Key Points

To investigate the relationships among physical activity, psychological symptoms (depression, anxiety, stress), sleep quality, and body composition in young adults.
Cross-sectional assessment of 572 Turkish university students (mean age 20.79±2.71 years, 50.5% female).
Assessed physical activity using the Physical Activity Scale–2 (PAS-2), psychological symptoms using the DASS-21, sleep quality using the Basic Scale for Insomnia Complaints and Sleep Quality, and body composition via bioelectrical impedance analysis (InBody 120).
Evaluated relationships using descriptive statistics, Pearson correlation analyses, and multiple regression models.
Physical activity demonstrated no statistically significant associations with psychological symptoms or sleep quality (p > .05).
Higher depression scores (β = .175) and higher stress scores (β = .246) significantly predicted poorer sleep quality.
