1993 National Mortality Followback Survey

工作概述：这项机构间协议的目的是支持收集和分析关于死亡原因和最后一年死者特征的数据，以规划由疾病控制与预防中心国家卫生服务中心进行的1993年全国死亡率回溯调查的1992年预测和1993年主要调查。这项调查补充了生命统计档案中死亡证明的信息，补充了从死者的近亲或其他知悉死者最后日子的线人那里获得的死者特征信息。预试检查了1992年死亡的大约800名15岁及以上的人的死亡情况。主要调查检查了1993年死亡的22,951名15岁及以上的人的死亡情况。这包括884名百岁老人的死亡。2002财政年度期间的活动主要集中在数据分析上。一项对1986年和1993年NMFS数据进行比较的分析探索了在两次调查之间的7年期间，被诊断为痴呆症的总变化。死亡率的计算使用了三个来源的数据--死亡证明上列出的潜在和多种死因，以及来自举报人面谈的关于痴呆症诊断的终生病史的问题。对身体和认知功能的发病率的估计是从告密者访谈中获得的。结果显示，痴呆患者的终生痴呆史随着年龄的增长而增加，直到95岁，然后下降。1993年报告的痴呆症终生病史比1986年更常见。与1986年一样，1993年死亡证明数据仍然低估了痴呆症的死亡率，尽管女性的死亡率在1993年高于1986年，无论确定的来源是什么。然而，在同一时期，痴呆症死者的发病率和残疾并没有增加。这篇手稿正在接受《神经学》杂志的审查。对这项调查数据的其他分析是可能的。

Summary of Work: The purpose of this interagency agreement was to support the collection and analysis of data on cause of death and characteristics of decedents in the last year of life in the planning of the 1992 Pretest and 1993 Main Survey of the 1993 National Mortality Followback Survey (NMFS), conducted by NCHS, CDC. This survey supplements information from death certificates in the vital statistics file with information on characteristics of the decedents obtained from the next of kin or other informant knowledgable about the decedents' last days. The pretest examined approximately 800 deaths of individuals aged 15 years and over who died in 1992. The main survey examined 22,951 deaths of individuals aged 15 years and over who died in 1993. This includes 884 deaths to centenarians. Activities during FY 2002 have been concentrated on data analysis. An analysis comparing the 1986 and 1993 NMFS data explored aggregate change over time in diagnosed dementia over the 7-year period between the two surveys. Mortality rates were computed using data from three sources -- the underlying and multiple causes of death as listed on the death certificate, and questions concerning the lifetime history of dementia diagnosis from the informant interviews. Estimates of morbidity in physical and cognitive function were obtained from the informant interviews. Results showed the lifetime history of dementia among decedents rose with age up to age 95 and then declined. The reported lifetime history of dementia was more common in 1993 than in 1986. In 1993 death certificate data continued to underestimate dementia mortality as it did in 1986, although for females the mortality rates were higher in 1993 than in 1986, regardless of the source of ascertainment. Morbidity and disability among the demented decedents did not show increases over the same time period, however. This manuscript is under review by the journal Neurology. Additional analyses of data from this survey are possible.
