“Association Between Maternal Exposure to Magnetic Field NIR During Pregnancy and Risk of Attention-Deficit/Hyperactivity Disorder in Offspring in a Longitudinal Birth Cohort,” JAMA Network Open, March 24, 2020. See also: “Notice of Retraction and Replacement.”

“Consistent with the emerging literature, this study suggests that in utero exposure to high levels of MF non-onizing radiation was associated with an increased risk of ADHD, especially ADHD with immune-related comorbidity.” The most recent study by De-Kun Li of Kaiser Permanente. Note: “high” is defined as a 24-hour exposure of ≥1.5 mG (90th percentile). According to a 1998 survey, >40% of Americans are exposed to >1 mG. And the ICNIRP 2010 guidelines allow the general public to be exposed up to 2,000 mG.

A mother's exposure to weak power-frequency magnetic fields during pregnancy substantially increases the chances her child will develop asthma, according to a new study by De-Kun Li and coworkers at Kaiser Permanente in Oakland, CA. An average magnetic field exposure of just 2 mG (0.2 µT) during pregnancy more than triples the child's risk of getting asthma by the age of 13, they report in a paper released today by the Archives of Pediatrics & Adolescent Medicine, a publication of the American Medical Association (AMA).

Editors and reviewers at Epidemiology thought long and hard before publishing the new paper suggesting that a child's behavioral problems can be traced, at least in part, to the mother's use of a cell phone use during pregnancy (see our May 14 post). This comes across in an editorial by David Savitz that appears the same issue (July) as the paper.

The study is "a nearly perfect recipe for 'inflammatory epidemiology'," acknowledged Savitz, an editor at the journal who has long been involved with EMF research. But, he went on, "reviewers and editors believe that these findings are worth consideration by the scientific community.
