Association of maternal vitamin D status in pregnancy (independent variable) with SGA and pre-term risk (dependent variables) (n=910)¹

	Vitamin D Deficiency (<50 nmol/L)	Vitamin D Insufficiency (≥50 and <75 nmol/L)	Vitamin D Sufficiency (>75 nmol/L)
	n=120	n=241	n=549

	OR (95%CI)	OR (95%CI)	OR (95%CI)
SGA²	1.00 (0.56, 1.79)	1.08 (0.50, 2.34)	Ref
Pre-term²	1.16 (0.64, 2.11)	1.06 (0.48, 2.38)	Ref

Adjusted for maternal ethnicity, education, smoking during pregnancy, age, pregnancy BMI, total maternal energy intake, infant birth order and infant gender

No statistically significant differences were seen between maternal vitamin D deficiency status with SGA and pre-term outcomes.
