Can Preoperative Nutritional Status be one of the Parameters Evaluating Biological Age for Elderly Patients Undergoing Spinal Surgery? A Propensity Score–matched Analysis

Key Points

The aim is to evaluate the relationship between preoperative nutritional status and biological age in elderly spinal surgery patients.
Conducted a propensity score-matched analysis
Evaluated preoperative nutritional status using GNRI
Assessed postoperative health-related quality of life (HRQOL)
Preoperative malnutrition was significantly linked to reduced postoperative HRQOL.
GNRI demonstrated potential as a nutritional marker and biological age indicator.

Abstract

Preoperative malnutrition evaluated by GNRI was independently associated with impaired postoperative HRQOL in elderly patients undergoing spinal surgery. The GNRI may serve as a nutritional marker and a surrogate for biological age.
