Epidemiological Investigation of Endemic Fluorosis in Rural Areas in Three Districts of Fuyang City

Objective To understand the fluoride contents of drinking water and the prevalence of fluorosis in some villages of Fuyang city, provide the scientific guideline for water supply improvement projects. Methods Investigation was conducted according to the technical project of high fluorin fountain screening about drinking water, regional fluorosis survey, and quality supervise of reducing fluorin and purifying water project and water quality testing, which included regional illness control and prevention program sponsored by Anhui province public health special funds supplemented by central government, all work were done in the downtown of Fuyang City that acting as a program county. Results 3660 water samples were collected in 732 administrative villages governed by the downtown. The testing results demonstrated that the concentration of fhiorin in 346 water samples overstepped the maximum limit of the concentration of fluorin in water （ the concentration of fluorin in water ≥ 1.0 mg/L） , which accounted for 9.45% of the total water samples. There were 126 administrative villages whose averaged concentration of fluorin in water overstepped the max - limit of the concentration of fluorin in water, which accounted for 17.21% of the total administrative villages. 36569 children whose ages were 8 - 12 years were surveyed in the downtown, and results showed that 5237 children had dental fluorosis, accounted for 3.21% of the total children surveyed. There were 3820 children whose dental fluorosis were very slight, accounted for 10.45% of the total children who had dental fluorosis, and 1175 whose dental fluorosis were slight, accounted for 3.21%, and 242 whose dental fluorosis were moderate, accounted for 0. 66%, and 21 whose dental fluorosis were severe, accounted for 0. 06%. 533 adults whose ages were older than 16 years were surveyed in the high fluorin district. Of them, 6 bone fluorosis cases were found, with incidence 1.13%. Conclusions Rural areas in three districts of Fuyang city were low prevalence zone o
