Correlations between 25(OH)D levels and selected anthropometric and biochemical parameters.
| Parameters | Midgestational 25(OH)D levels | Postpartum 25(OH)D levels | ||
|---|---|---|---|---|
| r | P | r | P | |
| 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.
