幽门螺杆菌感染危险因素的对数线性模型分析

Log-linear model analysis on the risk factors of Helicobacter pylori infection

目的为探讨哲盟地区幽门螺杆菌(Hp)感染的危险因素,1990年4月-1991年3月对599例慢性胃炎和胃溃疡患者进行了观察。方法进行流行病学调查,在单因素分析的基础上进行多因素分析。结果 Hp 阳性率53.9%(323/599)。有关 Hp 感染的影响因素经逐步回归和对数线性模型分析,表明家庭成员有胃病史和接触牲畜2个因素可能是本地区Hp 感染的重要危险因素。结论本地区 Hp 感染危险因素是家庭成员有胃病史和接触牲畜。

AIMS To study the risk factors of Helicobacter pylori(Hp)infection in Zhemeng area. METHODS An observation on 599 patients with chronic gastritis and gastric ulcer was performed from April 1990 to March 1991.Epidemiology survey,and complex factors analysis after simple factor analysis were made. RESULTS The positive rate of Hp infection was 53.9%(323/599).Log-lin- ear model and stepwise regression analysis showed that the possible family gastropathy history and animal contact were two important risk fectors as- sociated with Hp infection. CONCLUSIONS A history of family gastropathy and animal contact are two risk factors of Hp infection in this area.
