Adherence

Lower academic performance (GPA < 4.25/5.0) is a significant predictor of poor sleep quality, with students in this group having nearly four times higher risk of poor sleep compared to high-performing peers.

If you are struggling academically, check your sleep. This study found that students with lower GPAs are much more likely to have poor sleep. While it might seem like you need to stay up to study, the data suggests a link between low performance and poor sleep. Addressing sleep hygiene might be part of the solution to improving both your rest and your grades, rather than viewing them as trade-offs.

the risk of having poor sleep quality is almost four times higher in students whose cumulative grade point average (GPA) is less than 4.25 (OR = 3.83, p = 0.01).

Why this rating

Cross-sectional design; self-reported GPA and sleep; potential for reverse causality (poor sleep -> poor grades vs poor grades -> stress -> poor sleep).
