Rationale: Preoperative malnutrition in patients with hip fractures is significantly associated with unfavorable postoperative outcomes, and simple nutritional screening upon admission is essential for early nutritional intervention. This study aimed to investigate the association between the Mini Nutritional Assessment-Short Form (MNA-SF) upon admission and gait recovery after hip fracture surgery.

Methods: The subjects were consecutive patients with hip fractures due to falls who underwent surgery at our hospital between January 2022 and December 2023. The inclusion criteria were patients who were independent in walking, with or without a cane, before the fracture. All patients were assessed using the MNA-SF upon admission. The primary outcome was gait recovery, defined as the restoration of pre-fracture walking ability by discharge. Patients who achieved gait recovery were classified as the recovered group. The Mann-Whitney U test was used to examine the association between MNA-SF score and gait recovery. Logistic regression analysis was conducted to assess the impact of MNA-SF score on gait recovery, adjusting for age. P < 0.05 was considered statistically significant.

Results: The study population consisted of 189 patients with a mean hospital stay of 49.1 days. Of these, 81 (42.9%) achieved gait recovery. The mean MNA-SF score was 9.3 for the recovered group and 8.4 for the non-recovered group (P < 0.05). The mean age was 76.4 years for the recovered group and 83.7 years for the non-recovered group (P < 0.01). In the logistic regression analysis, the odds ratio was 1.19 (95% CI: 1.01-1.39) for MNA-SF score, and 0.92 (95% CI: 0.89-0.96) for age.

Conclusion: Preoperative nutritional status assessed by the MNA-SF upon admission was significantly associated with gait recovery after hip fracture surgery, independent of age.
