[目的]探讨肺结核病人密切接触者肺结核患病的相关危险因素。[方法]对攀枝花市各级结核病防治机构登记的2007年至2008年6月尚未完成治疗疗程的肺结核病人的密切接触者进行调查,对调查结果应用非条件Logistic回归分析肺结核患病的影响因素。[结果]调查肺结核病人的密切接触者1475人,确诊活动性肺结核病人14例,患病率为0.95%。密切接触者患病率,男性为1.58%,女性为0.38%(P<0.05);居住在城市的为0.33%,居住在农村的为1.39%(P<0.05)。多因素非条件Logistic回归分析结果,性别(女性)、居住地(城市)是肺结核病人密切接触者患病的保护性因素。[结论]肺结核病人密切接触者肺结核患病率很高,男性密切接触者较女性容易患肺结核,农村密切接触者较城市容易患肺结核。
[Objective] To explore the related risk factors of tuberculosis among close contacts of tuberculosis patients. [Methods] To investigate the close contacts of TB patients who have not completed the treatment course from 2007 to June 2008 registered in Panzhihua City TB prevention and treatment institutions at all levels. Non-conditional logistic regression analysis was used to analyze the influencing factors of TB prevalence in the survey results. [Results] A total of 1475 people were investigated for close contacts of tuberculosis patients and 14 cases of active tuberculosis were diagnosed. The prevalence rate was 0.95%. The prevalence of close contacts was 1.58% in males and 0.38% in females (P <0.05), 0.33% in urban areas and 1.39% in rural areas (P <0.05). Multivariate non-conditional logistic regression analysis showed that gender (female) and place of residence (city) were protective factors of close contacts of tuberculosis patients. [Conclusions] The prevalence of tuberculosis is very high in close contacts with tuberculosis patients. In close contact with men, tuberculosis is more likely to occur in women than in women. In rural areas, close contacts are more susceptible to tuberculosis than cities.
