Abstract

Objective To find out the dynamics of drinking water borne endemic fluorosis in Tibet's, to evaluate the effect of control measures, and to provide a scientific basis for the timely adjustment of control strategies. Methods During september to october 2009, according to the "2008 Central Government Special Funds to Subsidize Local Public Health in Drinking Water Borne Fluorosis in Tibet", Xigaze Xietongmen and Nyingchi Zayu were selected as project counties, three project villages were selected with simple random sampling method in each county, the functioning of water improvement projects, drinking water fluoride content, children's dental fluorosis and adult skeletal fluorosis were investigated. Water fluoride was detected by the "standard examination methods for drinking water the non-metallic targets"(GB/T 5750.6-2006) determination of fluoride; urinary fluoride was tested by ion selective electrode (WS/T 89-1996); dental fluorosis was diagnosed using Deans method; adult skeletal fluorosis was diagnosed by "endemic skeletal fluorosis clinical diagnostic criteria" (WS 192-2008). Results Mean water fluoride was 0.18 - 0.34 mg/L in drinking water changed areas, and 0.70 - 2.13 mg/L in not changed areas; prevalence of dental fluorosis of children 8 - 10 was 50.78% (65/128), dental fluorosis index was 1.04,mean urinary fluoride was 1.64 mg/L in drinking water changed areas; prevalence of dental fluorosis of children 8 -10 years old was 80.65%(25/31 ) in not changed areas, dental fluorosis index was 1.50, mean urinary fluoride of children was 2.08; adult clinical skeletal fluorosis was 38.7%(104/269) in drinking water changed areas, the mean urinary fluoride was 1.61 mg/L, prevalence of skeletal fluorosis was 15.4% (18/117) in not changed areas, mean urinary fluoride was 3.54 mg/L. Conclusions The method of change the water to reduce fluoride decreases dental fluorosis to control levels, and severity is also reduced, urinary fluoride is decreased. However, the prevalence of skeletal fluorosis is higher than that of drinking water not changed areas. Key words: Fluoride poisoning; Change the water; Data collection

2009年西藏自治区饮用水氟中毒监测分析

目的了解西藏饮水地方性氟中毒动态，评价各项防治措施的效果，为及时调整防治策略提供科学依据。方法2009年9 - 10月，根据《2008年西藏饮水性氟中毒地方公共卫生专项资金》，选择日喀则谢通门和林芝扎玉为项目县，采用简单随机抽样法，在每个县选择3个项目村，对改水工程的运行情况、饮用水氟化物含量、儿童氟牙症和成人氟骨症进行调查。水中氟化物的检测采用《饮用水非金属指标检验方法》(GB/T 5750.6-2006)中氟化物的测定;用离子选择电极检测尿氟化物(WS/T 89-1996);采用Deans法诊断氟牙症;成人氟骨症的诊断依据“地方性氟骨症临床诊断标准”(WS 192-2008)。结果饮用水改变区平均水氟含量为0.18 ~ 0.34 mg/L，未改变区平均水氟含量为0.70 ~ 2.13 mg/L;8 ~ 10岁儿童氟斑牙患病率为50.78%(65/128)，氟斑牙指数为1.04，饮水改变区尿氟平均为1.64 mg/L;未变地区8 ~ 10岁儿童氟斑牙患病率为80.65%(25/31)，氟斑牙指数为1.50，儿童尿氟平均为2.08;饮用水改变地区成人临床氟骨症患病率为38.7%(104/269)，尿氟平均为1.61 mg/L，未改变地区氟骨症患病率为15.4%(18/117)，尿氟平均为3.54 mg/L。结论换水降氟法可使氟牙症达到控制水平，且严重程度降低，尿氟含量降低。然而，氟骨症的患病率高于未改变饮用水的地区。关键词:氟化物中毒;换水;数据收集
