Abstract: Objective To study the dietary patterns of college students in Suzhou City and analyze their influencing factors,so as to provide evidence for improving the dietary quality of college students. Methods From September to December,2022,a random cluster sampling method was used to select freshmen to juniors from a university in Suzhou City. The food frequency questionnaire was used to investigate the dietary situation of students,and the data were analyzed. Results There were five dietary patterns among the 511 students,namely "healthy" pattern,calcium pattern,"unhealthy" pattern,meat pattern and grain pattern. The differences of dietary patterns among college students of different gender,grade,family economic status,physical activity intensity and sleep time were statistically significant（all P<0.05）. The male students were positively correlated with grain pattern（P<0.01,OR=2.501,95%CI：1.580-3.958）. Freshmen students were positively correlated with calcium pattern（P<0.05,OR=1.988,95%CI：1.106-3.573）,and sophomores were negatively correlated with "healthy" pattern（P<0.05,OR=0.581,95%CI：0.350-0.965）. Family economic hardship was negatively correlated with calcium pattern（P<0.05,OR=0.544,95%CI：0.300-0.986） and meat pattern（P<0.01,OR=0.386, 95%CI：0.213-0.699）.Calcium pattern was positively correlated with high level of physical activity（P<0.01,OR=2.169,95%CI：1.280-3.676）. "Unhealthy" patterns were negatively associated with high levels of physical activity（P<0.01,OR=0.534,95%CI：0.317-0.898） and sleep duration ≥8 h/day（P<0.05,OR=0.616,95%CI：0.387-0.981）. Conclusion There are five dietary patterns in the surveyed college students,and different dietary patterns are affected by gender,grade,family economic status,physical activity intensity,sleep time and other factors.
