Psychosocial Predictors of Sleep Disturbances during COVID-19: differential contributions of demographic, psychological, pandemic-related factors to sleep health.

Aim: Since the declaration of COVID-19 as a Public Health Emergency of International Concern on January 30, 2020, the disease escalated into a global pandemic forcing governments around the world to impose measures that affected all aspects of life. Among other countries, Greece adopted social restriction, lockdowns, and quarantines to reduce transmission from person to person. Subjects and Methods: This cross-sectional study aimed to investigate the impact of those measures on sleep health in a Greek adult sample. An online questionnaire collected data during from 650 participant. Results: 60% of responders scored below the clinical cut-off on the RU-SATED, indicating they experienced poor sleep health. Better sleep health was reported with increased age and years of education. On the other hand, higher trauma-related distress, depression, anxiety and stress symptomatology were related to poorer sleep health. No gender differences were observed, and degree of compliance to pandemic restrictions did not influence sleep health. Hierarchical regression analysis indicated difficulty in securing enough/healthy food, testing positive for COVID-19, experiencing an increase in verbal arguments/conflicts at home and an increase in responsibilities were the strongest predictors of poor sleep heath. Conclusions: Results highlight the importance of maintaining good sleep health as a pillar of general physical and mental health.
