A new study from The University of Texas Health Science Center at San Antonio found that mothers with chemical intolerances are two to three times more likely than other women to have a child with autism spectrum disorder (ASD) or attention deficit hyperactivity disorder (ADHD).
The medical study was published in the July-August 2015 issue of the Journal of the American Board of Family Medicine.
People who are chemically intolerant often have serious reactions to common chemicals and some become too sick to carry out routine functions. Chemical intolerance affects about 10 percent to 30 percent of the U.S. population. Developmental disorders such as autism and attention-deficit disorder affect one in six children in the United States.
The study was based on maternal responses to the Quick Environmental Exposure and Sensitivity Inventory, or QEESI, a 50-question survey used by physicians worldwide to diagnose chemical intolerance.
The authors recommend that all mothers and pregnant women adopt preventive measures to avoid potentially harmful chemicals. Preventive measures include avoiding exposure to pesticides, solvents, combustion products, and chemicals used during construction and remodeling.
