China Health and Retirement Longitudinal study

摘要 这项续签建议是为中国健康与退休研究的第五波(2021年)和第六波(2024年)提供资金 (Charls)。总体目标是进一步开展一流的纵向、公益性、老年性中国调查 这与世界其他地区的HRS老龄化调查结果不相上下。 CHARLS国家基线调查是在2011-12年度进行的。这是一项具有全国代表性的调查 这包括每个45岁或45岁以上的家庭一人及其配偶(总计17708人) 中国的30个家庭中有28个生活在150个县/区的450个村庄/城市社区的10,257户家庭 西藏以外的省份。第二波、第三波和第四波分别于2013年、2015年和2018年部署。约86.5%的 第一波受访者在第四波中被重新联系。2014年，一次收集生活史数据的特殊波被派往现场， 利用国家自然科学基金中国等来源的资源。在第四波中，我们 增加了协调认知评估协议(HCAP)，与美国、墨西哥、 英国、南非和印度；测量阿尔茨海默病和相关痴呆(ADRD)的维度 受访者年龄在60岁及以上。我们将在第6波中继续为所有60岁及以上的受访者提供CHARLS HCAP，并 第5波受访者的子集。 CHARLS的第5波和第6波将为第1波开始的那些人提供13年的数据。 不仅允许检查生命早期发生的事件的长期后果，而且还允许遵循 这些结果的时间路径。这也将使研究健康行为之间的因果联系成为可能， 环境或政策的变化和健康结果。CHARLS数据的每一波总是被发布 在数据收集结束后一年半内免费公开。这一做法将持续到 未来。

ABSTRACT This renewal proposal is to fund waves 5 (2021) and 6 (2024) of the China Health and Retirement Study (CHARLS). The overarching goal is to further develop a first rate longitudinal, public use, aging survey for China that is comparable with HRS aging surveys from other parts of the world. The CHARLS national baseline survey was conducted in 2011-12. It is a nationally representative survey that includes one person per household aged 45 years of age or older and their spouse (totaling 17,708 individuals) living in 10,257 households in 450 villages/urban communities in 150 counties/districts in 28 of China’s 30 provinces excluding Tibet. Waves 2, 3 and 4 were fielded in 2013, 2015 and 2018 respectively. Some 86.5% of wave 1 respondents were re-contacted in wave 4. A special wave to collect life history data was fielded in 2014, using resources from the National Natural Science Foundation of China (NSFC) and other sources. In wave 4 we added a Harmonized Cognitive Assessment Protocol (HCAP), harmonized to similar efforts in the US, Mexico, England, South Africa and India; to measure dimensions of Alzheimer’s Disease and related dementias (ADRD) for respondents 60 and over. We will continue CHARLS HCAP for all respondents 60 and over in wave 6 and for a subset of respondents in wave 5. Waves 5 and 6 for CHARLS would provide data over a 13 year period for those beginning in wave 1.This will allow not only examining longer-run consequences of events that occurred earlier in life, but also to follow the time-path of these outcomes. This will also enable research on causal links between health behaviors, environment or policy changes and health outcomes. Each wave of the CHARLS data has always been released publicly, for free, within one and one half years of the end of data collection. This practice will continue into the future.
