Usefulness of the Mini Nutritional Assessment Short-Form for Evaluating Nutritional Status in Patients with Nontuberculous Mycobacterial Pulmonary Disease: a Prospective Cross-Sectional Study

Although the Mini Nutritional Assessment (MNA) is recognized as a useful tool for evaluating nutritional status in patients with various diseases, its applicability in patients with nontuberculous mycobacterial pulmonary disease (NTM-PD) remains undetermined. We designed a prospective cross-sectional study to investigate whether the MNA Short-Form (MNA-SF) score can serve as a screening tool to assess the nutritional status of patients with NTM-PD. The MNA-SF was conducted upon patient enrollment, and correlation analyses were performed to compare MNA-SF scores with other nutritional measurements and disease severity. Multivariable logistic regression analyses were conducted to evaluate the association between MNA-SF scores and NTM-PD severity. The 194 patients with NTM-PD included in the analysis had a median age of 65.0 (59.0–69.0) years; 59.3
