The Journal of the American Medical Association, Pediatrics published a paper today detailing an association between consuming fluoride in drinking water during pregnancy and decreased IQ in young children. The most cited finding is, "A 1-mg increase in fluoride intake was associated with a 3.66 … lower FSIQ score among boys and girls.”

CWWA’s drinking water quality committee will be discussing at our next meeting. The implications are difficult to determine without a closer examination of the specific scale used to measure IQ and the actual fluoride exposure.
