DESCRIPTION (provided by applicant): This proposal is responsive to PA-10-139 entitled, "Secondary Analyses of Social and Behavioral Datasets in Aging (R03)". The long-term goals of our research program are to examine the impact of chronic stress and psychosocial factors on metabolic dysregulation and cardiovascular disease (CVD) risk and to investigate the biologic mechanisms underlying these associations. The PI has an active study (1R21HL091290) using data from the NIA/NINR-funded Study of Women's Health across the Nation (SWAN), and the ancillary SWAN Mental Health Study, to investigate the impact of depression on adiponectin and leptin. Adiponectin is the most abundant anti-inflammatory adipocytokine secreted by adipocytes and leptin is a pro-inflammatory adipocytokine intimately involved in metabolic regulation, energy balance, and autonomic nervous system functioning. The proposed study will significantly enhance this work by expanding the breadth of psychosocial measures available to us. We propose to utilize additional existing SWAN data on multiple measures of chronic stress (financial strain, perceived stress, stressful life events, perceived discrimination) and psychosocial functioning (hostility, anxiety, optimism, social support), together with the adiponectin and leptin data from the PI's active R21, to examine both cross-sectional and 5-year longitudinal associations between stress/psychosocial factors and these critical obesity-related inflammatory markers in 581 SWAN participants (225 black women, 356 white women). Aims are: 1) to determine if chronic stress is associated with baseline and 5-year changes in adiponectin and leptin levels; and 2) to determine if psychosocial factors are associated with baseline and 5-year changes in adiponectin and leptin levels. Secondary aims are to examine pathways among the measures of stress and psychosocial functioning, including depression, and these obesity-related inflammatory markers, and to investigate potential race differences in the hypothesized associations. The project will provide crucial data that will foster development of a more comprehensive and integrative biopsychosocial framework to guide future studies and achieve the goals of our research program. By adding to a study already in progress (R21HL091290) and utilizing the richness of the existing SWAN data, the proposed study will allow a fuller characterization of psychological and social processes that may relate to important adipokine biomarkers in women. Thus, this work has the potential to greatly expand our understanding of a critical inflammatory pathway by which stress and psychosocial factors may contribute to metabolic dysregulation and CVD risk in women. Moreover, the study addresses the critical public health problems of obesity and cardiovascular disease and thus has high public health relevance. PUBLIC HEALTH RELEVANCE: The proposed study has high public health relevance as it will yield important information about pathways by which stress and psychosocial factors may lead to obesity, diabetes and heart disease in women. These diseases are leading causes of death and disability in the US and worldwide. Knowledge gained likely will contribute to future treatment and prevention efforts for these critical public health problems.

描述（由申请人提供）：本提案响应题为“老龄化社会和行为数据集的二次分析 (R03)”的 PA-10-139。我们研究计划的长期目标是检查慢性压力和心理社会因素对代谢失调和心血管疾病 (CVD) 风险的影响，并调查这些关联背后的生物学机制。 PI 正在进行一项积极的研究 (1R21HL091290)，利用 NIA/NINR 资助的全国妇女健康研究 (SWAN) 和辅助 SWAN 心理健康研究的数据来调查抑郁症对脂联素和瘦素的影响。脂联素是脂肪细胞分泌的最丰富的抗炎脂肪细胞因子，瘦素是一种促炎脂肪细胞因子，与代谢调节、能量平衡和自主神经系统功能密切相关。拟议的研究将通过扩大我们可用的心理社会措施的广度来显着加强这项工作。我们建议利用现有的关于慢性压力（财务压力、感知压力、压力生活事件、感知歧视）和心理社会功能（敌意、焦虑、乐观、社会支持）的多种衡量指标的 SWAN 数据，以及脂联素和瘦素数据PI 的主动 R21，以检查 581 名 SWAN 参与者（225 名黑人女性，356 名白人女性）。目的是： 1) 确定慢性压力是否与脂联素和瘦素水平的基线和 5 年变化相关； 2) 确定心理社会因素是否与脂联素和瘦素水平的基线和 5 年变化相关。次要目标是检查压力和心理社会功能测量之间的途径，包括抑郁症和这些与肥胖相关的炎症标志物，并调查假设关联中潜在的种族差异。该项目将提供关键数据，促进更全面和综合的生物心理社会框架的发展，以指导未来的研究并实现我们研究计划的目标。通过补充一项已经在进行的研究 (R21HL091290) 并利用现有 SWAN 数据的丰富性，拟议的研究将能够更全面地描述可能与女性重要脂肪因子生物标志物相关的心理和社会过程。因此，这项工作有可能极大地扩展我们对关键炎症途径的理解，压力和社会心理因素可能通过该途径导致女性代谢失调和心血管疾病风险。此外，该研究解决了肥胖和心血管疾病等关键公共卫生问题，因此具有高度的公共卫生相关性。 公共健康相关性：拟议的研究具有高度的公共健康相关性，因为它将提供有关压力和社会心理因素可能导致女性肥胖、糖尿病和心脏病的途径的重要信息。这些疾病是美国和全世界死亡和残疾的主要原因。获得的知识可能有助于未来这些关键公共卫生问题的治疗和预防工作。
