Abstract

Purpose: This study was conducted to explore the mediating effect of nutritional status on the relationship between symptom experience and functional status of patients with Chronic Obstructive Pulmonary Disease (COPD). Methods: A total of 141 COPD patients visiting D hospital and I hospital in B city were enrolled in this study. Data were collected from January 2017 to July 2017. Outcome variables were measured by Mini Nutritional Assessment Short-Form (MNA-SF) for nutritional status, The Memorial Symptom Assessment Scale (MSAS) for symptom experience, and The Functional Performance Inventory Short Form (FPI-SF) for functional status. The data were analyzed with descriptive statistics, Pearson's correlation, and path analysis using SPSS/WIN 21.0 and AMOS 25. Results: There was a significant negative correlation between symptom experience and nutritional status (r=-.61, p<.001), a significant negative correlation between symptom experience and functional status (r=-.40, p<.001), and significant positive correlation between nutritional status and functional status (r=.47, p<.001). Symptom experience had indirect effects on functional status through nutritional status. Conclusion: For enhancing functional status in COPD patients, it is necessary to develop nursing intervention programs to enhance symptom management as well as nutritional status.
