Eating Disorder Risk and Its Biobehavioural Correlates in Italian University Students: The UniFoodWaste Study.

TL;DR

More than one in three Italian university students screened positive for eating disorder risk, with the strongest independent associations found for clinically relevant depressive symptoms, poor/fair self-rated health, and obesity.

Key Findings

Overall, 34.6% of Italian university students screened positive for eating disorder risk using the SCOFF questionnaire.

  • 2691 students were included in the final analysis out of 2779 who accessed the survey
  • ED risk prevalence was 39.5% among women and 21.8% among men
  • ED risk was assessed using the validated 5-item SCOFF questionnaire
  • The sample consisted of Italian university students

Clinically relevant depressive symptoms showed the strongest independent association with eating disorder risk.

  • PHQ-9 score ≥ 10 was used to define clinically relevant depressive symptoms
  • Adjusted odds ratio (aOR) for ED risk was 3.37 (95% CI 2.82–4.02)
  • This was the largest effect size among all examined predictors
  • Models were stratified by sex and adjusted by age and education

Poor or fair self-rated health was independently associated with eating disorder risk.

  • aOR for poor/fair self-rated health was 2.45 (95% CI 1.93–3.11)
  • Self-rated health was included as an exposure variable in multivariable logistic regression models
  • This was the second strongest association observed after depressive symptoms

Obesity was independently associated with increased likelihood of eating disorder risk.

  • aOR for obesity was 2.48 (95% CI 1.53–4.01)
  • Overweight was also independently associated with ED risk (aOR 1.47, 95% CI 1.06–2.03)
  • BMI was included as an exposure variable in the analysis

Risky alcohol use was independently associated with eating disorder risk.

  • Alcohol use was assessed using the AUDIT-C measure
  • aOR for risky alcohol use was 1.42 (95% CI 1.15–1.75)
  • This association was independent of other covariates in the multivariable model

Smoking and use of food delivery apps and food waste apps were each independently associated with eating disorder risk.

  • These associations were found in multivariable logistic regression models stratified by sex
  • Use of digital food-related applications was included as a novel exposure variable
  • Both food delivery apps and food waste apps showed independent associations with ED risk
  • Specific adjusted odds ratios for smoking and app use are not reported in the abstract

The study examined adherence to the Mediterranean diet as a potential correlate of eating disorder risk.

  • Mediterranean diet adherence was assessed using the Medi-Lite scale
  • It was included as an exposure variable alongside other lifestyle behaviours
  • The abstract does not report a statistically significant independent association for this variable

What This Means

This research suggests that eating disorders are a major concern among Italian university students, with more than one in three students (34.6%) screening positive for eating disorder risk. Women were nearly twice as likely as men to screen positive (39.5% vs. 21.8%). The study surveyed nearly 2,700 students and looked at a wide range of factors including mental health, body weight, lifestyle habits, and use of digital food apps. The strongest risk factors identified were depression and poor self-perceived health. Students with significant depressive symptoms were over three times more likely to screen positive for eating disorder risk, and those who rated their own health as poor or fair were about two and a half times more likely. Being obese or overweight, engaging in risky alcohol use, smoking, and using food delivery or food waste apps were also independently linked to higher eating disorder risk. These associations held even after accounting for age, education, and sex. This research suggests that universities may need to implement early screening programs for eating disorders, particularly targeting students who also show signs of depression or poor mental health. The findings point to the importance of integrated approaches that address both mental health and nutrition together, rather than treating them separately. The novel finding that digital food app use is linked to eating disorder risk also highlights a potentially new area for investigation as technology increasingly shapes how young people relate to food.
