Brief Summary

The molecular mechanisms underlying developmental programming of childhood obesity remain poorly understood. Here, the investigators address major questions about early childhood obesity programming by studying CD3+ T-cells from intrauterine growth restricted (IUGR) newborns who have an increased risk for obesity and other metabolic disorders in adult life.

Conditions

Childhood Obesity; Epigenetics

Outcome Measures

Primary Outcomes (3)

• Growth velocity

  Change in growth velocity based on DNA methylation marks and functional profiles of CD3+ T-cells

  Until 24 months of age

• DNA methylation of CD3+ T-cells

  Change in DNA methylation of CD3+ T-cells in the first 24 months of life in IUGR infants

  At birth and 24 months of age

• T-cell function

  Change in T-cell function in the first 24 months of life in IUGR infants

  At birth, 12 and 24 months of age

Study Arms (2)

IUGR infants

Intrauterine growth restricted infants will be enrolled. There are no interventions.

AGA infants

• Deliver a single healthy live term infant at ≥37 weeks' gestational age (GA)
• All patients must be informed of the investigational nature of this study and must sign and give written informed consent in accordance with institutional and federal guidelines

You may not qualify if:

• Multiple gestation
• Maternal depression
• Maternal renal disease
• History of maternal smoking in the 2nd and 3rd trimester of pregnancy
• Maternal gestational diabetes / Type 2 Diabetes (T2D)
• Preterm birth (less than 37 weeks' gestation)
