Poor sleep quality is significantly associated with higher levels of depression, anxiety, and stress in medical students.
If you are a medical student, recognize that poor sleep is linked to higher anxiety and depression. While some high achievers sleep poorly, this comes with a mental health cost. Prioritizing sleep quality may help manage stress levels.

Sleep quality was significantly associated with depression (p = 0.013), anxiety (p = 0.003), and stress (p = 0.004), respectively.
Why this rating
Cross-sectional design limits causal inference; sample size is small (n=95) with a low response rate (46%).
