Our previous study, performed on early postpartum women with GDM or with excessive gestational weight gain, revealed that the maternal serum FABP4 concentrations correlated positively with the lipid profile (i.e., total cholesterol, HDL, and LDL levels), and they also correlated negatively with HgbA1c concentrations in healthy puerperal mothers [18]. Here, FABP4 is linked to gestational diabetes.
