目的调查南宁市高中学生复发性阿弗他溃疡患病情况，为该病的流行病研究提供理论依据。方法采用随机整群抽样的方法抽取南宁市2 107名高中生为研究对象，发放问卷调查，对其复发性阿弗他溃疡患病情况进行调查和分析。结果被调查的高中学生中复发性阿弗他溃疡的患病率28.17%，男生患病率为13.06%，女生患病率为15.11%，男、女生复发性阿弗他溃疡患病率差异无统计学意义。不同学校学生患病率有显著性差异（P＜0.05），在所调查的学生中，高中之前和升入高中后患病的比例分别是3.95%和23.83%，直系亲属中亦患有该病者和没患该病的比例分别为9.7%和18.47%。结论南宁市高中学生复发性阿弗他溃疡患病率较高，不同学校学生患病率有显著性差异，直系亲属中患有该病者，不会增加其患病率。

ObjectiveTo survey the incidence of recurrent aphthou ulcer among high school students of Nanning. MethodsA total of 2107 high school students were enrolled as the research subjects using random cluster sampling, then the incidence of recurrent aphthou ulcer were investigated and analyzed. ResultsThe incidence rate of recurrent aphthou ulcer among high school students of Nanning was 28.17%.Among them,the incidence rate of male was 13.06%,while female was 15.11%.There was no statistical difference between the incidence rate of male and female.But there was statistical difference between the incidence rate of difference schools (P＜0.05). Among them, 3.95% students suffered from recurrent aphthou ulcer before high school and 23.83% after high school.The immediate family members suffered from the disease and the proportion of not suffering from the disease were 9.7% and 18.47%,respectively. ConclusionsThe incidence rate of high school students of recurrent aphthou ulcer is high. Immediate family members of people with this disease would not increase the prevalence of students,and the prevalence of students increases greatly when they go to high school.
