DESCRIPTION (provided by applicant): We propose to continue and strengthen the existing Chinese Longitudinal Healthy Longevity Survey (CLHLS) study carried out in 1998, 2000, and 2002. We plan to gather more extensive questionnaire data through conducting two more follow-up waves in 2005 and 2008 with about 7,450, 7,500, and 7,130 interviews to centenarians, non-agenarians, and octogenarians, respectively. Relatively comprehensive data on mortality and health status before dying for the 10,382 oldest-old interviewees aged 80-110 who will have died between 2002 and 2008 waves will be collected through interviewing a close family member of the deceased elders. In the 2005 and 2008 waves, we will also conduct follow-up interviews with about 1,000 younger elders aged 65-79 and about 1,000 elderly interviewees' adult children aged 35-71. As was done in 1998, 2000, and 2002, this largest longitudinal survey study on oldest-old with sub-samples of younger elderly and adult children will be conducted in randomly selected half of the counties/cities of 22 provinces; the population in those provinces constitutes about 85% of the total population of China. This application seeks NIA funds to support the main sample of the oldest-old aged 80-110; the sub-sample of the younger elders and adult children will be covered by Chinese sources. Using conventional and advanced demographic/statistical methods, we plan to analyze the CLHLS data with substantially increased statistical power to be achieved from two more follow-up waves in 2005 and 2008. We aim to gain a better understanding of patterns, trends of change in disability, risk factors and determinants of healthy survival, disability, mortality, and extent of suffering before dying at old ages, especially among the oldest-old. We plan to continue to archive the CLHLS data sets and make them userfriendly and widely available to scientists outside and inside of China. As in 1997-2004, this project will continue to be part of the NIA-supported research network on healthy longevity coordinated by James W. Vaupel and Cindy Owens at Duke University.

描述（由申请人提供）：我们建议继续并加强现有的1998年、2000年和2002年进行的中国纵向健康寿命调查（CLHLS）研究。我们计划在2005年和2008年分别对百岁老人、非百岁老人和80岁老人分别进行7450人、7500人和7130人的问卷调查，收集更广泛的问卷数据。10 382名年龄在80至110岁之间、将在2002年至2008年期间死亡的最年长受访者的死亡率和死前健康状况的相对全面的数据，将通过与已故老人的一名亲密家庭成员进行访谈来收集。在2005年及2008年的两波调查中，我们亦会跟进访问约1,000名年龄介乎65至79岁的较年轻长者，以及约1,000名年龄介乎35至71岁的长者子女。与1998年、2000年和2002年一样，本次规模最大的高龄老人纵向调查研究将在全国22个省（市）随机抽取一半的县（市）进行，分样本为较年轻的老人和成年子女；这些省份的人口约占中国总人口的85%。本申请寻求NIA资助，以支持80-110岁高龄老人为主样本；年龄较小的老人和成年子女的子样本将由中国来源涵盖。
