This study aims to determine the relationship between sedentary behavior, physical activity, and sleep quality in obese university students. This cross-sectional study involved 26 obese students (15 males, 11 females) at the State University of Malang who met specific inclusion criteria. Sedentary behavior was measured using the Sedentary Behavior Questionnaire (SBQ), physical activity with the International Physical Activity Questionnaire (IPAQ), and sleep quality using the Pittsburgh Sleep Quality Index (PSQI). Data were analyzed using Pearson's correlation and normality tests via SPSS 23.0. Results showed a strong negative correlation between sedentary behavior and sleep quality (r =-0.916, p < 0.01), and a significant positive correlation between physical activity and sleep quality (r = 0.379, p < 0.05). These findings suggest that increased screen time significantly decreases sleep quality, while physical activity helps improve it. The results highlight the importance of reducing sedentary behavior and promoting physical activity to enhance sleep quality among obese students. Practical implications include developing university-based health programs that target screen-time reduction and promote active lifestyles. Although promising, the study is limited by its small sample size and cross-sectional design, which limits causal inference. Future research should consider longitudinal designs and larger populations. This study aligns with existing literature that links lifestyle factors to sleep health and contributes new data within the context of Indonesian university students. © 2025, Campus EDUCA SPORTIS S.L..
