NCT01439048

Brief Summary

The purpose of this study is to determine if changes in specific gene products in the placenta or cord/infant blood affect a baby's birth weight, increase the risk of premature birth, or increase the risk of developing diseases of prematurity. We would also like to characterize whether placental epigenetic changes or placental markers of environmental exposures are associated with premature birth.

Outcome Measures

Primary Outcomes (1)

  • Comparisons of placental gene expression and cord blood immune markers

    Placental gene expression and cord-blood immune markers/function will be compared between 50 term infants and 150 preterm infants. Further, among preterm infants it will be determined whether certain patterns of gene expression and immune marker distribution are associated with specific diseases/condition and growth outcomes. Similarly, epigenetic changes in the immune genes and markers of environmental exposure will be compared between preterm infants and term infants. Associations between environment exposures and epigenetic changes and diseases of prematurity will also be determined.
