Rationale: Malnutrition is common among elderly patients with ACOS and contributes to reduced respiratory muscle strength, impaired functional capacity, and poor quality of life. Age-related sarcopenia combined with chronic airway inflammation increases nutritional vulnerability. Subjective Global Assessment (SGA) and Mini Nutritional Assessment (MNA) are widely used in older adults, yet their comparative performance in elderly ACOS patients has not been well studied. This prospective study aimed to compare the diagnostic performance and clinical utility of SGA and MNA in detecting malnutrition in elderly patients with ACOS.
Methods: This study included 420 elderly patients (≥60 years) with clinically stable ACOS (mean age 68.7 ± 6.9 years; 62% male). Nutritional assessment was performed using SGA (A/B/C) and MNA (well-nourished, at risk, malnourished). Functional status was evaluated using handgrip strength and 6-minute walk test (6MWT). Agreement between SGA and MNA was analysed using Cohen’s kappa.
Results: SGA classified 46% as well-nourished, 42% moderately malnourished, and 12% severely malnourished. MNA identified 40% well-nourished, 41% at risk, and 19% malnourished. Agreement between tools was moderate (κ = 0.59). Using low FFMI as reference, SGA showed sensitivity 74% and specificity 84%, while MNA showed sensitivity 82% and specificity 71%. Malnourished patients demonstrated reduced handgrip strength, and poorer 6MWT (p < 0.001).
Conclusion: Malnutrition is highly prevalent in elderly ACOS patients. MNA is more sensitive for early risk detection, whereas SGA demonstrates greater specificity and association with functional impairment. Combining both tools may improve malnutrition identification in this population.
