Eating disorders (ED) already become a global health concern for children, adolescents, even adults, including university students and high school students. The factors are affecting eating disorder behaviour from the different dietary habits, food surroundings, nutritional education, body shape (BS), body mass index (BMI), and self-esteem (SE). Therefore, this study is important to explore this relationship in Chinese university students. The purpose of this study is to evaluate the existence of eating disorders behaviour and body shape, selfesteem, body mass index's level relationship among Chinese university students. Using random stratified sampling, the survey was performed with 481 full-time on-campus undergraduate students from five Chinese universities as respondents. The study revealed that there are 49.90 percent (n=240) undergraduate students (females=37.42 percent, N=180; males=12.47 percent, N=60) with eating disorders who are 20 years old (42.9 percent, n=103). The correlation between eating disorders behaviour and BS (r= .280**), BMI (r= .202**) have a significant relationship (p< .01), which is a substantial positive association. And SE (r=-.154**) have a significant reverse relationship (p< .01), which is a substantial negative association. BS and BMI (r= .238**) have a significant relationship (p< .01), BS and SE (r= -.375**) have a significant reverse relationship (p< .01), BMI and SE (r= -.101*) also have a significant reverse relationship (p< .05). According to the findings, SE, BS, BMI have significant relationships with suffering ED. 19-21-years-old, females, the secondary school of family education was easier lead to university students suffer eating disorder behaviours. This study expands the relationship between ED behaviour and BS, SE, BMI and further study is needed and recommended.
