Serum Adiponectin in Women with Gestational Diabetes

Adiponectin is an adipose tissue adipokin that may contribute to obesity and insulin resistantance. The aim of this study was to evaluate the associations between serum concentrations of adiponectin and insulin resistance in gestational diabetes (GDM). Serum adiponectin levels، fasting blood sugar (FBS)، glycated hemoglobin (HbA1C)، insulin levels and blood lipids were measured in 66 women with GDM and 70 pregnant women without GDM. The associations between serum concentrations of adiponectin and insulin resistance were evaluated using the homeostasis model assessment of insulin resistance (HOMA–IR) and quantitative insulin sensitivity check index (QUICKI). There were statistically significant between-group differences in FBS، HbA1C and HOMA–IR. Adiponectin concentrations were not significantly different in GDM women in comparison with the control group. However، GDM women above the age of 30 have significantly lower adiponectin concentrations than those without GDM. Adiponectin was positively associated with QUICKI (r = 0. 268، P < 0. 03) and inversely related to HOMA–IR (r = 0. 238، P < 0. 05). Adiponectin is significantly decreased in older women with GDM. Deficiency of adiponectin may correlate with insulin resistance in GDM.
