Abstract
Background and aim: The aim of the study was to assess the intelligence quotient of fishermen schoolchildren of Kutch, Gujarat, India.
Materials and methods: A descriptive cross-sectional study was conducted among 8 to 10 years old schoolchildren living in Kutch District, Gujarat, India, from January to February 2013. Seguin Form Board Test was used to assess the intelligence quotient (IQ) level of children. Means of groups were compared by independent student t-test. Stepwise multiple linear regression was used to identify predictors for IQ.
Results: The mean average timing taken by fishermen schoolchildren to complete the test was 30.64 ± 4.97. Males had significantly lower mean timing scores than females (p < 0.05). Participants with severe dental fluorosis, low socio-economic status (SES), lower education level of both mother and father and those who were overweight had significantly higher mean timing scores for average category.
Conclusions: The present study suggested a low IQ among fishermen schoolchildren community of Kutch, Gujarat, India. The major factors which influenced their IQ were dental fluorosis, low SES, low education level of parents and high body mass index.

Investigation of Intelligence Levels of Children of 8 to 12 Years of Age in Coal Burning-Related Endemic Fluorosis Areas.
Objective: To investigate the relationship between age, dental fluorosis and intelligence in children aged 8-12 in coal-burning fluorosis (CBF) area, Guizhou province. Methods: A cross-sectional study was conducted to investigate the prevalence of dental fluorosis and intellectual level in 284 children (n=167 for CBF area, n=120 for control are) aged 8-

Refinement Impairments of Verbal-Performance Intelligent Quotient in Children Exposed to Fluoride Produced by Coal Burning.
To explore the relationship between total intelligence quotient (IQ), verbal intelligence quotient (VIQ), performance intelligence quotient (PIQ), and fluoride exposure in children aged 8–12 years in coal-burning fluorosis area of Dafang County, Guizhou Province, China. The Wechsler Intelligence Scale for Children Revised in China (WISC-CR) was used to test the total

Association of lifetime exposure to fluoride and cognitive functions in Chinese children: A pilot study
Highlights Elevated fluoride concentrations in drinking water may be neurotoxic. We carried out a pilot study of 51 first-grade children with stable lifetime fluoride exposures. Moderate and severe fluorosis was associated with deficits in digit span total and backward scores. The dose-dependence underlying the association needs to be characterized in

Fluoride & IQ: 68 Studies
As of February 2021, a total of 76 studies have investigated the relationship between fluoride and human intelligence. Of these investigations, 68 studies have found that elevated fluoride exposure is associated with reduced IQ in humans, while over 60 animal studies have found that fluoride exposure impairs the learning and/or

Fluoride Affects Learning & Memory in Animals
An association between elevated fluoride exposure and reduced intelligence has now been observed in 65 IQ studies. Although a link between fluoride and intelligence might initially seem surprising or random, it is actually consistent with a large body of animal research. This animal research includes the following 45 studies (out

Community Fluorosis Index (CFI)
The current Community Fluorosis Index for U.S. adolescents as a whole (from both fluoridated and non-fluoridated areas) is roughly 5 times higher than the CFI health authorities predicted for fluoridated areas when fluoridation first began. It is also higher than the CFI that the NIDR found in fluoridated areas back in the 1980s. It is readily apparent, therefore, that children are ingesting far more fluoride than was the case in the 1950s, and even as recently as the 1980s.
