Self-Reported Disordered Eating and Weight-Control Behaviours Across BMI Categories in Romanian Young Adults: A...

Disordered eating behaviours are increasingly common among young adults, yet nutrition-focused, region-specific data from Romania and Central and Eastern Europe (CEE) remain scarce. We characterised nutritional patterns, weight-control practices, disordered-eating indicators, body image, and psychosocial factors among Romanian young adults and tested how these differed across body mass index (BMI) categories.

In a cross-sectional online survey (March-April 2026), 753 Romanian adults aged 18-30 years (93.5% female) completed a 30-item questionnaire. Self-reported anthropometric measurements were classified using WHO BMI cutoffs. Prevalences (with Wilson 95% confidence intervals [CIs]) were compared across BMI categories using the chi-square test, and multivariable logistic regression, adjusted for age and sex, estimated odds ratios (ORs).

Most participants were normal weight (59.1%); 11.6% were underweight, 29.3% were overweight or obese, and 86.3% were omnivorous. Dietary restriction (57.4%) and physical exercise (46.7%) were the leading weight-control methods; self-induced vomiting (6.4%) and medication (4.5%) were less frequent. Lifetime compulsive/emotional eating was reported by 50.1%, current stress-related eating by 49.1%, and guilt after eating by 66.1%. Lifetime night eating reached 31.9% (current, 12.9%). Body dissatisfaction (36.1% "not at all satisfied"), difficulty looking in the mirror (66.7%) and self-reported stress (82.2%) were widespread. In adjusted models, dietary restriction, emotional eating and guilt after eating rose steeply and monotonically with BMI (overweight/obesity vs. normal weight: aOR 2.34, 2.49 and 2.73, respectively; all p < 0.001), whereas current night eating and frequent self-weighing did not differ across BMI categories (p = 0.92 and p = 0.82). Dietary restriction increased from 24.1% in underweight to 55.5% in normal-weight and 74.2% in overweight/obesity participants; corresponding gradients were also observed for emotional eating and food-related guilt.

In this predominantly female, largely urban online convenience sample of Romanian young adults, self-reported behavioural risk indicators related to disordered eating were common. Restriction, emotional eating and food-related guilt increased with BMI, whereas night eating and self-weighing showed no clear BMI gradient. These findings should be interpreted cautiously and should not be generalised to Romanian young men or rural populations without confirmation in more representative samples.
