摘    要:目的了解1991-2005年广东省丰顺县饮水型氟中毒病区实施改水降氟防治措施后的病情动态。方法在饮水型氟中毒病区大寨村、湖陂村和安全村,进行连续15年的监测,采用氟离子电极法检测饮水氟和儿童尿氟,Dean法检查儿童氟斑牙,X线检查成人氟骨症。结果大寨村、湖陂村和安全村儿童氟斑牙检出率总体呈逐年下降趋势,但中间有波动,氟斑牙指数分别从1991年的1.5、3.0、1.3下降到2005年的0.8、0.9、0.2,流行强度达到轻微或阴性流行标准。2002年以来3个村儿童尿氟〈1.50mg/L。成人氟中毒患病率和氟骨症X线检查阳性率逐年下降。结论饮水型氟中毒病区通过改水降氟后,人群总摄氟量减少.氟中毒有一定程度减轻,说明改换水源是预防饮水型氟中毒最有效的方法,但要规范管理改水降氟设施的使用。

Abstract:Objective To investigate the fluorosis situation after measures having been taken to improve water and decrease fluorine in water-related endemic fluorosis area in Guangdong Province. Methods Dazhai Village, Hupo Village and Anquan Village in Fengshun County, an intense water-related endemic fluorosis area, were randomly chosen as surveillance spot and had been observed for 15 years. Fluoride content in drinking water and fluoride in child urine were assessed. And dental fluorosis of children was examined with Dean index, skeletal fluorosis in adults was examined with X-ray. Results The prevalence rate of dental fluorosis of students fluctuated, but decreased gradually. The dental fluorosis index in Dazhai Village, Hupo Village and Anquan Village decreased from 1.5, 3.0, 1.3 to 0.8, 0.9, 0.2, respectively, meeting the criteria of mild and non-endemic areas. Urine fluoride concentration of children in the three villages all had been within the limit of 1.50 mg/L since 2002. The prevalence rate of adult fluorosis and positive detection rate of skeletal fluorosis examined by X-ray decreased gradually. Conclusions After measures having been taken to improve water and decrease fluorine in water-related endemic fluorosis area, the total fluorine intake by population and the level of fluorosis decreased, indicating that the most efficient method for preventing drinking water fluorosis was altering water source. However, the management of improving water facilities should been strengthened.
