Social Influences on Early Adult Stress Biomarkers

我们项目的目标是对社会背景、压力和健康进行人口层面的调查。 我们将多种压力生物标志物与来自社会和社会的当前理论和测量工具相结合。 行为科学，以更好地理解社会环境如何“深入人心”地影响压力 和年轻人的健康。我们使用来自四波全国青少年纵向研究的数据 健康（Add Health）追求三个目标：1）检查多个主观之间的相互关系 以及压力的生理测量； 2) 调查社会经济地位、邻里关系的衡量标准如何 童年/青春期以及向成年过渡期间的质量和人际关系 影响成年早期的压力； 3）测试社会因素联合影响的相互竞争的理论模型 经济状况、邻里质量和人际关系对压力的影响。我们考察主观 压力测量，包括感知压力、抑郁症状和焦虑症状 作为内分泌、心血管、代谢、免疫和炎症活动的生理测量。我们 利用 Add Health 数据集的广度和深度来进行最全面的调查 迄今为止关于社会压力如何影响身心健康的调查。另外，大样本 Add Health 的规模以及种族、民族和经济多样性使我们能够调查 压力导致健康差异。压力是发病率和死亡率的主要原因，调查 社会环境影响人类健康的生理机制可以帮助研究人员， 临床医生和政策制定者： a) 识别不利的社会心理环境； b) 更好地理解 病前和疾病途径； c) 告知干预措施以减少暴露于压力源、减少 压力源对生理的不利影响，并防止与压力相关的疾病的出现。

The goal of our project is to conduct a population-level investigation of social contexts, stress, and health. We integrate multiple biomarkers of stress with current theory and measurement tools from the social and behavioral sciences to gain a better understanding of how social contexts "get under the skin" to affect stress and health in young adults. We use data from four waves of the National Longitudinal Study of Adolescent Health (Add Health) in pursuit of three objectives: 1) Examine the interrelations among multiple subjective and physiological measures of stress; 2) Investigate how measures of socio-economic status, neighborhood quality, and interpersonal relationships in childhood/adolescence and over the transition to adulthood influence stress in early adulthood; and 3) Test competing theoretical models of the joint influence of socio- economic status, neighborhood quality, and interpersonal relationships on stress. We examine subjective measures of stress, including perceived stress, symptoms of depression, and symptoms of anxiety, as well as physiological measures of endocrine, cardiovascular, metabolic, immune, and inflammatory activity. We take advantage of the breadth and depth of the Add Health dataset to conduct the most comprehensive investigation to date of how social stress affects physical and mental health. Additionally, the large sample size and racial, ethnic, and economic diversity of Add Health allow us to investigate the extent to which stress leads to health disparities. Stress is a major contributor to morbidity and mortality, and investigating the physiological mechanisms through which social contexts affect human health can help investigators, clinicians, and policy makers to: a) identify adverse psychosocial environments; b) better understand predisease and disease pathways; and c) inform interventions to reduce exposure to stressors, reduce the adverse impact of stressors on physiology, and prevent the emergence of stress-related disorders.
