部队肺结核发病因素的病例对照研究

目的　研究部队人员肺结核发病的危险因素。方法　采用１∶２ 配比的病例对照研究对８６ 个病例及１５３ 个对照的相关资料进行条件ｌｏｇｉｓｔｉｃ 回归分析，计算比值比（ＯＲ） 。结果　单因素分析中，文化程度、肺结核病例接触史、卡介苗接种史及卡痕等因素的ＯＲ 值分别为２．１９ 、２ ．０３、０ ．３８和０ ．５４（Ｐ＜０ ．０５） 。多因素分析中卡痕、肺结核病例接触史和文化程度进入了最终模型，ＯＲ值分别为０ ．３６ 、１ ．９４和２ ．３３。结论　卡介苗接种对预防部队人员结核病有作用，肺结核病例接触史是一个潜在的危险因素。

Case-control studies on risk factors for pulmonary tuberculosis in servicemen of China

OBJECTIVE: To study the risk factors for pulmonary tuberculosis (PTB) in the servicemen of armed forces and lay a basis for its prevention and control. METHODS: A 1:2 matched case-control study was carried cut in the servicemen, with 86 cases and 153 controls. Data were analyzed with conditional logistic regression with EGRET software. Odds ratios (ORs) were calculated for the relevant factors. RESULTS: Single-variable analysis showed that schooling, history of exposure to PTB, history of Bacille Calmette-Guérin (BCG) vaccination and BCG vaccination scar all associated with the incidence of PTB, with ORs of 2.19, 2.03, 0.38 and 0.54, respectively, and P < 0.05. Multiple logistic regression analysis showed that BCG vaccination scar, history of exposure to PTB and schooling all entered the final regression model, with ORs of 0.36, 1.94 and 2.33, respectively. CONCLUSION: It suggested that BCG vaccination could play a role in the prevention of TB in the servicemen, and history of exposure to PTB was a potential risk factor for TB as well.
