目的了解茫崖县人群麻疹抗体水平,为消除麻疹提供科学依据。方法随机选定2个乡(镇),在每个乡(镇)各抽取0~岁、1~岁、3~岁、5~岁、7~14岁儿童各15名,每个乡(镇)75名,共计150名,采用酶联免疫吸附试验(ELISA)定量检测血清麻疹IgG抗体。结果人群麻疹IgG抗体总阳性率为91.33%(137/150),其中男性90.24%(74/82)、女性92.65%(63/68),男女差异无统计学意义(χ2=0.27,P=0.603);几何平均浓度(Geometric Mean Concentration,GMC)1 002.94;95%可信区间(729.53,1 378.80)。结论 2011年茫崖县14岁以下儿童麻疹抗体总阳性率低于95%,应开展强化免疫,提高儿童麻疹疫苗接种率。
Objective To understand the level of measles antibody in the population of Mangya County and provide a scientific basis for the elimination of measles. Methods Two townships (towns) were selected at random, and children aged 0 ~ 1, 1 ~ 3, children 5 ~ and children 7 ~ 14 were selected from each township ) 75, a total of 150, the use of enzyme-linked immunosorbent assay (ELISA) quantitative detection of serum measles IgG antibody. Results The total positive rate of measles IgG antibody was 91.33% (137/150) in the population, including 90.24% (74/82) in males and 92.65% (63/68) in females, there was no significant difference between male and female (χ2 = 0.27, P = 0.603 ); Geometric Mean Concentration (GMC) 1 002.94; 95% confidence interval (729.53,1 378.80). Conclusion The total positive rate of measles antibody in children under 14 in Mangya County was less than 95% in 2011. Intensive immunization should be carried out to increase measles vaccination rate in children.
