Cohort differences in social life and health: Refreshing the NSHAP sample

描述（由申请人提供）：国家社会生活、健康和老龄化项目（NSHAP）是一项针对老年人的纵向研究，旨在研究社会因素（如亲密关系和社会网络）影响健康和受健康影响的机制。2005- 2006年，从全国代表性的3005名57-85岁社区居民（W1）中收集了问卷调查和生物测量数据。在2010-11年度，这些参考受访者与共同配偶/合伙人（W2）一起再次接受了采访。第三波（W3）将于2015-16年收集，将重新采访所有幸存的参考受访者和W2配偶/伴侣。总的来说，NSHAP的W1、W2和W3为具有全国代表性的老年人样本提供了广泛的、纵向的健康和社会信息。我们的目标是在NSHAP样本中增加一个新的队列，以捕捉独特的和流行病学上有趣的“婴儿潮”队列。资助“婴儿潮一代”（即出生于1948年至1965年的受访者）对样本进行更新，将大大增加NSHAP对各个研究界的价值，为开展创新和有效的健康相关研究开辟关键途径，例如：(1)比较不同出生队列中老年人的社会联系、网络、环境和关系以及这些社会因素与健康的关系；(2)追踪同居与婚姻关系人生历程的队列差异；(3)比较不同年龄出生队列的身体功能、自我评价健康、健康行为、慢性病患病率和生理功能的发展轨迹；(4)跟踪中年向老年的转变；(5)捕捉相关慢性疾病在人群中流行的年龄的种族和民族差异。资金将支持增加2500多名受访者。2015- 2016年增加的年龄在50至67岁之间的受访者将提供具有全国代表性的、关于50至95岁之间的社会关系和健康的高质量数据集，为连续队列研究奠定基础

DESCRIPTION (provided by applicant): The National Social Life, Health and Aging Project (NSHAP) is a longitudinal study of older adults designed to examine the mechanisms by which social factors-such as intimate relationships and social networks-affect and are affected by health. In 2005-06, questionnaire and biomeasure data were collected from a nationally- representative sample of 3,005 community-dwelling adults ages 57-85 (W1). These referent respondents were reinterviewed in 2010-11, together with coresident spouses/partners (W2). A third wave (W3), to be collected in 2015-16, will reinterview all surviving referent respondents and W2 spouses/partners. Collectively, NSHAP's W1, W2 and W3 provide extensive, longitudinal, health and social information for a nationally representative sample of older adults. We aim to add a new cohort to the NSHAP sample to capture the unique and epidemiologically intriguing "Baby Boom" cohort. Funding for refreshing the sample with a new cohort of aging "Baby Boomers" (i.e., respondents born from 1948 through 1965) will substantially increase the value of NSHAP for various research communities, opening up key avenues for conducting innovative and effective health related research, such as: (1) comparing the social connections, networks, environment and relationships of older adults in different birth cohorts and the relationship of these social factors with health; (2) tracing cohort differences in the life courseof cohabitations and marital relationships; (3) comparing trajectories of physical function, self-rate health, health behaviors, prevalence of chronic diseases, and physiological functioning across ages over birth cohorts; (4) tracking the transition from middle-age to older ages; and (5) capturing racial and ethnic differences in the ages at which relevant chronic conditions become prevalent across cohorts. Funding will support adding over 2,500 respondents. The addition of respondents ages 50 to 67 in 2015- 16 will provide a nationally-representative, high-quality data set on social relationships and health for ages 50 to 95, setting the stage for a sequential cohort design. The addition of the Baby Boom cohort will allow researchers to compare health and social outcomes along age, period, and cohort axes. We will harmonize data collection with W3 of NSHAP to form a single, cohesive dataset, including in-home interviews with 1,600 new respondents born between 1948-1965 and their spouses or co-residential romantic partners (n=900). This will yield extensive, nationally representative, self-reported and biomeasure data on multiple cohorts' physical and mental health, physical and cognitive functioning, medication use, and pathways of health and mortality within social contexts, facilitating comparative assessments of health disparities between gender, race, ethnicity and socio- economic status by age within and across cohorts.
