湖北省农村居民蛔虫感染危险因素的病例对照研究

CASE-CONTROL STUDY ON THE RISK FACTORS OF ASCARID INFECTION OF FARMERS IN HUBEI PROVINCE

为了解湖北省农村居民蛔虫感染主要危险因素,采用1∶1配对病例对照研究方法,从2003年湖北省人体重要寄生虫病现状调查所得蛔虫感染者中,随机抽取200例作为病例组,按性别和年龄匹配200例健康对照,应用SAS统计软件进行条件Logistic回归分析。单因素分析发现6个因素与蛔虫感染有关;多因素分析表明,蛔虫感染与使用未经无害化处理人粪尿施肥、落地食物不洗捡食和喝不洁生水之间存在显著的相关关系,其OR值分别为2.785、2.669和0.051。加强粪便无害化处理,改进不良劳动生产方式,改善不良饮食卫生习惯,有助于减少蛔虫感染。

In order to studied the main risk factors about ascarid infection of farmers in Hubei province, the case-control study with 1：1 match was employed. Total 200 persons selected randomly from those infected with asearis found in 2003, in Hubei province, were as case group. Simple and multiple Logistic regression analysis were done with SAS software. The results of simple Logistic regression analysis suggested that 6 factors were distinctly significant （P 〈 0.05）. The results of multiple Logistic regression analysis showed that the asearid infection was remarkably related to the factors, taking use of untreated feces of human and livestock, eating food on the floor without cleaning and drinking unclean raw water in Hubei province. The OR of them was 2.785, 2.669 and 0.051 respectively. So, feces treat and clean food feeding are the effective preventive strategies of preventing aseafid infection in Hubei province.
