Objectives: The study aimed to explore body shape perception of female college students, perceived body shape and desired body shape, and find the correlation between body shape perception, the degree of exercise participation and eating attitudes. Methods: By means of descriptive statistics, paired-sample t test and correlation analysis, the study took statistical analysis from among 509 participants of female college freshmen and sophomores. Results: The participants’ perceived body shape was heavier than desired body shape; there was a significant difference between the two. When their perceived body shape was heavier, desired body shape was thinner, and there were more discrepancies between the two, they got a higher score on the scale of weight reduction intention and eating attitudes. But the above three had little obvious effect on the degree of exercise participation. Conclusions: The study indicated that female college students expected a thinner body shape than their perceived body shape, and the more differences between the two were made, the more weight reduction intention they had. But in comparison with doing exercise, going on a diet was more popular with the female college students.
