Abstract:
Objective:To learn about the current situation of prevention and control of coal-burning-borne endemic fluorosis (coal burning fluorosis for short) in Yunnan Province, and comprehensively evaluate the implementation effect of prevention and control measures.Methods:From August to November 2020, according to the requirements of the Monitoring Program of Yunnan Province for Coal-burning-borne Endemic Fluorosis (2019 edition), monitoring was carried out in all natural villages in the disease areas of 13 counties (cities and districts, hereinafter referred to as counties) of the province, and 30 households were selected from each natural village to monitor the use of stoves and the formation of related healthy living behaviors. At the same time, children aged 8 - 12 years in the natural villages in the disease areas were examined for the prevalence of dental fluorosis. The evaluation for control and elimination of disease areas was carried out in accordance with the Evaluation Approach for Control and Elimination of Priority Endemic Diseases (2019 edition).Results:A total of 392 244 households were investigated, and the rates of qualified improved stoves, the correct utilization of qualified improved stoves and correct drying of corn and pepper were 99.42% (389 982/392 244), 99.70% (388 796/389 982) and 99.07% (388 579/392 244), respectively. A total of 227 057 children aged 8 - 12 years were examined, 9 413 children of dental fluorosis were detected, the detection rate of dental fluorosis was 4.15%, the dental fluorosis index was 0.10, and the prevalence intensity was negative. Taking the county as a unit, except Fuyuan and Zhenxiong, which reached the control standard of the disease area, the remaining 11 counties reached the elimination standard.Conclusion:The prevention and control measures on coal burning fluorosis are implemented well in Yunnan Province and healthy lifestyle has gradually taken shape, with the overall condition of the disease reduced.
