摘　　要：目的了解天津市儿童饮水型氟中毒流行现状。方法于2008年,在10个氟中毒病区采用整群分层随机抽样的方法选择55个病区村分别调查水氟浓度、8～12岁儿童氟斑牙患病情况及尿氟浓度。结果在55个病区村中,轻、中、重病区的8～12岁儿童的氟斑牙检出率,差异有统计学意义(χ2=773.571,P=0.000),且与水氟呈正相关(r=0.924,P=0.000)。重病区不同年龄的儿童氟斑牙检出率差异具有统计学意义(χ2=16.351,P=0.003),儿童氟斑牙分度与尿氟呈正相关(r=0.251,P=0.000)。在30个病区村中,不同病区8～12岁儿童尿氟几何均数差异有统计学意义(H=75.356,P=0.000),且与水氟呈正相关(r=0.266,P=0.000)。但是,每个病区不同年龄的儿童尿氟几何均数差异无统计学意义(P>0.05)。结论天津市地方性氟中毒病情依然较重,尚未达到有效控制要求,需进一步落实防治措施和加强监测工作。Objective To know the epidemiological characteristics of children dental fluorosis in endemic fluorosis areas in Tianjin. Methods Ten prevalent areas were selected and 55 villages were collected by cluster sampling in 2008. Such indicators of endemic fluorosis as the content of water fluoride in the investigated villages, the state of dental fluorosis among the children aged 8-12 years, the concentration of urine fluoride were investigated. Results The average rates of dental fluorosis were different among different areas （Χ^2=773.571, P=0.000）, positively correlated with the content of water fluoride（r=0.924, P=0.000 ）. In serious prevalent areas, the average rates of dental fluorosis were different among age groups （Χ^2= 16.351, P=0.003）. The geometric mean of urine fluoride was different among different areas （H=75.356, P=0.000）, positively correlated with the content of water fluoride （r= 0.266, P=0.000）. In the same area, no significant difference was observed in the geometric mean of urine fluoride among age groups. Conclusion In Tianjin, endemic fluorosis is still very serious and the efficient control will be promoted.
