1993 National Mortality Followback Survey

工作摘要：这项机构间协议的目的是支持收集和分析死亡原因和死者在生命最后一年的特征数据，以规划由国家人口统计中心和疾病预防控制中心进行的1993年全国死亡率跟踪调查的1992年预测试和1993年主要调查。这项调查补充了生命统计档案中死亡证明中的信息，并从最近亲属或其他了解死者最后日子的举报人那里获得了死者的特征信息。预试对1992年死亡的大约800名15岁及以上的人进行了调查。主要调查调查了1993年死亡的22 951名15岁及以上的人。其中包括884名百岁老人死亡。2002财政年度的活动集中于数据分析。一项比较1986年和1993年NMFS数据的分析探讨了在两次调查之间的7年期间，诊断为痴呆症的总体变化。死亡率的计算使用来自三个来源的数据——死亡证明上列出的潜在和多种死亡原因，以及从供方访谈中获得的有关痴呆症诊断终生史的问题。对身体和认知功能发病率的估计是通过对被调查者的访谈获得的。结果显示，在95岁之前，老年痴呆患者的终生病史随着年龄的增长而上升，然后下降。1993年报告的痴呆症终生病史比1986年更为普遍。与1986年一样，1993年的死亡证明数据继续低估了痴呆症的死亡率，尽管1993年的女性死亡率高于1986年，无论数据来源如何。然而，痴呆患者的发病率和致残率在同一时期并没有增加。这份手稿正在接受《神经学》杂志的审查。对这次调查的数据进行进一步分析是可能的。

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.
