深圳市外来劳务工风疹病毒抗体水平调查

Rubella antibody level among immigrant workers in Shenzhen

目的了解广东省深圳市外来劳务工中风疹病毒抗体水平,为制定风疹防控策略提供依据。方法采用分层随机抽样调查方法 ,对深圳市外来务工人员1 003人进行问卷调查并采集血液样本,采用酶联免疫吸附法（ELISA）检测血清中风疹IgG抗体。结果深圳市外来劳务工风疹病毒抗体（IgG）阳性率为75.37%;其中20~40岁女性阳性率为76.1%,低于其他年龄组女性的87.3%,差异有统计学意义（2χ=4.470,P=0.034）;来自不同省份的劳务工抗体阳性率差异有统计学意义（2χ=16.7067,P=0.006）。结论深圳市外来劳务工年轻群体和育龄妇女群体的风疹病毒抗体（IgG）阳性率较高,应加强外来劳务工中育龄妇女的风疹监测和疫苗接种。
