WHAT THE RESEARCH FOUND<\/h3>\n\n\n\n

An ecological design was used to examine if states with more widespread water fluoridation would have higher ADHD prevalence. State-based ADHD prevalence estimates (2003, 2007, 2011) and fluoridation prevalence (for years 1992, 2000, 2002, 2004, 2006, and 2008) were obtained from the Centers for Disease Control and Prevention<\/a> website, and then statistical analyses were performed using these estimates. The authors concluded that there is an association between ADHD prevalence and fluoridation prevalence and hence the fluoridated water may be an environmental risk factor. However, some of the findings are not consistent with their hypothesis of interest and also, the internal validity of this fluoride ADHD study is highly questionable. The authors acknowledged that there was no previous research linking fluoridation to ADHD. At best, this study can serve to generate a hypothesis. As it stands, this study is not a strong argument for concern.<\/p>\n\n\n\n
