The authors reported lower adiponectin levels in the women with pGDM 1.57 years postdelivery, while it is also of interest that the levels of adiponectin were progressively lower, the postpartum glucose tolerance values ranging from normality to impaired glucose tolerance and finally Diabetes Mellitus after GDM (P for linearity = 0.006). This evidence concerns the gene ADIPOQ and Impaired glucose tolerance.
