Eating Right, Sleeping Tight? A Cross-Sectional Study on the Student-Athlete Paradox for Diet and Sleep Behaviors

Year: 2025

Type: article

Abstract: Background: Student-athletes face the dual challenge of balancing academic and athletic commitments, which may simultaneously promote healthy lifestyle habits while increasing psychosocial and physiological stressors, particularly among female student-athletes. Understanding how these competing demands affect key behavioral (e.g., dietary habits, sleep, and chronotype) and psychological (e.g., body image) factors is essential for supporting their overall well-being. Therefore, this cross-sectional study investigated body dissatisfaction, adherence to the Mediterranean diet, sleep quality, and chronotype in female student-athletes compared to sedentary peers. Methods: Twenty-eight female participants voluntarily participated in the study. Twelve volleyball student-athletes (age 21.6 ± 2.4 years) were assessed during their competitive in-season period, and sixteen non-athlete students with a high sitting time (age 24.0 ± 3.2 years) completed the Mediterranean Diet Adherence questionnaire (PREDIMED), Pittsburgh Sleep Quality Index (PSQI), Morningness–Eveningness Questionnaire (MEQ), and Body Image Dimensional Assessment (body dissatisfaction) to assess their overall well-being. Results: Student-athletes showed significantly (p < 0.05) higher adherence to the Mediterranean diet (PREDIMED: 8.5 ± 1.5 score), although experiencing poorer sleep quality (PSQI: 6.8 ± 3.0 score) compared to non-athlete students with higher sitting times (PREDIMED: 6.7 ± 1.6 score; PSQI: 4.6 ± 2.3 score). Conversely, comparative body dissatisfaction was significantly higher in non-athlete students with a high sitting time (19.4 ± 24.5%) than in student-athletes (5.6 ± 10.5%). No significant differences emerged for chronotype or overall body dissatisfaction. Conclusions: These findings highlight a paradoxical health pattern in female student-athletes who combine healthier eating habits with poorer sleep quality. The results emphasize the importance of comprehensive wellness strategies that integrate dietary habits, sleep hygiene, and psychophysiological factors to better support female student-athletes in managing dual-career demands.
