湖南省燃煤污染型氟中毒防制点基线调查

A Baseline Survey in Control of Burning Coal Fluorosis in the Pilot Area of Hunan Province

目的分析耒阳市燃煤污染型氟中毒病区开展健康教育干预措施的可行性与传播策略。方法对试点村进行抽样调查。结果8～12岁学生氟斑牙率71.92%;成人X线氟骨症检出率35.6%;8～12岁学生尿氟含量>1mg/L为76.69%;各住户均敞灶烧煤,80%居民具有小学以上文化程度,年人均收入1000～2500元;有线电视入户率大于80%;目标人群地氟病防治知识知晓率1.88%。结论试点村燃煤污染型氟中毒的发生主要与当地人群不文明生活习惯有关。当地人群对地氟病及防治知识缺乏。耒阳市具备健康教育干预的基本条件,具有可行性。

Objective To evaluate the feasibility of health education program and propagation tactics of burning coal fluorosis areas in Leiyang City. Method Sampling investigation was conducted in an experimental village. Results The incidence of dental fluorosis of 8- 12 years old students was 71.92%. The positive rate of adult skeletal fluorosis was 35.6%. There was 76.69 % students aged 8 ～ 12 years whose urinary fluorine level was higher than 1mg/L. The residents burned coal with the open stoves, 80 % residents had a diploma of elementary school, and the average yearly income was in the range of 1,000-2,500 RMB. The coverage of cable TV was over 80%. Only 1.88% among the target population had some knowledge concerning the control of endemic coal combustion fluorosis. Conclusion The prevalence of endemic fluorosis is related to the poor hygienic condition of the residents and lacking of knowledge of endemic fluorosis. The pilot areas have already had the basic conditions of carrying on the project; and the feasibility is obvious.
