Brief Summary
Delayed clamping of the umbilical cord might prevent or slow the onset of iron deficiency by increasing the infant's iron endowment at birth. Compared with early clamping, a delay of around 2-3 min provides an additional 25-40 mL of blood per kg of bodyweight. The results of previous intervention studies on delayed clamping are mixed, and few followed up infants beyond the perinatal period. All longer follow up studies have been performed in low income countries. The main objectives, therefore, was to assess whether delayed cord clamping improves hematological and iron status at 4 respective 12 months of age in a large sample of full-term, Swedish infants. The investigators also choose to investigate if the timing of clamping the umbilical cord could affect rate of infections during the first four months of life and to assess the infants development at 4 and 12 months of age.

Outcome Measures
Primary Outcomes (1)
Do time for clamping the umbilical cord affect children's hemoglobin and iron status at 4 months of age?
Using mean cell volume (MCV), mean cell hemoglobin concentration (MCHC), reticulocyte hemoglobin, serum ferritin, transferrin saturation and soluble transferrin receptors to assess iron status
4 months of age (plus or minus three weeks)
Secondary Outcomes (11)
Do the time for clamping the umbilical cord affect children's hemoglobin and iron status at 12 months of age?
12 months of age (plus or minus one month)
Are the rates of successful umbilical arterial samples equal between the groups?
Immediately after birth (within 30 seconds)
Is there a difference in development as assessed by the Ages and Stages Questionnaire at 4 months of age?
4 months of age (plus or minus three weeks)
Do the time for umbilical cord clamping affect incidence of infections during the first four months of life?
4 months of age (plus or minus three weeks)
Is Reticulocyte hemoglobin a useful measure of iron stores at 2-3 days of age?
Mean 2 to 3 days of age (within 48-96 hours after birth)
- +6 more secondary outcomes
Study Arms (2)
Early cord clamping (ECC)
OTHEREarly cord clamping consisted of early (\< 10 s) clamping of the umbilical cord and obtaining blood gas samples after clamping.
Delayed cord clamping (DCC)
OTHERDelayed cord clamping consisted of delayed (\> 180 s) clamping of the umbilical cord and obtaining blood gas samples before clamping (within 30 seconds).
Interventions
The time passed after delivery until that the midwife stops circulation in the umbilical cord with a clamp.
