目的了解辽宁省监狱人群病毒性乙型肝炎(乙肝)感染状况。方法随机抽取辽宁省5所监狱在押犯人4372人,干警353人为调查对象,采用酶联免疫吸附试验(ELISA)方法检测血清乙肝标志物。结果监狱人群乙肝病毒表面抗原(HBsAg)阳性率为8.37%,其中犯人8.66%、干警5.10%。5所监狱人群中HBsAg携带率均接近或低于辽宁省正常人群,统计学检测差异无统计学意义(χ2=0.81,P>0.05)。犯人间各年龄组HBsAg检出率差异无统计学意义;各年龄组干警间HBsAg检出率差异有统计学意义(χ2=44.85,P<0.05)。犯人,干警男、女性别间差异均无统计学意义。HBsAg、乙肝病毒e抗原和乙肝病毒核心抗体均为阳性的87人,其中犯人85人,占总调查人数的2.11%,干警2人,占总调查人数的0.79%。结论本次调查结果显示,辽宁省监狱在押犯人HBsAg阳性率与正常人群差异无统计学意义。 Objective To understand the status of viral hepatitis B (hepatitis B) infection in prisons in Liaoning Province. Methods A total of 4372 prisoners in 5 prisons in Liaoning Province were randomly selected and 353 police officers were investigated. Enzyme linked immunosorbent assay (ELISA) was used to detect serum hepatitis B markers. Results The positive rate of hepatitis B virus surface antigen (HBsAg) in prison population was 8.37%, including 8.66% of prisoners and 5.10% of police officers. The carrying rates of HBsAg in 5 prisons were all close to or lower than those in Liaoning Province. There was no significant difference in statistical test (χ2 = 0.81, P> 0.05). There was no significant difference in the detection rate of HBsAg between prisoners in all age groups. The detection rate of HBsAg among police officers in each age group was significantly different (χ2 = 44.85, P <0.05). Prisoners, police officers male and female differences were not statistically significant. HBsAg, hepatitis B virus e antigen and hepatitis B virus core antibody were positive in 87 people, of which 85 prisoners, accounting for 2.11% of the total number of investigators, police 2, accounting for 0.79% of the total number of inquiries. Conclusion The survey results show that there is no significant difference in the positive rate of HBsAg among prisoners in Liaoning Province and the normal population.
