2008年福建省饮水型地方性氟中毒病区监测结果分析

Analysis on Drinking Water Type Endemic Fluorosis Area of FuJian in 2008

目的了解福建省地方性氟中毒轻、中病区现状。方法按照分层整群抽样的原则,抽取轻病区村6个,中病区村4个作为调查点,每个调查点测定饮用水氟、8～12岁儿童氟斑牙和尿氟、对16岁及以上成人进行临床氟骨症检查和X线检查。结果10个病区村饮水氟均值均低于1.0 mg/L,9个村儿童氟斑牙低于30%,10个病区村儿童尿氟几何均数均未超过1.4 mg/L。临床氟骨症检出率4.42%,X线氟骨症检出率19.82%。结论饮水型氟中毒实施改水措施效果显著,临床与X线氟骨症诊断标准的衔接还有待于进一步探讨。

Objective To investigate the prevailing status of endemic fluorosis in mild and moderate endemic area.Methods Based on stratified cluster sampling,we selected survey spot including 6 mild endemic area and 4 moderate endemic area,determined fluoride levels of drinking water,dental fluorosis and urinary fluorine in child aged 8 to 12 and examined the skeletal fluorosis and X-ray in adult aged more than 16.Results Averaged fluoride levels of drinking water were lower than 1.0mg/L in 10 survey spots.The prevalence of children dental fluorosis was lower than 30% in 9 survey spots,the geometry mean of children urinary fluorine was lower than 1.4mg/L in 10 survey spots.The prevalence rate of clinical skeletal fluoride is 4.42%,the prevalence rate of X-ray skeletal fluoride is 19.82%.Conclusions The result of water-improving measure in endemic fluorosis of drinking water type is remarkable,the relationship between clinical and X-ray diagnose criterion of skeletal fluoride should be further studied.
