To investigate the prevalence of night eating syndrome (NES) among university students and explore its associations with depression, stress, and body mass index (BMI), thereby providing evidence for identifying high-risk populations and developing targeted interventions.
A cross-sectional study was conducted in Nanjing, recruiting 500 university students for a questionnaire survey. The Night Eating Questionnaire (NEQ), Self-Rating Depression Scale (SDS), and Perceived Stress Scale (PSS) were used to assess NES symptoms, depressive mood, and stress levels. Statistical analyses included the Mann-Whitney U test, chi-square test, correlation analysis, and logistic regression models.
A total of 531 valid questionnaires were collected. The prevalence of NES was 6.0%(n=32), while the rates of depressive symptoms and perceived stress were 42.7%(n=227) and 49.0%(n=260), respectively. Students in the NES group had significantly higher levels of depression (P<0.001) and stress (P=0.002) compared to the non-NES group, whereas no significant difference was found in BMI (P=0.130). Spearman correlation analysis showed that NEQ scores were positively correlated with SDS and PSS scores (both P<0.001), but not with BMI (P>0.05). Logistic regression analysis revealed that depression (OR=22.995, 95% CI: 5.434-97.304, P<0.001) and stress (OR=2.825, 95% CI: 1.282-6.227, P=0.010) were positively associated with NES risk, and the risk increased with the severity of depression.
Depression and stress are critical risk factors for NES among university students. Enhancing mental health may serve as an effective approach to NES prevention and intervention.
