Clinical Determinants of the Six-Minute Walk Test (6MWT) in Stable Non-Cystic Fibrosis Bronchiectasis Patients.

BACKGROUND: ) in patients with diffuse non-cystic fibrosis (CF) bronchiectasis. MATERIALS AND METHODS: In this cross-sectional study, a total of 57 clinically stable patients with diffuse non-CF bronchiectasis were enrolled. Anthropometric measurements (body mass index [BMI], mid-arm muscle circumference [MAMC], and triceps skinfold thickness [TSF]), spirometric indices (forced expiratory volume in one second [FEV1], forced vital capacity [FVC], and FEV1/FVC ratio), imaging assessment (CT scan), and bacteriological sputum studies were performed, and then, 6MWT was carried out. RESULTS: was 88.92±5.59%, 93.75±3.36%, and 94.87±2.88% in the severe, moderate, and mild bronchiectasis groups (P<0.001). A significant inverse correlation was observed between the distance walked and BMI (r=-0.434, P=0.001). CONCLUSION: at rest. The extension of bronchiectasis was the only predictor of EID during the test.
