Latent Profile Analysis of Eating Disorders and Emotional Well-being in College Students

Background: University students face a unique combination of academic pressures, transitional life stages, and potential social isolation, which can contribute to the development of unhealthy eating patterns and emotional problems. Objectives: To explore the association between quality of life, emotional problems, and eating disorders (ED) among university students, using Latent Profile Analysis (LPA) to identify distinct eating profiles. Methods: This cross-sectional exploratory study involved a total of 1,798 university students from Brazil and Canada (mean age= 21.2; women = 78.4%). The instruments used included the Addiction-like Eating Behaviour Scale (AEBS), Depression, Anxiety, and Stress Scale (DASS-21), WHOQOL-bref, Yale Food Addiction Scale 2.0 (YFAS), Difficulties in Emotion Regulation Scale (DERS), and Impulsive Behavior Scale (UPPS-P). Results: The LPA, conducted based on the AEBS raw scores due to the absence of diagnostic criteria, identified three eating behavior profiles: Profile 1 with lower scores in AEBS and YFAS, indicating a healthy eating pattern; Profile 2 with high scores, reflecting eating compulsion; and Profile 3 with intermediate characteristics. Profile 2, associated with higher levels of anxiety, depression, and stress, showed a significantly reduced quality of life. No differences were detected regarding nationality, gender, type of university, or housing. Conclusion: The results highlight the complex relationships between eating behavior, mental health, and quality of life in university students, underscoring the need for targeted interventions to improve their well-being. Thus, ED and their consequent impact on mental health and quality of life are increasingly recognized as critical issues among university students, a group uniquely vulnerable to such challenges due to transitional life stages and academic pressures.
