摘要
[目的]了解济宁市农村学龄儿童地方性氟中毒患病现状,为制定防病对策提供科学依据。[方法]在饮水含氟量超过我国生活饮用水卫生标准水氟限值的嘉祥县、金乡县各抽取1所乡镇中心小学,对五、六年级在校学生进行调查。[结果]调查486名,氟斑牙阳性率为52.06%,氟斑牙指数为1.02。氟斑牙阳性率嘉祥县、金乡县分别为62.74%、43.80%(P<0.01)。男性、女性分别为54.58%、49.36%(P>0.05)。检测97名儿童,尿氟值(几何均值±标准差)为(0.93±0.77)mg/L,超过8～12岁儿童尿氟均值的占46.39%。尿氟值嘉祥县37人为(0.97±0.48)mg/L,金乡县60人为(0.91±0.90)mg/L(P>0.05)。[结论]济宁市两县农村学龄儿童氟斑牙阳性率较高,地方性氟中毒病情尚未有效控制。
[Objective]To understand the prevalence of endemic fluorosis among rural school-age children in Ji＇ning city, and provide a scientific basis for making prevention and control countermeasures. [Methods]Investigation was conducted in primary school students in grade 5 and 6 selected from 1 town central primary school each from Jiaxiang and Jinxiang county where the content of fluoride in drinking water exceeded the limited value based on National Hygienic Standard for Drinking water. [Results]Of the 486 children investigated,the positive rate of dental fluorosis and dental fluorosis index were 52.06% and 1.02. The positive rate of dental fluorosis in Jiaxiang and Jinxiang county was 62.74% and 43.80% respectively（ P 〈0. 01） ,54.58% and 49.36% in male and female children respectively（ P 〉0.05）. Of the 97 children tested,the fluoride value in urine（geometric mean ± standard deviation） was （0.93 ±0.77） mg/L, 46.39 % of the children aged from 8-12 exceeded the fluorine mean value in urine. The fluoride value in urinary in Jiaxiang （37 children） and Jinxiang（60 children） was （0.97±0.48） mg/L and （0.91±0.90） mg/L respectively（ P 〉0.05）. [Conclusion]The positive rate of dental fluorosis of rural school-age children was higher in Jiaxiang and Jinxiang counties, the prevalence of endemic fluorosis was not effectively controlled.
