| Sumario: | Objective: To evaluate sarcopenia and associated factors in individuals with chronic renal failure in a peritoneal dialysis program of the Unifed Health System in the Federal District. Method: Cross-sectional analytical study, individuals both sexes, over 18 years of age, and more than three months in dialysis treatment. The variables evaluated were: dialysis time, anthropometric measurements; presence of comorbidities; serum levels of albumin, creatinine, urea, ferritin, protein and calorie intake. Initially, the SARC-F instrument was applied to screening for sarcopenia. The evaluation of muscle mass was perfomed by means of bioimpedance by spectroscopy, in addition to the measurement of handgrip strength, physical performance. Malnutrition was determined by a seven-point subjective global assessment (SGA-7p). The level of significance considered was 5%. Results: The sample was created by 52 participants, aged 53,90±14,86 years. The prevalence of sarcopenia was 15 (28,85%) individuals. This condition was predominant in males and hypertensive individuals, with a statistical difference between the presence of sarcopenia in relation to GSA-7p (p=0,043), phase angle (p=0,005) and albumin (p<0,001). Reduced album levels increased the times of sarcopenia (RR, 22,22; 95%CI 0,00-0,80; p=0,034). Conclusion: Sarcopenia is prevalente in chronic renal failure and albumin is an independente fator for this condition.
