【摘要】 目的 探讨深圳市一般人群中输血传播病毒(TTV)感染情况及其影响因素。方法 采用多阶段随机抽样抽取研究对象，并用套式聚合酶链反应法(nPCR)检测该人群血清中TTVDNA。结果 深圳市一般人群中TTV DNA总阳性率为11.86%，男女阳性率分别为14.67%和9.41%；年龄组间TTVDNA阳性率差异无显著性，单因素和logistic回归分析未显示肝病史、近期手术史、注射史、拔牙史及乙型肝炎疫苗接种等因素与TTVDNA感染有关；HBsAg、抗-HBs和抗-HBc与TTV感染无统计学意义。但不同职业人群TTVDNA阳性率差异有显著性，地税干部和中小学教师TTV DNA阳性率高于其他人群。结论 深圳市一般人群中TTV感染率较高，尤其是地税干部和中小学教师，但其流行因素尚需进一步研究。

【 Abstract】 Objective To explore the prevalence of transfusion transmitted virus (TTV)infection and its risk factors among the general population in Shenzhen. Methods Based on the multi-stagesampling,320 subjects were selected randomly and tested for TTV DNA in sera using a nestedpolymerase chain reaction (nPCR). Results The prevalence rate of TTV DNA was 11.86% in thepopulation (14.67% for male and 9.41% for female,respectively). There was no significantdifference between males and females, nor with different age groups. The histories ofhepatitis, surgical dental operations and injections were not associated with TTV DNAinfection. Hepatitis B vaccination and positivity of HBsAg,anti-HBs and anti-HBcantibodies were not related to TTV DNA prevalence rate. However,the significantdifferences were found in the prevalence rates of various professional groups. It washigher in tax collectors and teachers of primary and middle schools as compared with otherprofessional groups. Conclusion The prevalence of TTV DNA seemed to be high among thegeneral population in Shenzhen,especially in tax collectors and teachers of primary andmiddle schools. The risk factors of TTV infection in the population need to be furtherstudied.
