Sleep quality and mental health in the context of COVID-19 pandemic and lockdown in Morocco

BACKGROUND: The lockdown of COVID-19 (Coronavirus Disease 2019) is associated with several stressful factors that can negatively affect peoples' sleep quality and mental health. Objectives: We conducted this study to evaluate sleep disorders and psychological impact associated with the spread of the COVID-19 and the lockdown on the Moroccan population. We also aimed to study the effects of respondents' beliefs and attitudes about sleep on sleep disorders, anxiety-related symptoms, and depressive symptoms. MATERIAL AND METHODS: We used a questionnaire enclosing respondents' sociodemographic information, five psychological and behavioral tests including Dysfunctional Beliefs and Attitudes about Sleep (DBAS-16), Athens Insomnia Scale (AIS), Epworth Sleepiness Scale (ESS), Hamilton Anxiety Rating Scale (HARS) and Beck Depression Inventory (BDI) test. RESULTS: Our results highlighted widespread false beliefs about sleep and the prevalence of sleep disorders, anxiety, and depression-related symptoms within the Moroccan population. Nearly 82.3% of respondents revealed false beliefs about sleep. Furthermore, we confirmed a strong positive correlation between knowledge and attitudes about sleep and the prevalence of sleep disorders, anxiety, and depression-related symptoms. However, we found no significant difference in the prevalence of sleep and psychological disorders, between healthcare workers and other professions workers. CONCLUSION: Our study revealed a high prevalence of sleep disorders, anxiety, and depressive symptoms in the Moroccan population during the COVID-19 lockdown period. Moreover, false beliefs on sleep understanding were prevalent and were presenting a risk factor leading to sleep disorders, anxiety, and depressive symptoms.
