Infant weight gain, duration of exclusive breast-feeding and childhood BMI – two similar follow-up cohorts
Abstract Objective To describe the association between duration of exclusive breast-feeding (EBF), weight gain in infancy and childhood BMI in two populations with a long duration of EBF. Design Cohort study with follow-up in childhood. Breast-feeding status was reported monthly during infancy. Weig...

Conclusions Although duration of EBF was not associated with childhood BMI in the present study it may modulate growth rate in infancy, which is related to childhood BMI.
