FAN Bulletin 1026: Another meta-analysis of Chinese IQ studies published
December 27, 2008
Another meta-analysis of Chinese studies showing a possible relationship between fluoride exposure and lowered IQ has just been published. This study by Liu and Cian of the Department of Health Statistics, China Medical University, in Shenyang, China was published in Chinese (see the English abstract below). The authors reviewed 13 individual studies and found that their statistical analysis suggested "a negative correlation between high fluorosis exposure and children's intelligence development" and concluded that "Exposure to high levels of fluoride may adversely influence children's intelligence development." FAN will be using some of the money we are raising right now to have this translated, along with the other 5 Chinese IQ studies which are still only available in Chinese.

This study by Liu ad Cian comes on the heels of the study by Tang et al. (2008) published in August and an analysis by Connett, M and Limeback, H, presented at the IADR conference in Toronto, in July. All three reviews have yielded similar conclusions.

Links to all 23 individual studies (from India, Iran, Mexico and China) which report an association between fluoride exposure and lowered IQ in children is at http://fluoridealert.org/iq.studies.html

One wonders how long zealous promoters of fluoridation will be able to maintain the fiction that saving at most 0.6 of one permanent tooth surface (Brunelle and Carlos, 1990) can possibly justify risking the development of our children's brains. This third review of the issue certainly provides another reason for more professionals to sign the statement calling for an end to fluoridation worldwide, as well as more ammunition for our 2009 campaign. But we still have to finance that campaign. Which brings us to FAN's fundraiser.

FAN FUNDRAISER

As of 5 pm today we had raised $22,249 from 175 donors towards our revised goal of $40,000 by midnight, Dec 31, 2008. Don't forget contributions are tax-deductible so if you are in the position to do so make sure your contribution goes to us and not Uncle Sam!

Hearing of the importance of getting as many donors as possible, as well as reaching our financial target, a very generous supporter has issued this challenge: If we can get donations of $10 or more from 20 people by midnight tomorrow night, she will donate $1000 to our total.

Don't forget for

$50 donations you can get "Fluoride Poisoning" by Bruce Spittle as a gift.
$75 donations you can get ""Fluoridation: The Secret War" by Geoffrey Smith (only 3 copies left).
$100 donations you can a copy of the 28 minute DVD - A compilation of Professionals explaining their opposition to fluoridation.

Making a secure tax-deductible donation online is very easy and quick to do. Simply click here. If you prefer, you can send a check, in US$, payable to FAN to: Paul Connett, 82 Judson Street, Canton NY 13617.

New meta-analysis from China (abstract)

Title: Effect of endemic fluorosis on children's intelligence development: a Meta analysis.
Authors: Liu M, Qian C. Department of Health Statistics, China Medical University, Shenyang 110001, China.
Journal: Zhongguo Dang Dai Er Ke Za Zhi. 2008 Dec;10(6):723-5. [Article in Chinese]

OBJECTIVE: To investigate the effect of high levels of fluoride on children's intelligence development by analyzing the literatures systematically.
METHODS: The literatures on the relationship between endemic fluorosis and children's intelligence development published between 1995 and 2007 were retrieved electronically and manually. A total of 13 relevant literatures that met the inclusion criteria were included for Meta analysis. Meta analysis was performed using the Coorporative network software RevMan 4.3.
RESULTS: The subjects of the 13 literatures included 2 508 children from the high fluoride group and 2 330 children from the control group. Meta analysis showed these literatures were inhomogenous (x2=268.05, p<0.01). Therefore a random effect model was used. The average effect scale (OR=-7.14; 95%CI: -9.90, -4.37) suggested a negative correlation between high fluorosis exposure and children's intelligence development.
CONCLUSIONS: Exposure to high levels of fluoride may adversely influence children's intelligence development.
