Researchers from the USA have shown that people with respiratory disorders during sleep have a higher risk of hospitalization and death with COVID-19. An article by specialists dedicated to a new risk factor in coronavirus infection has been published in the JAMA Network Open.
Scientists from the Cleveland Clinic analyzed data on the health of more than 360 thousand patients, for 5.4 thousand of them there was data on the nature of sleep. 1935 of the latter tested positive for COVID-19. In addition, the researchers took into account the presence of concomitant diseases, such as obesity, cardiovascular diseases, and cancer.
The analysis of scientists revealed that sleep breathing disorders — in particular, apnea – are associated with a 31 percent increased risk of severe course and death from COVID-19. At the same time, the researchers note that the presence of respiratory disorders during sleep did not increase the risk of contracting a coronavirus infection. “Our study helps to better understand the relationship between sleep disorders and the risk of adverse outcomes of COVID-19. It indicates that biomarkers of inflammation can mediate this relationship,” notes one of the authors of the work, Reena Mehra.
