- Hypothesis: male autism risk increased if placental virus and low vitamin D – Feb 2018
- Women who had supplemented with any vitamins were 6 X less likely to have autistic offspring – Jan 2018
- A good Vitamin D Receptor (or perhaps more vitamin D) protects against lead during pregnancy
- Autism rate cut in half when multivitamins (including vitamin D) used during pregnancy – Oct 2017

BACKGROUND:
There is growing interest in linking vitamin D deficiency with autism spectrum disorders (ASDs). The association between vitamin D deficiency during gestation, a critical period in neurodevelopment, and ASD is not well understood.
AIMS:
To determine the association between gestational vitamin D status and ASD.
METHOD:
Based on a birth cohort (n=4334), we examined the association between 25-hydroxyvitamin D (25OHD), assessed from both maternal mid-gestation sera and neonatal sera, and ASD (defined by clinical records; n=68 cases).
RESULTS:
Individuals in the 25OHD-deficient group at mid-gestation had more than twofold increased risk of ASD (odds ratio (OR)=2.42, 95% confidence interval (CI) 1.09 to 5.07, P=0.03) compared with the sufficient group. The findings persisted in analyses including children of European ethnicity only.
CONCLUSIONS:
Mid-gestational vitamin D deficiency was associated with an increased risk of ASD. Because gestational vitamin D deficiency is readily preventable with safe, inexpensive and readily available supplementation, this risk factor warrants closer scrutiny.
