国际航行船舶外来蜚蠊传入风险的logistic回归分析

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(P0.05)。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。

Statistical analysis on risk factors of cockroach carried with entry-exit international ships

Objective To explore the risk factors associated with exotic cockroach carried with entry-exit international ships. Methods Extracted related factors from the information management system, the data were analyzed by univariate and multivariate logistic regression. SPSS 13.0 software was adopted to realize the data processing and statistical analysis. Results The risk factors were associated with exotic cockroach carried with entry-exit international ships The factors included gross tonnage, vessel varieties, the age of vessel and sanitary conditions （P〈O05）. Conclusion By analyzing the risk factors of cockroach carried with international navigation ships, the invasion of cockroach can be effectively prevented, first-line ship sanitation quarantine and the level of supervision can be improved at the same time.
