Objective To analyze the influencing factors on the occurrence of anxiety and depression among secondary school students in Shanxi Province in 2023 based on the random forest algorithm and to construct a prediction model to provide a scientific basis for preventing and controlling the occurrence of negative emotions such as anxiety and depression among secondary school students. Methods In September 2023, 104 826 secondary school students in 11 cities of Shanxi Province were selected by stratified random whole-cluster sampling method for questionnaire survey, and the Generalized Anxiety Scale(GAD-7) and the Center for Streamlined Depression Scale(CES-D) were used to investigate anxiety and depression. Epidata was used for database establishment, chi-square test was used for between-group comparisons, logistic regression was used for influencing factor analysis, and Python 3.7 was used to establish a random forest prediction model and rank the importance of each variable. Results The detection rates of anxiety and depression among secondary school students in Shanxi Province in 2023 were 33.26% and 23.72%, respectively, and were higher for girls than for boys, and higher for students in general and vocational high schools than for junior high school students. The results of multifactorial regression analysis showed that female students(OR: 1.846、1.655,95%CI: 1.794-1.901、1.602-1.710), high school(OR: 2.019、1.670,95%CI: 1.956-2.083、1.612-1.731), vocational high school(OR: 1.167、1.356,95%CI: 1.085-1.254、1.254-1.466), non-conventional family(OR: 1.105、1.248,95%CI: 1.072-1.140、1.206-1.292), living in school(OR: 1.102、1.117,95%CI: 1.070-1.136、1.080-1.155), eating fried food ≥1 time/day(OR: 1.296、1.375,95%CI: 1.227-1.369、1.297-1.457), being seriously injured(OR: 1.636、1.688,95%CI: 1.524-1.755、1.569-1.816), being bullied in school(OR: 2.315、3.411,95%CI: 2.150-2.492、3.165-3.677), being scolded by parents(OR: 2.881、3.191,95%CI: 2.766-3.001、3.059-3.328), smoking(OR: 1.344、1.435
