Chronic obstructive pulmonary disease (COPD) is a common lung disease during middle age which one of its complications is depression. Depression is considered one of the major causes of severe disability worldwide. One of the factors that affect the severity and incidence of this disease is a lifestyle, especially dietary pattern. On the other hand, some studies showed the relationship between dietary patterns and depression. The present study aims to investigate the dietary patterns of people with chronic obstructive pulmonary disease and its association with depression.
The present cross-sectional study was performed on 220 patients (mean ± SD age = 54.58 ± 5.08) with chronic obstructive pulmonary disease (56.6% men, 43.4% women) from Tabriz, Iran. Questionnaires of general information, food frequency, Beck depression and physical activity were completed. The dominant dietary patterns were determined by factor analysis, and their relationship with depression was discussed by regression analysis.
Three dominant dietary patterns were identified as healthy, unhealthy, and mixed dietary patterns. An inverse relationship was found between healthy and mixed dietary patterns with depression. There is no meaningful connection between unhealthy dietary patterns and depression. Depression had a significant inverse relationship with physical activity. There was no relationship between dietary patterns and Forced Expiratory Volume for 1 s (FEV1) and Forced Vital Capacity (FVC) criteria. A positive and significant relationship was observed between mixed dietary patterns with FEV1/FVC.
Inverse relationships exist between healthy dietary patterns and depression in patients with COPD, and improves the function of the lungs. Further studies are needed to show the exact relationship between diet and COPD depression.
慢性阻塞性肺疾病（COPD）是一种中年常见的肺部疾病，其并发症之一是抑郁。抑郁被认为是全球导致严重残疾的主要原因之一。影响这种疾病严重程度和发病率的因素之一是生活方式，尤其是饮食模式。另一方面，一些研究表明了饮食模式与抑郁之间的关系。本研究旨在调查慢性阻塞性肺疾病患者的饮食模式及其与抑郁的关系。
本横断面研究对来自伊朗大不里士的 220 名慢性阻塞性肺疾病患者（56.6%男性，43.4%女性，平均年龄 ± 标准差为 54.58 ± 5.08 岁）进行了研究。完成了一般信息、食物频率、贝克抑郁和身体活动问卷。通过因子分析确定主要饮食模式，并通过回归分析讨论其与抑郁的关系。
确定了三种主要的饮食模式，即健康、不健康和混合饮食模式。健康和混合饮食模式与抑郁呈负相关。不健康的饮食模式与抑郁之间没有明显的联系。抑郁与身体活动呈显著负相关。饮食模式与 1 秒用力呼气量（FEV1）和用力肺活量（FVC）标准之间没有关系。混合饮食模式与 FEV1/FVC 呈正相关。
在 COPD 患者中，健康的饮食模式与抑郁呈负相关，并且改善了肺部功能。需要进一步的研究来表明饮食与 COPD 抑郁的确切关系。
