复发性阿弗他溃疡相关危险因素的病例对照研究

Case-control study on risk factors of recurrent aphthous ulcer

目的 :通过病例对照研究,调查复发性阿弗他溃疡(recurrent aphthous ulcer, RAU)发生的可能危险因素。方法 :对113例RAU患者、102例非RAU患者进行问卷调查,包括系统疾病、吸烟、饮酒、居住地改变、饮食、心理因素等58项内容,采用SPSS23.0软件包对各个相关因素进行Logistic回归分析,筛选出RAU的致病高危因素,并进行趋势分析。结果:单因素分析显示,居住地改变、亲属患病、胃肠道症状(疾病)、月经相关、软垢、结石和焦虑等是RAU患病的关联因素。多因素非条件Logistic回归显示,亲属易患病、大量口腔结石是RAU患病的危险因素。趋势χ2分析发现,蔬菜的种类、软垢的量与RAU存在等级效应关系,蔬菜的摄入种类越少,口腔内软垢、结石的量越多,RAU的患病危险性越高(P<0.05)。结论:RAU的发生是消化系统、遗传系统、免疫系统、口腔微环境"多联因素"综合作用的结果。

PURPOSE: To evaluate the risk factors for the occurrence of recurrent aphthous ulcer(RAU) in Fuzhou city by case-control study. METHODS: A questionnaire survey of 113 patients with RAU and 102 non-RAU patients in the same hospital was made, including 58 items. Chi-square test and conditional logistic regression were used for monovariate and multivariate analysis respectively with SPSS23.0 software package. RESULTS: One-way Chi-square test showed that immigrants, genetic factors, gastrointestinal disorders, menstrual period, oral health status, anxiety were related factors for patients suffering from RAU. Conditional logistic regression analysis indicated that genetic factors as well as more dental calculus in the oral cavity were RAU risk factors. Tendency Chi-square test revealed that there was a negative correlation between the occurrence of RAU and vegetable intake, and a positive correlation with the amount of dental calculus and soft scale in the oral cavity. CONCLUSIONS: The occurrence of RAU is the result of combination of "multiple factors" in the digestive system, genetic system, immune system and oral microenvironment.
