Relationships among leptin concentrations incolostrum and mature milk and maternal serum leptin, cortisol, insulin and thyroxine concentrations. In the cross-sectional component of the study, leptin concentrations in breast milk samples collected at 1–3 days [colostrum (Figure 2 A, B and C)] or at 15–180 days [mature milk (Figure 2 D, E and F)] were plotted against the maternal serum concentrations of leptin (A and D), cortisol (B), insulin (E) and thyroxine (C and F).
