摘要
目的 查明饮茶型氟骨症病情与砖茶摄入量的剂量反应关系。方法 在我国南、北方各选 1个典型饮茶型氟中毒病区 ,四川省阿坝县和内蒙陈巴尔虎旗 ,用 X线方法诊断氟骨症患者 ,用回顾性研究方法调查患者从饮砖茶中氟摄入量。结果 阿坝县的 、 、 度氟骨症患者从饮砖茶中日人均氟摄入量分别为 6 .2 6、9.92和 12 .80mg;陈旗的 、 度氟骨症患者从饮砖茶中日人均氟摄入量分别为 6 .2 6、10 .2 3mg,未发现 度氟骨症患者 ;病情与年人均砖茶消耗量呈线性关系 (F =330 .2 5 ,P <0 .0 1) ,相关系数为 0 .77。结论 氟骨症患者的病情与从饮砖茶中氟摄入量呈正相关剂量反应关系。
Objective To clarify the dose-response relationship between skeletal fluorosis state and amount of brick tea intake.Methods One of typical fluorosis areas of drinking brick-tea type was selected in north of China,and one in south of China,which are situated in Aba county of Sichuan province and Chenbaerhuqi of the Inner Mongolia Autonomous Region,respectively.Skeletal fluorosis was diagnosed with x-ray technology.The data of brick-tea consumption was obtained with retrospective survey.Results In Aba county,mean of brick tea fluoride absorbed by the patients with first,second and third degrees of skeletal fluorosis a day were 6.26,9.92 and 12.80mg,respectively.In Chenbaerhuqi county,mean of brick tea fluoride absorbed by the patients with first and second degrees of skeletal fluorosis a day were 6.62 mg and 10.23 mg,respectivey,but none of third degree of skeletal fluorosis patients were found.There was a linear-correlation relationship between skeletal fluorosis state and an average amount of brick tea consumption per man a year (F=330.25,P<0.01),and the coefficient of correlation is 0.77.Conclusion There was a positive correlative dose-response relationship between skeletal fluorosis state and amount of brick tea intake.
