口腔粘膜白斑病(简称白斑病)属癌前病变,受到世界各地的广泛重视。病例对照研究是研究病因的常用方法。许多现患调查已经发现吸烟与白斑病的联系,从而为研究病因提供了线索。本文目的是在现患调查的基础上,用病例对照的研究方法探讨吸烟与白斑病的病因关系。 资料与方法 我们根据1978年全国口腔粘膜病协作组制定的临床诊断标准,于1990年初,在某工厂对20岁以上职工的白斑病及吸烟史进行普查(吸烟者的标准是每天吸香烟一支,并长达一年以上者。不吸烟者包括戒烟一年以上者),共调查1913人。诊断标准由一人统一复查确诊,故误差较小。按研究目的进行资料审核,为尽可能排除混杂因素的干扰而删
Oral leukoplakia (referred to as vitiligo) is a precancerous lesion, widespread attention around the world. Case-control studies are the common method of studying etiology. Many current-risk surveys have uncovered links between smoking and vitiligo, providing clues to studying the cause. The purpose of this paper is to investigate the etiological relationship between smoking and vitiligo by using the case-control study on the basis of the prevalence survey. Materials and Methods According to the clinical diagnostic criteria developed by the National Cooperative Group of Oral Mucosal Diseases in 1978, we conducted a survey of vitiligo and smoking history of employees over the age of 20 in a factory in early 1990 (smokers' standard is to smoke cigarettes daily , And up to one year or more.Non smokers, including more than one year to quit smoking), a total of 1913 people surveyed. Diagnostic criteria by a unified review confirmed, so the error is small. According to the purpose of research data review, to eliminate as much as possible confounding interference factors deleted
