Kids with IBD (inflammatory bowel disease) often struggle with tiredness and difficulty doing everyday activities, which can make life harder, but there aren't good tools to measure these problems in children. This study aims to create special tools to measure fatigue and disability in kids aged 2-18. Researchers will talk to kids and their parents to find out what issues matter most and use this information, along with medical records, to design the tools. The goal is to help doctors track these problems better and improve care for children with IBD. This study is being done in collaboration with the Shaare Zedek Medical Center. Participants will be compensated for their time and effort, upon completion of the interview.

The Childrens Hospital of Philadelphia is seekinghealthy adolescents between the ages of 12-13, who are currently in the 7^thgrade,to participate in the Sleep and Growth Study 2. The purpose of this research is to learn more about the changes in sleep and body size in adolescents as they transition from middle to high school. Participants will be asked to visit CHOP so that we can measure their bone density. Following this visit, participants will wear a sleep tracker over a 2-week period and speak to a team member by phone on three occasions about the types of food eaten in the previous 24 hours. If you and your child agree to participate, the study will involve 3 visits over approximately 2 years. All participants are compensated for their time and effort.For more information and study details, please call 215-590-2383, ext. 1, or emails_grow@chop.edu.
