Abstract

Background: Exclusive breastfeeding (EBF) in the first six months of the life can significantly improve maternal and children health, and it is especially important in low- and middle-income countries. We aimed to determine the factors affecting EBF duration in a sample of Iranian infants.Methods: This prospective study was conducted between April 2012 and October 2014 in Fars, Iran.

Multivariable analysis was performed using Adaptive Lasso regression. P
