Association between History of Prolonged Exclusive Breast-Feeding and the Lung Function Indices in Childhood.

Although the propitious effects of breastfeeding on children's health are indisputable, the impact of exclusive breastfeeding on the lung function later in life remains controversial. Our objective was to explore the possible associations between breastfeeding and the lung function of children who were exclusively breastfed for an extensive period of time. This was a cross-sectional study of children who were exclusively breastfed for more than 12 months.
