Neonatal vitamin D status in relation to autism spectrum disorder and developmental delay in the CHARGE case-control study.

ABSTRACT: Vitamin D appears essential for normal neurodevelopment and cognitive and behavioral function. We examined neonatal vitamin D in relation to the child's later diagnosis of autism spectrum disorder (ASD) or developmental delay (DD). Children aged 24-60 months enrolled in the population-based CHARGE case-control study were evaluated clinically for ASD (n = 357), DD (n = 134), or typical development (TD, n = 234) at the MIND Institute (Sacramento, CA) using standardized assessments. Total 25-hydroxyvitamin D (25[OH]D) was measured using sensitive isotope dilution liquid chromatography-tandem mass spectrometry in archived dried blood spots collected for the California Department of Public Health's Newborn Screening Program. Multinomial logistic regression was used to calculate ORs as measures
