稳定期慢性阻塞性肺疾病患者生命质量与其知信行水平和肺功能状况的相关性研究

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

目的 探讨稳定期慢性阻塞性肺疾病(COPD)患者生命质量与其知信行水平及肺功能状况的相关性.方法 采用一般资料调查问卷、COPD评估测试(CAT)问卷、COPD知识、态度、行为问卷对城乡93例稳定期COPD患者进行问卷调查,并测定患者第1秒用力呼气容积占预计值百分比值(FEV1％),对结果进行分析.结果 本次受调查的93例COPD患者CAT问卷总分为(22.56±6.40)分,处于重度水平,知信行总分为(41.94±8.20)分,FEV1％值为(59.81±7.64)％,CAT问卷水平与知信行总分及信念、行为2个维度和FEV1％水平呈负相关,r值分别为-0.262、-0.288、-0.217和-0.256,P＜0.05.结论 稳定期COPD患者生命质量较低,应根据患者的知识、信念与行为的状况实施针对性干预,提高患者的知信行水平,改善患者气流受限程度,以提高患者的生命质量.

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.
