Chemicals in common consumer products may play a role in pre-term births
Date:7/6/2009

re commonly used compounds in plastics, personal care products, home furnishings (vinyl flooring, carpeting, paints, etc.) and many other consumer and industrial products. The toxicity varies by specific phthalates or their breakdown products, but past studies show that several phthalates cause reproductive and developmental toxicity in animals.

A couple of human studies have reported associations between phthalates and gestational age, but this is the first known study to look at the relationship between phthalates and premature births, Meeker says.

"We looked at these commonly used compounds found in consumer products based on the growing amount of animal toxicity data and since national human data show that a large proportion of the population are unknowingly exposed," Meeker said. "One of the problems for consumers is that you don't know exactly which products contain phthalates because the products do not have to be labeled accordingly."

Meeker says the U-M study is a stepping stone to larger and more detailed studies examining the role of phthalates and premature births. The researchers hope to examine a larger population of pregnant women to corroborate these initial study findings, and conduct experimental lab studies to further explore the biological mechanisms of how phthalates work in the body.
