Abstract

Aims: To determine the prevalence of malnutrition using the PG-SGA and to explore related factors in cancer patients at treatment initiation, emphasizing the role of skeletal muscle index (SMI).

Methods: This cross-sectional study involved 152 cancer patients beginning treatment. Nutritional assessment was performed using PG-SGA. Bioelectrical impedance analysis (BIA) was used to measure body composition, including  intracellular water (ICW), extracellular water (ECW), protein mass, fat mass, and SMI. Correlation and multivariate linear regression analysis were performed on factors related to PG-SGA scores.

Results: The prevalence of malnutrition by PG-SGA was 54.6% (83/152), and the prevalence of low SMI was 38.2%. The malnourished group had significantly lower ICW, ECW, protein mass and SMI than the non-malnourished group. PG-SGA score was negatively correlated with SMI (ρ = −0.236; p = 0.003). In multivariable linear regression, SMI (b = −1.078; p = 0.004), albumin (b=−0,187; p=0,043), and platelet count (b=−0,009; p=0,049) were negatively associated with PG-SGA score.

Conclusion: Among cancer patients at treatment initiation, malnutrition is common, and SMI is associated with malnutrition severity.
