摘要
本文报告了医院与普通人群甲、乙型病毒性肝炎病例对照研究中同时使用普通对照与易感者对照时,两种对照的免疫水平与暴露率对OR值的影响作用.结果表明:从免疫水平看,抗HAV阳性率在80.5%或92.3%、HBV感染在47.5%的情况下,普通对照和易感者对照的OR值,除个别发病因素(甲肝的不洁饮食史)外,基本无显著差异.再从暴露率来看,两种对照除个别因素外暴露率均无显著差异(x^2<3.84,P>0.05),OR值的95%CI也相互交叉.从而可初步认为在病毒性肝炎病例对照研究中使用普通对照与易感者对照都是合理的.
When the general individual and susceptible individual controls were simultaneously studied in case-control study of viral hepatitis among hospital and general population,we analysed the similarities and differences between OR valuls of the two controls for risk factors of HA and HB.The results showed,when the positive rate of the anti-HAV was 80.5% or 92.3%,and the infective rate of HBV was 47.5%,that OR values of the risk factors between the general and susceptible controls were not significantly different.The exposure rates of the two controls were also not significantly different (x^2<3.84,P>0.05) except for one or two risk frctors,and 95% CI of the OR values crossed each other.So,it is preliminarily suggested that in case-control study of viral hepatitis either general control or susceptible control could be used.
