Résumé
Background
Dietary quality is important for preventing and managing chronic diseases in older adults; however, its association with respiratory health remains insufficiently understood. This cross-sectional study examined the association between dietary quality and lung function among older adults in South Korea.
Methods
This cross-sectional study included 1021 adults aged ≥65 years from the 2024 Korea National Health and Nutrition Examination Survey. Dietary quality was measured using the Korean Healthy Eating Index (KHEI; range, 0–100). The forced expiratory volume in 1s (FEV1), forced vital capacity (FVC), FEV1/FVC ratio, forced mid-expiratory flow between 25% and 75% of FVC (FEF25–75%), and peak expiratory flow (PEF) were measured using spirometry. Linear regression models were used with beta coefficients and 95% confidence intervals (CIs).
