Abstract：

Objective To understand the status of drinking-water-borne endemic fluorosis and the effect of preventive measure in Hebei province, so as to provide a basis to prevent and cure the disease. Methods Thirtyeight affected counties(cities, districts) with drinking-water-borne endemic fluorosis were sampled by random sampling in Hebei in 2009. All affected villages in every county were divided into mild, moderate and severe endemic fluorosis areas and a village was randomly selected from each category of the area to carry out the monitoring of endemic fluorosis. Dental fluorosis of children aged 8 - 12 were examined and 6 copies of urine samples were randomly collected in each age group in the above-mentioned villages. Clinical skeletal fluorosis was diagnosed among adults aged 16 and over and 20 copies of urine samples were tested for fluorosis in every village.Results A total of 112 affected villages were investigated, among which the drinking water quality of 66 villages were improved and 46 villages were not improved. A total of 236 copies of water samples from the 66 villages were measured and the fluoride content ranged from 0.1 to 4.3 mg/L, among which 20 copies of water samples exceeded the fluorine standard of 1.2 mg/L, accounting for 33.3%. A total of 230 copies of water samples were collected in the 46 villages and the fluoride content ranged from 0.2 to 4.6 mg/L, among which 76.1% (35/46) of the water samples exceeded the fluorine standard of 1.2 mg/L. A total of 5169 children aged 8 - 12 were examined of dental fluorosis, the dental fluorosis rate was 36.43%(1883/5169) and the dental fluorosis index was 0.81. A sum of 71 497 adults aged over 16 years were examined, and the rate of skeletal fluorosis was 4.81%(3438/71 497), moderate or severe clinical detection rate of skeletal fluorosis was 1.56%( 1114/71 497). A total of 2876 copies of children urine samples and 2021 copies of adult urine samples were tested and the geometric mean of fluoride content was 2.30,3.32 mg/L, respectively. Conclusions The prevalence of dental fluorosis of children in the areas with improved water is less than 30% and the rate of dental fluorosis and skeletal fluorosis decline gradually with time.The rate of dental fluorosis and skeletal fluorosis increases with the increase of water fluoride in the water quality not improved areas. The endemic fluorosis is still comparatively serious in Hebei. The progress of improving water quality in the areas with endemic fluorosis should be accelerated and the acceptability of improved water should be enhanced.

Abstract：

Objective To investigate the running conditions of the water improvement projects and the role of these projects in reducing fluoride in drinking-water type of fluorosis in Shaanxi province, and provide a scientific basis for prevention and control of the disease. Methods Forty-eight villages of 16 counties in Xi'an, Baoji, and Yulin cities of Shaanxi province were monitored in 2009. Five water samples were collected randomly in water unimproved monitoring villages by the position of east, west, south, north, and center parts. In water improved monitoring villages, 3 tap water and one source water samples were collected. Water fluoride was tested using fluoride ion selective electrode method according to the "Standard Testing Methods for Drinking Water" (GB/T 5750-2006). All school children aged 8 to 12 in monitored villages were examined their dental fluorosis using Dean criteria. All people over 16 years old were examined clinical skeletal fluorosis, and 30% of the project counties were randomly selected, then randomly selected one village among these counties, clinically diagnosed patients with skeletal fluorosis were examined again by X-ray using "Diagnostic Criteria of Endemic Skeletal Fluorosis"(WS 192-2007). Urine samples of 30 children aged 8 to 12 and of 20 adults over the age of 16 were randomly collected, urinary fluoride was tested according to "the Determination of Urinary Fluoride by Ion Selective Electrode Method" (WS/T 89-19%). Results Of the 22 water improvement projects that in normal operation, fluoride level of 8 source waters exceeded the standard, accounting for 36.36%(8/22), and projects scrapped 5. Two hundred and two water samples were tested. In water improved historical diseased areas, the median of water fluoride of source water and tap water were 0.72,0.62 mg/L, respectively, and the average rate of water fluoride exceeded the standard ere 36.36%(8/22) and 31.94%(23/72), respectively. In water unimproved historical diseased areas, the median of water fluoride was 1.00 mg/L, and the average rate of water fluoride exceeded the standard was 39.81%(43/108). Detection rate of dental fluorosis among children aged 8 to 12 was 16.06% (367/2285), dental fluorosis index was 0.30, and the prevalence was negative. Detection rate of clinical skeletal fluorosis among adults over 16 years old was 5.09%(1542/30 272), a totally of 198 people had X-ray film taken, positive 68, the positive detection rate was 34.34%(68/198). One thousand and fifty-one copies of children's urine samples were tested, geometric mean of urinary fluoride was 0.95 mg/L; nine hundred and fourteen copies of adults urine samples were tested, geometric mean of urinary fluoride was 1.16 mg/L Conclusions Drinking-water type of fluorosis affects a large area in Shaanxi province, the disease is still serious, and the task of prevention remains very arduous. Further intensify the water improvement project in diseased areas, and strengthen disease monitoring, health education and water improvement project management is the key to prevention and control of endemic fluorosis.

目的 了解山西省临猗县饮水型地方性氟中毒的患病情况,探讨氟中毒与尿氟之间的关系,为当地饮水型地方性氟中毒的防治提供依据.方法 2006年在临猗县饮水型地方性氟中毒重、中病区和非病区各选取1个村作为调查点,采用Dean法和离子选择电极法对当地居民进行氟斑牙和尿氟检查,对病区30岁及以上成年人进行前臂正位X线(包括肘与腕)拍片,进行氟骨症患病情况调查.结果 3个地区人群氟斑牙检出率明显不同(X~2=410.945,P<0.01),其中,中病区、重病区氟斑牙检出率分别为92.34%(253/274)、90.09%(291/323),明显高于非病区[23.27%(64/275),X~2值分别为274.927、268.287,P均<0.01].重病区氟骨症检出率[59.75%(141/236)]明显高于中病区[24.76%(52/210),X~2=183.578,P<0.01].3个地区人群尿氟水平差异有统计学意义(H=411.197,P<0.01),其中重病区为(4.69±0.17)mg/L、中病区为(4.86±0.13)ms/L、非病区为(1.75±0.04)mg/L;而氟骨症患病程度与人群尿氟之间呈直线相关关系(r=0.508,P<0.01).结论 山西省临猗县饮水型地方性氟中毒病区氟斑牙、氟骨症患病情况严重,氟骨症患病程度与尿氟水平相关.     

温泉型氟病区开展健康教育后防治效果分析

目的通过了解氟病区实施健康教育后，氟中毒患病情况，变化规律及效果，以便探索防制策略。方法调查健康教育方案实施前后氟巾毒患病情况，分别进行比较。调查内容包括患氟斑牙及氟骨症的人数：水、尿、土壤、农作物、空气巾含氟量。结果实施健康教育前儿童氟斑牙检出率95．7％（453／473），战人氟骨症检出率67．0％（110／164），成人及8～12岁学生尿氟均值分别为3．4、2．7mg／L，温泉水氟9．2mg／L，河流、池塘水氟0．6mg／C，土壤氟5．1mg／kg，室内空气禽氟量0．01mg／m^3。实施健康教育后，氟斑牙检出率6．9％（16／228），氟骨症检出率19．0％（19／100），成人及8～12岁学尿氟均值分别为1．1、1．0mg／L，河流、池塘水氟0．5mg／L，土壤氟5．2mg／kg，室内空气含氟量0．0lmg／m^3。结论实施健康教育后．温泉型氟病区由氟中毒中等病区达到了基本消灭区．开展健康教育是防治地氟病的重要措施。
