摘要
目的探索福建省人体感染蛔虫易感因素。方法采用改良加腾厚涂片法(Ka-to-Katz)检查蛔虫卵;采用1:1的个体匹配方法,选择200例蛔虫感染者和200例健康的对照组进行回顾性研究,应用条件Logistic回归模型分析。结果单因素Logistic回归分析筛选出职业、文化程度、家庭人均收入、便后洗手、生吃蔬菜、喝生水、赤脚下地劳动等7因素有显著意义;多因素Logistic回归分析表明,最终引入模型的便后洗手、喝生水、赤脚下地劳动等3个因素有显著意义(P<0.05)。结论影响蛔虫感染的主要危险因素是便后不洗手、喝生水、赤脚下地劳动。
Objective To determine the susceptible factors of pupolafion in Fujian Province to Ascaris. Methods The modified Kato - Katz thick smear technique was used to examine eggs of Ascaris. A population - based case - control study including 200 cases with Ascaris and 200 healthy controls was carried out by using the paired design （1：1）. A total number of 14 factors were analyzed by conditional logistic regression. Results Seven factors were associated with Ascaris infection based on the logistic regression analysis, they were occupation, education, family average income, washing hand after defecate, eating raw vegetable, drinking unboiled water, barefoot work in fields.Three factors（washing hand after defecate, drinking unboiled water and barefoot in fields） entered the last model of the multivariate logistic regression, showing significant differences （ P 〈 0.05）. Conclusion Washing hand after defecate, drinking unboiled water and working barefoot in fields are the main risk factors assoicated with Ascaris infection.
