Abstract：
OBJECTIVE: Limited research exists on the association between dietary patterns (DP) and COPD risk or health-related outcomes. We reviewed existing literature to identify DP as a potential factor influencing COPD development and associated health outcomes in diagnosed individuals.
METHODS: We followed the Joanna Briggs Institute methodology for this scoping review, conducting searches on PubMed, Scopus, Embase, and Web of Science to identify studies meeting our inclusion criteria (P, population - adults from the general population with or without COPD diagnosis; C, concept - DP; C, context - any setting). Two reviewers screened titles and abstracts, confirmed eligibility through full-text examination, extracted data using Redcap®, and assessed bias risk with the Newcastle Ottawa Scale.
RESULTS: We analyzed 24 studies with sample sizes ranging from 121 to 421,426 individuals aged 20 to 75. Eighty-three percent investigated the role of DP in the COPD etiology, while 16.7 % examined health-related COPD outcomes. Food frequency questionnaires predominated (75 %) in exploring 23 distinct DP. Sixty-seven percent employed a priori-defined DP, focusing on the Mediterranean Diet (MedDiet) and Healthy Eating Index (HEI), while 33.3 % utilized a posteriori-defined DP, mainly represented by the Prudent and Traditional DP. Sixty percent of the studies reported significant associations between DP and COPD risk/odds. However, studies examining DP and COPD patient outcomes produced varied results.
CONCLUSIONS: Most studies focused on assessing COPD risk using a priori-defined DP, particularly emphasizing the Med Diet and HEI. Overall, the studies found that healthy DPs are associated with reduced risk of COPD and improved outcomes in diagnosed patients.

摘要：
目的：关于饮食模式（DP）与COPD风险或健康相关结局之间的关系的研究有限。我们回顾了现有文献，以确定DP是影响COPD发展和诊断个体相关健康结果的潜在因素。
方法：我们遵循了JoannaBriggsInstitute的研究方法，在PubMed上进行搜索，Scopus,Embase,和WebofScience确定符合我们纳入标准的研究(P，人口-一般人群中有或没有COPD诊断的成年人；C，概念-DP；C，上下文-任何设置)。两名审稿人筛选了标题和摘要，通过全文审查确认资格，使用Redcap®提取的数据，并用纽卡斯尔渥太华量表评估偏倚风险。
结果：我们分析了24项研究，样本量为121至421,426名20至75岁的个体。83％的人调查了DP在COPD病因中的作用，而16.7%的人检查了与健康相关的COPD结局。食物频率问卷在探索23种不同的DP方面占主导地位（75％）。67%的人使用先验定义的DP，专注于地中海饮食（MedDiet）和健康饮食指数（HEI），而33.3%的人使用后验定义的DP，主要以谨慎和传统的DP为代表。60%的研究报告了DP和COPD风险/几率之间的显著关联。然而,检查DP和COPD患者结局的研究产生了不同的结果.
结论：大多数研究集中于使用先验定义的DP评估COPD风险，特别强调Med饮食和HEI。总的来说,研究发现,在确诊患者中,健康的DPs与COPD风险降低和预后改善相关.
