Objective: To understand the psychological status and influencing factors of college students during the online teaching under the COVID-19 outbreak, so as to provide scientific basis for the mental health education of the population group in the future. Methods: Using the method of stratified cluster sampling and self-compiled questionnaire, the students of a vocational college in Hebei province were investigated by network questionnaire. Results: Among the 4827 college students surveyed, 1138 showed anxiety, with a detection rate of 23.6%. The detection rate of depression was 10.7% in 516 patients. The incidence of anxiety was 21.4% in boys and 24.6% in girls ($\chi$2=6.024,P=0.014); The incidence of depression was 9.4% in boys and 11.3% in girls $(\chi 2=4.248, {\mathrm {P}}=0.039)$; The results of the unconditioned Logistic regression showed that: female and senior students with poor hardware and network conditions, dissatisfaction with online teaching, difficulty in completing homework, and poor self-control were more likely to suffer from anxiety. The OR values(95% CI)were 0.646(0.590$\sim$0.706),0.899(0.853$\sim$0.946), 0.822(0.752$\sim$0.899), 1.151(1.019$\sim$1.301), 1.221(1.144$\sim$1.303), and 0.867(0.840$\sim$0.895), respectively. And female students with poor hardware and network conditions, dissatisfaction with online teaching, difficulty in completing assignments, and poor self-control were more likely to suffer from depression. The OR values(95% CI) were 0.863 (0.757$\sim$0.985), 0.841(0.739$\sim$0.956), 1.243(1.059$\sim$1.460), 1.059(1.012$\sim$1.107) and 0.904(0.864$\sim$0.946), respectively.
