目的了解石家庄市人群白喉抗体水平,探讨影响白喉抗体的因素。方法对0~,1~,5~,10~,15~,20~,25~,30~,35~,40~岁组人群进行白喉抗体检测,并采用多因素Logistic回归探讨影响因素。结果石家庄市人群白喉抗体阳性率98.53%,保护率46.22%,平均浓度1.85 IU/ml。百白破(白破)疫苗的末次接种时间和是否全程免疫是影响人群白喉抗体的重要因素,OR值分别为4.161和1.759。结论石家庄市白喉防控工作取得了良好效果,近期不会有白喉暴发流行。
Objective To understand the level of diphtheria antibodies in Shijiazhuang and to explore the factors influencing diphtheria antibodies. Methods The diphtheria antibody was detected in 0 ~, 1 ~, 5 ~, 10 ~, 15 ~, 20 ~, 25 ~, 30 ~, 35 ~ 40 years old groups and multivariate logistic regression analysis was used to explore the influencing factors. Results The positive rate of diphtheria antibody in Shijiazhuang was 98.53%, the protection rate was 46.22%, and the average concentration was 1.85 IU / ml. The time of the last immunization of Baipi broken (white broken) vaccines and whether the whole immune system is an important factor influencing the diphtheria antibodies in the population with OR values of 4.161 and 1.759 respectively. Conclusion The diphtheria prevention and control work in Shijiazhuang has achieved good results. There will be no outbreak of diphtheria in the near future.
