The positive effects of a healthy diet on older adults' health status are well established. Yet, inadequate health outcomes prevail. Insufficient healthy dietary styles may be related to the complexity of lay concepts regarding what constitutes a healthy diet. It is hence of importance to disentangle and understand such concepts in depth. The aim of this qualitative study was to explore diet-related intra-couple dynamics and to reconstruct dietary concepts and associated influencing factors among older couples METHODS: The qualitative sample consisted of 15 German couples with at least one partner aged between 50 and 70 years. Study participants were recruited using theoretical sampling. Dyadic guideline-based interviews were conducted from 2016 to 2017. The transcripts were analyzed by means of the Grounded Theory Method RESULTS: Diverse Dyadic dietary concepts emerged from the data material and were shown to be dynamically influenced - among others - within the context of the couple relationship. Three major components showed to be integral to Dyadic dietary concepts: Ideas of healthy diet, Taste and Body images. Moreover, in all of the couples interviewed, one of the partners developed the role of a "Health Expert", who was consensually considered to have more solid health expertise. Different expressions of the HE with corresponding couple dynamics were identified DISCUSSION: This study demonstrates the relevance of diet-related intra-couple dynamics in shaping Dyadic dietary concepts. Particularly, the role of the "Health Expert" within couples showed to decisively influence such concepts. Future research is needed to gain a greater in-depth knowledge on the related influencing factors and couple dynamics. Public health (nutrition) strategies targeting older couples should address such intra-couple dynamics such as the role the partners play for shaping Dyadic dietary concepts.
健康饮食对老年人健康状况的积极影响已得到充分证实。然而，健康状况不佳的情况仍然普遍存在。健康的饮食习惯不足可能与关于什么构成健康饮食的外行概念的复杂性有关。因此，深入剖析和理解这些概念非常重要。这项定性研究的目的是探讨与饮食相关的夫妻间动态，并重构老年夫妻的饮食观念及相关影响因素。方法：定性样本由15对德国夫妻组成，其中至少有一方年龄在50至70岁之间。研究参与者采用理论抽样法招募。2016年至2017年进行了基于二元准则的访谈。通过扎根理论方法对访谈记录进行分析。结果：从数据材料中出现了多种二元饮食观念，并显示在夫妻关系等背景下受到动态影响。三个主要组成部分被证明是二元饮食观念不可或缺的：健康饮食观念、口味和身体形象。此外，在所有接受访谈的夫妻中，一方扮演了“健康专家”的角色，双方一致认为其拥有更扎实的健康专业知识。识别出了“健康专家”的不同表现形式及相应的夫妻动态。讨论：本研究证明了与饮食相关的夫妻间动态在塑造二元饮食观念中的相关性。特别是，夫妻中“健康专家”的角色对这些观念有决定性影响。需要进一步研究以更深入了解相关影响因素和夫妻动态。针对老年夫妻的公共卫生（营养）策略应关注这种夫妻间动态，比如伴侣在塑造二元饮食观念中所起的作用。
