Objectives: The aim of this study was to translate the official Sarcopenia Quality of Life questionnaire into Croatian language so that it is understandable for patients to answer it, after which we obtained the answers to assess further on how sarcopenia affects their lives through 7 different domains. Materials and methods: The translated SarQoL questionnaire was given to 51 patient, all of whom were older than 65 and had a diagnosis of sarcopenia according to the European Working Group on Sarcopenia in Older People (EWGSOP). Diagnoses were verified by medical record review collected from archives of the Department of Clinical Immunology and Rheumatology, University Hospital Split. Results: After the performed testing it has been established that there is a higher level of „Locomotion“ (p<0.001) and a higher level of „Daily living activities“ (p<0.001) amongst female patients. „Leisure activities“ has moderate quality (p=0.505), while „Physical and mental health“ (p<0.001), „Body composition“ (p<0.001), and „Functionality“ (p<0.001) have a low level of development. On the other hand, among male patients, there is a high level of developed „Locomotion“ (p<0.001) and „Daily living activities“ (p<0.001). However, „Physical and mental health“ (p<0.001), „Body composition“ (p=0.003), „Functionality“ (p<0.001) and „Leisure activities“ (p=0.031) are on a low level of development. Male patients were showed statistically more common with „Fear that you might not be able to“ , while female patients most commonly showed to have „Fear of feeling tired after these activities“ (p<0.001). Conclusions: The SarQoL questionnaire was translated successfully, and was understood and solved by patients without difficulties. The obtained results showed us that sarcopenia indeed decreases and causes difficulties in the quality of every day life for patients that are diagnosed with sarcopenia.
