摘要
目的探讨LASSO-logistic回归模型在高尿酸血症(HUA)影响因素分析中的应用。方法回顾性收集2021年在武警宁夏总队医院参加健康体检的男性军队人员健康档案,用logistic回归和LASSO-logistic回归两种模型筛选影响HUA的因素,并用赤池信息准则(AIC)和贝叶斯信息准则(BIC)评价模型拟合效果。结果男性军队人员HUA检出率为27.3%,传统logistic回归和LASSO-logistic回归两个模型的结果均显示,HUA的关键影响因素主要有年龄、丙氨酸氨基转移酶、天门冬氨酸氨基转移酶、γ-谷氨酰转肽酶、肌酐水平和脂肪肝,其中γ-谷氨酰转肽酶[传统logistic回归模型和LASSO-logistic模型OR(95%CI)分别为1.03(1.03,1.04)、1.03(1.02,1.04)]与肌酐[两个模型OR(95%CI)均为1.05(1.05,1.06))]是影响HUA最重要的两个指标;LASSO-logistic回归模型的AIC(4221.373)和BIC(4308.966)均小于传统logistic回归模型(AIC为4223.373,BIC为4317.222)。结论基于LASSO法筛选出的变量组成的LASSO-logistic回归模型拟合效果较好,是研究HUA影响因素的可靠选择。
Objective To study the application of LASSO-logistic regression model in the analysis of the influencing factors of hyperuricemia(HUA).Methods The health records of male military personnel who participated in physical examination in Ningxia Autonomous Regional Corps Hospital of Chinese People’s Armed Police Force in 2021 were collected.Two kinds of models were established by traditional logistic regression and LASSO-logistic regression to screen the factors affecting hyperuricemia,and the model fitting effect was evaluated by AIC and BIC.Results The detection rate of HUA in male military personnel was 27.3%.The results of the two models showed that the key influencing factors of hyperuricemia were age,ALT,AST,GGT,Crea and fatty liver,among which GGT[the OR values(95%CI)of traditional logistic regression and LASSO-logistic model were 1.03(1.03,1.04)and 1.03(1.02,1.04),respectively]and creatinine levels[the OR values(95%CI)of two models were 1.05(1.05,1.06)]were the two most important factors affecting hyperuricemia.The AIC(4221.373)and BIC(4308.966)of LASSO-logistic regression model were both lower than that of the traditional logistic regression model(AIC is 4223.373,and BIC is 4317.222)(4308.966).Conclusions The logistic regression model composed of variables screened by LASSO method has a better fitting effect,and it is a reliable choice to study the influencing factors of hyperuricemia.
