Association between Serum 25-Hydroxyvitamin D Levels and Sarcopenia in Patients Undergoing Chronic Haemodialysis

Sarcopenia and vitamin D deficiency are highly prevalent among patients undergoing haemodialysis. Although vitamin D deficiency, assessed using serum 25-hydroxyvitamin D (25(OH)D) levels, is known to be associated with sarcopenia in the general population, whether serum 25(OH)D levels are associated with sarcopenia in patients undergoing haemodialysis with suppressed renal activation of 25(OH)D remains unclear. This study aimed to examine the association between serum 25(OH)D levels and sarcopenia in patients undergoing haemodialysis.
