摘要
目的了解山东省鲁西南地区的地方性氟中毒病情现状,为制定防治策略提供科学依据。方法采用流行病学调查方法,选择11个县进行调查,水、尿氟含量测定采用氟离子选择电极法,8～12岁儿童氟斑牙诊断采用Dean’s法,临床和X线摄片检查氟骨症。结果在11个县中,调查20个改水村,水氟均值≤1.00 mg/L的村14个,占70.00%(14/20);>1.00 mg/L的村6个,占30.00%(6/20);水氟最大值为3.73 mg/L。调查13个未改水村,水氟均值≤1.00 mg/L的村3个,占23.08%(3/13);>1.00 mg/L的村10个,占76.92%(10/13),水氟最大值为3.38 mg/L。8～12岁儿童氟斑牙总患病率为39.17%(597/1 524),氟斑牙指数为0.75,缺损率为3.94%(60/1 524)。儿童尿氟均值在1.40 mg/L以上的人数占42.13%(642/947),最高值为18.53 mg/L。16岁以上成人的氟骨症临床和χ线检出率分别为5.88%(1235/20 980)、8.00%(2/25)。成人尿氟均值在1.60 mg/L以上的人数占65.34%(1 130/2 023),最高值为13.97 mg/L。结论山东省鲁西南地区的地方性氟中毒病情尚未得到有效的控制,防治形势依然比较严峻,需进一步加大防治力度。
Objective To investigate the status of an illness of endemic fluorosis in the southwestern region of Shandong province at present,and to provide the scientific evidence for making strategies for the prevention and control.Methods To adopt the method of Epidemiological investigation,11 counties were chosen to carry out the investigation of endemic fluorosis.The content of fluoride in drinking water and urine was determined by F-ion selective electrode,dental fluorosis of children aged 8 to 12 years old was diagnosed by Dean＇s method and diagnosed skeletal fluorosis by clinic and X-rays.Results The investigation was used in 20 water-improving villages in 11 counties,among which 14 villages had water fluoride content ≤ 1.00 mg/L and accounted for 70.00%（14/20）,6 villages had water fluoride content 1.00 mg/L and accounted for 30.00%（6/20）,the highest water fluoride content was 3.73 mg/L.The investigation was used in 13 non-water-improving villages in 11 counties,among which 3 villages had water fluoride content ≤ 1.00 mg/L and accounted for 23.08%（3/13）,10 villages had water fluoride content 1.00 mg/L and accounted for 76.92%（10/13）,the highest water fluoride content was 3.38 mg/L.The total rate of dental fluorosis of children aged 8 to 12 years old was 39.17%（597/1 524）,the index of dental fluorosis was 0.75 and the rate of dental damage was 3.94%（60/1 524）.The urinary fluoride values above 1.40 mg/L were found in 42.13%（642/947）of children aged 8 to 12 years old,with the highest urinary fluoride concentrations was 18.53 mg/L.The rate of skeletal fluorosis by clinic and X-rays in adults older than 16 years old were 5.88%（1 235/20 980）and 8.00%（2/25）,respectively.The urinary fluoride values above 1.60 mg/L were found in 65.34%（1 130/2 023）of adults older than 16 years old,with the highest urinary fluoride concentrations was 13.97 mg/L.Conclusions The status of an illness of endemic fluorosis is not effectively controlled and the preventive situation for endemic fluorosis control is still very severe in the southwestern region of Shandong province.So preventive working for endemic fluorosis control should be strengthened.
