Obstructive Sleep Apnea Linked With Higher Risk of COVID-19 Hospitalization, Complications
Obstructive sleep apnea was identified as an independent risk factor for severe coronavirus disease 2019 (COVID-19) resulting in hospitalization.

As a result of researchers examining at-risk populations amid the pandemic, OSA has been
Moreover, the researchers of the present study highlight that OSA is associated with several known risk factors linked with severe COVID-19: body mass index (BMI), diabetes, older age, and male gender.
“Such risk would have substantial effect as OSA is a common disease affecting at least 8% of the population, with higher prevalence in older age groups reaching to over 20% in individuals over 60 years of age,” noted the study authors.
Examining patients who participated in the
Association was assessed via multivariate logistic regression model, with comorbidities for either COVID-19 or OSA selected as covariates. The researchers also performed a meta-analysis with previous studies, analyzing the association between OSA and severe COVID-19.
In the analysis, 445 patients (37.3% male; mean age, 52.7 years) with COVID-19 were identified, 38 of whom had diagnosed OSA (8.5%; 50% male; mean age, 61.3 years).
“This reflects a similar prevalence of OSA diagnoses in COVID-19–infected [individuals] as in the normal population in FinnGen, where prevalence is 8%,” noted the researchers.
Of the patients requiring hospitalization for severe COVID-19 (n = 91; 36.3% male; mean age, 65.9 years), more than 1 in 5 had OSA (n = 19; 20.9%), which was shown to be associated with COVID-19 hospitalization independent from age, sex, BMI, and comorbidities. However, there was no significant difference in risk for contracting COVID-19 between patients with OSA and those without.
The meta-analysis also showed that among 15,835 control patients with COVID-19, the patients who had OSA and severe cases of COVID-19 (n = 1294) had more than double the risk of hospitalization (odds ratio, 2.37; 95% CI, 1.14-4.95; P = .021).
“We believe that our finding may help in identifying high-risk individuals for severe forms of COVID-19 infection, and therefore screening for previous indications of OSA could be beneficial among individuals testing positive for the virus,” concluded the researchers.
