Background and Purpose The present study aimed to examine associations between different types of relationship functioning and disordered eating behaviors (DEBs) in the everyday lives of sexual minority women in same-sex relationships—an at-risk population that has not been assessed in this context. Methods Participants included 321 young sexual minority women (Mage = 27.56, SD = 3.67) in same-sex relationships who completed surveys assessing their daily relationship functioning and DEB use each day for a 14-day daily diary period. Multilevel structural equation modeling was used to examine daily-, person-, and couple-level associations among women’s daily relationship functioning (general relationship functioning, positive and negative relational behaviors they and, separately, their partners engaged in) and DEBs (overeating, loss of control eating, emotional eating, and dietary restriction). Results Results generally indicated that more positive and less negative daily relationship functioning across all assessed constructs was associated with less same-day emotional eating. In contrast, associations between all daily relationship functioning constructs and loss of control eating were not significant, nor were any relationship functioning-DEB associations at the couple level. More circumscribed patterns of association were identified for associations between the relationship functioning constructs, and overeating and dietary restriction. Conclusions Collectively, these findings provide insight into how aspects of daily relationship functioning map onto sexual minority women’s daily engagement in DEBs that are linked to poor health long-term, and directions for future research and clinical practice that may warrant consideration moving forward to help advance the evidence-base and care for this historically overlooked and underserved population.

同性关系中性少数女性的日常关系功能和饮食失调行为

背景和目的本研究旨在探讨同性关系中性少数女性日常生活中不同类型的关系功能与饮食失调行为（DEB）之间的关联——该群体是一个尚未在这方面进行评估的高危人群。方法 参与者包括 321 名处于同性关系中的年轻性少数女性（Mage = 27.56，SD = 3.67），她们在为期 14 天的日记周期中完成了评估其日常关系功能和 DEB 使用情况的调查。使用多级结构方程模型来检查女性日常关系功能（一般关系功能、她们及其伴侣分别从事的积极和消极关系行为）和DEB（暴饮暴食、失落）之间的日常、个人和夫妻层面的关联。控制饮食、情绪饮食和饮食限制）。结果结果通常表明，在所有评估的结构中，更积极和更少消极的日常关系与当天情绪化饮食的减少有关。相比之下，所有日常关系功能结构与饮食失控之间的关联并不显着，夫妻层面上的任何关系功能-DEB关联也不显着。关系功能结构与暴饮暴食和饮食限制之间的关联被确定为更受限制的关联模式。结论 总的来说，这些发现提供了关于日常关系功能的各个方面如何映射到性少数女性日常参与与长期健康状况不佳相关的 DEB 的见解，以及未来研究和临床实践的方向，这些方向可能值得考虑，以帮助推进对这个历史上被忽视和服务不足的人群的证据基础和关怀。
