Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate the longitudinal test performance of an array of conventional biomarkers of glycemia, including Hemoglobin A1c (HbA1c), and novel metabolomic biomarkers for identifying progression of glucose tolerance (normal to prediabetes or prediabetes to diabetes) in an overweight and obese pediatric cohort.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group 1: Overweight or Obese Group (visits #1-4)

Children and young adults who are 8 to 22 years of age, who have risk factors for diabetes such as being overweight. Overweight or obese, as defined by a BMI ≥ 85th percentile \& \<95th percentile or BMI ≥ 95th percentile, respectively. Study participants cannot be pregnant or currently take medications known to affect glucose metabolism including, metformin, oral steroids, sulfonylureas, and insulin.

No interventions assigned to this group

Group 2: Overweight or Obese Group (visits #3-4)

Children and young adults who are 8 to 22 years of age, who have risk factors for diabetes such as being overweight, or children and young adults who previously participated in the study (completed visits #1-2 in previous study phase). Overweight or obese, as defined by a BMI ≥ 85th percentile \& \<95th percentile or BMI ≥ 95th percentile, respectively. Study participants cannot be pregnant or currently take medications known to affect glucose metabolism including, metformin, oral steroids, sulfonylureas, and insulin.

No interventions assigned to this group

Group 3: Normal Weight Control Group

Children and adolescents who are 8 to 17 years of age, who have do not have risk factors for diabetes such as being overweight or a history of type 2 diabetes in the family. Healthy weight, as defined by a BMI ≥ 5th percentile \& \< 85th percentile. Study participants cannot be pregnant or currently take medications known to affect glucose metabolism including, metformin, oral steroids, sulfonylureas, and insulin.

No interventions assigned to this group
