Table 7.

Unadjusted and adjusted associations between ASD children with and without intellectual disability (ID) and neonatal dried blood spot total 25-hydroxyvitamin D [25(OH)D] compared to TD children.

TD
(n = 234)		 ASD with ID
(n = 243)		 ASD without ID
(n = 113)		 ASD with ID vs. TD
OR (95% CI)		 ASD without ID vs. TD
OR (95% CI)
Crude model 82.7 (39.3) 77.5 (36.2) 85.9 (39.3) 0.91 (0.81–1.03) 1.05 (0.91–1.21)
Adjusted Model1 0.93 (0.82–1.04) 1.06 (0.92–1.23)

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

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

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