Table 8.

Unadjusted and adjusted associations between genetic syndrome and dried blood spot total 25-hydroxyvitamin D [25(OH)D] in syndromic subgroups of children with DD compared to TD children.

	TD (n = 234)	Down Syndrome (n = 29)	Other Syndrome (n = 18)	No syndrome (n = 86)	Down Syndrome vs. TD OR (95% CI)	Other Syndrome vs. TD OR (95% CI)	No syndrome vs. TD OR (95% CI)
Dried blood spot 25(OH)D (nmol/L)
	Mean (SD)
Crude model	82.7 (39.3)	67.0 (41.9)	76.0 (25.3)	75.1 (38.5)	0.74 (0.56–0.99)^*	0.89 (0.65–1.23)	0.88 (0.74–1.04)
Adjusted Model¹					0.79 (0.58–1.06)	0.99 (0.71–1.38)	0.97 (0.81–1.15)

Note: OR = odds ratio; CI = confidence interval; OR are reported for 25 units increase in 25(OH)D.

p < .05. This analysis is restricted to the DD and TD groups.

Adjusted for maternal education, pre-pregnancy body mass index; in the adjusted model, data on some covariates are missing on 27 children.
