【摘要】 目的 了解我市成人结核杆菌感染情况，分析原因，探讨如何更好地降低结核杆菌感染率。方法 在所辖洪泽县和涟水县各抽取1个乡镇，以20～55岁健康村民为研究对象，用5TU剂量的结核菌素纯蛋白衍化物(TB-PPD)常规皮试，72h后查验反应，对结果进行统计分析。结果 查验对象共23503例，其中反应阴性率25.83%，阳性率63.29%,强阳性率10.88%；单因素及多因素统计分析结果均证实：地区(县)、性别、年龄3个变量均有显著的统计学意义。结论 本组受试对象的结核杆菌平均感染率74.17%；男性比女性更容易受到结核杆菌感染；经济是与感染有关的一个因素；“项目县”的实施，特别是线索调查对降低结核杆菌感染率是有明显效果的。

    【Abstract】 Objective In order to realize tubercle bacillus infection status in adults of Huai’an， to find out its reason, and to probe into the way of decreasing the infection rate of tubercle bacillus.Methods The healthy peasants within 20-55 years old at 2 towns in 2 counties were tested with purified protein derivative of tubercle bacillus(TB-PPD), the outcome was observed over 72 hours after testing. Results A total of 23503 subjects tested were observed, the negative rate is 25.83%, the positive rate is 63.29%, the strong positive rate is 10.88%. Both univariate and multivariate analyses confirm that all three variables(county,sex,age) have highly significant differences statistically. Conclusion The average infection rate of the subjects is 74.17%. Men are more prone to tubercle bacillus infection than women. Income is one of factors associated with the infection. The implementation of tuberculosis control program ......
