National Social Life, Health, and Aging Project: Anaylsis of Wave 1 and Wave 2

国家社会生活、健康和老龄化项目（NSHAP）调查了社会关系与老年人健康之间的联系，对两者都进行了广泛而深入的定义。该项目的核心是一个具有全国代表性的3,005名社区居住成年人样本，从2005/6 （W1）中获得了广泛的访谈和生物测量数据，当时他们年龄在57-85岁之间。2010/11年（W2）的第二波数据收集再次查看了所有幸存的参与者、他们的配偶和共同伴侣（N=3,377），并建立了关于美国老年人健康和社会生活的纵向、基于人口的数据。W1油田的数据是在该油田开采期结束约一年后公布的。W2数据收集工作于2011年6月完成，初步数据于2011年8月提供给调查人员，预计将于2012年早春向研究公众发布数据。该提案寻求资金，以延长IVIERIT奖R37 AG030481，国家社会生活，健康和老龄化项目（NSHAP），为期五年。调查小组提出了一系列分析，重点是重新定义老年人口的健康，健康和福祉的变化，以及在二元和社会网络中产生健康。这些都是正在进行的工作，开始使用来自第一波NSHAP的数据。总之，这些分析使我们能够将老年人口的健康特征划分为健康类别，其特征是健康维度的价值，包括器官系统、免疫功能、健康行为、心理状态和感觉运动功能，每一个都有多个指标。它们将使我们能够预测健康类别的死亡率，并检查健康类别之间随时间的变化。提出的分析将使我们能够在亲密关系（主要是婚姻）和老年社会网络中建立健康产生的模型，并尽可能地检查睡眠是社会世界影响健康的一种机制。

The National Social Life, Health and Aging Project (NSHAP) investigates the link between social connections and health at older ages, applying broad and deep definitions of both. At the heart of this project is a nationally-representative sample of 3,005 community-dwelling adults, from whom extensive interview and biomeasure data were obtained in 2005/6 (W1) when they were ages 57-85. A second wave of data collection in 2010/11 (W2) reinter viewed all surviving participants, their spouses and coresident partners (N=3,377), and established longitudinal, population-based data on health and social life among older Americans. The data from W1 were made publicly available about a year after the close of the field period. W2 data collection was completed in June 2011, preliminary data were made available to the investigators in August 2011, and a release of the data to the research public is expected in early Spring 2012. This proposal seeks funding to extend IVIERIT Award R37 AG030481, The National Social Life, Health and Aging Project (NSHAP), for five years. The team of investigators proposes a series of analyses, focused on reconceptualizing health in the older population, changes in health and well-being, and the production of health in the dyad and social networks. Each of these is an ongoing effort begun using data from the first wave of NSHAP. Together these analyses allow us to characterize the health of the older population into health classes, characterized by values on health dimensions including organ systems, immune function, health behaviors, psychological states and sensory motor function, each with multiple indicators. They will allow us to predict mortality from health class, and to examine transitions between health classes over time. The proposed analyses will allow us to model the production of health within intimate relationships, predominantly marriages, and social networks at older ages, and to examine sleep as possible a mechanism through which the social world affects health.
