Rationale: Oral intake issues are associated with poor prognosis and lower quality of life. Kyphosis affects food intake through dysphagia or gastroesophageal reflux. Using our computed-tomography-based kyphosis index (IKCT), we assessed the effect of this condition on oral intake recovery.

Methods: The case-control study included 158 patients (≥65 years) requiring nutritional support during hospitalization. To assess oral intake recovery, they were scored on the Food Intake Level Scale (FILS). Age, sex, BMI, MNA-SF (nutritional status), comorbid pneumonia, and IKCT were collected. Follow-up of 57 patients tracked changes to activities of daily living (ADL) and IKCT. Analyses employed univariate and logistic regression.

Results: The cohort (median age = 87 years, 86:72 male:female, median BMI = 19.3) had underlying respiratory (77), neurological (34), renal/urological (27), orthopedic (19), and metabolic (19) diseases. A majority (85, 54%) had comorbid pneumonia. Most (138, 87%) required ADL assistance (Barthel Index < 40). Median FILS was 5, MNA-SF was 8, and IKCT was 20. Oral intake recovery (FILS ≥ 7) occurred in 64 patients (54.7%); they were younger (83.7 vs. 87.9), tended to be men (60% vs. 48%), and had better nutrition (MNA-SF: 8.4 vs. 6.8) (P < 0.05). Pneumonia prevalence was similar between recovery and non-recovery groups, although the former had lower IKCT (18.4 vs. 22.0, P < 0.01). Higher MNA-SF (OR = 1.240, 95% CI = 1.070–1.430) and lower IKCT (OR = 1.240, 95% CI = 1.070–1.430) predicted FILS recovery (P < 0.01). At follow-up (median 862 days), IKCT was stable in 26 patients (18.4 vs. 18.5) but increased in 31 patients who could not sit up (18.0 vs. 20.0, P < 0.01).

Conclusion: Nutritional status and kyphosis severity affect food intake recovery, highlighting the importance of preventing malnutrition, maintaining ADL, and managing kyphosis in older adults.
