目的全面了解和掌握北京市昌平区本地户籍人群及外省市流动人群麻疹免疫状况,预测麻疹疫情,为实施有效的麻疹预防措施和控制策略提供科学依据。方法2004年8月~2005年9月对昌平地区部分本地户籍人口和外省市流动人口进行麻疹抗体水平调查。结果对本辖区227例户籍人口和218例流动人口进行抗体水平检测,麻疹抗体阳性率分别为61.23%和50.00%,两类人群抗体阳性率和抗体IgG水平差异均有统计学意义;两类人群中各年龄组间抗体阳性率结果差异均有统计学意义;不同性别人群抗体阳性率结果差异均无统计学意义。结论昌平区户籍人口及流动人口,特别是计划免疫外年龄组人群的抗体阳性率较低,结合昌平地区麻疹疫情情况,今后的麻疹控制重点应以麻疹计划免疫外人群为主,加强宣传,做好成人及外来人口的免疫接种工作。
OBJECTIVE To understand and grasp the status of measles immunity in local population of permanent residents and other floating population in Changping District of Beijing and predict the epidemic situation of measles so as to provide a scientific basis for implementing effective measles prevention measures and control strategies. Methods From August 2004 to September 2005, the level of measles antibody in some local permanent residents and other provinces in Changping area was investigated. Results The antibody levels of 227 registered permanent residents and 218 floating population were detected in this area. The positive rates of measles antibody were 61.23% and 50.00% respectively. There was significant difference between the two groups in antibody positive rate and IgG antibody level. Among the two groups The antibody positive rate among different age groups had statistically significant difference. There was no significant difference in antibody positive rate among different sex groups. Conclusion The prevalence of census of population and floating population in Changping District, especially in the population outside the planned immunization group is relatively low. Based on the epidemic situation of measles in Changping District, the focus of measles control in the future should be mainly immunized with measles immunization program, Good adult and immigrant population immunization.
