【摘要】 目的探索人体钩虫易感因素。方法本研究采用1∶4的个体匹配方法,选择88例钩虫感染者和352名健康对照进行回顾性调查,进行条件 Lgistic 回归模型分析。结果单因素 Logistic 回归分析筛选出使用未处理人畜粪便(X9)、饭前洗手(X10)、便后洗手(X11)、吃洗净瓜果(X12)、饮生水(X14)和赤脚下地劳动(X16)等6个相关因素有显著意义;多因素 Logistic 回归分析表明,最终引入模型的3个因素饮生水(X14)、使用未处理人畜粪便(X9)和家庭总收入(X5)有显著意义(P<0.05)。其 OR 值分别为3.3609、2.4267和0.9998。结论认为影响钩虫感染的主要危险因素是:饮生水、使用未经无害化处理的人畜粪便和家庭经济状况。更多还原

【Abstract】 Objective To determine the infection factors of hookworm.Methods A population-based case-control study including 88 cases of hookworm and 352 controls was carried out using paired design(1: 4).A total number of 14 factors were analyzed by conditional logistic regression.Results Seven factors were associated with hookworm infection based on the logistic regression analysis.There were family general in- come(X5),fertilizing fresh excreta on farmland(X9),washing hand before eating(X10),washing hand after defecate(X11),eating washup melon and fruit(12),drinking unboiled water(X14) and barefoot go to work in the fields(16).Three factors(X5,X9,X14) entered the last model of the multivariate logistic regression.There were significant differences (P<0.05).The odds ratio following 3.3609(X14)、2.4267(X9) and 0.9998(X5). Conclusions Drinking unboiled water、fertilizing fresh excreta on farmland and family general income were the main risk factors of hookworm infection.更多还原
