Abstract:
Objective:To investigate the current situation and changing trends of coal-burning-borne endemic fluorosis (coal-burning-borne fluorosis) areas in Henan Province, and evaluate the effectiveness of prevention and control measures.Methods:From 2019 to 2021, monitoring was carried out in all villages affected by coal-burning-borne fluorosis in Henan Province. A simple random sampling method was used to select 30 households in each affected village each year to investigate the use of stoves and the formation of related healthy living behaviors. According to the criteria of "Diagnosis of Dental Fluorosis" (WS/T 208-2011), all children aged 8 to 12 in the affected villages were examined for dental fluorosis. The evaluation for control and elimination of the disease areas was carried out in accordance with the "Evaluation Approach for Control and Elimination of Priority Endemic Diseases (2019 Edition)".Results:From 2019 to 2021, a total of 7 472 households were monitored, the rate of qualified improved stoves were all ≥99.80%, the correct use rate of qualified improved stoves and correct drying of corn and pepper were reached 100%. From 2019 to 2021, the prevalence of dental fluorosis in children was 5.38% (237/4 405), 5.18% (232/4 477), and 3.68% (145/3 937), respectively, showing a declining trend (χ 2trend = 12.73, P < 0.001). The prevalence of dental fluorosis among children in affected villages was less than 15%. From 2019 to 2021, all affected villages in coal-burning-borne fluorosis in Henan Province had met the elimination criteria. Conclusion:Coal-burning-borne fluorosis areas in Henan Province have been continuously eliminated, with significant prevention and control effects, and the disease has been effectively controlled.
