Abstract: Objective To understand the current situation of overweight and obesity among students at Jianghan University， their cognitive level， and related behaviors towards overweight and obesity，and provide a scientific basis for improving the current situation and intervention for overweight and obesity in college students. Methods A questionnaire survey was conducted on 900 students from Jianghan University using the stratified cluster sampling method. Results A total of 863 valid questionnaires were collected，and the detection rates of normal weight，overweight，and obesity were 64. 6%，19. 9%，and 15. 5%，respectively. There was a statistically significant difference in parental body shape，grade，and major among the three groups（P < 0.01）. The kappa value of the body weight evaluation of college students with different body sizes was 0. 464（P < 0. 001）. The proportion of those who did not pay attention to their body weight in the three groups was 14. 0%，15. 7% and 23. 9%，while the proportion of paying attention to their body weight was 47. 5%，50. 0%， and 38. 0%，respectively，with statistically significant differences（P < 0. 05）. The number of weekly exercises，duration of each exercise，and average daily sitting time among college students with different body types were significantly different（P < 0. 01）. There was a statistically significant difference in the frequency of breakfast and late-night snack consumption，as well as the regularity of three meal eating times among the three groups （P < 0.001）. In addition，the frequency of consuming sugary beverages，fried foods，and fast food was markedly different among the three groups （P < 0.001）. The logistic regression analysis results indicated that maternal body size，the frequency of late-night snacks，breakfast，and fried foods consumption，and the regularity of three meal eating times were the main influencing factors of overweight and obesity. Conclusion The detection rate of overweight/obesity among college students at Jianghan University is relatively high， and their cognitive level of overweight and obesity is relatively low. Diet and exercise are important factors affecting overweight/obesity among college students in Jianghan University. Health education or related courses should be carried out to improving their awareness of overweight/obesity， change their unhealthy eating habits， and promote exercise to reduce the risk of overweight/obesity among college students in Wuhan.
