The mini nutritional assessment-short form (MNA-SF) is maximal inspiratory pressure (MIP) in patients with chronic obstructive pulmonary disease.

Abstract

Introduction: Inspiratory muscle strength in patients with chronic obstructive pulmonary disease (COPD) has been reported to be related to nutritional status. Nutritional status should be evaluated from multiple perspectives. We assessed nutritional status with the clinically used mini nutritional assessment-short form (MNASF) and investigated its relation to MIP in COPD patients. Subject: This study included 86 participants (mean age 75 ± 9 years, 84% male) Methods: MIP assessed inspiratory muscle strength with a spirometer attached respiratory muscle strength meter. MNA-SF assessed nutritional status. Multiple regression analysis was performed with MIP as the dependent variable and MNA-SF, mMRC, effort lung capacity, % Forced Expiratory Volume in one second, age, and sex as independent variables. Result: A relationship was found between MIP and MNA-SF [standardized coefficient β: 0．25, p=0．002 ]. Conclusion: MIP in COPD patients was found to be associated with MNA-SF.
