目的了解重庆市涪陵区儿童流行性腮腺炎(腮腺炎)抗体水平,为制定腮腺炎防控措施提供参考。方法按地理位置,从5个不同方位监测点,分2~岁、6~岁和11~15岁3个年龄段,采取整群随机抽样法抽取2~15岁儿童全血3 230份,采用酶联免疫法检测腮腺炎病毒IgG抗体进行分析。结果重庆市涪陵区2~15岁儿童腮腺炎抗体阳性率为87.96%,不同监测点(χ2=111.156,P=0.000)、城区和乡镇间(χ2=11.929,P=0.001)腮腺炎抗体阳性率差异有统计学意义,不同年龄组(χ2=2.391,P=0.303)、不同性别间(χ2=1.765,P=0.184)腮腺炎抗体阳性率差异无统计学意义。结论重庆市涪陵区2~15岁儿童腮腺炎抗体阳性率总体保持在较高水平,但不同方位各监测点间、城区与乡镇间腮腺炎抗体阳性率仍然存在一定差距。应加强该区免疫水平较薄弱区域儿童腮腺炎的预防控制。
Objective To understand the prevalence of mumps (Mumps) antibody in children in Fuling District of Chongqing, and to provide reference for the development of mumps prevention and control measures. Methods According to geographical location, 3 230 monitoring points of children aged 2 ~ 15 years were collected by cluster random sampling method in 3 age groups of 2 ~ 6 years old and 11 ~ 15 years old from 5 different monitoring points. Mumps virus IgG was detected by enzyme-linked immunosorbent assay. Results The positive rate of mumps antibody was 87.96% in children aged 2-15 years in Fuling district of Chongqing Municipality. The positive rate of mumps antibody in urban and township (χ2 = 11.929, P = 0.001) was significantly higher at different monitoring sites (χ2 = 111.156, There was no significant difference in the positive rates of mumps antibody between different genders (χ2 = 1.765, P = 0.184) in different age groups (χ2 = 2.391, P = 0.303) Conclusions The positive rate of mumps antibody in children aged 2-15 years in Fuling District of Chongqing Municipality remains generally at a high level. However, the positive rate of mumps antibody between urban areas and townships still lags behind at different monitoring points. The prevention and control of mumps in children with weakened immune system in this area should be strengthened.
