Introduction: sarcopenia and cachexia are syndromes that result in a reduction of skeletal muscle mass, being associated with the aging process and many chronic diseases. Objective: to assess the frequency of sarcopenia as well as of cachexia and their associated factors in patients in dialysis treatment. Methodology: a cross-sectional study conducted in two dialysis treatment centers in Recife between March and September 2016. The diagnosis of sarcopenia was made according to the criteria issued by the Sarcopenia European Consensus, while that of cachexia was made in consonance with the Society for Cachexia and Wasting Disorders (SCWD). The association variables were demographic (age and sex), laboratory (C-reactive protein, serum albumin, hemoglobin, parathyroid hormone, serum creatinine), and anthropometric indicators (body mass index BMI, arm circumference AC, midarm muscular circumference MMC, triceps skinfold thickness TST). Results: the study involved 66 patients, 43.9 % men, 56.1 % women, with a mean age of 53.15 ± 15.24 years; 43.9 % were elderly subjects. Sarcopenia occurred in 59.1 % of patients; of these, 15.2 % presented with severe sarcopenia. Pre-sarcopenia was found in 4.5 %. With regard to cachexia, 15.2 % were diagnosed with this syndrome. The variables associated with sarcopenia were reduced serum albumin (p = 0.013) and cachexia (p = 0.039), and those associated with cachexia were female gender (p = 0.036) and BMI (p < 0.001). Conclusion: the main finding of the present study was the high frequency of sarcopenia found in patients on treatment with dialysis. In the patients studied, sarcopenia was significantly associated with a decrease in serum albumin. Reduced serum albumin is a predictor of mortality in patients on renal replacement therapy. A high frequency of sarcopenia has been observed among study patients. Thus, the tools currently available to assess muscle mass and muscle strength should be implemented as much as possible in clinical practice to enable the incorporation of appropriate preventive and therapeutic interventions.
