Vitamin D Status in Women with Gestational Diabetes Mellitus during Pregnancy and Postpartum

Table 2

Correlations between 25(OH)D levels and selected anthropometric and biochemical parameters.

Parameters	Midgestational 25(OH)D levels		Postpartum 25(OH)D levels
	Pregestational BMI	−0.35	0.002	−0.25	0.030
Midgestational BMI	−0.30	0.008	−0.23	0.049
FPG	−0.36	0.001	−0.18	NS
1 hr after load glucose	−0.14	NS	−0.05	NS
2 hr after load glucose	−0.15	NS	−0.43	0.005
Weight gain during pregnancy	0.35	0.002	0.15	NS
Offspring birth weight	0.01	NS	−0.04	NS

Correlations were assessed using Spearman’s correlation coefficient. The midgestational 25(OH)D levels were correlated with results of oGTT provided in the midtrimester, and the postpartum 25(OH)D levels were correlated with results of oGTT provided 6 weeks to 12 months postpartum.
