[目的]了解大连市健康人群麻疹抗体水平,为制定免疫策略和评价免疫效果提供依据。[方法]2007年,在大连市所辖10个区(市、县)抽取部分健康人群检测血清麻疹IgG抗体水平。[结果]检测1439人,血清麻疹IgG抗体阳性率为97.64%,抗体几何平均滴度(GMT)为1∶4091。麻疹抗体阳性率,男性与女性、7个年龄组均在96%以上(P>0.05);麻疹抗体阳性率,城区低于城郊结合部和农村(P<0.01或P<0.05);抗体几何平均滴度,城区和农村低于城郊结合部(P<0.01)。[结论]2007年大连市人群麻疹抗体水平处于较高水平,城区人群低于农村人群。
[Objective] To understand the level of measles antibody in healthy population in Dalian, and provide basis for developing immunization strategy and evaluating immune effect. [Methods] In 2007, serum levels of measles IgG were detected in some healthy people in 10 districts (cities and counties) under the jurisdiction of Dalian. [Results] The positive rate of serum anti-measles IgG antibody was 97.64% and the geometric mean antibody titer (GMT) was 1,4091. The positive rate of measles antibody in male and female patients was over 96% in 7 age groups (P> 0.05). The positive rate of measles antibody in urban areas was lower than that in suburbs and rural areas (P <0.01 or P <0.05) Titers in urban areas and rural areas were lower than those in suburban areas (P <0.01). [Conclusion] The measles antibody level of Dalian population was at a high level in 2007, and the urban population was lower than that of rural population.
