乙型肝炎感染危险因素的多因素分析

目的了解不同人群乙肝病毒感染现状,分析乙肝病毒感染的相关危险因素。方法按照全国疾病监测点总体调查抽样方案的要求,进行入户个案调查乙肝感染相关行为危险因素,并采血检测HBV感染情况。调查数据用SPSS 13.0软件进行分析。结果口腔诊疗史（OR=1.498）、输血史（OR=1.434）和创伤性美容史（OR=2.132）是本次调查所得乙肝感染的主要危险因素。不同职业人群存在统计学差异（χ2=364.69,P〈0.001）,工人感染率最高,达到74.14%,不同文化程度人群中以高中（中专）感染率（63.33%）为最高（χ2=221.74,P〈0.001）。乙肝疫苗接种具有良好的保护效果（χ2=318.93,P〈0.001）。结论在重点人群中开展健康教育、改变不正确的行为、掌握正确的防治方法、实施免疫接种是预防控制乙肝的重要措施。

Multi-variable analysis an risk factors of hepatitis B

Objective To study the infection situation of HBV among different kinds of persons and the risk factors of HBV infection. Methods A family investigation was carried out to gather the data about the risk factors of HBV infection-related behavior based on the national disease surveillance sam- piing method and gathering the serum to test the situation of HBV infection. The method of data analysis was χ2 test and logistic by SPSS 13.0. Results The consistent 3 risk factors were： actinal indagation and therapy （ OR = 1. 498） ; blood transfusion （ OR = 1. 434） ; traumatogenic beauty treatment （ OR = 2. 132）. These factors were the main risk factors of HBV found from the investigation. The difference of HBV infection among people with different jobs and education were significant （χ2 = 364.69, P 〈 0. 001 ;χ2 = 221.74, P 〈 0. 001 ）. The workers （74.14 % ） and high-school educated people （63.33 % ） were the highest individually. The immunization had good protection （χ2=318. 930 ,P〈0. 001 ）. Conclusions Health education of HBV should be enhanced for these key people to change their wrong behaviors and give them the right knowledge of prevention and control of HBV. Immunization of these people is also important to control and prevent HBV infection.
