2008年福建省饮水型地方性氟中毒病区监测结果分析

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。

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

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.
