Malnutrition is often present and under diagnosed in patients with chronic liver diseases. Many of the traditional methods used to evaluate nutritional status may be altered by edema, ascites, and protein deficit caused by liver disfunction. To compare different methods to assess nutritional status; to correlate nutritional status with severity of liver dysfunction, and to determine the role of handgrip strength to nutritional assessment in patients with chronic liver disease. This prospective, cross-sectional study evaluated 305 consecutive outpatients adults with chronic liver disease. The severity of liver dysfunction was assessed by Child`s classification and Meld score. The nutritional assessment was evaluated by subjective global assessment (SGA), anthropometry, handgrip strength, Mendenhall score, and a new malnutrition score (defined by alteration in any nutritional parameter). The anormality of all parameters was considered when the adequation percentage was under 90%. Fifty-three percent of patients were male, 43% had liver cirrhosis, 80% had viral etiology, with a mean age of 54 ± 12 years. There was a significative relationship between the severity of liver dysfunction and SGA, Mendenhall score, and the new malnutrition score. The isolated assessment of anthropometry had no relationship with the severity of liver dysfunction. According to SGA, the prevalence of malnutrition was 10% for non-cirrhotic hepatic disease, 16% for compensated cirrhosis, and 94% for descompensated cirrhosis. According to Mendenhall score, the rates were 31%, 38%, and 56%, respectively. According to the new malnutrition score, the rates were 52%, 60%, and 96%, respectively. Although there had had a significant reduction in handgrip strength with the severity of malnutrition, we can t establish a cut-off value. The performance of handgrip strength adequation percentage as a criteria for diagnosing malnutrition showed 56% of false-positive and 24% of false-negative results. The prevalence of malnutrition is variable in patients with chronic liver diseases. It depends on the method used to evaluate nutritional status and the severity of liver dysfunction. Not surprisingly, the scores who combined multiple parameters of nutritional assessment showed the higher prevalence of malnutrition. There was a significant association between nutritional status and severity of liver dysfunction. If we add the measurement of handgrip strength to nutritional assessment, the prevalence rates of malnutrition will increase because of false-positive results.
