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 understand the status of endemic fluorosis and endemic fluorosis in Fujian Province. Methods According to the principle of stratified cluster sampling, 6 villages with mild disease area and 4 villages with medium disease area were selected as the investigation points. Fluoride and dental fluorosis of children aged 8-12 years were determined at each investigation point. 16-year-old and above clinical fluorosis and X-ray examination. Results The fluoride mean of drinking water was lower than 1.0 mg / L in 10 wards, and the dental fluorosis in 9 villages was less than 30%. The urinary fluoride geometric mean of children and children in 10 wards did not exceed 1.4 mg / L. The detection rate of clinical skeletal fluorosis was 4.42%, and the detection rate of skeletal fluorosis was 19.82%. Conclusion Drinking water fluoride poisoning effect of water diversion measures is significant, clinical and X-ray diagnostic criteria of skeletal coherence remains to be further explored.
