Abstract: Taking social background factors and risk perception as the entry point, this paper empirically analyzed the persistence in preventive behavior and exercise behavior for college students.The results show that two social background factors namely risk information and search interaction as the source of risk information, had a positive effect on rick perception significantly; risk perception had a significant and positive effect on the persistence in preventive behavior; the sense of control had a significant negative and positive effect on the persistence in preventive behavior and exercise behavior respectively. The study holds that defining the preventive and controllable behavior of COVID-19 as bivariate including preventive behavior and exercise behavior to investigate, could explore the mechanism and effect of bivariate affected by different factors from social background and risk perception. It is suggested that in the course of regular prevention and control for COVID-19, it is necessary to provide more scientific and subdivided guidance and instructions on behavioral strategy.
