Materials and Methods: This study was conducted with participation of 80 patients undergoing hemodialysis for more than 6 months three times a week, aged &gt; 18 years. Their height, dry weight, waist circumference were measured. Biochemical parameters such as serum 25-hydroxyvitamin D, lipid profile, and fasting blood glucose were analyzed. Metabolic syndrome was defined using the National Cholesterol Education Program Adult Treatment Panel III criteria. Severe vitamin D deficiency, 25 (OH) vitamin D &lt; 5 ng/ml; mild vitamin D deficiency, 25 (OH) vitamin D 5-15 ng/ml; vitamin D insufficiency, 25 (OH) vitamin D 16-30 ng/ml, and vitamin D sufficiency, 25 (OH) vitamin D &gt; 30 ng/ml were categorized. Statistical analysis of the data was performed with the use of SPSS version 21.0. Results: 48.4% of hemodialysis patients were identified to have metabolic syndrome. According to the serum levels of vitamin D; 35.0% of patients had severe vitamin D deficiency, 37.4% of patients had mild vitamin D deficiency, 18.8% of patients had vitamin D insufficiency and 8.8% of patients had vitamin D sufficiency (&gt; 30 ng/ml). Vitamin D insufficiency was significantly associated with metabolic syndrome and central obesity. Conclusions: Deficiency/insufficiency is observed in serum 25-hydroxyvitamin D levels in hemodialysis patients. Vitamin D insufficiency is associated with metabolic syndrome.</dc:description><dc:publisher>IVANO-FRANKIVSK NATL MEDICAL UNIV</dc:publisher><dc:date>2021</dc:date><dc:type>Article</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/ebyu/16930</dc:identifier><dc:identifier>https://doi.org/10.21802/gmj.2021.1.3</dc:identifier><dc:identifier>2306-4285</dc:identifier><dc:language>en</dc:language><dc:relation>GALICIAN MEDICAL JOURNAL</dc:relation><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/article</dc:type><dc:identifier>https://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/16930</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
