2012年北京市平谷区健康人群风疹抗体水平监测结果

目的了解北京市平谷区健康人群风疹抗体水平，为传染病防控工作提供科学依据。方法在平谷区10个行政村（居委会）按照随机方法抽取样本，采集血标本，采用酶联免疫吸附试验（ELISA）检测风疹抗体，同时调查风疹患病史和免疫史及人口学特征。结果全区共检测251人，阳性率为82．07％，不同免疫史人群风疹抗体阳性率差异有统计学意义（x^2=33．19，P〈0．01）；0～7月龄组阳性率最低，6～9岁组阳性率最高，不同年龄组人群风疹抗体阳性率差异有统计学意义（x^2=46．18，P〈0．01）；不同性别、户籍、职业人群风疹抗体阳性率差异无统计学意义。结论提高麻风二联和麻腮风三联疫苗基础免疫，对控制风疹疫情有重要意义；另外，育龄期妇女在孕前接种风疹疫苗是有必要的。

Monitoring results of rubella antibody level of healthy people in Pinggu District of Beijing City in 2012

Objective] To understand the rubella antibody level of healthy people in Pinggu District of Beijing City , and provide scientific evidence for infectious disease control. Methods] Samples were selected according to random method from 10 administra- tive villages （ neighborhood committees ）. Rubella antibody was detected by using enzyme-linked immunosorbent （ ELISA ）. Mean- while, the rubella disease history, immunization history and demographic characteristics were investigated. Results] A total of 251 people were detected, the positive rate was 82.07%. The antibody positive rate was significantly different between people with dif- ferent rubella immunization history （ x^2 = 33.19, P 〈 0.01 ）. The positive rate of 0 - 7 months group was lowest, that of 6-10 years was highest. The rubella antibody positive rate was significantly different between age groups. （x^2 = 46.18 ,P 〈 0.01 ）, while that was not significantly different between genders, household registrations and professionals. Conclusion] It was important to control rubella outbreak via improving basic immunization of MR and MMR vaccine. Additionally, it was necessary to vaccinate childbear- ing age women before pregnancy, leprosy and ma gills wind based immune sanlian vaccine.
