摘要
目的掌握全国饮水型地方性氟中毒（简称地氟病）防治措施落实进度、防治效果及病情变化动态。为制定饮水型地氟病防治策略提供科学依据。方法按全国地氟病监测方案规定的方法和要求进行。结果①饮水型地氟病病区防治措施落实进度仍然呈现增长，改水率增长2．52％；（爹改水降氟工程合格率明显下降，2003年为69．33％，2004年为67．09％，下降了2．24个百分点；⑧居民饮水氟（均值）已有61．29％达到国家标准。〉2．0mg／L的只有4个村电，另一部分虽然超过国家标准，但并不很高，属轻病区水平；④监测点儿童氟斑牙检出率仍普遍超过30％控制线。但主要集中在30％-70％，而超过70％检出率的仅占19-35％。结论①饮水型地氟病病区的防治措施落实进度虽然仍呈现增长趋势，但是地区差别很大，高者甚高，低者甚低；②改水降氟工程呈现增长，改水降氟工程合格率表现为下降。不具同步性，与降氟工程的年久失修、报废或改水工程未达到降氟要求有关；③饮水型病区病情仍然存在，且有些病区病情相当严重。
Objectives To investigate the outcome and effect of countermeasures for endemic fluorosis of drinking water type and to find out the trends of prevalence of this disease in China to provide scientific basis for the set up of control strategies. Method The surveillance was carried out according to the methods and requirement of The National Survey Scheme of Endemic Fluorosis. Results ①The implement of control measures was improved in drinking water type endemic areas, the improved drinking water was increased by 2.52%. ②The qualified waterimproving and defluoride projects was decreased obviously, being 67.09% and 69.33% in 2004 and 2003 respectively, decreased by 2.24 percent. ③61.29% of drinking water met the national standard of averaged fluoride levels. Fluoride content was higher than 2.0 mg/L in 4 villages and exceeded national standard a little bit in the rest of the villages which were rated as mild endemic area. ④Detectable rates of dental fluorosis in children in survey spots were generally 30% above the control line, mainly in the range of 30% - 70%. Areas with a detectable rate higher than 70% only accounted for 19.35%. Conclusions ①The implement of countermeasures in drinking water type areas keeps increasing, but it varies dramatically among areas. ②The decreased qualified water-improving and defluoride projects are contradictory to the increased amount of projects, which is probably related to the disrepair and discard of the projects or failure to reach the requirement of decreasing fluoride. ③The drinking water type fluorosis still exists and quite serious in some areas.
