Potential interaction between timing of infant complementary feeding and breastfeeding duration in determination of early childhood gut microbiota composition and BMI.

ABSTRACT:

Background

Introducing complementary foods other than breastmilk or formula acutely changes the infant gut microbiota composition. However, it is unknown whether the timing of introduction to complementary foods (early vs. late) in infancy is associated with early childhood gut microbiota and BMI, and if these associations depend on breastfeeding duration.

Objective

Our primary objective was to investigate whether timing of infant complentary feeding with solid foods is associated with early childhood gut microbiota composition and BMI-z, and whether these associations differ by duration of breastfeeding.

Methods

We used data from a Canadian pre-birth cohort followed till age 5 years. We examined timing of introduction to solid foods with the gut microbiota, determine
