Effect of timing of umbilical cord clamping on iron status in Mexican infants: a randomised controlled trial

Background Delayed clamping of the umbilical cord increases the infant's iron endowment at birth and haemoglobin concentration at 2 months of age. We aimed to assess whether a 2-minute delay in the clamping of the umbilical cord of normal-weight, full-term infants improved iron and haematological status up to 6 months of age. Methods 476 mother-infant pairs were recruited at a large obstetrics hospital in Mexico City, Mexico, randomly assigned...
