The Relationship Between the Physical Activity Level and Fatigue Perception, Quality of Life and Psychological Status in Patients with Obstructive Sleep Apnea Syndrome

Abstract

Objective:Currently, there is a need for research that examines factors which affect physical activity (PA) participation in Obstructive Sleep Apnea syndrome (OSAS) patients. The purpose of this study was to investigate the relationship between the PA level and daytime sleepiness, fatigue perception, quality of life, and psychological status in patients with OSAS.Materials and Methods:This cross-sectional study involved 38 patients with OSAS between the ages of 30-60 years. The PA level was determined using the Turkish version of the International Physical Activity Questionnaire (IPAQ). Quality of life was evaluated by the Functional Outcomes of Sleep Questionnaire and Nottingham Health Profile (NHP). The Epworth Sleepiness Scale (ESS) was used for evaluation of the sleepiness status. The fatigue perception of the patients was evaluated by the Fatigue Impact Scale (FIS) and the Fatigue Severity Scale (FSS).Results:According to IPAQ classification, 44.7% of patients were inactive. A marked correlation was observed between IPAQ-total score with ESS score (r =-0.493, p=0.002), Hospital Anxiety and Depression Scale-Anxiety score (r=-0.338, p=0.041), NHP-social isolation score (r=-0.406, p=0.013), FIS-physical score (r=-0.404, p=0.013), and FISpsychosocial score (r=-0.411, p=0.012).Conclusion:This study showed that the total amount of PA in patients with OSAS is closely related to excessive daytime sleepiness, anxiety level, social isolation and effects of fatigue on physical and psychosocial functions.
