Summary

Obesity Hypoventilation Syndrome(OHS) is characterized by daytime hypercapnia and sleep-disordered breathing without other causes of hypoventilation in individuals with a body mass index above 30 kg/m2. It is stated that obesity is at the basis of the metabolic changes seen in individuals diagnosed with OHS. Also sedentary lifestyle habits, which are common in obese individuals, cause the risk of sarcopenia due to loss of muscle strength and mass, accumulation of adipose tissue in the body, and decreased exercise capacity. Reduced exercise capacity due to obesity has been shown in the literature to strongly interact with mortality risk. As a result of obesity and all this negative picture, impaired emotional state and decreased quality of life are observed in individuals. Simultaneously, sleep parameters are also negatively affected. In particular, increased adipose tissue leads to loss of muscle mass and strength, increased risk of sarcopenia and sleep-related problems. The association of obesity and sarcopenia is referred to as 'sarcopenic obesity'. Sarcopenic obesity is defined as the coexistence of sarcopenia and obesity. The concept of sarcopenic obesity has recently taken its place in the literature. In particular, there are very few studies on its relationship with sleep parameters. However, while obesity is the basis of OHS, there are no studies on the presence and effects of sarcopenic obesity in this patient group. Based on this point, we aim to investigate the effects of sarcopenic obesity on sleep parameters, exercise capacity and quality of life in individuals with OHS.

Detailed description

Individuals with Obesity Hypoventilation Syndrome followed up in Istanbul University Faculty of Medicine, Department of Chest Diseases will be included in the study. Cases will be divided into two groups according to the presence of sarcopenia. The study will be conducted in accordance with the Declaration of Helsinki and informed consent will be obtained from the patients participating in the study. Before starting the study, the purpose of the study will be explained to the participants and all information about the study will be provided. Patients who agree to participate in the study will be invited to Istanbul University Faculty of Medicine, Department of Chest Diseases on certain days. The sarcopenia diagnostic algorithm is used as a reference in the assessment of the presence of sarcopenic obesity. For the diagnosis of sarcopenic obesity, sarcopenia risk, muscle strength, muscle mass and physical performance level are assessed. Body composition, comorbid levels, sleep and sleep quality, daytime sleepiness, exercise capacity, respiratory muscle strength, peripheral muscle strength, physical activity level, emotional status, sleep-related quality of life and health-related quality of life are assessed in all individuals participating in the study.

Conditions

Interventions

Type	Name	Description
OTHER	Assessment-OHS	Demographic information of individuals diagnosed with OHS without sarcopenia risk is recorded.Bioelectrical Impedance Analysis is used to analyze body composition.The comorbidity levels of the patients were assessed with the 'Modified Charlson Comorbidity Index',sleep quality was assessed with 'Polysomnography' and 'Pittsburgh Sleep Quality Index' and daytime sleepiness was assessed with the 'Epworth Sleepiness Scale'.The assessment of exercise capacity is performed with the 'Six Minute Walking Test' and the assessment of respiratory muscle strength is performed with the 'Electronic Intraoral Pressure Measurement Device'.Patients' physical activity levels are monitored with a pedometer.Quadriceps muscle strength is measured with Hand-held dynamometer and grip strength is measured with Jamar hand dynamometer. The presence of depression is assessed with the 'Beck Depression Inventory' and quality of life with 'Nottingham Health Profile' and 'Functional Outcomes of Sleep Questionnaire'.
