Sex-specific interactions and human milk (HM) composition. p-values are relative to the interaction between the two factors and HM composition (i.e., infant sex, birth-mode and milk protein). All the graphs show that maternal factors ((A) basic education, (B) gestational diabetes, (C) birth-mode and (D) mother’s occupation during pregnancy) is associated with the concentration of HM components in a sex-specific manner. Graphs represent Mean and CIs. Mothers in the Sick Leave group were only n = 3 (two males and one female). IGF1 = Insulin-like growth factor 1, cGP = cyclic-Glycine-Proline, IGF1cGP = IGF1/cGP ratio.
