Outcome Measures

Primary Outcomes (2)

  • Hematologic status at 6 months of age

  • Iron status at 6 months of age

Secondary Outcomes (3)

  • Maternal report of clinical jaundice at 3 and 14 days of age

  • Newborn hematocrit at 7 hours of age

  • Estimated maternal bleeding at delivery

Study Arms (2)

Early umbilical cord clamping (control)

NO INTERVENTION

Umbilical cord was clamped immediately, or as close as possible, after delivery of the infant's shoulders. (This was standard practice in the study hospital, thus it served as the "control" group).

Delayed umbilical cord clamping

EXPERIMENTAL

Umbilical cord was clamped at 2 minutes after delivery of the infant's shoulder's with the infant held at the level of the mother's uterus.

Procedure: Delayed umbilical cord clamping

Interventions

Delayed umbilical cord clamping
