RESUMO
ABSTRACT Objectives The objectives were to evaluate the relation between fetal anthropometric parameters and cord blood concentration of adiponectin and high sensitivity C-reactive protein (hs-CRP). Subjects and methods: A total of 104 pregnant women (52 with gestational diabetes mellitus [GDM], 52 with normal glucose tolerance (NGT) participated. Venous cord blood samples were obtained at delivery, centrifuged and the plasma was stored at -20°C. The samples were assessed for adiponectin and hs-CRP using the ELISA method. Statistical analysis was done using SPSS software. Results The adiponectin concentration was higher in the GDM group than in the NGT group (11.05 ± 4.1 µg/mL in GDM vs. 5.34 ± 2.63 µg/mL in NGT, p < 0.001). GDM was also higher in neonates delivered at later gestational ages (p < 0.001, Pearson correlation = 0.59). There was a positive correlation between cord blood adiponectin and birth weight in the GDM group (p < 0.001, Pearson correlation = 0.619) but not in the NGT group. There was no significant correlation between adiponectin and infant length or head circumference. There was also no significant difference in cord blood hs-CRP concentration between groups. No relation was found between hs-CRP and newborn anthropometric parameters. Conclusion In the GDM group, adiponectin concentration was considerably higher and had a positive correlation with the ponderal index and birth weight which was not found in the NGT group.
