Clinical Trial Summary

This research study collects health-related information and blood samples to better understand how body composition, lifestyle habits, and diet influence meta-inflammatory monocytes (MiMos) in adolescents. The hypothesis of this study is that adolescents at risk for metabolic disease have enhanced MiMo related activities leading to insulin resistance.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Glucose (OGTT)	Plasma Glucose (mg/dL) will be measured prior to, and throughout, an Oral Glucose Tolerance Test (OGTT). Measurements will be taken at baseline (fasting) and 30, 60, 90 and 120 minutes after consumption of glucose dose	120 minutes
Primary	Insulin (OGTT)	Plasma Insulin (µU/mL) will be measured prior to, and throughout, an Oral Glucose Tolerance Test (OGTT). Measurements will be taken at baseline (fasting) and 30, 60, 90 and 120 minutes after consumption of glucose dose	120 minutes
Primary	Glucose (MMTT)	Plasma Glucose (mg/dL) will be measured prior to, and throughout, a Mixed Meal Tolerance Test (MMTT). Measurements will be taken at baseline (fasting) and 30, 60, 90, 120 and 180 minutes after consumption of high fat shake.	180 minutes
Primary	Insulin (MMTT)	Plasma Insulin (µU/mL) will be measured prior to, and throughout, a Mixed Meal Tolerance Test (MMTT). Measurements will be taken at baseline (fasting) and 30, 60, 90, 120 and 180 minutes after consumption of high fat shake.	180 minutes
Primary	Monocyte /macrophage populations by flow cytometry	Frequencies by flow cytometry. Measurements will be taken at baseline sample and 180 minutes after consumption of high fat shake	180 minutes
