摘　　要：目的采用logistic回归与决策树模型研究功能性消化不良患者焦虑障碍的主要影响因素,了解其心理特点,以采取针对性措施提高功能性消化不良患者的心理健康状况。方法采用一般人口学资料调查表、广泛性焦虑量表(GAD-7)、胃肠症状等级评估量表(GSRS)、多维度健康状况心理控制源量表(MHLC)、精简版—尼平消化不良指数简表(SF-NDI),对新疆某两所三甲医院的537名功能性消化不良患者进行问卷调查。采用二分类logistic回归模型和基于CHAID算法的分类决策树模型分析功能性消化不良患者焦虑障碍的影响因素,分析并比较两种模型的差异。结果Logistic回归结果显示,国家机关事业单位领导及工作人员(OR=5.13,95%CI:1.031~25.529)、自由职业、无业、待业(OR=6.3,95%CI:1.291~30.749)、情绪状态越差(OR=1.167,95%CI:1.03~1.323)、胃肠症状越严重(OR=1.065,95%CI:1.037~1.095)、健康权威人士控制(OR=1.032,95%CI:1.006~1.06)与功能性消化不良患者焦虑障碍的高风险相关(P均<0.05)。决策树模型结果显示,胃肠症状、健康权威人士控制和情绪状态是功能性消化不良患者焦虑障碍的影响因素,其中胃肠症状是最主要的影响因素。结论两种模型都具有分类预测价值,但各有优劣,二者可以相互补充,使得分析结果更具实际意义。Objective To study the main influencing factors of anxiety disorders in patients with functional dyspepsia using logistic regression and decision tree models and to understand their psychological characteristics,in order to take targeted measures to improve the mental health status of them.Methods A questionnaire survey was conducted on 537 patients with functional dyspepsia from two tertiary hospitals in Xinjiang,using a general demographic data survey,Generalized Anxiety Scale(GAD-7),Gastrointestinal Symptom Rating Scale(GSRS),Multidimensional Health Control Source Scale(MHLC),and Simplified Niping Digestive Dysfunction Index(SF-NDI).Binary logistic regression model and CHAID algorithm based classification decision tree to analyze the influencing factors of anxiety disorders in patients with functional dyspepsia.Compare the differences between the two models.Results Logistic regression results showed that the leaders and staffs of state institutions(OR=5.13,95%CI:1.031-25.529),freelances,the unemployed(OR=6.3,95%CI:1.291-30.749),the worse the emotional states(OR=1.167,95%CI:1.03-1.323),the worse the gastrointestinal symptoms(OR=1.065,95%CI:1.037-1.095),and health authority control(OR=1.032,95%CI:1.006-1.06)were associated with a higher risk of anxiety disorders in patients with functional dyspepsia(P<0.05).The results of decision tree modeling showed that gastrointestinal symptoms,health authority figure control and emotional state were the influencing factors of anxiety disorders in patients with functional dyspepsia,among which gastrointestinal symptoms were the most important influencing factors.Conclusion Both models have classification and prediction value,but each has its own advantages and disadvantages.The two can complement each other,making the analysis results more practical.
