Research Subject Recruitment

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

Study to compare online dietary recall with biological marker

Students over age 18 who speak English fluently are invited to participate in a study comparing a commonly used dietary recall method with two non-invasive biological markers.

Participants will complete three online dietary recalls and one scan of their hand or fingertip. The scan and the first survey will be completed with the researcher. The other two dietary recalls will be completed at the participants' convenience one day apart.

All data collection meetings with the research team will be approximately one hour. All information will be de-identified and used for research purposes only. Participants will be compensated with a $20 gift card for completion of all study components.

The purpose of this research is to better understand what methods are best to assess nutrient intake among college students. To register to participate or for more information, email Hannah Boeh at hboeh@purdue.edu.

Appetite study

Participants are needed by the Department of Nutrition Science to study appetite.

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

Men and women age 18 and over who are available during the morning for breakfast should contact Breanna at bmcarth@purdue.edu or visit www.cfs.purdue.edu/lsis. Participants will be compensated $10 upon completion of the study.

Women needed for a research study on effects of contraceptives on hormones and bone health

Women are needed for a research study investigating the effect of oral vs. non-oral contraceptives on bone health. Participants must be age 18-25, have regular menstrual cycles, and have not taken birth control pills/hormonal contraception in the last six months.

Participants can choose to take a contraceptive option or not during the study. Within the contraceptive use group, participants are randomly assigned to use of an oral contraceptive pill or the vaginal ring. Participants will receive measures of body composition, hormone levels, and aerobic fitness and a physical examination.

The study requires regular visits to the Department of Nutrition Science over the course of four months. The principal investigator is Connie Weaver, distinguished professor in the Department of Nutrition Science.

Those interested in participating should call Berdine Martin at 49-46559 or email FNbone@purdue.edu. In your phone call or email, mention the Contraception Study.

Study on effects of a single bout of exercise on cardiovascular risk factors

Tara Henagan and Humaira Gowher, assistant professors in the departments of Nutrition Science and biochemistry, respectively, are conducting a research study that will look at how a single bout of cycling exercise will influence changes in skeletal muscle and health during overweight and obesity.

For this study, participants will come to the Purdue Clinical Research Center for testing. Depending on the scheduling needs of participants, the study will consist of one to three days of testing. Testing will include measures of body composition (including percent body fat and lean mass muscle mass), clinical health parameters (i.e., blood pressure, heart rate, total, HDL and LDL cholesterol, glucose and insulin levels, lipid and epigenetic markers in muscle), filling out questionnaires related to health and physical activity, VO2max or cardiovascular fitness testing and one bout of cycling exercise lasting approximately one to two hours.

Participants will receive $200 for completing the study.

Men age 18 to 30 who are in general good health, are nonsmokers and have had a physical examination by a state-licensed M.D. or D.O. in the past two years or are willing to have a physical examination performed by a state-licensed M.D. or D.O. are eligible to participate. For more information, contact Prasad Devarshi at pdevarsh@purdue.edu or 765-586-3952.

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 daily 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.
