目的为燃煤型地方性氟中毒预防与控制评价指标科学定权以及应用适宜综合评价方法提供科学依据。方法对贵州省2004～2006年度项目基线资料主要指标数据进行统计学相关和回归分析,排列主要影响因子、次要因子及无关因子。结果相关分析中,玉米煤火烘烤率、辣椒煤火烘烤率、学生知晓率和户主知晓率等与儿童氟斑牙检出率显著相关,玉米食前淘洗率和辣椒食前淘洗率处在边缘,学生知晓率与户主知晓率呈显著相关;以儿童氟斑牙检出率为自变量,作逐步回归分析,仅台灶敞烧率和辣椒煤火烘炕率进入方程。结论台灶敞烧率和辣椒煤火烘炕率两指标为主要影响指标,为主因子;学生知晓率越高,住户知晓率越高,敞炉灶烧煤率越低,煤火烘炕辣椒率越低。
Objective To provide a scientific basis for scientific determination of coal-based endemic fluorosis prevention and control evaluation index science and the application of appropriate comprehensive evaluation methods. Methods The main index data of baseline data of project in Guizhou Province from 2004 to 2006 were statistically analyzed and the regression analysis was conducted. The main influential factors, secondary factors and irrelevant factors were arranged. Results Correlation analysis showed that there was a significant correlation between the detection rate of dental fluorosis in children and the pre-panning rate of peppers At the edge, there was a significant correlation between the awareness rate of students and the head of household awareness rate. With the detection rate of children’s dental fluorosis as an independent variable, a stepwise regression analysis was conducted. Conclusion The firing rate of the stove and the rate of burning hot konjac in chilli peppers are the main factors. The higher the students’ awareness rate is, the higher the household awareness rate is. The lower the open coal stove firing rate is, the lower the coal firing rate is Lower.
