Objective: The nutritional status of chronic obstructive pulmonary disease (COPD) patients is associated with their exercise capacity. In the present study, we have explored the relationship between nutritional risk and exercise capacity in severe male COPD patients.
Methods: A total of 58 severe COPD male patients were enrolled in this study. The patients were assigned to no nutritional risk group (n=33) and nutritional risk group (n=25) according to the Nutritional Risk Screening (NRS, 2002) criteria. Blood gas analysis, conventional pulmonary function testing, and cardiopulmonary exercise testing were performed on all the patients.
Results: Results showed that the weight and BMI of the patients in the nutritional risk group were significantly lower than in the no nutritional risk group (P <0.05). The pulmonary diffusing capacity for carbon monoxide of the no nutritional risk group was significantly higher than that of the nutritional risk group (P <0.05). Besides, the peak VO2 (peak oxygen uptake), peak O2 pulse (peak oxygen pulse), and peak load of the nutritional risk group were significantly lower than those of the no nutritional risk group (P <0.05) and there were significantly negative correlations between the NRS score and peak VO2, peak O2 pulse, or peak load (r <0, P <0.05).
Conclusion: The association between exercise capacity and nutritional risk based on NRS 2002 in severe COPD male patients is supported by these results of this study.
