宁夏2010年健康人群麻疹抗体水平监测分析

Analysis of measles antibody among healthy population in Ningxia in 2010

目的了解宁夏健康人群麻疹免疫状况。方法采用分层随机抽样的方法,按照不同地区选择调查对象,应用酶联免疫吸附试验对1 209例健康人群血清进行麻疹IgG抗体水平监测。结果宁夏健康人群麻疹抗体阳性率为97.85%,不同地区阳性率差异有统计学意义;大年龄组人群抗体水平有降低的趋势(χ2=5.744,P=0.017),不同性别、民族和户籍人群抗体水平差异无统计学意义。结论宁夏健康人群麻疹抗体水平较高,但要加强对抗体水平较低地区的督查,重点关注农村成人以及流动人口。

Objective To investigate the immune level of measles immune antibody level among healthy people in Ningxia province. Methods Selected the objects from different areas using stratified random sampling and tested IgG antibody by ELISA assay for 1209 healthy people. Results The result showed that the positive rate of measles antibody was 97.85%. The difference of measles antibody positive rate between different counties was statistically significant （ P 〈 0.05 ）. The tendency of adult antibody level presented descend （ r = 0. 069, P = 0.017 ）. There was no statistically significant （ P 〉 0.05 ） among different gender, national and state of census register. Conclusion The seropositive rate among healthy people in Ningxia is higher enough to prevent outbreak and epidemic of mea-sles. In order to prevent and control measles in the future, we should be strengthen the supervision to the high - risk areas, and pay more attention to the rural adults and floating population.
