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.

Demographic information from mothers and infants, medical and drug history, and pregnancy related factors were compared between the two groups. Multivariable analysis was performed using Adaptive Lasso regression. P
