Brief Summary

The goal of the DISCOVERY study is to provide innovative critical information regarding the unique natural history of glycemic control, insulin sensitivity, and β-cell function, and their mechanistic ...

Detailed Description

The DISCOVERY study will extensively phenotype a large cohort of youth at-risk for type 2 diabetes, as they transition through puberty, and characterize the course of dysfunction in pathophysiological...

Eligibility Criteria

Inclusion

  • Screening will occur to enrich the yield of individuals who are highly predisposed to develop youth-onset type 2 diabetes and include those with all of the criteria in Category A:
  • Overweight or obesity with BMI ≥85th percentile
  • Age 9-13 year for girls, 10-14 year for boys (inclusion younger for girls as puberty tends to start a year earlier in girls)

  • Elevated HbA1c 5.5-6.4%
  • Participants who meet all of these categories will further need to meet at least one criterion in Category B:

  • Severe obesity (BMI ≥99th percentile)
  • Personal history of intrauterine growth restriction (IUGR), small for gestational age (SGA), or low birth weight

  • Diabetes based on history, or HbA1c ≥6.5% in the medical record or at screening
  • Unable/unwilling to provide consent/participate fully
  • Conditions predisposing to diabetes or altering the trajectory of puberty (transplant, cancer, Down Syndrome, Turner Syndrome, Klinefelter Syndrome, ovarian/testicular failure, etc.)
  • Medications affecting glucose dynamics during the screening and enrollment period (oral steroids, inhaled steroids \>1,000mcg/day past month, atypical antipsychotics, topiramate)
  • Prior treatment with insulin
  • Use of glucagon-like peptide-1 (GLP-1) receptor agonist or any weight loss medications in the 6 weeks prior to enrollment
  • Planning treatment with glucagon-like peptide-1 (GLP-1) receptor agonist or any weight loss medications
  • Use of metformin or any glucose lowering medication for a reason other than treatment of diabetes (e.g., for PCOS) in the 6 weeks prior to enrollment
  • Known syndromic/monogenic obesity
  • Blood disorders impacting HbA1c (e.g., anemia, hemoglobin variants)
  • Major systemic organ disease
  • History of bariatric surgery or currently planning bariatric surgery
  • Current pregnancy or currently planning pregnancy
  • Use of GnRH agonist, estrogen, or testosterone
