摘要: 目的 评估武汉市普通人群戊型病毒性肝炎病毒(戊型肝炎病毒,hepatitis E virus,HEV)感染状况及影响因素。方法 采用多阶段随机抽样方法,对抽取的3 890名0~59岁普通人群开展调查与血样采集,应用酶联免疫吸附法(enzyme-linked immunosorbent assay,ELISA)检测抗-HEV IgG,采用χ2检验、精确二项式公式法与非条件Logistic回归等方法进行统计学分析。结果 武汉市0~59岁普通人群抗-HEV IgG标化阳性率为35.01%,男性标化阳性率与女性的差异无统计学意义(χ2=3.18,P=0.075),随着年龄增长阳性率升高(χ2=542.32,P<0.001),城区人群标化阳性率高于郊区(χ2=11.32,P=0.001);18岁以上人群抗-HEV IgG多因素分析显示,男性、年龄较大者(30~59岁)、居住于城区、喜食鱼类的人群感染HEV的风险更高(均有P<0.05)。结论 武汉市普通人群HEV感染率较高,男性、年龄较大者(30~59岁)、居住于城区、喜食鱼类的居民是高危人群。Abstract: Objective To investigate the prevalence and risk factors of hepatitis E virus (HEV) infection among the general population in Wuhan. Methods Multi-stage random sampling method was adopted. A total of 3 890 general population aged 0 to 59 years were sampled, their serum samples were also collected and detected for anti-HEV IgG by ELISA. Chi-square test, exact binomial formula and unconditional logistic regression analysis were performed for statistical analysis. Results The standardized seroprevalence of anti-HEV IgG was 35.01%, which cumulated with age. The seroprevalence between male and female had no significant difference(χ2=3.18,P=0.075), the seroprevalence of elder (χ2=542.32,P<0.001)and residents in urban (χ2=11.32,P=0.001) were higher. Multivariate unconditional logistic regression analysis was performed among people over 18 years old, it showed that the male, elder (aged 30 to 59 years), urban residents and people having a preference of fish were at higher risk of HEV infection (all P<0.050). Conclusions The infection rate of HEV was high among the general population in Wuhan. The high-risk population were the male, elder (aged 30 to 59 years), urban residents and people having a preference of fish.
