An Evaluation of the Relationship between Clinical BODE Score with Pulmonary Capacities and Aerobic Profile in Mild to Moderate Chronic Obese Asthmatic Patients

Role of the BODE index (including BMI، FEV1، exercise capacity and dyspnea elements) has been detected for predicting in the morbidity، survival، hospitalization and development period or as a respiratory rehabilitation intermediate evaluation. However its role is not clear in chronic obese asthmatic patients with respect to fitness profile (i. e. ∆ VO2/HR، VO2/WR، VO2 peak and 6 min-walking distance). Subjects and Tewenty seven middle–aged men (33–54 rang ys) with a mild and moderate asthma، demographic value of BMI (31. 3 ± 2. 6 kg/m2) and functional capacity 2. 7±0. 43L/min were voluntarily participated. Legion level and DSI were determined by a NYHA guidelines، as well pulmonary capacities and fitness profile including (∆VO2/HR، VO2/WR، VO2 peak and 6 min-walking distance) were evaluated by a Knudson style and YMCA’S protocol respectively. The six–min walking test performed according with an ATS recommendation and BI was calculated using the Celli’s scale. Spirometric variables (ie، FVC%، FEV1%، FEV1/ FVC، PEF%، FEF25%- 75%) and fitness indexes with BI score were not significantly corrected; but baseline FFV1% value had markedly association with a (VO2/WR)، (r = 0. 39، P= 0/045). it seems that BI score as a validation scale are not suitable for the selected aerobic or respiratory indexes evaluation in asthmatic patients. Meanwhile، we need emphasize experimentally on BI elements cross-validation، and unique variables placement or a BI score modification in the large obese population spectrum with a chronic bronchial asthma disease.
