Understand the dietary conditions of freshmen in a medical university, and explore the correlation between their dietary patterns and physical fitness levels. A dietary frequency survey was carried out among 2125 freshmen to evaluate their nutrient intake. Factor analysis was performed to extract common factors and determine dietary patterns. According to the "National Standards for Students" Physical health", the freshmen were tested for physical fitness, and the correlation analysis was conducted between the results of physical fitness score and dietary patterns. Four dietary patterns were identified by factor analysis, which were healthy dietary pattern (HDP), high fat and high sugar pattern (HFP/HSP), preserved food pattern and trace element pattern (TEP). Spearman rank correlation analysis showed the HDP and TEP were significantly positively correlated with the fitness test scores (r=0.064,0.062, p< 0.01), while the HFP and HSP was significantly negatively correlated (r=-0.057,p<0.01). Our results suggest that a healthy diet was associated with improved physical fitness performance, while a high intake of fatty and sweetened foods was associated with the opposite.
