Abstract

Objective

To study the influence on children’s growth by long-term high fluoride exposure.

Methods

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.

Results

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).

Conclusions

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.

    Highlights Pioneer biomonitoring study on rural children to address As and F- co-exposure. High dental Fluorosis found in relation to urinary As and F- levels in children. Oxidative stress was found associated with lowered intelligence quotient levels. No significant difference was observed in the case of genetic polymorphism. Arsenic (As),

    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

    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

    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

    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

  • 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.

    As of May 2020, a total of 75 studies have investigated the relationship between fluoride and human intelligence. Of these investigations, 67 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

  • Skeletal Fluorosis & Individual Variability

    One of the common fallacies in the research on skeletal fluorosis is the notion that there is a uniform level of fluoride that is safe for everyone in the population. These "safety thresholds" have been expressed in terms of (a) bone fluoride content, (b) daily dose, (c) water fluoride level, (d) urinary fluoride level, and (e) blood fluoride level. The central fallacy with each of these alleged safety thresholds, however, is that they ignore the wide range of individual susceptibility in how people respond to toxic substances, including fluoride.
