[目的]了解太原市健康人群麻疹抗体水平,为有针对性地制定防制措施及为在2012年全市消除麻疹做好前期准备工作。[方法]2007年4～5月,在太原市辖区内抽取部分3～59岁6个年龄组的健康人群进行麻疹血清抗体检测。[结果]检测2 648人,麻疹血清抗体阳性的2 557人,阳性率为96.56%,几何平均滴度(GMT)为1∶2 250。抗体阳性率,男性为96.12%,女性为96.98%(P>0.05);抗体GMT,男性为1∶2 034,女性为1∶2 473(P<0.05)。抗体阳性率,3～4岁为95.74%、5～7岁为96.41%、8～15岁为97.75%、16～24岁为95.75%、25～44岁为96.21%、45～59为97.52%(P<0.05);GMT最高为45～59岁(1∶3 169),最低为3～4岁(1∶1 964)和5～7岁(1∶1 589)。有麻疹疫苗接种史者抗体阳性率为96.52%;接种剂次不详者抗体阳性率为96.59%,GMT为1∶2 654(P<0.05)。[结论]太原市健康人群麻疹抗体水平较高,但各县区又有差异。
[Objective] To understand the level of measles antibody in healthy population in Taiyuan, to prepare preventive measures in a targeted manner and to prepare for the elimination of measles in 2012 in the city. [Methods] From April to May 2007, some healthy people in 6 age groups from 3 to 59 years old in Taiyuan were sampled for measles serum antibody test. [Results] The positive rate of 2 558 persons with 2 648 measles serum antibodies was 96.56%. The geometric mean titer (GMT) was 1: 250. The antibody positive rate was 96.12% in males and 96.98% in females (P> 0.05). Antibody GMT was 1: 2 034 in males and 1: 2 473 in females (P <0.05). The antibody positive rate was 95.74% in 3 ~ 4 years old, 96.41% in 5 ~ 7 years old, 97.75% in 8 ~ 15 years old, 95.75% in 16 ~ 24 years old, 96.21% in 25 ~ 44 years old, 97.52% (P <0.05). The highest GMT ranged from 45 to 59 years (1: 3,169), with the lowest from 3 to 4 years (1: 1,964) and 5 to 7 years (1: 1,589). The positive rate of antibody with measles vaccination was 96.52%. The antibody with the unknown level of inoculation was 96.59% with GMT of 1: 6565 (P <0.05). [Conclusion] The level of measles antibody in healthy people in Taiyuan is higher, but there are differences in counties and districts.
