Gestational Exposures to Phthalates and Folic Acid, and Autistic Traits in Canadian Children.

The relationship between gestational phthalates and autistic traits in 3- to 4-y-old Canadian children. We also investigated potential effect modification by sex and folic acid supplementation.

Higher gestational concentrations of some phthalate metabolites were associated with higher scores of autistic traits as measured by the SRS-2 in boys, but not girls; these small size effects were mitigated by first trimester-of-pregnancy folic acid supplementation.

Phthalates (pronounced “thah-lates”) are chemical plasticizers that have been widely used since the 1950s to soften plastics that would otherwise be brittle and crack when bent. Phthalates are found in an amazing array of products. In personal care items, they’re used to help lubricate other substances, help lotions penetrate and soften the skin, and help fragrances last longer. They’re also used in toys, electronics (such as personal computers), car-care products, insecticides, and many household products, including adhesives, plastic wrap, plastic containers, flooring, furniture, wallpaper, shower curtains, and other things made of vinyl or PVC.
