[目的]了解广州市荔湾区健康人群麻疹免疫状况,评价麻疹疫苗的接种质量和效果,为制定和调整免疫策略提供依据。[方法]2009年10～12月,在广州市荔湾区抽取部分健康人群进行血清麻疹IgG抗体水平检测。[结果]检测健康人群240人,麻疹抗体阳性的224人,阳性率为93.33%,保护率为65.83%;几何平均滴度(GMT)为1∶1044。抗体阳性率,男性为90.40%,女性为96.52%(P>0.05);<1、1～2、3～4、5～6、7～10、11～14、15～19、>20岁分别为81.82%、100.00%、100.00%、100.00%、96.67%、94.29%、86.11%、89.47%(P<0.05);站前街为93.33%,茶滘街为93.33%(P>0.05)。不同年龄组抗体滴度差异有统计学意义(P<0.05)。[结论]荔湾区麻疹IgG抗体<1岁组及>15岁组抗体阳性率较低。
[Objective] To understand the immune status of measles in healthy population in Liwan District of Guangzhou and evaluate the quality and effectiveness of measles vaccination in order to provide a basis for formulating and adjusting immunization strategies. [Methods] From October to December 2009, serum samples of measles IgG were detected in some healthy people in Liwan District of Guangzhou City. [Results] A total of 240 healthy people were detected in this study. The positive rate of measles antibody was 224.33%. The positive rate was 93.33%. The protective rate was 65.83%. The geometric mean titer (GMT) was 1:1044. The positive rate of antibody was 90.40% in males and 96.52% in females (P> 0.05). The positive rate of antibody was <1,1 ~ 2,3 ~ 4,5 ~ 6,7 ~ 10,11 ~ 14,15 ~ 19,> 20 years old respectively Were 81.82%, 100.00%, 100.00%, 100.00%, 96.67%, 94.29%, 86.11%, 89.47%, respectively (P <0.05). The antibody titers in different age groups had statistical significance (P <0.05). [Conclusion] The antibody positive rate of measles IgG antibody in Liwan District was lower than that in patients <1 year old and> 15 years old.
