Studies of health, retirement and living arrangements of the aging population in

描述（由申请人提供）：我们建议使用由父母资助的“中国健康与退休纵向研究（CHARLS）：试点”收集的数据，在nih资助的科学家和LMIC（中国）的研究人员之间开展关于中国健康与老龄化问题的联合合作研究。通过本项目的培训和研究，将大大提高从事该项目的中国研究人员在未来开展健康与老龄化问题高质量科学研究的能力。此外，这种培训将对高收入国家的科学家产生积极的溢出效应，因为我们的中国学员将与美国等高收入国家的学者共同进行一些未来的研究。参与这样的跨国合作研究可以带来很高的回报，使我们在健康和老龄化知识方面取得科学进步。我们刚刚完成了由家长资助的数据收集。数据涵盖了浙江和甘肃两省随机抽取的1575户家庭，以及2951名45岁及以上的个人及其配偶。虽然是试点，但样本量足够大，可以进行严肃的科学分析。CHARLS是中国第一个公开的老年人数据集，其内容如此广泛，而且明确是在HRS之后设计的。我们将重点关注四个研究课题。1. 社会经济地位（SES）与健康不同方面之间的梯度；2. 与人口老龄化相关的某些疾病的漏诊，特别是调查护士所采取的生物测量与报告的医生诊断之间的差异，以及造成这些差异的社会经济地位因素；3. 老年人退休行为及其与健康的关系4. 老年人的生活安排及其与健康的关系。这项研究将主要在中国北京大学进行，作为NIH资助号1R21AG031372-01, 09-30-2007至8-31-2009的延伸。这个提案我们有两个PI团队。联系人PI （Y. Zhao，北京大学）是家长资助的PI。另一位PI是南加州大学的J. Strauss，他是家长补助金的共同PI。家长奖助金的共同赞助人A. Park将担任本计划的共同赞助人。“中国老龄化人口的健康、退休和生活安排研究：来自中国健康与退休纵向研究（CHARLS）试点的初步证据”项目将通过培训年轻的中国学者，使用中国第一个主要的、广泛的、公开的老龄化数据集CHARLS，极大地提高中国健康与老龄化研究的能力。

DESCRIPTION (provided by applicant): We propose to use data collected from "China Health and Retirement Longitudinal Study (CHARLS): Pilot" funded by the parent grant to conduct joint collaborative research between NIH-funded scientists and LMIC (China) researchers on health and aging issues in China. The training and research conducted in this project will greatly increase the abilities of the Chinese researchers engaged in this project to conduct future high-quality scientific research on health and aging issues. This training will, in addition, have positive spillover to high income country (HIC) scientists because some of the future research done by our Chinese trainees will be joint with scholars from high income countries, like the United States. Engaging in such cross-country collaborative research can have high payoffs in leading to scientific advances in our knowledge of health and aging. We have just finished collecting the data funded by the parent grant. The data covers 1,575 randomly selected households in two provinces, Zhejiang and Gansu, and 2,951 individuals 45 and older and their spouses. Although a pilot, the sample size is large enough to enable serious scientific analysis. CHARLS is the first publicly available data set on the elderly in China that is so broad in its content and designed explicitly after the HRS. We will focus on four research topics. 1. The gradients between socio-economic status (SES) and different dimensions of health; 2. Underdiagnoses of certain diseases associated with population aging, specifically, the differences between biological measurements taken by the survey nurse and reported doctor diagnoses, and what SES factors underlie these differences; 3. The retirement behavior of the elderly and its relationship to health; 4. The living arrangements of the elderly and their relationships to health. This research will be done primarily in China at Peking University as an extension of NIH Grant No. 1R21AG031372-01, 09-30-2007 to 8-31-2009. We have a two PI team for this proposal. The contact PI (Y. Zhao, Peking University of China) is PI of the parent grant. The other PI, J. Strauss, University of Southern California, is co-PI of the parent grant. A. Park, co-PI of the parent grant, will serve as co-PI of this project. PUBLIC HEALTH RELEVANCE: Public Health Relevance Statement The project, "Studies of health, retirement and living arrangements of the aging population in China: Initial evidence from the pilot of the China Health and Retirement Longitudinal Study (CHARLS)", will greatly enhance the capacity to do research in health and aging in China by training young Chinese scholars, using the first major broad-purposed, public available data set on aging in China, CHARLS.
