NCT01967849

Brief Summary

The purpose of this study is to determine the prevalence of impaired glucose (carbohydrate) tolerance in lean children with a family history of diabetes and in overweight/obese children with or without a family history of diabetes mellitus.

Outcome Measures

Primary Outcomes (1)

  • Glucose Tolerance

    Glucose tolerance status as determined by 3 hour oral glucose tolerance test

    Baseline measurements

Secondary Outcomes (1)

  • Insulin resistance

    Completed at baseline measurement

Other Outcomes (1)

  • Gene Expression

    Completed at baseline measurement

Study Arms (2)

Obese/overweight chldren/adolescents

Obese or overweight children and adolescents between ages 7-21 that are at risk for developing type 2 diabetes will undergo an Oral Glucose Tolerance test (OGTT) to asses glucose status.

Diagnostic Test: Oral Glucose tolerance test

Lean children/adolescents

Lean children/adolescents between the ages of 7-21. This cohort should have family members that have type 2 diabetes or was the result of a gestational diabetes pregnancy. They will undergo an Oral Glucose Tolerance Test to assess glucose status.

Diagnostic Test: Oral Glucose tolerance test

Study Population

Primarily these patients are recruited from Yale Pediatric Endocrinology Clinic or are siblings of patients.

You may qualify if:

  • ages 7-21
  • family history of type 2 diabetes mellitus

You may not qualify if:

  • Children will be excluded if they have previously been treated for another endocrinopathy or are on any chronic medications that are known to alter glucose or insulin metabolism, such as oral steroids, or certain psychiatric medications, such as Xeleca, Lithium and Paxil.
  • Lean (not overweight or obese) will be defined as a body mass index (BMI) (kg/m2) less than the 85th percentile specific for age and gender, overweight will be defined as a BMI between the 85th and 95th percentiles, and obesity will be defined as a BMI greater than the 95th percentile.
  • Children will be excluded from participating in the genetic analysis if they are treated oral glucocorticoids or antirejection or chemotherapy (e.g. tacrolimus, Lasparaginase.
