摘      要：1)Background:The common factors which potentially contribute to the development of eating disorders and exercise dependence during early adulthood are still relatively *** present study aimed to examine the role of BMI,body image inflexibility,and generalized anxiety in these two behavioral problems in a sample of college students.2)Methods:In total,878 habitual exercisers(58.1%male with BMI=22.12±2.39;41.9%female with BMI=20.55±2.21)with age of 20.09±1.76 years participated in this *** main outcomes of interest are exercise dependence symptoms,eating disorders symptoms,body image inflexibility,and symptoms of generalized anxiety(as measured by Exercise Dependence Scale-Revised,Eating Disorder Examination-Questionnaire-Short Form,Body Image Acceptance and Action Questionnaire,and Generalized Anxiety Disorder-7,respectively).Pearson correlation,path analysis,and model fit information were tested.3)Results:After controlling for age,gender,and field of study,lower BMI was linked to more exercise dependence symptoms but this association was not statistically significant,while a greater BMI was significantly associated with a higher risk of developing eating disorders(β=−0.08,p0.001).Moreover,higher body image inflexibility significantly and positively contributed to severe exercise dependence(β=0.26,p0.001)as well as abnormal eating attitudes and behaviors(β=0.74,p0.001).Furthermore,generalized anxiety is a significant contributor to exercise dependence symptoms(β=0.14,p0.001)but not eating disorders symptoms.4)Conclusion:Based on our finding that body image inflexibility is a common risk factor for the development of exercise dependence and eating disorders,the prevention and treatment of these two disorders should involve the improvement of psychological *** addition,the individual with a higher BMI is more vulnerable to developing eating disorders,while those who have severer generalized anxiety symptoms should be given more attention whe
