目的调查闽侯县后福自然村是否存在地氟病流行及新病区。方法按照《地方性氟中毒病区划分标准》调查人群中8～12岁的氟斑牙、尿氟及居民饮用水中水氟含量。结果水源水的水氟浓度为2.66mg/L,末梢水的水氟浓度为2.67mg/L,8～12岁学生尿氟含量几何均数为1.48mg/L,氟斑牙患病率41.0%。结论调查人群的氟斑牙流行强度为轻微,后福自然村为新发现的饮水型地方性氟中毒轻病区。
Objective To investigate the existence of endemic fluorosis and new ward in Fuhou Nature Village in Minhou County. Methods According to “Division of endemic fluorosis ward criteria” to investigate the population of 8 to 12-year-old dental fluorosis, urinary fluoride and drinking water fluoride content. Results The water fluoride concentration in source water was 2.66mg / L, the water fluoride concentration in peripheral water was 2.67mg / L, the geometric mean urinary fluoride content in students aged 8 ~ 12 was 1.48mg / L, the prevalence of dental fluorosis was 41.0% . Conclusion The prevalence of dental fluorosis in the surveyed population is slight, and Houfu Natural Village is the newly discovered drinking water endemic fluorosis area.
