood glucose and insulin levels. Participants will receive $500 for completing the study.

Men and women ages 35 to 65 who are overweight, nonsmoking, not pregnant and interested in participating in this study should contact Jia Li at milks37@purdue.edu or 49-41706 for more information.

The principal investigator is Wayne Campbell, professor in the Department of Nutrition Science.

Almonds and weight management study

Participants are needed by the Department of Nutrition Science to study the role of almonds in weight management. 

The principal investigator for the study is Richard Mattes, Distinguished Professor of Nutrition Science.

Men and women age 18-60, overweight but generally in good health, who have no nut allergies and who are interested in participating in this study should contact Jaapna at almeal@purdue.edu.  Participants may earn up to $200 upon completion of the study.
