Prospective associations of breastfeeding parents' postpartum dietary intake with infant gut microbiome at 6 months in the Pregnancy Eating Attributes Study.

ABSTRACT:

Background

Oligosaccharides in breast milk facilitate colonization of infant gut microbiota that reduce the risk of metabolic disorders. Although diet influences human milk composition, no study to date has examined the association of breastfeeding parents' dietary intake, exclusively during the postpartum period, with infant gastrointestinal microbiome.

Objective

To examine the relationship of postpartum diet quality of the breastfeeding parent, as measured by Healthy Eating Index-2015 (HEI-2015), with 6-month infant gut microbiota.

Design

A secondary data analysis of a prospective pregnancy cohort participating in the Pregnancy Eating Attributes Study in North Carolina.

Participants/settings

Of 458 participants enrolled from November 2014 through October 2016
