The link between marital quality and cellular aging remains underexplored. This study examined how both positive and negative marital quality were associated with salivary telomere length among partnered adults in the United States over the age of 50°years. Data were from the 2008 Health and Retirement Study ( = 3203). Ordinary least squares regression was used to estimate the link between marital quality and telomere length. While neither positive nor negative marital quality was significantly associated with telomere length among older women, positive and negative marital quality had an interacting effect on telomere length among men. Specifically, when negative marital quality was low, higher positive marital quality was associated with shorter telomere length, whereas when negative marital quality was high, higher positive marital quality was associated with longer telomere length. The findings speak to the complex nature of intimate partnerships and the implications of these partnerships for cellular aging processes.
婚姻质量与细胞衰老之间的联系仍未得到充分探索。本研究考察了美国 50 岁以上的已婚成年人中,积极和消极的婚姻质量与唾液端粒长度之间的关系。数据来自 2008 年的健康与退休研究(n=3203)。采用普通最小二乘法回归来估计婚姻质量与端粒长度之间的关系。虽然积极和消极的婚姻质量都与女性的端粒长度没有显著相关,但积极和消极的婚姻质量对男性的端粒长度有相互作用。具体来说,当消极的婚姻质量较低时,较高的积极的婚姻质量与较短的端粒长度相关,而当消极的婚姻质量较高时,较高的积极的婚姻质量与较长的端粒长度相关。这些发现反映了亲密伴侣关系的复杂性以及这些关系对细胞衰老过程的影响。
