福州市2007年流动人口麻疹和风疹抗体水平监测

Analysis on measles and rubella antibody levels in migrant population in Fuzhou City,2007

目的了解福州市流动人群的麻疹和风疹抗体水平,为麻疹和风疹的预防控制工作提供依据。方法采用酶联免疫吸附试验检测随机调查的0~44岁477名流动人群麻疹和风疹IgG抗体。结果流动人群麻疹抗体阳性率81.34%,风疹抗体阳性率80.71%;不同年龄组流动人群麻疹抗体水平差异无统计学意义(χ2=0.760,P】0.05),≤15岁流动人群风疹抗体阳性率低于】15岁年龄组(χ2=49.483,P【0.01);城区流动人群麻疹抗体水平低于农村(χ2=15.478,P【0.01),城乡风疹抗体水平差异无统计学意义(χ2=0.049,P】0.05);流入时间小于1年流动人口麻疹抗体水平高于流入时间大于1年人群(χ2=5.342,P【0.05),省外流入人群麻疹抗体水平高于本省其他地市和本市其他区县(χ2=7.208,P【0.05),风疹抗体水平均差异无统计学意义(χ2=0.017,P】0.05;χ2=0.089,P】0.05)。结论福州市控制麻疹和风疹的重点人群仍为15岁以下特别是1.5岁以下人群,在做好基础免疫基础上,应大力开展麻疹和风疹的强化免疫,特别是流动人口的强化免疫。

Objective To investigate the levels of measles and rubella antibodies in migrant population of Fuzhou City and to formulate the immunization strategies of measles and rubella.Methods The measles and rubella antibodies of migrant population aged 0-44 years were detected by a ELISA method.Results The seropositive rate of measles antibody was 81.34%,and the seropositive rate of rubella antibody 80.71%.There were no significant differences in seropositive rate of measles antibody among different age groups(χ2=0.760,P>0.05).The seropositive rate of rubella antibody was significantly lower in the migrant population below 15 years of age than in those above 15 years of age(χ2=49.483,P<0.01);the seropositive rates of measles and rubella antibodies was significantly lower in the urban migrant population than in rural ones(χ2=15.478,P<0.01).There was no significant difference in seropositive rate of rubella antibody between the urban and rural areas(χ2=0.049,P>0.05).The seropositive rate of measles was significantly higher in the migrant population whose relocation time was less than one year than in those whose relocation time was more than one year(χ2=5.342,P<0.05).The seropositive rate of measles was signiflcantly higher in the migrant population who come from the other provinces than in those who come from Fujian Province(χ2=7.208,P<0.05).Conclusion The children under 15 years of age,especially those below 1.5 years,are the main target groups of measles and rubella control.It is important to conduct the supplementary immunization activity of measles and rubella vaccine in migrant population.
