福建省育龄妇女麻疹抗体水平监测分析

Surveillance analysis on measles antibody level of child-bearing age women in Fujian

目的了解福建省育龄妇女麻疹抗体水平。方法随机抽取4个县(区)1 904人育龄妇女进行麻疹IgG抗体检测。结果育龄妇女麻疹IgG抗体阳性率89.9%,几何平均滴度(GMT)333.03IU/mL。有免疫史者抗体阳性率比无免疫史者高,实施计划免疫前出生的育龄妇女,抗体阳性率比计免后出生者高;沿海与山区、有麻疹病史与无麻疹病史者抗体阳性率类似。结论育龄妇女有麻疹疫苗免疫史和年龄较大者,对麻疹IgG抗体水平有正向影响。

Objective To study measles antibody level of child-bearing age women in Fujian. Methods Totally 1 904 child- bearing age women were selected randomly from the residents in 4 counties and the measles IgG antibodies were detec- ted by ELISA methods. Results The antibody positive rate of measles in the women was 89.9%, the GMT was 333.03 IU/mL. The antibody positive rate of the women with measles vaccination was higher than that of no vaccination. And the positive rate of the women born before expanded program on immunization （EPI） was higher than that of after EPI. The antibody positive rate of the women in coastal areas was similar to the women in mountainous areas, and the rate of suffering from measles was similar to no measles history. Conclusion The child-bearing age women with measles vaccination and older age groups show positive influence on IgG antibody level of measles.
