Sleep quality and anxiety among Egyptian population during covid-19 pandemic.

Objectives: COVID-19 pandemic imposed a relevant number of stressful factors potentially impacting either daytime function or sleep quality. This study aimed to assess the sleep quality and anxiety among the general population living in Egypt. Material and Methods: A cross-sectional survey was conducted among 1,000 individuals who have been recruited via a convenience sample. A predesigned questionnaire was distributed online to collect data on sleep quality using the validated Arabic version of the Pittsburgh sleep quality index, anxiety disorders by the generalized anxiety disorder (GAD-7) scale, demographic characteristics, and clinical history. Results: Among the study participants (33.8% males, 46.2% healthcare workers, 25% had chronic diseases, 30.1% were physically active during lockdown, and 70.3% reported work termination due to COVID-19 infection, 68.4% complained of bad sleep and 70.3% showed clinically significant levels of anxiety). In multiple logistic regression analysis, bad sleep quality was significantly associated with moderate anxiety (OR: 1.88; [95% CI: 1.37-2.60]), severe anxiety (OR: 3.15; [95% CI: 2.18-4.55]), being physically active (OR: 0.53; [95% CI: 0.39-0.71]), received higher education as being postgraduate (OR: 0.56; [95% CI: 0.35-0.92]), or living with family (OR: 0.74; [95% CI :0.56-0.98]).The GAD-7 scale added 8% discrimination power for prediction of bad sleep quality compared to the model based on demographic and clinical data [with GAD: AUC=0.70, p<0.001; without GAD: AUC=0.62, p<0.001]. Conclusion: COVID-19 had a significant impact on sleep quality and anxiety among Egyptians. Since both the conditions may overlap and potentiate each other leading to chronic dysfunctional outcomes, an accurate assessment and clinical approach may favor a better prognosis.

COVID-19 and dental sleep medicine: risks, precautions and patient guidance.

COVID-19 is the offcial name for the disease caused by SARS-CoV-2, which has become a pandemic, infecting more than 5 million people worldwide. Transmission occurs by inhaling droplets generated when an infected person coughs, sneezes or exhales, or by touching contaminated surfaces and then rubbing their hands over their eyes, nose or mouth. Some infected people become seriously ill, while others have no symptoms, but even though they are asymptomatic, they can still transmit the virus. As vaccines and effective medications do not yet exist, the only way to handle the devastating consequences of the pandemic is prevention. Quality of sleep is essential for the immune system to be prepared to receive, fight and restore itself after a viral infection. Therefore, patients with obstructive sleep apnea (OSA) should continue treatment, and only suspend or change the therapeutic modality under the guidance of a sleep physician. In the era of COVID-19, due to the high probability of contamination promoted by CPAP, the mandibular repositioning device has been considered as the first choice for patients with OSA. However, as the dental approach is at high risk of contamination, due to the proximity of the dental surgeon to the patient, it is essential that the professional who works in this field knows the risks to which they are exposed. Precautions must be adopted and patients should be guided in order to control and use of their intraoral devices.

Escalation of sleep disturbances amid the COVID-19 pandemic: a cross-sectional international study.

STUDY OBJECTIVES: The stress imposed by the COVID-19 pandemic and ensuing social isolation could adversely affect sleep. As sleep problems may persist and hurt health, it is important to identify which populations have experienced changes in sleeping patterns during the pandemic and their extent. METHODS: In Study 1, 3,062 responders from 49 countries accessed the survey website voluntarily between March 26 and April 26, 2020, and 2,562 (84%; age: 45.2 ± 14.5, 68% women) completed the study. In Study 2, 1,022 adult US responders were recruited for pay through Mechanical Turk, and 971 (95%; age 40.4 ± 13.6, 52% women) completed the study. The survey tool included demographics and items adapted from validated sleep questionnaires on sleep duration, quality and timing, and sleeping pills consumption. RESULTS: In Study 1, 58% of the responders were unsatisfied with their sleep. Forty percent of the responders reported a decreased sleep quality vs before COVID-19 crisis. Self-reported sleeping pill consumption increased by 20% (P < .001). Multivariable analysis indicated that female sex, being in quarantine, and 31- to 45-years age group, reduced physical activity and adverse impact on livelihood were independently associated with more severe worsening of sleep quality during the pandemic. The majority of findings were reproduced in the independent cohort of Study 2. CONCLUSIONS: Changes imposed due to the pandemic have led to a surge in individuals reporting sleep problems across the globe. The findings raise the need to screen for worsening sleep patterns and use of sleeping aids, especially in more susceptible populations, namely, women and people with insecure livelihoods subjected to social isolation.
