Abstract:
Objective:To investigate the current prevalence and control status of coal-burning-borne endemic fluorosis in key areas of the disease in Zhenxiong County of Yunnan Province, thereby providing scientific basis for formulating subsequent prevention strategies and measures.Methods:From October to November 2023, a simple random sampling method was used to conduct a survey in three key townships (towns) in Zhenxiong County, Chishuiyuan Town, Yanyuan Town, and Linkou Yi and Miao Ethnic Township. Three administrative villages were selected from each township (town) as survey sites, and dental fluorosis examination on children aged 8 - 12 years who were born and lived in the local area was conducted. Thirty households were selected from each survey site, the use of household stoves and the formation of related healthy living behaviors were investigated. At the same time, a survey was conducted among primary school students and housewives to investigate their knowledge of coal-burning-borne endemic fluorosis prevention and control. The control and elimination of endemic areas were evaluated according to the "Assessment Protocol for Control and Elimination of Key Endemic Diseases (2019 Edition)".Results:A total of 1 172 children were examined, and the detection rate of dental fluorosis was 7.76% (91/1 172), with a dental fluorosis index of 0.11. A total of 295 households were investigated, and the qualified improved stoves rate and the correct use rate of qualified improved stoves were 95.59% (282/295) and 100% (282/282), respectively. The correct drying rate of edible corn and chili peppers was 79.66% (235/295). The awareness rates of coal-burning-borne endemic fluorosis prevention and control knowledge among housewives and primary school students were 46.69% (409/876) and 82.49% (440.5/534), respectively. Among the 9 villages investigated, two villages had met the criteria for eliminating endemic disease areas, two villages had met the criteria for controlling endemic disease areas, and the remaining 5 villages were uncontrolled.Conclusions:After implementing the comprehensive prevention and control measures mainly based on changing stoves, coal-burning-borne endemic fluorosis condition in Zhenxiong County has been effectively controlled, but there is still a significant gap between the elimination goals of some endemic fluorosis areas. Therefore, it is necessary to continue to strengthen prevention and control measures and promote health education.
