Objective To understand the extent of endemic fluorosis in drinking tea in Sunan Yugur Autonomous County (Sunan County) of Gansu Province and to provide a scientific basis for the formulation of plans and measures for prevention and control of drinking-type fluorosis. Methods Epidemiological survey methods were used to understand the prevalence of adults and children and to investigate the content of fluoride in brick tea and drinking water. Results Fluorosis was not detected in adults. The detection rate of dental fluorosis in children was 14.81%. The content of fluorine in brick tea was 609.3-854.4 mg / kg, with an average of 706.5 mg / kg. Conclusion Both farmers and herdsmen in Sunan County have the habit of drinking tea. The content of fluorine in brick tea is higher than the standard of ≤300 mg / kg in the country and belongs to the endemic fluorosis area with drinking tea.
