Breastfeeding Protects Against Asthma up to 6 Years of Age

This prospective birth cohort from New Zealand included 1,000 infants. Information about wheezing and current asthma was collected at 2, 3, 4, 5, and 6 years.

Each month of exclusive breastfeeding was associated with reductions in current asthma from 2 to 6 years. Current asthma at 2, 3, and 4 years was also reduced by each month of any breastfeeding.

In atopic children, exclusive breastfeeding for ≥3 months reduced current asthma at ages 4, 5, and 6 by 62%, 55%, and 59%, respectively.

The authors concluded that breastfeeding, particularly exclusive breastfeeding, protects against current asthma up to 6 years. The degree of protection beyond 3 years was more pronounced in atopic children.

  1. Why is it, then, that the most severely asthmatic child I know was breastfed until 2 years of age?
