Higher levels of fluoride in drinking water appear to be associated with an increased risk for hypothyroidism in a new study from England, raising concerns about the validity of community fluoridation of water as a safe public-health measure.
In particular, when a comparison was drawn between the West Midlands, a completely fluoridated area (0.7 mg/L or more) and Greater Manchester, a nonfluoridated area (0.3 mg/L or less), nearly twice the risk for hypothyroidism was detected in the West Midlands.
The report, published online February 24 in the Journal of Epidemiology and Community Health, describes the first population-level study investigating the association between fluoride levels in drinking water and hypothyroidism.
