The study aims to assess the association of phase angle with nutritional and functional vulnerability among colorectal cancer surgery patients.
207 adults undergoing colorectal cancer surgery were included.
Phase angle was assessed using bioelectrical impedance vector analysis at 50 kHz.
Outcomes measured included malnutrition (using GLIM criteria), handgrip strength, and SPPB scores.
Phase angle was significantly lower in patients with nutritional vulnerability (4.57 ± 0.62° vs. 5.20 ± 0.69°; p < 0.001).
Phase angle demonstrated excellent discrimination for handgrip strength and acceptable for SPPB, but no discrimination for postoperative complications.
Phase angle ≤ 4.7° was linked with GLIM-defined malnutrition and low handgrip strength, but not with postoperative complications.
