Table 4. Maternal BMI is Associated with Daily Infant Intakes of Human Milk Amino Acids Over the First 6 Months of Life.
Linear mixed-effects models (n = 169 subjects) included human milk amino acid intakes (μmol/kg/day) as the dependent variables and maternal BMI (kg/m2) at first visit as the fixed effect. Model covariates included: infant age, infant sex, maternal race, gestational weight gain, and breastfeeding status (exclusive or mixed). Asn = asparagine, C-C = cystine, His = histidine, Ile = isoleucine, Leu = leucine, Phe = phenylalanine, and Tyr = tyrosine.
