流行性出血热发病危险因素病例对照研究

目的 探讨流行性出血热（ｅｐｉｄｅｍｉｃ ｈｅｍｏｒｒｈａｇｉｃ ｆｅｖｅｒ，ＥＨＦ）发病的保护因素。方法 采用１：１配对病例对照研究调查和分析有关的暴露因素。结果 调查了１８５例病例和对照，在单因素Ｘ＾２和多因素ｌｏｇｉｓｔｉｃ回归分析中，室内鼠患、农少、外出、人均年收入和住房地面的材料均有统计学意义。在Ｐ〈０．０５显著水平下，室内鼠患、农活、外出、人均年收入和住房地面的ｌｏｇｉｓｔｉｃ回归系数

A case-control study on the risk factors of epidemic hemorrhagic fever

OBJECTIVE: To study the risk factors of epidemic hemorrhagic fever (EHF). METHODS: A 1:1 matched case-control study was conducted to analyse EHF risk factors. RESULTS: One hundred and eighty-five matched pairs were investigated. Five factors were associated with risks of the disease, including rodent activity in house, farm working, travel, annual average income of an individual and ground material of the house, when chi(2) test and logistic regression model were processed respectively. The coefficients of rodent activity in house, farm working, travel, annual average income of an individual and ground material of the house in multivariable Logistic regression model were 1.377, 1.687, 1.630, -1.216 and -0.888, respectively, when P value < 0.05 was observed. CONCLUSIONS: Factors as high average income of individuals, brick or cement used as material of the ground in the house, seemed to be protective factors of EHF, which were important to the control and prevention of EHF.
