Changes in Eating Attitudes and Risk for Developing Disordered Eating Behaviors in College Students with Subthreshold Eating Disorders: A Cohort Study

Abstract

<b><i>Introduction:</i></b> The number of young adults with eating disorders or subthreshold eating disorders has increased recently. Although disordered eating behaviors persist once they appear, there have been relatively few studies on factors that might cause disordered eating behaviors. The purpose of this study was to investigate how the eating attitudes of young adults change over time and the risk factors that increase disordered eating behaviors. <b><i>Methods:</i></b> A total of 1,141 college students, 639 males and 502 females, participated. We investigated changes in eating attitudes (using EAT-26 and BITE), depressive symptoms (using BDI-II), and stress coping (using CISS, which has three subscales) between 2 time points: at college entrance and in the fourth year of college. We divided the students into three groups (clinical, subthreshold, and healthy) based on EAT-26 scores and compared their BDI-II and CISS scores. Next, we identified students who developed disordered eating behaviors, both clinical and subthreshold, during their time at college (exacerbated students) and compared depressive symptoms and stress coping styles between exacerbated students and healthy students (unchanged students). <b><i>Results:</i></b> The students in the subthreshold group (both males and females) scored significantly higher on the BDI-II and emotion-oriented coping (CISS-E) than the students in the healthy group at college entrance. Additionally, the exacerbated students (both males and females) scored significantly higher on the CISS-E in the fourth year than unchanged students. The female exacerbated students scored significantly higher on the BDI-II than female unchanged students at both time points. <b><i>Conclusions:</i></b> Our results show that depressive symptoms and nonadaptive stress coping are associated with an increased risk of disordered eating behaviors. This study suggests that early intervention may be necessary for both the clinical and subthreshold groups. The key to early intervention may be to manage not only eating behaviors but also depressive symptoms and stress coping.

The Relationship between Internet Addiction and Disordered Eating Attitudes Among Two Cohorts of Undergraduate Students in Karachi, Pakistan

“…(35) Our study showed that non-medical college students have more chance of developing disordered eating attitudes. This result is backed by an abundance of literature that reports eating disorders are prevalent among college students (36)(37) (38). A study done in France showed that a quarter (24.8%) of the college student population likely had eating disorders (39).…”

Effects of the COVID-19 Pandemic on Depressive Symptoms, Including Clinical and Subthreshold Levels, and Eating Behaviors in First-Year University Students

“…Several studies have indicated that the persistence of depressive symptoms in late adolescence is predictive of subsequent mental health problems [31][32][33]. We previously reported that depressive symptoms were correlated with the severity of disordered eating behaviors in university students [34]. Therefore, we examined the effects of the pandemic on the mental conditions of firstyear university students in Japan, including depressive symptoms, eating behaviors, and stress-coping styles, and compared the current year's results with the previous year's results.…”

Assessment of Intuitive Eating and Mindful Eating among Higher Education Students: A Systematic Review

“…Entering university can be a moment in life marked by great social pressure, with situations and challenges that increase the levels of stress, anxiety, and depressive symptoms [ 12 ], contributing to an increased risk of dysregulation of eating and worsening of eating behaviors [ 13 ] and body image perception, leaving university students more vulnerable to eating disorders [ 14 ]. In this context, ME and IE are useful approaches to promote improvements in eating and mental health by helping students to focus on their own cues of hunger and satiety, rather than following fashion trends or giving in to social pressure [ 15 , 16 ].…”
