目的为了解深圳市松岗社区居民乙型肝炎病毒感染的现状,分析乙肝病毒感染血清标志分布情况。方法以社区为单位,采用整群抽样方法,抽取某社区,将该社区1～59岁居民共459例组成样本。以ELISA方法对血清标本统一检测乙肝病毒标志物,包括乙肝表面抗原(HBsAg)、乙肝表面抗体(抗-Hbs)、乙肝核心抗体(抗-Hbc)。结果调查人群中HBsAg、抗-Hbs、抗-Hbc阳性率及HBV感染率分别为9.80%、70.59%、62.96%、62.75%。男性的HBsAg阳性率高于女性,但差异无统计学意义(χ2=2.914,P>0.05);青壮年感染水平较其他年龄组高,不同年龄组HBsAg感染率差异有统计学意义(χ2=11.678,P<0.05);农民和私营业主的HBsAg阳性率高于其他职业,不同职业的HBsAg阳性率差异有统计学意义(χ2=101.23,P<0.05)。结论应继续加大对乙型肝炎的防控力度,加强宣传教育,提高自我保护意识。扩大疫苗接种范围,提高人群总体免疫水平。 Objective To understand the current status of hepatitis B virus infection in Shenzhen Songgang community residents and analyze the distribution of serum markers of hepatitis B virus infection. Methods Community-based, cluster sampling method was used to extract a community, a total of 459 residents aged 1-59 in the community sample. Serum samples were detected by ELISA for the detection of hepatitis B virus markers, including HBsAg, HBsAg and anti-HBc. Results The positive rates of HBsAg, anti-Hbs, anti-Hbc and HBV infection in the survey population were 9.80%, 70.59%, 62.96% and 62.75% respectively. The positive rate of HBsAg in males was higher than that in females, but the difference was not statistically significant (χ2 = 2.914, P> 0.05). The infection rate in young adults was higher than that in other age groups. The infection rates of HBsAg in different age groups were statistically significant (χ2 = 11.678 , P <0.05). The positive rate of HBsAg of peasants and private owners was higher than that of other occupations. The positive rates of HBsAg in different occupations were statistically significant (χ2 = 101.23, P <0.05). Conclusion The prevention and control of hepatitis B should continue to be strengthened, publicity and education should be stepped up, and awareness of self-protection should be enhanced. Expand the scope of vaccination, improve the overall level of population immunity.
