To study the influence on children’s growth by long-term high fluoride exposure.
Case group was selected in high fluoride areas and control group was selected in non-high fluoride areas. The difference of children’s growth levels were analyzed between 2 groups.
The IQ of case group was significantly lower than that of control group (t = 2.621, P<0.01) and it was negatively correlative with the concentration of children’s urinary fluoride in a certain extent (r = -0.119, P<0.05). Children’s heights and weights of case group were significantly lower than those of control group (t = 2.621, P<0.01 u = 3.515 P < 0.01).
Long-term fluoride exposure can affect children’s growth and development. In order to protect children’s health measures of prevention and treatment should be adopted.
OP V – 2 Prenatal fluoride exposure and neurobehavior among children 1–3 years of age in Mexico
Background/aim Recent studies report an inverse association between fluoride (F) exposure and IQ in children, but few included individual measures of exposure or assessed associations with prenatal exposure using a prospective study design. Methods This study utilised the Early Life Exposures in Mexico to Environmental Toxicants (ELEMENT) birth cohort and archived pregnancy samples
Effect of coal-burning endemic fluorosis on children's physical development and intellectual level
Objective To investigate the effect of coal-burning endemic fluorosis on children's physical development and intellectual level so as to provide data support for the protection of children's healthy growth in fluorosis areas. Methods Ninety children with coal-burning endemic fluorosis were selected for the study, which were divided into heavy fluorosis area group, middle
Prenatal Fluoride Exposure and Cognitive Outcomes in Children at 4 and 6–12 Years of Age in Mexico
Background: Some evidence suggests that fluoride may be neurotoxic to children. Few of the epidemiologic studies have been longitudinal, had individual measures of fluoride exposure, addressed the impact of prenatal exposures or involved more than 100 participants. OBJECTIVE: Our aim was to estimate the association of prenatal exposure to fluoride with
A correlation between serum vitamin, acetylcholinesterase activity and IQ in children with excessive endemic fluoride exposure in Rajasthan, India
Fluoride is widely distributed in nature and a direct source of adverse health effects in human populations. Fluoride poisoning attributed by long-term exposure to high levels of fluoride [is] called fluorosis. The present study was carried out among 9-14 years old school children of Dausa district, Rajasthan India. The subjects
Investigation and evaluation on intelligence and growth of children in endemic fluorosis and arsenism areas.
“This study investigated the effects of arsenism and fluorosis on the mental ability (MA) and growth of children living in areas endemic for arsenism, fluorosis , or both. The children were divided into high arsenic/fluoride group (group 1), high fluoride group (group 2), high arsenic group (group 3), and control

Factors which increase the risk for skeletal fluorosis
The risk for developing skeletal fluorosis, and the course the disease will take, is not solely dependent on the dose of fluoride ingested. Indeed, people exposed to similar doses of fluoride may experience markedly different effects. While the wide range in individual response to fluoride is not yet fully understood, the following are some of the factors that are believed to play a role.
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
Fluoride & IQ: The 65 Studies
As of May 2020, a total of 73 studies have investigated the relationship between fluoride and human intelligence. Of these investigations, 65 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
Dental Fluorosis & Enamel Hypoplasia in Children with Kidney Disease
Children with kidney disease are known to have high levels of fluoride in their blood and to be at risk for disfiguring tooth defects. Research suggests that high levels of fluoride in blood, which can cause the tooth defect known as dental fluorosis, can contribute to the defects that occur
Genetic Susceptibility to Fluoride
"The results suggest that genetic factors may contribute to the variation in bone response to fluoride exposure.... The genetic influence on the efficacy and adverse effects has been demonstrated for some medications but has never been demonstrated for bone response to fluoride. The demonstration of such genetic influence on bone
