目的了解孟津县燃煤污染型氟中毒现状,为防治工作提供决策依据。方法按《全国疾病预防控制机构工作规范(2001版)》中氟中毒的监测方法调查。了解住房结构和用炉习惯,主要食物以及粮食干燥、贮藏方法,测量水氟、尿氟、氟斑牙和氟骨症等指标。结果抽样调查16个村燃煤基本没变,生活饮用水、住房条件、经济收入明显改善,病情显著下降;尿氟和水氟显著相关;氟斑牙流行指数、氟斑牙检出率与尿氟的相关性不强。氟斑牙检出率差和原检出率呈显著直线正相关。结论随着经济的发展,氟斑牙检出率明显下降,对于原病情较重的村可根据回归方程y=1.088x-49.92%(y为检出率下降差,x为原检出率)预测,可减少调查工作量。
Objective To understand the status quo of coal-contaminated fluorosis in Mengjin County and provide the basis for prevention and control. Methods According to “National Disease Prevention and Control Agency Code of Practice (2001 Edition)” fluorosis detection methods survey. To understand the housing structure and the habit of using the stove, the main food and food drying, storage methods, measuring fluoride, urinary fluoride, dental fluorosis and skeletal fluorosis and other indicators. Results The 16 coal-fired villages in the villages were basically unchanged. The drinking water, housing conditions and economic income of the villages were significantly improved, and their condition significantly decreased. Urinary fluoride was significantly associated with fluoride. The prevalence of dental fluorosis, The relevance of fluorine is not strong. The difference between the detection rate of dental fluorosis and the original detection rate showed a significant linear positive correlation. Conclusion With the economic development, the detection rate of dental fluorosis decreased significantly. For the former serious village, according to the regression equation y = 1.088x-49.92% (y is the difference between the detection rate and the original detection rate) Forecasts can reduce survey workload.
