بررسي رابطه‌ي بين خستگي و كيفيت خواب باكيفيت زندگي بهداشتي در افراد مبتلا به بيماري MS

A SURVAY ON THE FATIGUE AND SLEEP QUALITY AND ITS RELATION WITH THE QUALITY OF LIFE IN MULTIPLE SCLEROSIS

پيش زمينه و هدف: خستگي و خواب نامناسب از ويژگي هاي شايع و تهديدكننده بيماري MSمي باشد كه طبيعتاً بر كيفيت زندگي اين بيماران تأثير مي گذارد. هدف از اين مطالعه بررسي رابطه ي بين خستگي و كيفيت خواب با كيفيت زندگي در افراد مبتلا به بيماري MS مي باشد. مواد و روش ها: در مطالعه ايي مقطعي تعداد 217 بيمار مبتلا به بيماري MSكه به صورت سرپايي به مركز MS اروميه مراجعه كرده بودند، موردبررسي قرار گرفتند. از پرسشنامه MS (MSQoL 54)، كيفيت خواب پيتسبورگ (PSQI) ) و ابزار شدت خستگي (FSS) استفاده شد. يافته ها: در اين مطالعه تعداد 217 بيمار مورد تحليل قرار گرفت. رابطه آماري قوي، مثبت و معني داري بين نمرات كيفيت زندگي جسمي و رواني، كيفيت زندگي جسمي و شدت خستگي و كيفيت زندگي جسمي و كيفيت خواب وجود داشت. نمرات كيفيت زندگي ذهني و رواني با نمرات شدت خستگي و كيفيت خواب رابطه قويي داشت. سن رابطه منفي و معني داري با نمرات كيفيت زندگي جسمي و نمرات كيفيت زندگي ذهني و رواني داشت. همچنين رابطه معني داري با نمرات شدت خستگي و نمرات كيفيت زندگي داشت. بحث و نتيجه گيري: روابط قوي بين كيفيت زندگي، خستگي و كيفيت خواب مشاهده شد. اين يافته ها از غربالگري و پايش روتين شدت خستگي و كيفيت خواب و تأثير آن ها بر كيفيت زندگي در افراد مبتلا به بيماري MS حمايت مي كند.

Received: 6 Nov, 2015 Accepted: 15 Jan, 2016 Abstract Background Aims: MSassociated fatigue (MSF) and poor sleep are common and treatable features of MS, which affect QOL. The objective of this study was to assess the association between fatigue, sleep quality, and quality of life in people with MS. Materials Methods: Crosssectional data were collected from 217 MS patients, who were referred to the outpatient MS center of Urmia, Iran, in 2013. Healthrelated quality of life (MS Quality of Life54), fatigue (Fatigue Severity Scale, FSS), and sleep quality (Pittsburgh Sleep Quality Inventory, PSQI) were assessed. Results: We included 217 patients in the analysis. The mean plusmn SD age of patients was 32.6 plusmn 9.6 years, and 79% were female. One hundred fiftytwo (70.1%) of the patients were classified as poor sleepers based on PSQI scores. One hundred twentytwo patients (56.4%) presented significant fatigue based on FSS results. The mean physical (PCS) and mental (MCS) health composite scores of the MSQOL54 were 40.12 (SE 1.27) and 43.81 (SE 1.61), respectively. There was a strong statistically significant positive correlation between PCS scores and MCS, FSS, and PSQI scores. MCS scores were strongly correlated with FSS and PQSI scores. Age exhibited significant negative correlations with PCS and MCS scores, and it was significantly correlated with FSS and PSQI scores. Conclusions: We observed strong correlations between QOL, fatigue, and sleep quality in a large communitybased sle of individuals with MS. These findings support routinely screening and monitoring fatigue severity and sleep quality and their effects on QOL.
