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.
