Abstract

Background

Prior studies have examined how individuals may undermine their partner’s efforts to maintain a healthy diet, but gay couples have not been represented in this work. Additionally, research has not accounted for mixed-weight status [lighter partner (LP) and heavier partner] nor investigated the mechanisms through which undermining is associated with dietary outcomes.

Objective/Design/Measures

Utilising dyadic data from 224 gay married couples across the United States, we tested associations between perceptions of partner’s diet undermining strategies and diet quality with couple food disagreements and depressive symptoms as putative, serial mediators in an actor-partner interdependence mediation model.

Results

Results revealed that more severe diet undermining was associated with both partners’ poorer diet quality, which was explained by more frequent couple food disagreements and higher depressive symptoms for both heavier and LPs.

Conclusion

These findings suggest that undermining strategies are detrimental to both partners’ relational health (increased conflict), emotional health (depressive symptoms) and physical health (diet)—regardless of weight status—and provide valuable targets for prevention and intervention. Our study underscores the interdependence of couple relations in lifestyle changes and specifically highlight the need for health professionals to discuss the partner’s indirect or unintended disruptions to the patient’s plan.

混合体重的老年同性恋夫妇中伴侣饮食破坏与不良饮食之间的关联：二元中介模型

摘要

背景

先前的研究已经研究了个人如何破坏他们的伴侣保持健康饮食的努力，但在这项工作中没有代表同性恋伴侣。此外，研究没有考虑混合体重状态 [较轻的伴侣 (LP) 和较重的伴侣]，也没有调查破坏与饮食结果相关的机制。

目标/设计/措施

利用来自美国各地 224 对同性恋已婚夫妇的二元数据，我们测试了对伴侣饮食破坏策略的看法与饮食质量之间的关联，其中夫妻食物分歧和抑郁症状作为演员-伴侣相互依赖调解模型中的推定连续调解员。

结果

结果显示，更严重的饮食破坏与伴侣双方较差的饮食质量有关，这可以通过更频繁的夫妻食物分歧和较重的人和 LP 的更高的抑郁症状来解释。

结论

这些发现表明，破坏策略对双方的关系健康（冲突增加）、情绪健康（抑郁症状）和身体健康（饮食）——无论体重状况如何——都有害，并为预防和干预提供了有价值的目标。我们的研究强调了生活方式改变中夫妻关系的相互依存关系，并特别强调了卫生专业人员讨论合作伙伴对患者计划的间接或意外干扰的必要性。
