目的掌握阿勒泰地区饮用水氟含量及儿童氟斑牙的流行状况。方法参照《全国地方性氟中毒监测方案》的具体要求进行调查。结果在抽检的94份水样中,水氟中位数为0.51 mg/L,水氟含量超过国家标准的有14份,占14.9%;在调查的1 480名6～12岁儿童中,查出氟斑牙患者411人(27.8%)。儿童氟斑牙患病率以青河县和富蕴县最高,分别为36.9%和36.2%;水氟含量(中位数)与儿童氟斑牙患病率未见明显的相关性。结论阿勒泰地区存在局域性高氟区,儿童氟斑牙的成因与饮水和饮茶双重蓄积作用有关。
Objective To understand the fluoride content of drinking water and the prevalence of dental fluorosis in Aletai region. Methods According to the “National Plan of Surveillance of endemic fluorosis” specific requirements for investigation. Results Among the 94 water samples sampled, the median of water fluoride was 0.51 mg / L, and the content of fluoride in water exceeded 14% of the national standard, accounting for 14.9%. Of the 1 480 children aged 6 to 12 411 dental fluorosis patients (27.8%). The prevalence of dental fluorosis in children was highest in Fuhe County and Qinghe County, accounting for 36.9% and 36.2% respectively. No significant correlation was found between the fluoride content (median) and the prevalence of dental fluorosis in children. Conclusion There are localized high fluoride areas in Aletai area. The causes of dental fluorosis in children are related to the dual accumulation of drinking water and drinking tea.
