Maternal-Cord Blood Vitamin D Correlations Vary by Maternal Levels

Table 1

Descriptive information for 25(OH)D levels in the 241 maternal-child pairs. Values are given in ng/mL.

	Mean	SD	Median	Minimum	Maximum	Number below lowest detectable limit
Prenatal	23.6	11.9	22.7	2.5	64.9	4.98%
Cord blood	10.9	7.4	10.5	2.5	47.5	24.9%
Child is Black ()
Prenatal	20.1	10.3	19.8	2.5	49.9	6.9%
Cord blood	9.1	6.6	8.5	2.5	47.5	30.2%
Child is White ()
Prenatal	32.9	10.8	34.1	13.1	64.9	0
Cord blood	15.6	7.2	15.6	2.5	28.7	10.6%

2.5 ng/mL is assigned when the 25(OH)D value is less than the lowest detectable value of 5 ng/mL.
