This study aimed to evaluate the knowledge, attitudes, and practices (KAP) of patients with chronic obstructive pulmonary disease (COPD) concerning nutritional management.
A cross-sectional study was conducted between June and August 2024, involving COPD patients from six hospitals in Jingzhou. Demographic information and KAP scores were collected and analyzed using a self-developed questionnaire.
A total of 411 valid cases were collected, with a valid response rate of 86.16%. Of the participants, 319 (77.62%) were male, 115 (27.98%) had been diagnosed with COPD for more than 10 years, and 316 (76.89%) had received education on nutritional management. The average scores for knowledge, attitudes, and practices were 7.19±5.13 (range: 0-18), 24.81±4.43 (range: 8-40), and 19.51±5.68 (range: 7-35), respectively. Correlation analysis indicated significant positive relationships between knowledge and attitudes (r = 0.629, < 0.001), knowledge and practices (r = 0.539, < 0.001), and attitudes and practices (r = 0.501, < 0.001). Structural equation modeling revealed that knowledge directly influenced attitudes (β = 0.764, < 0.001) and practices (β = 0.521, < 0.001), while attitudes also directly impacted practices (β = 0.409, < 0.001).
Patients with COPD demonstrated inadequate knowledge, negative attitudes, and inactive practices regarding nutritional management, highlighting a significant gap in effective dietary education. To enhance clinical outcomes, healthcare providers should implement targeted educational programs that emphasize the importance of nutritional management for COPD patients.
本研究旨在评估慢性阻塞性肺疾病（COPD）患者在营养管理方面的知识、态度和实践（KAP）。
于2024年6月至8月进行了一项横断面研究，纳入了荆州市六家医院的COPD患者。使用自行编制的问卷收集并分析人口统计学信息和KAP得分。
共收集到411例有效病例，有效应答率为86.16%。参与者中，319例（77.62%）为男性，115例（27.98%）被诊断为COPD超过10年，316例（76.89%）接受过营养管理教育。知识、态度和实践的平均得分分别为7.19±5.13（范围：0 - 18）、24.81±4.43（范围：8 - 40）和19.51±5.68（范围：7 - 35）。相关性分析表明，知识与态度之间存在显著正相关（r = 0.629，< 0.001），知识与实践之间存在显著正相关（r = 0.539，< 0.001），态度与实践之间存在显著正相关（r = 0.501，< 0.001）。结构方程模型显示，知识直接影响态度（β = 0.764，< 0.001）和实践（β = 0.521，< 0.001），而态度也直接影响实践（β = 0.409，< 0.001）。
COPD患者在营养管理方面知识不足、态度消极且实践不积极，凸显了有效饮食教育方面的重大差距。为改善临床结局，医疗服务提供者应实施有针对性的教育项目，强调营养管理对COPD患者的重要性。
