Association of BODE index to daily living activities and upper limb strength in chronic obstructive pulmonary disease

Abstract

Context: Chronic obstructive pulmonary disease (COPD) is a progressive disease that reduces the functional capacity and the ability to perform activities of daily living (ADL). Aims: To determine the correlation between the BODE index (B - body mass index; O - airflow obstruction; D - dyspnea; and E - exercise capacity) with ADL and grip strength in COPD patients. Settings and Design: The study was conducted at JSS Hospital, Mysore. It was a correlational study. Subjects and Methods: Sixty-six COPD subjects were recruited by convenience sampling. Forced expiratory volume, body mass index, Six-Minute Walk Test, and Medical Research Council scale were assessed. The BODE index was calculated. The total score of London Chest Activities of Daily Living (LCADL) and grip strength were compared between the patients of the four quartiles of the BODE index. The association between LCADL and grip Strength with BODE index was analyzed. Statistical Analysis: Eta coefficient, Spearman's rank correlation coefficient and the analysis of variance were used. Results: The Eta coefficients showed the strength or the measure of associations of BODE index with age, grip strength, and LCADL. Spearman's correlation coefficient shows that there is an inverse association with grip strength and LCADL, and it was statistically significant as the P Conclusions: ADL limitation and hand grip strength test have a strong association with the BODE index in patients with moderate to severe COPD.
