Keywords:
COPD, Six minute walk test, anxiety, depression, HADSAbstract
Purpose of study: Chronic obstructive pulmonary disease (COPD) is a severe pulmonary disease with varying impact on the patient’s general physical condition, functioning and quality of life. Anxiety and Depression are common comorbidities in COPD patients which affects exercise capacity in COPD patients. There is lack of literature of assessment of depression and anxiety in COPD patients. Therefore, the current study was undertaken.
Aim and objective: To find out the correlation between Hospital Anxiety and Depression Scale (HADS) and Six Minute Walk Test (6MWT) Performance in Chronic Obstructive Pulmonary Disease (COPD) Patients.
Methodology: All the participants were selected according to sample of convenience and given a thorough explanation of the procedure in the language they understand. Each participant signed a written consent before participating in the study in the language they could comprehend. Subjects were screened on the basis of selection criteria and a total of 100 participants were selected. Their anthropometric and demographic data was recorded. The participants were given the HADS and then asked to perform the Six-minute walk test (6MWT) and the distance was calculated.
Result: In this abnormal depression group the r= -0.3148, p= 0.0047 which shows there is negative correlation, which is strongly significant. In this abnormal anxiety group the r=-0.4115, p= 0.0001 which shows there is fairly negative correlation which is found to be significant.
Conclusion: The study thus concluded that, as anxiety and depression increases Six-minute walk test (6MWT) distance decreases.
