NCT06007404

Brief 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 Measures

Primary Outcomes (5)

  • 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

  • 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

  • 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

  • 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

  • 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

Secondary Outcomes (2)

  • Free fatty acids (MMTT)

    180 minutes

  • Triglycerides (MMTT)

Sampling MethodNon-Probability Sample
Study Population

Participants may be recruited from a variety of sites including University of Michigan clinical sites, non-University of Michigan clinical sites, local communities and schools throughout Southeast Michigan, and the University of Michigan campus.

You may qualify if:

  • Between 14 and 18 years of age
  • Tanner stage 4 or 5 (mature adult stage of puberty)
  • Normal weight (BMI ≥ 5th percentile \& \< 85th percentile), overweight (BMI \> 86th percentile) \& \< 94th percentile), obese weight (BMI percentile ≥ 95th percentile), and/or pre-diabetes (HbA1c \> 5.7%)
  • For Type 2 Diabetes cohort, diagnosis of Type 2 Diabetes

You may not qualify if:

  • Currently pregnant
  • Use medications known to affect glucose metabolism (immunosuppressive medications, cancer medications, or high dose steroids), unless prescribed for Type 2 Diabetes management
  • Prior diagnosis of autoimmune disease, cancer, or a cognitive or perceptual disability that would inhibit following directions of study staff
  • Allergies or intolerance to milk, soy, or palm oil
