学生健康危险行为严重程度的累积logit模型分析

Application of Cumulative Logit Model on the Severity of Students' Health Risk Behaviors

[目的]探讨累积logit模型在学生健康危险行为严重程度和数量分析中的应用,并与列联表卡方检验法比较。[方法]应用累积logit模型,分析10235名学生健康危险行为的严重程度和数量多少,并比较男生与女生、初中生与高中/大学生之间的差异。[结果]男生的危险行为的严重度是女生的1.5倍,初中生危险行为严重度稍高于高中/大学生;男生的危险行为数量比女生多;初中生的危险行为数量较高中/大学生少。累积logit模型分析法,比列联表卡方检验法的结论更清晰、更合理、更量化。[结论]使用累积logit模型分析有序列联表数据,具有命令简单,结果更清晰,解释更合理,且能给出影响因素量化评价(OR值)等特点。

[Objective] To explore the application of cumulative logit model on the frequencies and severity of health risk behaviors （HRB） in students, and compare with Chi-square test for contingency table. [Methods] To analyze the frequencies and severity of HRB in 10 235 students and the difference between male and female, junior school and high school/college students by using cumulative logit model. [Results] The severity of HRB was 1.5-fold higher in male than that in female. The severity of HRB in junior school students was a little higher than that in high school/college students. The frequencies of HRB in male were more than that in female. The frequencies of HRB in junior school were less than that in high school/college. The results from cumulative logit model were more clear, reasonable and quantitative than those from Chi-square test. [Conclusion] The data of ordinal contingency table can be analyzed by using cumulative logit model. The syntax commands of the model are simple and the results are more reasonable and quantitative than Chi- square test. And the results can show the quantitative evaluation of influence factors （values OR）, etc.
