Overview

Cross-sectional study examines sleep quality in teachers; Mediterranean diet adherence shows no significant link.

Key Points

  • Poor sleep quality was reported by 58% of teachers, with a median Pittsburgh Sleep Quality Index score of 6.0.
  • Median adherence to the Mediterranean diet was 9.0, yet no significant associations between dietary and sleep quality scores were detected.
  • Cross-sectional analysis involved 113 teachers using self-reported questionnaires for diet and sleep evaluation.
  • Findings suggest poor sleep varies by teaching level, highlighting the need for further research into stress and diet impacts.
