目的探讨国际航行船舶传入蜚蠊风险情况及其影响因素logistic回归分析。方法从《口岸信息管理系统》内提取相关研究因素,采用单因素分析及多因素非条件logistic回归分析对影响因素进行筛选。采用SPSS13.0进行统计描述与分析。结果进行多因素logistic回归分析消除各变量间干扰因素后可见,对国际航行船舶外来蜚蠊传入存在影响的因素包括总吨位、船龄、船舶类型及卫生状况(P<0.05)。结论对国际航行船舶传入蜚蠊风险性影响因素进行筛选分析,可有效提高口岸拦截水平,提高一线船舶卫生检疫和监督水平。
Objective To investigate the risk of cockroaches introduced into international ships and their influencing factors by logistic regression analysis. Methods The relevant research factors were extracted from “Port Information Management System”, and the influencing factors were screened by univariate analysis and multivariate non-conditional logistic regression analysis. Using SPSS13.0 statistical description and analysis. Results After multivariate logistic regression analysis, it can be seen from the analysis of the interfered factors among the variables that the factors influencing the incoming cockroach in international ships include total tonnage, age, type of vessel and sanitation (P <0.05). Conclusion The screening of the influencing factors of cockroaches introduced into international ships can effectively improve the level of port interception and improve the level of sanitary quarantine and supervision of first-line ships.
