Background:
The prevalence of malnutrition in hospitalized patients is high and is associated with increased morbidity and mortality. At present there is no method of nutritional assessment considered of choice to identify nutritional risk.
Results:
A cross-sectional study. A total of 50 patients who started total parenteral nutrition were included in the study. The prevalence of malnutrition according to the nutritional parameters were: albumin with 39 patients (78%), lymphocyte count 36 patients (72%), body mass index (BMI) 19 patients (38%), Subjective Global Assessment (SGA) 29 patients (58%). The analysis of the subjective global assessment and objective nutritional tools (anthropometric and laboratory) showed that there is moderate agreement between SGA and BMI (Kappa = 0.53), just as SGA and lymphocyte count (k = 0.44), and poor agreement between SGA and albumin (Kappa = 0.38).
Conclusions:
There is poor correlation between Subjective Global Assessment and anthropometric and biochemical values in patients with parenteral nutrition.
