摘　　要：目的了解江门市各年龄段人群甲型H1N1流感病毒抗体水平,为完善甲型H1N1流感疫情防控措施提供科学依据。方法采取多阶段分层随机抽样方法抽取研究对象480人,进行血清标本采集和问卷调查,应用红细胞血凝抑制方法检测甲型H1N1流感病毒抗体。结果人群甲型H1N1流感病毒抗体阳性率为19.38%,0～、6～、16～、25～和60岁以上组的甲型H1N1流感病毒抗体阳性率分别为22.09%、27.36%、24.47%、14.58%和8.16%。6～24岁的甲型H1N1流感病毒抗体阳性率较高,为51.83%,无症状抗体阳性率达12.61%。抗体阳性率在不同年龄、性别和职业上差异均有统计学意义(P<0.05)。结论江门市甲型H1N1流感病毒感染状况各年龄段不同,青少年抗体阳性率较高,老年人抗体阳性率相对较低,男性抗体阳性率高于女性。Objective to investigate the antiviral antibody levels of different age groups of influenza A（H1N1） infected residents in Jiangmen Ctiy,and provide scientific basis for setting strategies and measures for prevention and control of influenza A（H1N1） epidemic.Methods 480 persons were recruited by multi-stage stratified random sampling.The hemagglutination inhibition test was conducted to detect influenza A（H1N1） infection.Results The overall positive rate of influenza A（H1N1） antibody was 19.38%,in which 22.09% in 0～ age group,27.36% in 6～ age group,24.47% in 16～ age group,14.58% in 25～ age group,and 8.16% in over 60 age group.Influenza A（H1N1） infection occurred mainly in the 6～24 age group,with the positive rate of 51.83%.The latent infection rate was up to 12.61%.And the difference of influenza A（H1N1） antibody positive rates between different age groups,genders and jobs were statistical significant（P0.05）.Conclusion The positive rate of influenza A（H1N1） virus infection is different in different age group,higher in younger people and lower in elder people.The positive rate of male group was higher than that of female group.
