ABSTRACT
The main purpose was to determine the abundance of dominant phyla, Bifidobacterium spp., and Lactobacillus in breast milk of obese mothers versus normal-weights in fourth month of lactation in Iranian population. Sixty health women at the fourth month of breastfeeding, aged 18-40 years, were included and categorized based on body mass index (BMI) to the obese (BMI ≥ 30 kg/m2) and normal-weights (18.5 ≤ BMI ≤ 24.9). Bacterial DNA was extracted and qPCR of the 16S region was performed after human milk donation in a sterile condition. A multiple linear mixed model was used to determine the effective factors on the phyla population. Bifidobacterium spp. was significantly higher in milk of normal-weight group than the obese. The current weight showed a significant effect on the Actinobacteria abundance in milk. The Bacteroidetes and Firmicutes were significantly lower in mother's milk with cesarean section (p = 0.04). Pre-pregnancy obesity decreased the Firmicutes and Lactobacillus abundance in maternal milk (p = 0.04 and p = 0.01). The Actinobacteria and Bifidobacterium spp. showed a significant effect on infant's height (p = 0.008 and p = 0.04). The maternal current and pre-pregnancy weight showed an important effect on abundance of Actinobacteria and Bifidobacterium spp., as the good phyla and genus in milk which are associated with the infant's height.
