Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) Study

The purpose of this research study — which is sponsored by the National Institute of Diabetes and Digestive and Kidney Disease (NIDDK) and is led by principal investigator Lorraine Levitt Katz, MD — is to collect blood and medical information to explore the relationships between candidate genes and type 2 diabetes mellitus, as well as obesity and insulin resistance. This work may lead to the development of new diagnostic tests and treatments for diabetes and other related diseases.

Who can participate

Anyone diagnosed with type 2 diabetes before 18 years of age who:

  • Has proof of Body Mass Index (BMI) above the 85th percentile at diagnosis
  • Does not have a genetic syndrome known to affect glucose tolerance other than diabetes

What participants will do

Eligible volunteers that give permission to participate through appropriate consent and assent forms will be asked to complete a single screening visit in which you can expect:

  • Interviews about your and your family’s medical history
  • A single blood collection for testing

The blood samples and information will be collected and tracked through a coded number to protect the privacy of all volunteers.

Participants will be compensated for their time and effort required to complete the study visit. Additionally, volunteers can be compensated for travel expenses if applicable.
