目的了解若尔盖县饮茶型地方性氟中毒的病情危害程度,为制定饮茶型氟中毒防治规划和措施提供科学依据。方法按照《四川省饮茶型地方性氟中毒流行现状调查方案》。结果成人氟骨症、氟斑牙检出率高,分别是79.3%和69.1%,尿氟几何均数达1.60mg/L,超过全国正常值。儿童氟斑牙检出率38.5%,尿氟均数为0.67mg/L。茶水及砖茶氟含量都高分别是2.45mg/L、846.31mg/kg。结论若尔盖县属于典型的饮茶型地方性氟中毒,氟骨症检出率随年龄增加而增高,呈慢性、累积的氟中毒过程。氟骨症检出率与年龄呈明显的正比关系。
Objective To understand the severity of drinking endemic fluorosis in Zoige County and provide a scientific basis for the planning and measures to prevent drinking-type fluorosis. Methods According to “Sichuan Province drinking endemic fluoride endemic fluorosis survey program.” Results The incidence of skeletal fluorosis and fluorosis in adults was high, accounting for 79.3% and 69.1%, respectively, and urinary fluoride geometric mean reaching 1.60mg / L, which exceeded the national normal value. Children’s dental fluorosis detection rate of 38.5%, urinary fluoride average 0.67mg / L. Tea and brick tea fluoride content is high 2.45mg / L, 846.31mg / kg. Conclusion Ruoergai County belongs to the typical drinking tea endemic fluorosis, skeletal fluorosis detection rate increased with age, showing a chronic, cumulative fluorosis. The detection rate of skeletal fluorosis and age showed a significant positive correlation.
