Results: The results showed that morning type 1.1%, middle type 91.2% and evening type 7.7% of sleep circadian rhythm in normal-weight group and middle type 92.6% and evening type 7.4% of sleep circadian rhythm in obese group. There were statistically significant results on sleep quality with covariance sex and stress, sleep duration, habitual sleep efficiency and sleep disturbance between normal-weight and obese group. There were statistically significant results on sleep quality, sleep duration, habitual sleep efficiency and sleep disturbance in middle type of sleep circadian rhythm between normal-weight and obese group.
