Epidemiological studies of multiple cohorts suggest an increased risk for obesity, cardiovascular disease-related death and type 2 diabetes in low birth weight infants. However, the molecular mechanisms underlying developmental programming of childhood obesity remain poorly understood. Alterations in DNA methylation during fetal life have been proposed to be one of the mechanisms that regulate this phenotype. Here, the investigators address major questions about early childhood obesity programming by studying purified subpopulations of CD3+ T-cells from intrauterine growth restricted (IUGR) newborns who have an increased risk for obesity and other metabolic disorders in adult life. The investigators will correlate altered CD3+ T-cell DNA methylation profiles in cord and peripheral blood samples and functional changes in CD3+ T-cells with adiposity in childhood.
