While cross-ethnic differences have been reported, no consistent pattern has emerged. The purpose of this study was to examine racial and ethnic differences in weight loss behaviors among female and male college students.Patients and Methods: The American College Health Association-National College Health Assessment (ACHA-NCHA) II-C survey data from the collection periods from 2015 to 2019 was used. A total of 426,425 students participated in the survey. Most participants were White (60%) and female (68.5%). Information on students’ age, body mass index (BMI), and self-rated health was also collected. Logistic regression analyses were performed to determine cross-ethnic differences in weight loss methods among female and male students.Results: Students’ weight loss behaviors were assessed and included dieting, exercising, vomiting or taking laxatives, and the use of diet pills in the past 30 days. More than half of the participants attempted to lose weight through exercise (53.5%), and 40.3% of students dieted to lose weight in the past month. Purging and the use of diet pills were endorsed by 2.9% and 2.8% of the participants, respectively. With few exceptions, male students from racial and ethnic minority backgrounds were more likely to engage in extreme weight control practices (ie, vomiting or taking laxatives, taking diet pills) than White male students, while female students from racial and ethnic minority backgrounds were less likely to use diet and exercise as weight loss methods than White female students. For all outcomes, Biracial/Multiracial and Hispanic/Latino male students were more likely to attempt weight loss than White male students. Biracial/Multiracial female students more frequently endorsed extreme weight control behaviors than White female students.Conclusion: The results of the present study add to the growing body of literature on the relationship between race and ethnicity and weight loss behaviors. The findings indicate the need for tailored educational and intervention programs on college campuses.Keywords: ethnic minority, diet, exercise, diet pills, self-induced vomiting
