Screening Survey - Acute Artificial Sweetener Feeding Study


This is a screening survey for our artificial sweetener feeding study. This survey will help us see if you are potentially eligible to participate in this study. Following the completion of this survey, we will contact you with the next steps. If you meet the criteria for this pre-screening survey, we will send you an informed consent document which outlines the specifics of the study. We will go through this document in detail at the first visit before any additional eligibility testing is conducted. To confirm if you meet the criteria for this study through additional testing, we will invite you to come to our lab on the Virginia Tech campus. Briefly, the full study consists of 2 fingerstick blood samples, 3 controlled breakfast meals, and 3 blood draws over a 1-month period. That means you will eat all of the breakfast foods that we provide for you on the 3 visits, and we cannot accommodate special diets/diet restrictions as the meals are standardized for all participants. You will come to the lab each visit for a standardized breakfast including a beverage and capsules that may or may not contain artificial sweeteners. You will undergo a baseline blood draw to measure your glucose levels, then eat your breakfast, and we will then measure changes in your glucose levels over a 2-hour period. The three visits will be randomized for you to receive either aspartame (Equal), sucralose (Splenda) or a control condition. All of the groups will be blinded - neither you or the researchers (besides the study coordinator) will know which group you are in. By the end of the study, you will have experienced each group once. We will be examining if consuming artificial sweeteners has any impact on glucose levels. In addition to receiving these meals, and information regarding your health, you will be compensated a total of $75 for completing all study visits.

Your participation in this study is completely voluntary. There are no foreseeable risks associated with completing this survey. However, if you feel uncomfortable answering any questions, you can withdraw from the survey at any point.

Your survey responses will be strictly confidential and data from this research will only be shared with the project director and project coordinator. Your information will be coded and will remain confidential. If you have questions at any time about the survey or procedures, you may contact Dr. Valisa Hedrick by email at vhedrick@vt.edu
