Objectives: The purpose of this qualitative study was to explore factors associated with the ability of people with PD to perform food-related activities (FRAs). Methods: Eleven dyads, older adults with Parkinson disease (PD) and their care-partners (n = 22), completed virtual semi-structured interviews guided by the Social Cognitive Theory (SCT) that were independently analyzed by two coders via directed content analysis. Results: The following themes were identified—(1) Personal: perception of a healthy diet, perception of how nutrition influences PD, confidence in following a healthy diet, and barriers to performing FRA; (2) Environmental: previous sources of nutrition information and willingness to changing their diet with a registered dietitian; and (3) Behavioral: modifications to FRA due to food-medication interactions, and skills necessary to maintain a healthy diet. Discussion: Findings from this study highlight the need for nutrition intervention research to inform evidence-based guidelines in order to provide tailored education for people with PD and care-partners.

目标：这项定性研究的目的是探索与 PD 患者进行食物相关活动 (FRA) 的能力相关的因素。方法： 11 对患有帕金森病 (PD) 的老年患者及其护理伙伴 ( n = 22)，完成了由两名编码员通过定向内容分析独立分析的社会认知理论 (SCT) 指导下的虚拟半结构化访谈. 结果：确定了以下主题——(1) 个人：对健康饮食的看法、对营养如何影响 PD 的看法、对遵循健康饮食的信心以及执行 FRA 的障碍；(2) 环境：以前的营养信息来源和通过注册营养师改变饮食的意愿；(3) 行为：由于食物-药物相互作用而对 FRA 进行的修改，以及维持健康饮食所需的技能。讨论：这项研究的结果强调了营养干预研究的必要性，以便为循证指南提供信息，以便为 PD 患者和护理伙伴提供量身定制的教育。
