China Health and Retirement Longitudinal study

摘要 该更新提案旨在资助中国健康与退休研究的第5波（2021年）和第6波（2024年） （查尔斯）。其总体目标是进一步发展一个一流的纵向，公众使用，老龄化调查为中国 这与世界其他地区的HRS老龄化调查相当。 CHARLS国家基线调查于2011 - 12年进行。这是一项全国性的调查 其中包括每户一名45岁以上的人及其配偶（共计17 708人） 生活在中国30个县/区中的28个县/区的450个村庄/城市社区的10，257户家庭中 除西藏外的其他省份第2、3和4波分别于2013年、2015年和2018年投入使用。约86.5% 在第4波中再次联系了第1波答复者。2014年，一个收集生活史数据的特殊波浪被派往现场， 利用中国国家自然科学基金（NSFC）和其他来源的资源。在第四波中， 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症（ADRD）的各个方面， 60岁及以上的受访者。我们将继续CHARLS HCAP为所有受访者60和以上的第6波， 第5波中的受访者子集。 CHARLS的第5波和第6波将为那些从第1波开始的人提供13年的数据。 不仅可以检查生命早期发生的事件的长期后果，而且还可以跟踪 这些结果的时间路径。这也将有助于研究健康行为之间的因果关系， 环境或政策变化和健康结果。CHARLS数据的每一波发布， 在数据收集结束后的一年半内，免费公开。这种做法将持续到 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.
