Scored Patient-Generated Subjective Global Assessment (PG-SGA) in Brazilian Cancer Patients and Association with Anthropometric Parameters.

INTRODUCTION

The Scored Patient-Generated Subjective Global Assessment (PG-SGA) is a multidimensional tool used to assess malnutrition and associated risk factors.

OBJECTIVE

To evaluate the nutritional status of Brazilian cancer patients hospitalized using the Scored PG-SGA and to examine the correlations with selected nutritional parameters.

METHODS

This observational study included 2.027 cancer patients aged over 18 years at a hospital of cancer, Brazil. All patients were assessed for nutritional status using the Brazilian PG-SGA and anthropometric measurements were evaluated.

RESULTS

According to the PG-SGA global assessment categories, 56.2% (1.138) cancer patients were well-nourished, 29.3% (594) were moderately malnourished, and 14.4% (292) were severely malnourished. The average body mass index (BMI) was 23.7±5.49 kg/m², and the current weight was 66.34±58.07 kg. The PG-SGA, nutritional status and clinical variable assessed by PG-SGA, were all significantly correlated with body mass index (p < 0.005) and weigh < 0.005).

CONCLUSIONS

The Brazilian PG-SGA showed a 43.7% of malnourished cancer patients. The classification of severely malnourished by PG-SGA demonstrated strong positive correlations with BMI. Anthropometric parameters correlates with PG-SGA variable, weigh with sex, nausea, diarrhea, dysgeusia, diagnostics of cancer, fever and death and BMI with sex, food intake, nausea, diarrhea , dysgeusia.
