Sleep problems among Chinese adolescents and young adults during the coronavirus-2019 pandemic.

To assess the prevalence and sociodemographic correlates of insomnia symptoms among Chinese adolescents and young adults affected by the outbreak of coronavirus disease-2019 (COVID-19). This cross-sectional study included Chinese adolescents and young adults 12-29 years of age during part of the COVID-19 epidemic period. An online survey was used to collect demographic data, and to assess recognition of COVID-19, insomnia, depression, and anxiety symptoms using the Pittsburgh Sleep Quality Index (PSQI), the Patient Health Questionnaire (PHQ-9), and the Generalized Anxiety Disorder (GAD-7) questionnaires, respectively. The Social Support Rate Scale was used to assess social support. Among 11,835 adolescents and young adults included in the study, the prevalence of insomnia symptoms during part of the COVID-19 epidemic period was 23.2%. Binomial logistic regression analysis revealed that female sex and residing in the city were greater risk factors for insomnia symptoms. Depression or anxiety were risk factors for insomnia symptoms; however, social support, both subjective and objective, was protective factors against insomnia symptoms. Furthermore, anxiety and depression symptoms were mediators of social support and insomnia symptoms. Results of this study revealed a high prevalence of sleep problems among adolescents and young adults during the COVID-19 epidemic, especially senior high school and college students, which were negatively associated with students' projections of trends in COVID-19. The adverse impact of COVID-19 was a risk factor for insomnia symptoms; as such, the government must devote more attention to sleep disorders in this patient population while combating COVID-19.

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

The lockdown of COVID-19 (Coronavirus Disease 2019) is associated with several stressful factors that can negatively affect peoples' sleep quality and mental health. 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. 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. 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. 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.
