Low subjective social status (SSS) in childhood places one at greater risk of a number of health problems in adulthood. Theoretical and empirical evidence indicates that exposure to supportive parenting may buffer the negative effects of low childhood SSS on adult health. Given the importance of supportive caregivers and close others for the development of attachment orientations throughout the lifespan, attachment theory may be important for understanding why some individuals are resilient to the negative effects of low childhood SSS on adult health while others are not. We examined if attachment anxiety and attachment avoidance altered the association between childhood subjective social status (SSS) and length of telomeres in white blood cells in adulthood. Shorter telomere length is associated with increased risk of age-related diseases including cancer, type 2 diabetes, and cardiovascular disease. Participants (N = 128) completed self-report measures of childhood SSS and attachment orientations, as well as a blood draw. We found that among those with low childhood SSS, low attachment anxiety was associated with longer telomere length in white blood cells in comparison to high attachment anxiety controlling for participant age, sex, race, body mass index, and adult SSS. Among those with high childhood SSS, low attachment anxiety was associated with a slight decrease in telomere length. Attachment avoidance was unrelated to length of telomeres. Such findings provide further evidence for the role that close relationships may have on buffering SSS related health disparities.
童年时期较低的主观社会地位(SSS)会使一个人在成年后患多种健康问题的风险更高。理论和实证证据表明,接受支持性养育可能会缓冲童年低SSS对成年健康的负面影响。鉴于支持性照顾者和亲密他人对整个生命周期依恋取向发展的重要性,依恋理论对于理解为什么有些人能抵御童年低SSS对成年健康的负面影响而另一些人却不能可能很重要。我们研究了依恋焦虑和依恋回避是否改变了童年主观社会地位(SSS)与成年后白细胞端粒长度之间的关联。较短的端粒长度与包括癌症、2型糖尿病和心血管疾病在内的与年龄相关疾病的风险增加有关。参与者(N = 128)完成了童年SSS和依恋取向的自我报告测量,以及一次血液抽取。我们发现,在童年SSS较低的人群中,与高依恋焦虑相比,低依恋焦虑与白细胞端粒长度较长有关,同时控制了参与者的年龄、性别、种族、体重指数和成年SSS。在童年SSS较高的人群中,低依恋焦虑与端粒长度略有下降有关。依恋回避与端粒长度无关。这些发现为亲密关系在缓冲与SSS相关的健康差距方面可能发挥的作用提供了进一步的证据。
