临沂市育龄妇女破伤风抗体水平监测

MONITORING OF THE LEVEL OF TETANIC ANTIBODY IN WOMEN OF CHILDBEARING AGE IN LINYI CITY

目的 了解临沂市育龄妇女破伤风抗体水平。方法 采用间接血凝试验检测了346名在临沂市兰山区居住的育龄妇女破伤风抗体。结果 破伤风抗体阳性率44.22％,抗体阳性者破伤风抗毒素(阳性TAT)平均含量0.096U/ml。常住育龄妇女119人,破伤风抗体阳性率66.39％,阳性TAT平均含量为0.100 U/ml;暂住育龄妇女227人,破伤风抗体阳性率32.60％,阳性TAT平均含量为0.092U/ml。不同户籍的育龄妇女破伤风抗体阳性率有非常显著的差异(x^2=35.74,P<0.01),阳性TAT平均含量无显著差异(t=0.400,P>0.05)。常住育龄妇女各年龄组之间破伤风抗体阳性率、阳性TAT平均含量无显著差异。暂住育龄妇女破伤风抗体阳性率(x^2=16.23,P<0.05)、阳性TAT平均含量均随年龄的增长而下降(F=2.933,P<0.05)。结论 常住育龄妇女的破伤风保护水平较高,暂住育龄妇女的破伤风保护水平较低。

Objective To explore the level of tetanic antibody in women of childbearing age in Linyi City. Methods The level of tetanic antibody in 346 women of childbearing age in Linyi City underwent indirect blood coagulation detection. Results The positive rate of tetanic antibody was 44. 22% . The average level of tetanus an-titoxin(TAT) in the cases of positive antibody was 0. 096u/ml. The positive rate of tetanic antibody of 119 women from permanent residents was 66. 39% ,and their average level of TAT was 0.100u/ml. The positive rate of tetanic antibody of 227 women from temporary residents was 32. 60%,and their average level of TAT was 0.092% u/ml.There existed marked difference (X2=35.74,P<0.01 )in the positive rates of tetanic antibody between women from different residences,while no significant difference( t =0.400, P >0.05) in the average level of positive TAT. There existed no significant difference in positive rate of tetanic antibody from groups of different ages or in the average level of positive TAT. The positive rate of tetanic antibody (X2=16. 23, P< 0.05) and the average level of positive TAT go down with their ages (F=2.933, P<0.05). Conclusion Women of childbearing age from permanent residents have higher tetanic preventive rate than those from temporary ones.
