目的了解深圳市孕产妇HBsAg携带情况,为预防控制乙肝母婴传播提供本底资料。方法孕产妇到助产机构产前检查或分娩时检测乙肝两对半,并将孕产妇基本情况及检测结果录入自主开发的专用信息管理系统,通过系统统计相关信息。结果深圳市2011-2013年孕产妇乙肝平均检测率为95.01%,孕产妇HBsAg三年平均阳性率为9.00%。<20年龄组孕产妇阳性率最低为7.05%,35岁以上年龄组孕产妇阳性率最高达9.61%。龙岗区孕产妇HBsAg阳性率最高达9.90%,最低南山区为8.17%。结论深圳市孕产妇HBsAg携带率较高,表明深圳仍为乙肝高流行地区,母婴阻断是预防控制乙肝的重要措施。

Objective To investigate the prevalence of maternal HBsAg carriers in order to establish basic information of the control and prevention on the mother-to-child transmission of hepatitis B. Methods Pregnant women were screened for hepatitis B sero-markers to identify their infectious status before delivery, and their screening results as well as demographic information were collected in the exclusive information management system developed by Shenzhen CDC that summarized relevant data. Results The average screening rate of pregnant women was 95.01%. The average prevalence of HBsAg in pregnant women in three years was 9.00%. The lowest prevalence of HBsAg was found in the 〈20 year group （7.05%）, while the highest prevalence was in the 35-39 year group （9.61%）. The prevalence of maternal HBsAg seropositivity was highest in the Longgang district （9.90%） comparing with other districts, while the lowest prevalence was in the Nanshan district （8.17%）. Conclusion Compared with other areas, the prevalence of maternal HBsAg carriers was high, which indicated that Shenzhen was the high endemicity areas in China. Therefore, it is crucial to interrupt the mother-to-child transmission of hepatitis B.
