INTERACTION BETWEEN PHYSICAL PERFORMANCE AND HEALTH METRICS IN PATIENTS WITH OBSTRUCTIVE SLEEP APNEA SYNDROME

Purpose: The study aimed to investigate the potential correlation between physical performance and health metrics in patients with obstructive sleep apnea syndrome (OSA), while also comparing variations in health metrics (such as obesity, hypoxia, quality of life, etc.) and physical performance across different severities of OSA. Material and Methods: Eighty-four participants undergoing polysomnography with the suspected presence of OSAS were included. Participants completed the Epworth Sleepiness Scale (ESS), 36-Item Short Form (SF-36), Hospital Anxiety-Depression Scale (HADS) questionnaires. Physical performance was assessed using the 30-Second Sit-to-Stand Test (30CST). Participants were categorized into two groups to compare health metrics based on the severity of OSA. Results: Body mass index, neck circumference, ESS scores, hypoxia levels, emotional well-being, and energy levels of SF-36, differed statistically according to the severity of OSA. While there was no correlation between 30CST scores and social functioning (r=.125, p=.290), all other SF-36 subheadings and 30CST were significantly correlated (p<.05). 30CST variance is predicted significantly by SF-36 (p<.001), HADS (p<.001), ESS (p<.001), obesity (p=.001), and hypoxia (p=.011). Conclusion: These results indicate that the physical performance of patients with OSA is correlated with health metrics, including quality of life, daytime sleepiness, anxiety-depression, hypoxia, and obesity, irrespective of the severity of apnea-hypopnea.
