高氟与视力关系的研究

Study of relation between high - fluorine and vision

目的 研究高氟与视力的关系，探讨高氟对视力的作用机制。方法 以高氟区少年儿童作为研究对象，以低氟地区少年儿童作为对照，按照统一方法检测视力，用Ｘ２检验方法作显著性检验。结果 视力不良率高氟区低于低氟区，差异显著（Ｐ＜０．０５）；两区少年儿童的视力差异主要表现在女性和１２～１３岁年龄组。结论 高氟对少年儿童的视力减退具有一定的抑制作用，说明高氟对视力有保护作用。

Objective To study the effects of high - fluorine on the vision of children. Methods By using the same method, the vision of children from high - fluorine area were tested and compared with children from low - fluorine area. The test for obvious result was conducted with the t - test. Results The rate of bad vision in children from high - fluorine area lower than that of control and difference was obvious (P <0. 05). In the girl 12~13 yeras old group, the difference in vision between children from high - fluorine area and those from low - fluorine area was obvious. Conclusion The high - fluorine can promote and protect children vision.
