STUDY PROMPTS CALL FOR LOWER FLUORIDE CONSUMPTION BY PREGNANT WOMEN
The world’s premier pediatric journal has published a new government-funded study confirming our worst fears, linking exposure to “optimally” fluoridated water during pregnancy to lowered IQ for the child.
You can repair a cavity, but you cannot repair a child’s brain.
The American Medical Association’s journal on pediatrics (JAMA Pediatrics) has published the second U.S. Government-funded study linking low-levels of fluoride exposure during fetal development to cognitive impairment. The observational study, entitled Association Between Maternal Fluoride Exposure During Pregnancy and IQ Scores in Offspring in Canada, was led by a team at York University in Ontario, Canada and looked at 512 mother-child pairs from six major Canadian cities. It was funded by the Canadian government and the U.S. National Institute of Environmental Health Science.
The scientists assessed fluoride exposure two ways. They measured fluoride in women’s urine samples during pregnancy. They also calculated fluoride consumption based on how much is in a city’s water supply and how much women recalled drinking. They found that a 1 mg per liter increase in concentration of fluoride in mothers’ urine was associated with a 4.5 point decrease in IQ among boys, though not girls. When the researchers measured fluoride exposure by examining the women’s fluid intake, they found lower IQs in both boys and girls: A 1 mg increase per day was associated with a 3.7-point IQ deficit among both genders.
Making the publication of this study even more impactful is that it is accompanied by an editor’s note, a podcast featuring the journal’s editors, and an editorial from world-renowned neurotoxicity expert Dr. David Bellinger. This reaction by the JAMA editors shows just how important the study is, as most studies in their journal don’t receive this treatment.
For the first time in his career, the editor of Pediatrics included an editorial note, knowing fluoridation proponents would attack the study without justification. He noted the study’s rigor, triple-checking of the data, and definitive nature of the evidence:
This decision to publish this article was not easy. Given the nature of the findings and their potential implications, we subjected it to additional scrutiny for its methods and the presentation of its findings. The mission of the journal is to ensure that child health is optimized by bringing the best available evidence to the fore. Publishing it serves as testament to the fact that JAMA Pediatrics is committed to disseminating the best science based entirely on the rigor of the methods and the soundness of the hypotheses tested, regardless of how contentious the results may be. That said, scientific inquiry is an iterative process. It is rare that a single study provides definitive evidence. This study is neither the first, nor will it be the last, to test the association between prenatal fluoride exposure and cognitive development. We hope that purveyors and consumers of these findings are mindful of that as the implications of this study are debated in the public arena.
