Eating Habits, Body Weight Perception, and Psycho-Emotional Factors Among Romanian University Students: A...

Dietary habits adopted during young adulthood play a critical role in physical, emotional, and cognitive health. University students represent a particularly vulnerable group due to academic stress, lifestyle transitions, and increased autonomy, factors that may influence eating behaviors, body weight perception, and psychological well-being. This study aims to examine dietary habits among students and their associations with self-perceived body weight, lifestyle characteristics, and psychological factors within a biopsychosocial framework.

A cross-sectional observational study was conducted using a structured, self-administered online questionnaire distributed to university students aged 18-30 years in Romania. The questionnaire assessed dietary habits, nutritional knowledge, lifestyle behaviors, and psychological variables, including perceived stress and body weight perception. Body mass index was calculated based on self-reported anthropometric data.

The findings indicated substantial variability in dietary behaviors, with a high prevalence of irregular meal patterns, frequent snacking, and engagement in weight-control practices. Irregular meal patterns were reported by approximately 62% of participants, while 47% had engaged in at least one weight-loss diet. Discrepancies between self-reported BMI and perceived body weight were observed in roughly 38% of cases, and 83% of respondents reported at least one psychological symptom (stress, anxiety, or low mood) related to eating behaviors. A positive correlation was observed between sleep duration and perceived rest quality (r = 0.364, p < 0.001). High frequencies of caffeinated beverage consumption were also observed. Additionally, 204 participants reported no alcohol consumption, while the variety of alcoholic beverages consumed was strongly correlated with alcohol intake frequency (r = 0.734, p < 0.001).

Dietary habits among university students are closely interconnected with body weight perception, lifestyle behaviors, and psychological well-being. These findings emphasize the need for integrative health promotion strategies that address nutrition, emotional regulation, and lifestyle balance to support mental and cognitive health during young adulthood.
