Both experiencing loneliness and having a lonely partner can be psychosocial stressors, with implications for health. Yet, marital support may buffer against the cardiometabolic effects of loneliness. This study examines (1) whether own and/or partner's loneliness predict changes in HbA1c over 4 years and (2) whether marital support moderates these effects. Actor-partner interdependence models analyzed data from 1,854 older couples who provided psychosocial and biomarker data at two timepoints (2008/2012 or 2010/2014) of the Health and Retirement Study. Neither partner's loneliness predicted changes in HbA1c overall. However, significant interactions indicated that both own baseline loneliness and partner's baseline loneliness predicted significant increases to HbA1c over 4 years among those who reported below-average marital support. Both the experience of loneliness and loneliness of a dyadic partner may have longitudinal consequences for cardiometabolic health. However, these effects are contingent upon perceived quality of the marriage, specifically marital support.
无论是自身经历孤独还是伴侣孤独，都可能是社会心理压力源，对健康有影响。然而，婚姻支持可能缓冲孤独对心血管代谢的影响。本研究考察了：（1）自身和/或伴侣的孤独感是否会预测 HbA1c 在 4 年内的变化；（2）婚姻支持是否会调节这些影响。 采用主体间依存模型分析了来自健康和退休研究（Health and Retirement Study）两个时间点（2008/2012 或 2010/2014）的 1854 对老年夫妇的心理社会和生物标志物数据。伴侣的孤独感并不预示 HbA1c 的总体变化。然而，显著的交互作用表明，在报告婚姻支持低于平均水平的人群中，自身的基线孤独感和伴侣的基线孤独感都预示着 HbA1c 在 4 年内显著增加。自身的孤独感和伴侣的孤独感都可能对心血管代谢健康有纵向影响。然而，这些影响取决于对婚姻的感知质量，特别是婚姻支持。
