Correlation analysis among quality of life, knowledge, beliefs, behavioral and pulmonary function outcomes in stable-stage patients with chronic obsturctive pulmonary disease

Abstract

Objective To explore the relationship between quality of life and knowledge, beliefs, behavioral, pulmonary function outcomes in stable-stage patients with chronic obsturctive pulmonary disease (COPD). Methods Using the general data questionnaire, COPD assessment test (CAT), knowledge, attitude and behavior questionnaire to investigate 93 stable-stage COPD patients in urban and rural areas, and measure the level of forced expiratory volume in one second (FEV1%). Results CAT total score was (22.56 ± 6.40) points which was in severe level; knowledge, beliefs, behavior total score was (41.94 ± 8.20) points, and FEV1% was (59.81 ± 7.64) %.The CAT was negatively correlated with knowledge, beliefs, behavior total score and two dimensions of beliefs, behavior and FEV1%, r values were -0.262, -0.288, -0.217,-0.256 respectively, P < 0.05. Conclusions The COPD patients in stable-stage have a high level of CAT. Targeted invention should be combined with the status of the knowledge, beliefs and behavior to improve the level of air flow, and quality of life of patients.
