The relationship between dysphagia, respiratory functions and anthropometry in patients with multiple sclerosis

Abstract

BackgroundIt is known that many body systems are affected as a result of dysphagia. The aim of this study is to investigate the relationship between clinical features, respiratory functions, anthropometric measurements and dysphagia in patients with multiple sclerosis (MS). MethodSeventy-five MS patients and 50 healthy controls were included in this prospective case-control study. Disability was assessed with expanded disability status scale (EDSS), and swallowing was assessed with questionnaire for the assessment of dysphagia (solid, liquid and total) for disease. Respiratory functions were demonstrated with computerized spirometry device. Body weight, height, waist, hip, and mid-arm circumference are measured. Body mass index and body fat percentage were calculated. The relationship of all these parameters with disease activity and dysphagia was investigated. ResultsThere were 75 MS patients with a mean age of 38.40 ± 11.27 years, and 50 (66.70%) were female in the study. The all type of dysphagia scores were higher in MS patients than control group (p = 0.001). Many respiratory function test scores and only hip circumference were lower in MS patients. However, especially low forced expiratory volume-1st second (FEV1), forced vital capacity (FVC) and peak expiratory flow (PEF) values were associated with disability. In addition, dysphagia scores were higher in progressive MS patients with severe disability and high frequency attacks (p = 0.001). Increased severity of dysphagia are associated with many lower anthropometric measurements (not height-especially mid-arm circumference) and respiratory function test scores. ConclusionMS affects swallowing and respiratory systems functions. They are associated with MS disease activity. Dysphagia and its severity are associated with many anthropometric measurements and respiratory functions test scores.
