Study Finds Breastfeeding Not Protective Against Development of Allergies, Asthma

JAMA. 2007;298(14):1629. doi:10.1001/jama.298.14.1629

Breastfeeding appears to provide many health benefits to newborn infants, but reducing their risk for developing certain allergies or asthma is not one of them, according to findings by researchers from Canada and Belarus.

In a randomized controlled trial with an initial enrollment of 17 046 mother-infant pairs, the researchers found that 6.5 years after birth, children had the same risk for developing allergies or asthma whether or not they experienced prolonged or exclusive breastfeeding. The findings were published online by the British Medical Journal (Kramer MS et al. BMJ. doi:10.1136 /bmj.39304.464016.AE [published online ahead of print September 11, 2007]).
