目的 了解新兵破伤风抗体水平,为制订新兵破伤风类毒素(Tetanus toxoid,TT)接种策略提供依据.方法 整群抽取3个单位680名17-24岁新兵、随机抽取30名TT加强免疫1年的维和官兵作为调查对象,采用酶联免疫吸附试验进行破伤风IgG抗体检测,分析破伤风抗体阳性率和抗体几何平均浓度(Geometry mean concentration,GMC).结果 新兵、维和官兵的破伤风抗体阳性率分别为74.85％(509/680)、100％(30/30) (x2=9.94,P＜0.05),抗体GMC分别为0.05IU/ml、0.21IU/ml(t=15.73,P ＜0.05).来自12省份的新兵破伤风抗体阳性率为47.62％(湖北)-100％(内蒙古)(x2=37.24,P＜0.05),抗体GMC为0.02IU/ml(湖北)-0.09IU/ml(黑龙江)(F=5.19,P＜0.01).结论 新兵破伤风抗体阳性率低;需开展入伍新兵破伤风抗体筛查,实施TT的精准加强免疫.“,”Objective To determine tetanus antibody level among recruits and to provide evidence for tetanus toxoid (TT) vaccination of recruits.Methods We selected 680 recruits aged 17-24 years from 3 units by cluster sampling,and selected at random 30 peacekeeping soldiers who had received boosterdose TT 1 year previously.We measured tetanus IgG antibody with the enzyme-linked immunosorbent assay.We analyzed tetanus antibody positivity rates and geometric mean concentrations (GMC).Results The tetanus antibody positivity rate was 74.85％ (509/680) among recruits and 100％ (30/30) among the vaccinated peacekeeping soldiers (x2 =9.94,P ＜ 0.05);the GMCs were 0.05IU/ml and 0.21IU/ ml (t =15.73,P ＜ 0.05),respectively.The positivity rates among recruits from 12 provinces ranged from 47.62％ (Hubei) to 100％ (Inner Mongolia) (x2 =37.24,P ＜ 0.05,and GMCs ranged from 0.02IU/ml (Hubei) to 0.09IU/ml (Heilongjiang) (F =5.19,P ＜ 0.01).Conclusions The tetanus antibody level was low in recruits.We should screen recruits with a low level tetanus antibody,and implement appropriate TT booster immunization.
