[目的]了解大连市自然人群HBV感染状况及感染模式。[方法]2008年6~10月,在大连市城乡抽取900名自然人群进行血清HBV感染标志物检测。[结果]检测900人,检出HBV感染者339人,感染率为36.67%。其中,HBsAg、抗-HBs、抗-HBc、HBeAg、抗-HBe阳性率分别为7.11%、41.22%、22.67%、2.89%和10.44%。580名无乙肝疫苗接种史者中,单纯抗-HBs阳性的占12.59%,抗-HBS、抗-HBC阳性的占9.14%,单纯抗-HBc阳性的占7.41%,HBeAg、抗-HBC、抗-HBe阳性的占2.59%,HBeAg、抗-HBC、HBeAg阳性的占1.38%,抗-HBS、抗-HBC、抗-HBe阳性的占5.52%,5项均阴性的占50.17%。[结论]大连市自然人群HBV感染率不高,近一半的人已获得抗-HBs。
[Objective] To understand the HBV infection status and infection pattern of natural population in Dalian. [Methods] From June to October 2008, 900 natural populations in urban and rural areas of Dalian were collected to detect serum HBV infection markers. [Results] The detection of 900 people, detected 339 people infected with HBV, the infection rate was 36.67%. The positive rates of HBsAg, anti-HBs, anti-HBc, HBeAg and anti-HBe were 7.11%, 41.22%, 22.67%, 2.89% and 10.44% respectively. Of the 580 patients who did not have a history of hepatitis B vaccination, anti-HBs alone accounted for 12.59%, anti-HBs, anti-HBC positive accounted for 9.14%, anti-HBc positive accounted for only 7.41%, HBeAg, anti-HBC, anti -HBe positive accounted for 2.59%, HBeAg, anti-HBC, HBeAg positive accounted for 1.38%, anti-HBS, anti-HBC, anti-HBe positive accounted for 5.52%, 5 were negative accounted for 50.17%. [Conclusion] The HBV infection rate of natural population in Dalian is not high, and nearly half of them have acquired anti-HBs.
