Abstract 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.
