🛌 More than snoring: new research links obstructive sleep apnea with changes in skeletal muscle quality.
A new study from Ben-Gurion University of the Negev and Soroka University Medical Center סורוקה - מרכז רפואי אוניברסיטאי, published in Sleep and Breathing by Springer Nature, shows a significant association between obstructive sleep apnea and changes in skeletal muscle quality.
🫁 Obstructive sleep apnea affects about 30% of adults. During sleep, the upper airways repeatedly collapse, causing breathing pauses, drops in oxygen levels, and disrupted sleep. While the condition is often associated with snoring, fatigue, concentration difficulties, and cardiovascular or respiratory risks, this study points to another important dimension: its association with skeletal muscle quality, alongside earlier findings linking the condition with reduced bone density.
🩻 The research team analyzed CT scans performed for various medical reasons, allowing them to assess bone density and muscle composition without additional tests or unnecessary radiation exposure. The findings showed that people with obstructive sleep apnea had lower skeletal muscle density and a higher skeletal muscle index than those without sleep apnea. Together, this pattern may reflect changes in muscle composition and quality, rather than simply muscle mass.
The study was led by Prof. Ariel Tarasiuk, Director of the Sleep-Wake Disorders Unit at Soroka University Medical Center and a researcher in the Department of Physiology at the Faculty of Health Sciences, Ben-Gurion University of the Negev, together with Prof. Ilan Shelef, Director of the Imaging Institute at Soroka University Medical Center. The research team included Dr. Sharon Daniel from the Department of Epidemiology and Biostatistics at Ben-Gurion University of the Negev and the Pediatric Division at Soroka University Medical Center, and medical student Samuel Francis.
🦴 The findings build on an earlier study by the same research group, published in Scientific Reports, which found a link between obstructive sleep apnea and decreased bone density.
The researchers call for routine integration of bone density and muscle quality assessment into the analysis of existing CT scans, as well as dedicated follow-up and treatment pathways for patients with obstructive sleep apnea.
📰 The study was also covered by Fox News (Fox News Health), highlighting the broader public relevance of this research.
