摘要
目的分析黑龙江省饮水型地方性氟中毒病情现状,为评价综合防治措施及效果提供依据。方法根据国家相关方案,按水氟含量的轻、中、重,选择7个县,对每个县采用单纯随机抽样方法抽取3个病区村（屯）,进行生活饮用水氟含量及氟斑牙检测。结果调查已改水村10个,水氟含量〈1.2mg/L的有7个村,水氟含量〉1.2mg/L且≤2.0mg/L的有3个村;共检查8~12岁儿童287人,检出氟斑牙患者9例,氟斑牙检出率为3.1%。未改水村11个,水氟含量〉1.2mg/L且≤2.0mg/L的村有9个,水氟含量〉2.0mg/L且≤4.0mg/L的村有1个,水氟含量〉4.0mg/L的村有1个;检查8~12岁儿童219人,检出氟斑牙患者42例,检出率为19%。儿童氟斑牙的检出率差异有统计学意义（χ^2=28.40,P〈0.01）。结论改水工程对病区村（屯）氟中毒疫情控制有明显的效果。
Objective To analyze endemic fluorosis of drinking water type in Heilongjiang province, and provide basis for comprehensive prevention and control measures and evaluation. Methods According to related national programs, 21village（Tun） were randomly selected from seven counties based on water fluoride content,and the fluoride content in drinking-water were detected and dental fluorosis was checked out. Results Ten villages carried out the water improvement project,seven of which has water fluoride content of under 1.2mg/L and three of which hae water fluoride content between 1.2mg/L to 2.0mg/L. Nine cases of dental fluorosis were found in 287 children aged 8-12 years old with a prevalence rate of 3.1%.Eleven villages haven＇t the water improvement project, and 9 of them has water fluoride content between 1.2mg/L to 2.0mg/L,one village with the content over 2.0mg/L less 4.0mg/L and one village with water fluoride content of over 4.0mg/L. 42 cases of fluorosis were found out among 219 children aged 8 to 12 years old with dental fluorosis prevalence rate of 19%. There are statistically significant different in dental fluorosis（ χ^2=28.40,P〈0.01）.Conclusion The water improvement project has obvious effect in controling the endemic fluorosis epidemic.
