摘要
目的:分析住院老年患者肌少症的影响因素,构建肌少症相对风险预测模型,并对结果进行比较分析。方法:采用便利抽样法,连续入选2020年7月至2021年9月在新疆医科大学第一附属医院住院的老年患者372例,应用多因素Logistic回归、决策树CHAID算法、神经网络分析肌少症的危险因素,构建Logistic回归预测模型、决策树预测模型、神经网络预测模型,采用受试者工作特征(ROC)曲线下面积(AUC)比较3种预测模型的效果。结果:住院老年患者肌少症检出率为18.82%,其中男性检出率为23.84%,女性为14.50%。3种模型的结果均显示体质指数、步速、性别为住院老年患者发生肌少症的主要影响因素。Logistic回归预测模型的AUC为0.882(95%CI 0.836~0.928),风险预测正确率为87.8%;决策树预测模型的AUC为0.874(95%CI 0.832~0.916),风险预测正确率为86.7%;神经网络预测模型的AUC为0.890(95%CI 0.848~0.931),风险预测正确率为85.8%;3种模型的预测价值均>0.7,预测效果较好。结论:多种模型可从不同的层面挖掘肌少症的危险因素,多模型有效结合能更充分地了解不同因素之间的相互作用,构建预测模型具有较好的预测作用,可为早期筛查和干预提供参考。
Objective:The influencing factors of sarcopenia in hospitalized elderly patients were analyzed,the relative risk prediction model of sarcopenia was constructed,and the results were compared.Methods:A total of 372 elderly patients hospitalized in the First Affiliated Hospital of Xinjiang Medical University from July 2020 to September 2021 were selected by convenience sampling method.Multivariate Logistic regression,decision tree CHAID algorithm and neural network were used to analyze the risk factors of sarcopenia.Logistic regression prediction model,decision tree prediction model and neural network prediction model were constructed,the area under receiver operating characteristic(ROC)curve(AUC)was used to compare the effect of the three prediction models.Results:The incidence of sarcopenia in hospitalized elderly patients was 18.82%,23.84% in males and 14.50% in females.The results of the three models showed that body mass index,walking speed,age and gender were the main influencing factors of sarcopenia for hospitalized elderly patients.The AUC of Logistic regression prediction model was 0.882(95%CI 0.836-0.928),and the accuracy of risk prediction was 87.8%.The AUC of decision tree prediction model was 0.874(95%CI 0.832-0.916),and the accuracy of risk prediction was 86.7%.The AUC of neural network prediction model was 0.890(95%CI 0.848-0.931),and the accuracy of risk prediction was 85.8%.The prediction value of the three models is all>0.7,and the prediction effect is good.Conclusion:Multiple models can excavate the risk factors of sarcopenia from different levels,and the effective combination of multiple models can more fully understand the interaction among different factors.The models have good prediction effects,and can provide references for early screening and intervention.
