Key information for participants
Important GUTS research would not be possible without the commitment of our more than 27,000 participants. Thank you!
The longer you participate, the more valuable your data become. Every time you complete a questionnaire, you make GUTS a richer and more informative study.
Whatever your life experiences are, you have already contributed to a richness of data that can be harnessed to fight cancer, depression, pregnancy complications, heart disease, disparities in healthcare access, and other public health challenges.
No matter how long it has been since you last participated, we want to learn about your life as an adult today.
