摘要

Background

Despite growing recognition of the complex interplay between eating patterns and health outcomes, few studies have simultaneously examined the associations between Mediterranean diet adherence, binge eating behavior, and oral health-related quality of life (OHRQoL). This study aimed to address this gap by exploring these variables in a large adult population.

Methods

A cross-sectional study was conducted among 1006 adults (aged 18–65 years) in Türkiye using an online survey. Validated instruments included the Mediterranean Diet Adherence Scale (MEDAS), Binge Eating Scale (BES), and the OHQoL-UK. Spearman correlation and multiple linear regression analyses were performed. A p-value < 0.05 was considered statistically significant.

Results

The mean age of participants was 32.52 ± 12.8 years. Based on MEDAS scores, 46.7% of participants were classified as adherent to the Mediterranean diet. Binge eating behavior was significantly and negatively correlated with MD adherence (r = − 0.112, p < 0.001) and OHRQoL (r = − 0.078, p < 0.05), and positively correlated with BMI (r = 0.235, p < 0.001). Regression analysis identified BMI (β = 0.425, p < 0.001), gender (female; β = − 0.169, p < 0.001), marital status (single; β = 0.259, p < 0.001), income status (β = − 0.061, p = 0.034), MEDAS score (β = − 0.100, p < 0.001), and OHQoL-UK score (β = − 0.069, p = 0.017) as significant predictors of binge eating behavior, collectively explaining 20.5% of the variance (R² = 0.205).

Conclusion

This study is among the first to explore these variables simultaneously and demonstrates that, beyond sociodemographic and weight-related factors, dietary and oral health indicators also independently contribute to binge eating behavior. These findings highlight the need for multidisciplinary prevention strategies integrating nutritional, psychological, and oral health dimensions.
