Middle-aged/older adults needed for compensated research study

From: Department of Human Nutrition, Foods, and Exercise

Middle-aged/older adults are being sought to participate in a study (IRB Protocol # 21-587) to learn if consuming artificial sweeteners have any impact on glucose levels in adults at high risk for developing type 2 diabetes. You may be eligible to participate if you are at least 45 years old. If you qualify, you will be compensated up to $500 upon successful completion of all study visits.

You will be provided all meals for 8 weeks to determine if two commonly consumed artificial sweeteners have an impact on glucose levels. You will be randomized into one of three groups: aspartame, sucralose, or control group.

This study involves 43 visits to the Virginia Tech's Blacksburg campus, over 9 weeks. Total time commitment will be about 34 hours. The study will include coming to the lab for breakfast each day for eight weeks (Monday-Friday) and taking your remaining food home for the day. Food for the weekend will be provided on Fridays.

Other assessments include a DEXA scan, two blood draws, four 24-hour urine collections, and wearing a glucose monitor and a physical activity monitor for one week at the beginning and end of the study.

You will be compensated a total of $500 upon successful completion of all study visits, all meals and snacks will be provided for 8 weeks, and you will receive health information regarding your body composition and glucose levels.
