Abstract

Much evidence on heightened inflammation and social behavior focuses on social withdrawal. Building on recent theory (Muscatell and Inagaki, 2021), we focused instead on the socially affiliative experience of sex. We investigated the interplay between immunology and motivation on sexual well-being among 158 individuals in romantic relationships. Inflammation, indexed by C-reactive protein (CRP), and sexual well-being were measured multiple times over a month. Relational approach motivation (i.e., motivation toward rewards in relationships) was measured at study entry. Results revealed significant associations between CRP and sexual satisfaction and partnered orgasms frequency for those most motivated to approach rewards with their partner. Interaction effects were replicated with relationship-focused psychological correlates of sexual well-being (e.g., touch, shared laughter, social support), but not with individual-focused outcomes (e.g., adapting to change, goal progress). This is one of the first human studies to demonstrate the body and mind coordinate to promote satisfying sexual experiences within romantic relationships.

炎症和关系动机能协调更好的性生活吗?C反应蛋白和关系动机对性福的相互作用
许多关于炎症加剧和社会行为的证据都集中在社会退缩上。基于最近的理论(Muscatell 和 Inagaki,2021 年),我们转而关注性的社会从属体验。我们调查了 158 名处于恋爱关系中的人的免疫学和性动机之间的相互作用。我们在一个月内多次测量了以 C 反应蛋白(CRP)为指标的炎症和性幸福感。在研究开始时测量了关系接近动机(即在关系中获得回报的动机)。结果显示,对于那些最想与伴侣一起获得奖励的人来说,CRP 与性满意度和伴侣性高潮频率之间存在明显的关联。交互效应与以关系为中心的性健康心理相关因素(如抚摸、共享笑声、社会支持)相同,但与以个人为中心的结果(如适应变化、目标进展)不相同。这是第一批证明身体和心理协调促进浪漫关系中令人满意的性体验的人类研究之一。

期刊介绍: Established in 1987, Brain, Behavior, and Immunity proudly serves as the official journal of the Psychoneuroimmunology Research Society (PNIRS). This pioneering journal is dedicated to publishing peer-reviewed basic, experimental, and clinical studies that explore the intricate interactions among behavioral, neural, endocrine, and immune systems in both humans and animals. As an international and interdisciplinary platform, Brain, Behavior, and Immunity focuses on original research spanning neuroscience, immunology, integrative physiology, behavioral biology, psychiatry, psychology, and clinical medicine. The journal is inclusive of research conducted at various levels, including molecular, cellular, social, and whole organism perspectives. With a commitment to efficiency, the journal facilitates online submission and review, ensuring timely publication of experimental results. Manuscripts typically undergo peer review and are returned to authors within 30 days of submission. It's worth noting that Brain, Behavior, and Immunity, published eight times a year, does not impose submission fees or page charges, fostering an open and accessible platform for scientific discourse.
