Introduction : Sleep disorders were among the physical and psychological consequences frequently found in post-Covid-19.

The Aim : To study sleep patterns and predictors of poor sleep quality in post covid 19.

Methods:  A cross-sectional study was conducted in the Ibn Nafiss Pneumology Department of Abderahmen el Mami Ariana Hospital including a systematic clinical evaluation of patients after COVID-19 infection at 3 months using a questionnaire concerning sleep quality (Pittsburgh Sleep Quality Index).

 Résultat :  A total of 92 participants were enrolled. Among them, 67 (72%) were female. The mean age was 38 years. Sleep onset latency and sleep duration mean were respectively 33,42 minutes and 6,11 ± 1,33 hours. Forty-nine percent (49,4% %) of patients slept less than 7 hours. Night awakenings were reported by 45.4% of responders, and bad dreams by 51.%. Sixty-four of the participants had rated their sleep as poor quality post-Covid-19 and 12.3% of the participants had taken medication to facilitate sleep. None of the socio-demographic characteristics namely age, gender, level of study, smoking status, and presence of chronic disease were significantly associated with poor sleep quality.

 In multivariate analysis, stress and nervousness, (OR 12.1- p < 0.001), history of hospitalization for COVID-19 (OR 1.93 - p = 0.042), and the presence of a case of death by covid19 among relatives (OR 3.24 - p = 0.03) were an independent factor of poor sleep quality.

Conclusion: Our study confirms the significant sleep disturbance post-Covid-19. These results highlight the need for long-term follow-up of these patients in order to properly manage these events.
