DESCRIPTION (provided by applicant): The Longitudinal Aging Study in India (LASI) is a multidisciplinary, internationally harmonized panel study designed to be nationally representative of India's population aged 45 and older. LASI collects information conceptually comparable to that gathered by the Health and Retirement Study (HRS) and its sister surveys in Asia, Europe, and elsewhere. LASI has brought innovations related to social connectedness, expectations, informal labor market activity, and pension participation. LASI also collects physical measures of health, including dried blood spot (DBS) specimens. Fieldwork for a four-state pilot study funded by the National Institute on Aging (1R21AG032572-01) was successfully implemented in late 2010. Building on the success of the LASI pilot survey, we will implement the first two waves of a large-scale, nationally representative panel survey on aging, health, and retirement in India, with sufficient statistical power to test hypotheses and make meaningful inferences at the national and (large) state level, and in key subpopulations. LASI will allow a better understanding of the determinants and consequences of India's population aging processes and will inform the design of appropriate evidence-based policies to address key challenges associated with population aging. Our public, internationally harmonized data will also allow for cross-national comparative studies on aging. We will field the full-scale, national LASI survey in 15 states, which together make up more than 90% of India's population. The survey instrument will be based on the pilot survey instrument, which was carefully designed to collect information compatible with other HRS-type surveys, while fully capturing key contextual characteristics of India. The target sample for LASI is non- institutionalized Indian residents aged 45 and older and their spouses (irrespective of age). We will draw 18,000 age-qualifying individuals from a stratified, multi-stage, area probability sampling design. Efforts are well unde way to raise additional, non-NIA/NIH funding to extend LASI coverage to India's smaller states and increase sample size and to thereby allow for a more extensive set of state-level inferences and cross-state comparisons. Wave 1 of LASI survey data will be collected in 2013-2014 through face-to-face interviews using Computer Assisted Personal Interviewing. We will then develop and test a longitudinal survey instrument and methods that will be appropriate for follow-up waves, using the pilot sample. Based on the knowledge gained from Wave 1 and the longitudinal methods study using the pilot sample, we will implement Wave 2 in 2015- 2016. In the course of implementing Wave 2, we will seek to follow best practices from the Indonesia Family Life Study, which achieved a 6% attrition rate. Descriptive and analytic studies of the data will be performed, providing insights for scientific researchers and policy makers in India and beyond. De-identified and cleaned data will be made publicly available within one year of fieldwork completion, enabling scientists both within and outside India to use the rich LASI data. Through comparative studies, LASI will enrich scientific insights and policy development in countries besides India. In particular, LASI will provide new research opportunities in the United States and in countries that host comparable HRS-type surveys, such as China and Indonesia.

描述（由申请人提供）：印度纵向老龄化研究 (LASI) 是一项多学科、国际协调的小组研究，旨在代表印度全国 45 岁及以上人口。 LASI 收集的信息在概念上与健康与退休研究 (HRS) 及其在亚洲、欧洲和其他地方的姊妹调查收集的信息相当。 LASI 带来了与社会联系、期望、非正式劳动力市场活动和养老金参与相关的创新。 LASI 还收集健康的物理测量数据，包括干血斑 (DBS) 样本。由国家老龄化研究所 (1R21AG032572-01) 资助的四个州试点研究的实地工作于 2010 年底成功实施。在 LASI 试点调查成功的基础上，我们将实施前两波大规模、关于印度老龄化、健康和退休的全国代表性小组调查，具有足够的统计能力来检验假设并在国家和（大）邦层面做出有意义的推论，并在关键方面亚人群。 LASI 将使人们更好地了解印度人口老龄化过程的决定因素和后果，并将为设计适当的循证政策提供信息，以应对与人口老龄化相关的关键挑战。我们公开的、国际统一的数据也将允许对老龄化问题进行跨国比较研究。我们将在 15 个邦开展全面的全国 LASI 调查，这些邦占印度人口的 90% 以上。该调查工具将基于试点调查工具，该工具经过精心设计，旨在收集与其他 HRS 类型调查兼容的信息，同时充分捕捉印度的关键背景特征。 LASI 的目标样本是 45 岁及以上的非住院印度居民及其配偶（无论年龄）。我们将从分层、多阶段、区域概率抽样设计中抽取 18,000 名符合年龄条件的个体。目前正在努力筹集额外的非 NIA/NIH 资金，以将 LASI 覆盖范围扩大到印度较小的邦并增加样本量，从而进行更广泛的邦级推论和跨邦比较。第一波 LASI 调查数据将于 2013 年至 2014 年通过使用计算机辅助个人访谈的面对面访谈收集。然后，我们将使用试点样本开发和测试适合后续波浪的纵向调查仪器和方法。基于从第一波中获得的知识以及使用试点样本进行的纵向方法研究，我们将在 2015-2016 年实施第二波。在实施第二波的过程中，我们将寻求遵循印度尼西亚家庭生活研究的最佳实践，达到了 6% 的流失率。将对数据进行描述性和分析性研究，为印度及其他地区的科学研究人员和政策制定者提供见解。去识别化和清理后的数据将在实地工作完成后一年内公开，使印度国内外的科学家能够使用丰富的 LASI 数据。通过比较研究，LASI 将丰富印度以外国家的科学见解和政策制定。特别是，LASI 将在美国和开展类似 HRS 类型调查的国家（例如中国和印度尼西亚）提供新的研究机会。
