摘要
目的了解2012年北京市密云县健康人群的麻疹抗体水平。方法按照地理位置、人口构成随机抽取密云县9个接种单位的10个行政村（居委会）为监测点，选择在当地连续居住6个月以上的健康人群，分10个年龄组，共采集静脉血标本268份，男、女性别比例在0．8～1.2之间。结果此次麻疹抗体阳性率为88．43％；几何平均滴度（GMT）为1532．4IU／L。不同年龄抗体阳性率差异有统计学意义（χ^2=126．405，P=0．000），不同年龄的GMT差异有统计学意义（F=5．337，P=0．000）。结论密云县健康人群麻疹抗体阳性率、GMT总体保持在较高水平，0～7月龄婴儿麻疹抗体的低阳性率反应出部分成人抗体较低，因而小月龄婴儿获得的母传抗体随之较低。
Objective To understand antibody level of measles in healthy population in Miyun county of Beijing in 2012. Methods According to the geographical location and demographic,10 administrative villages （neighborhood committees） in Miyun county were randomly celected for monitoring. Healthy people who had lived in the local continuously for 6 months or more were recruited and divided into 10 groups. Sex ratio of male to female is 0. 8 to 1.2. A total of 268 venous blood samples were collected. Results Positive rate of measles antibody was 88.43% ; The GMT was 1532.4 IU/L. The difference of antibody positive rate between different age group was statistically significant （chi-square = 126.405, P = 0. 000） , the difference of GMT between different age group was statistically significant （ F = 5. 337, P = 0.000）. Conclusion Measles antibody positive rate and GMT in healthy people in Miyun county remains generally at a higher level, low positive rate of measles antibodie in group of 0 to 7 months baby suggests that antibody level in some adult is low, therefore babies get less antibody from their mother.
