Background: Human milk oligosaccharides (HMOs) are unconjugated glycans associated with infant health and development.
Objectives: To investigate the associations between HMO concentrations at 1 month and infant development throughout the first year of life.
Methods: A prospective cohort of Brazilian women between 18-40 years of age and their infants was studied from baseline (between 28-35 gestational weeks) and followed at 1 (n = 73), 6 (n = 51), and 12 months (n = 45).
