Another nail in the coffin of Fluoridation. New study hard on the heels of the UK University fluoridation-thyroid study shows fluoridation correlates with an increase in the number of children with ADHD (attention deficit and hyperactivity disorder).
The study entitled, “Exposure to fluoridated water and attention deficit hyperactivity disorder prevalence among children and adolescents in the United States”: was published in the journal Environmental Health on Friday 27th February 2015.
According to the authors:
“State prevalence of artificial water fluoridation in 1992 significantly positively predicted state prevalence of ADHD in 2003, 2007 and 2011, even after controlling for socioeconomic status.
A multivariate regression analysis showed that after socioeconomic status was controlled each 1% increase in artificial fluoridation prevalence in 1992 was associated with approximately 67,000 to 131,000 additional ADHD diagnoses from 2003 to 2011. Overall state water fluoridation prevalence (not distinguishing between fluoridation types) was also significantly positively correlated with state prevalence of ADHD for all but one year examined.
Conclusions: Parents reported higher rates of medically-diagnosed ADHD in their children in states in which a greater proportion of people receive fluoridated water from public water supplies.”
This is the first study to examine the relationship between exposure to fluoridated water and ADHD prevalence. ADHD is a common childhood disorder. Symptoms include difficulty paying attention, controlling behavior, and hyperactivity.
Researchers, Malin and Till, conclude that, even after controlling for socio-economic-status, their findings suggest that fluoridated water may be an environmental risk factor for ADHD.
They write, fluoride “has received virtually no attention in the ADHD literature, [even though], there is a burgeoning body of human and animal research indirectly suggesting that it may contribute to the disorder’s onset.”
ADHD/fluoride study comes on the heels of a British study linking fluoride to thyroid disease.
Malin and Till write “exposure to fluoridated water may contribute to ADHD via suppression of the thyroid gland.”
Paul Connett, PhD, FAN Executive Director says “We’ve been falsely assured that the science is settled on fluoridation safety. But studies such as this one were never done before. What else have they failed to research? What’s worse is that government agencies dismiss research that hurts fluoridation rather than protect the citizens whose health is entrusted to them.”
Researchers Malin and Till explain that children and adults living in fluoridated communities (0.7 – 1.2 mg/L) actually received up to 3.6 mg and 6.6 mg of fluoride per day, respectively from all sources, including water, food and dental products.
They write “Fluoride can readily cross the placenta, accumulate in the infant brain and easily exert neurotoxic effects…Such changes can adversely affect arousal and attention, pain tolerance, and learning and memory, respectively.”
“Importantly, among children who were exposed environmentally to water fluoridated at 1.2 – 3 mg/L (slightly above the US recommended level), increased urinary fluoride concentrations were associated with slower reaction time and poorer visuospatial organization that could interfere with attention, and reading and writing respectively,” they write.
Connett adds, “With fluoride linked to lower IQ, and ADHD in children and hypothyroidism in adults, it is reckless to continue fluoridation.”
