摘要:

目的 分析大理白族自治州(简称大理州)20~40岁女性麻疹抗体水平,为8月龄以内(简称小月龄)婴儿的麻疹免疫策略和麻疹防控提供依据。 方法 选取2016—2020年大理州20~40岁女性4 908名,检测所有对象的麻疹IgG抗体,计算麻疹抗体几何平均浓度(GMC)。收集所有调查对象所在行政地区、民族、年龄、区域(城区、农村)、含麻疹成分疫苗(MCV)免疫史、麻疹史。将麻疹IgG抗体≥250 mIU为麻疹抗体阳性,以麻疹IgG抗体≥800 mIU定义为麻疹抗体有保护性。采用多因素Logistic回归分析评估麻疹抗体阳性的影响因素。结果 4 908名女性麻疹抗体阳性率为91.4%,保护率为63.1%,麻疹抗体GMC为1 010.25 mIU/mL。各年份之间、不同行政地区之间的麻疹抗体阳性率、保护率、GMC差异均有统计学意义(P<0.05)。不同民族、MCV免疫史的女性之间麻疹抗体阳性率、保护率、GMC差异均有统计学意义(P<0.05)。不同年龄和区域的女性之间麻疹抗体阳性率、保护率差异均无统计学意义(P>0.05),不同年龄女性之间麻疹抗体GMC差异有统计学意义(P<0.05),城区和农村女性之间麻疹抗体GMC差异无统计学意义(P>0.05)。有无麻疹史的女性之间麻疹抗体阳性率、保护率、GMC差异均无统计学意义(P>0.05)。多因素Logistic回归分析结果显示,民族、MCV免疫史是麻疹抗体阳性率的影响因素[比值比(OR)值分别为0.896、1.776,95%可信区间(CI)分别为0.842~0.952、1.425~2.214]。 结论 提高大理州女性MCV接种率有助于降低小月龄婴儿麻疹的患病风险。

Abstract:

Objective To investigate measles antibody levels in females aged 20-40 in Dali Bai Autonomous Prefecture,and to formulate a measles vaccination strategy and provide scientific evidence for children under 8 months. Methods Totally,4 908 females in Dali Bai Autonomous Prefecture were enrolled from 2016 to 2020,and measles IgG antibody was determined. The geometric mean concentration(GMC) of measles antibodies was calculated. Administrative region,ethnicity,age,region(urban,rural),measles containing vaccine(MCV) immunization history and measles history were collected. When the concentration of measles IgG antibody was ≥250 mIU,it was considered positive. When measles IgG antibody reached ≥800 mIU,it was considered to provide protection against measles. Multivariate Logistic regression model was used to analyze the influence factors for measles antibody positivity. Results Through an epidemiological survey of 4 908 females from 20 to 40 years old,the measles antibody positive rate was 91.4%,the protection rate was 63.1%,and the measles antibody GMC was 1 010.25 mIU/mL. There was statistical significance in the positive rate of measles antibody,measles antibody protection rate and measles antibody GMC between different years and administrative districts(P<0.05). There was statistical significance in the positive rate of measles antibody,measles antibody protection rate and measles antibody GMC among different ethnic groups and MCV immunization history(P<0.05). There was no statistical significance in the positive rate and protection rate of measles antibody among different age groups and regions(P>0.05). The difference in measles antibody GMC for females was statistically significant among different age groups(P<0.05). There was no statistical significance in measles antibody GMC between urban and rural(P>0.05). There was no statistical significance for the positive rate of measles antibody,the protection rate of measles antibody and the GMC of measles antibody whether there was measles history(P>0.05). Multivariate Logistic regression analysis showed that ethnicity and MCV immunization history were influence factors. The odds ratios(OR) were 0.896 and 1.776,and 95% confidence intervals(CI) were 0.842-0.952 and 1.425-2.214,respectively. Conclusions Increasing the vaccination rate of Dali Bai Autonomous Prefecture's females to MCV can effectively reduce the risk of measles infection in children under 8 months.
