Purpose: The decline in pulmonary function is a common problem among older adults and closely associated with reduced physical performance and loss of independence. The nutritional status may play a protective role in preserving respiratory function. The present study aimed to examine the association between nutritional status and pulmonary function in older adults and to determine whether better nutritional status is associated with improved respiratory outcomes. Methods: Fifty community-dwelling older adults aged 65 years and older participated in this study. The nutritional status was assessed using the Korean version of the Mini Nutritional Assessment (MNA), and pulmonary function was evaluated using a spirometer. The pulmonary parameters included forced vital capacity (FVC), forced expiratory volume in 1 s (FEV₁), FEV₁/FVC ratio, and peak expiratory flow (PEF). Spearman’s correlation was used to examine the relationship between MNA scores and pulmonary function. Moreover, multiple linear regression analyses were performed to assess the association between categorical nutritional status (e.g., malnourished, at risk of malnutrition, and normal nutrition) and pulmonary outcomes. Results: The MNA scores were significantly and positively correlated with FEV₁ (ρ=.34, p=.015), FEV₁/FVC ratio (ρ=.33, p =.020), and PEF (ρ=.37, p=.007). In regression analyses, participants in the risk of malnutrition and normal nutrition groups had significantly higher FEV₁ (B=.734 and .903; p=.015 and .001, respectively) and FEV₁/FVC (B=22.504 and 30.710; p=.003 and p<.001, respectively) than those in the malnourished group. Conclusion: Better nutritional status is associated with improved pulmonary function, particularly FEV₁ and FEV₁/FVC ratio, among older adults. These findings suggest that nutritional assessment and timely dietary intervention play an important role in maintaining pulmonary health and potentially mitigating respiratory decline in the aging population.
