Growing Up Today Study (GUTS)

Maintained/created by: Brigham and Women's Hospital & Harvard T.H. Chan School of Public Health



When GUTS began in 1996, researchers at Brigham and Women’s Hospital and Harvard School of Public Health were interested in studying how diet and exercise influence weight changes throughout a person’s life. They recruited children of Nurses’ Health Study participants—16,882 girls and boys between the ages of 9 and 14.The study expanded in 2004, when GUTS2 enrolled a new group of 10,923 children between the ages of 10 and 17.

Today, the team includes doctors, researchers, and statisticians throughout the US, and GUTS data is used by researchers across the globe. Nearly 100 research articles have been published as a result of their work.
