Re: Effect of delayed versus early umbilical cord clamping on neonatal outcomes and iron status at 4 months: a randomised controlled trial

Dr Griffiths concern regarding breast feeding rates are important, as breast feeding is known to be associated with several positive effects. In the paper, we report data regarding how many children that had started breast feeding at 1 and 6 hours of age, and the proportions of infants breastfeeding, exclusively or partially, at four months of age. We could not demonstrate any significant differences between groups at any of these time points.
At four months: 56% infants were exclusively breast fed in the delayed cord clamping group, and 51% in the early group. This can be compared with data from the Swedish "National Board of Health and Welfare" (1) that reports that 53% of all children born in 2009 were exclusively breast fed at four months of age (in the region of Halland, where the study was performed, the rate was 53.6%).
In summary, we can not find any indications that breast feeding rates were affected by either delayed or early cord clamping.
