目的 了解地氟病病情及改炉改灶防治效果 ,为制定地氟病防治策略提供科学依据。方法 按照“四川省燃煤型氟中毒监测方案 (1999- 2 0 0 3)”进行儿童氟斑牙患病率调查 ,尿氟浓度、玉米和海椒氟含量测定。结果 8～ 12岁儿童氟斑牙患病率为 6 3 0 6 % ,Dean指数为 1 39,尿氟几何均值为 1 0 8mg/L (0 11～ 4 0 13mg/L)。玉米氟含量均值为 4 13mg/kg (0 0 3～ 33 2 0mg/kg) ,海椒氟含量均值为 131 4 1mg/kg (0 71～ 10 74 80mg/kg)。结论 氟中毒病情呈下降趋势 ,但部分地区病情依然严重。提高降氟灶使用率 ,改变病区居民饮食结构及海椒干燥方式 ,加大健康教育力度等综合治理方法是防治燃煤型地方性氟中毒的重要手段
Objective To understand the condition of dexifloxacin and the effect of changing the stoves on the stoves in order to provide a scientific basis for the prevention and treatment of dendofluorosis. Methods The prevalence of dental fluorosis in children was surveyed according to “Monitoring Program for Fluorine Poisoning in Sichuan Province (1999-2003)”, urinary fluoride concentration, fluorine content in corn and sea cucumber. Results The prevalence of dental fluorosis was 63.06% in children aged 8-12 years, the Dean index was 39 and the geometric mean urinary fluoride was 108 mg / L (0 11 ~ 40 13 mg / L). The mean fluoride content in maize was 4 13 mg / kg (0 0 3 ~ 33 2 0 mg / kg), and the mean fluoride content in maize was 131 4 1 mg / kg (0 71-10 740 80 mg / kg). Conclusion The incidence of fluorosis is declining, but the condition is still serious in some areas. Improve the use of fluoride-lowering stoves, to change the diet of residents in the ward and dried sea cucumber, increase health education and other comprehensive management methods is an important means of prevention and control of endemic fluorosis in coal-fired
