Correlation between Maternal Vitamin D and Thyroid Function in Pregnancy with Maternal and Neonatal Outcomes: A Cross-Sectional Study

Table 3

Neonatal outcomes and maternal serum vitamin D.

Maternal serum vitamin D	C-section, n (%)	Neonatal weight (gr)	Height (cm)	Head circumference (cm)	Gestational age of birth (weeks)	Apgar (10 points)	Bilirubin level (mg/dl)
Severe vitamin D deficiency, n = 1	0 (0)	2550	47	34	36	9	6
Moderate vitamin D deficiency, n = 18	4 (22.2)	3323.33 ± 427.76	51.83 ± 2.5	33.81 ± 1.22	37.5 ± 1.04	9 ± 0	6.78 ± 0.73
Mild vitamin D deficiency, n = 11	5 (27.77)	3204.55 ± 346.74	51.18 ± 2.99	33.83 ± 1.47	36.91 ± 2.3	9 ± 0	7.45 ± 1.13
Vitamin D sufficient, n = 36	15 (41.66)	3160.56 ± 325.51	51.97 ± 2.95	33.17 ± 1.65	37 ± 1.37	9 ± 0	7.34 ± 1.45

A value of less than 0.05 is considered significant. Maternal vitamin D status based on serum vitamin D: severe vitamin D deficiency, serum 25OHD levels ≤ 8 ng/ml; moderate vitamin D deficiency, serum 25OHD levels from 8 ng/ml to 15 ng/ml; and mild vitamin D deficiency, serum 25OHD levels from 15 ng/ml to ≤20 ng/ml. Neonatal outcomes: birth weight (gram), height (cm), Apgar (10 points), gestational age (weeks), and serum bilirubin (mg/dl).
