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中国健康长寿纵向调查（CLHLS）研究在1998年，2000年和2002年进行。我们计划在2005年和2008年再进行两次随访，分别对百岁老人、非百岁老人和百岁老人进行约7,450次、7,500次和7,130次访谈，以收集更广泛的问卷数据。通过对2002年至2008年死亡的10,382名80-110岁高龄老人的近亲属进行访谈，收集其死亡率和临终前健康状况的较全面数据。在2005年及2008年的调查中，我们亦会跟进访问约1，000名65至79岁的较年轻长者，以及约1，000名受访长者的35至71岁成年子女。与1998年、2000年和2002年一样，这次最大规模的以低龄老人和成年子女为子样本的高龄老人纵向调查研究将在22个省的一半县/市进行，这些省的人口约占中国总人口的85%。本申请寻求NIA资金，以支持年龄在80-110岁之间的最年长者的主要样本;年龄较小的老年人和成年子女的子样本将由中国来源覆盖。 使用传统的和先进的人口/统计方法，我们计划分析CLHLS数据，从2005年和2008年的两个后续波实现大幅增加的统计能力。我们的目标是更好地了解残疾的模式、变化趋势、健康生存的风险因素和决定因素、残疾、死亡率以及在老年人，特别是最年长的老年人死亡前的痛苦程度。我们计划继续将CLHLS数据集存档，使其易于使用，并广泛提供给中国国内外的科学家。 与1997-2004年一样，该项目将继续作为国家免疫局支持的健康长寿研究网络的一部分，该研究网络由詹姆斯·W.沃佩尔和辛迪·欧文斯在杜克大学。
