This study aims to evaluate the effect of individualized nutritional management on the nutritional status, pulmonary function, and overall quality of life of patients with COPD.Methods: This research is a retrospective analysis, and the patients were grouped according to the treatment methods. This study involved 100 patients with chronic obstructive pulmonary disease and were hospitalized at our hospital from March 2022 to March 2024. Among them, 43 patients with individualized nutritional management were classified as the observation group, 57 patients with regular dietary therapy management were classified as the control group. We collect clinical data on lung function, nutritional status, scores of quality of life, psychological state evaluation index, clinical efficacy, and diet satisfaction.Results: The total effective rate of the observation group was 88.37%, which was higher than that of the control group (85.96%), and the differences were statistically significant (P < 0.05). The FEV1, FVC and FVE1% of the observation group were significantly higher than those of the control group after intervention (all P < 0.05). Moreover, after the intervention, the 6-Minute Walk Test (6MWT) distance increased, and COPD Assessment Test (CAT) scores decreased significantly in both groups, with the observation group showing greater improvements (P < 0.05).Conclusion: Nutrition management has a remarkable clinical curative effect in treating COPD patients, which can improve their nutritional status and quality of life.Keywords: nutritional management, nutritional status, quality of life, chronic obstructive pulmonary disease
