The study aims to assess two approaches that apply the empirical completeness method to generate age-specific mortality statistics from incomplete death registration systems.
We use the empirical completeness method to calculate all-age death registration completeness, which is used with a model life table to generate mortality statistics and age-specific completeness using (1) the conventional method and (2) the equivalent deaths method. The results are compared with a capture-recapture (C-RC) study and three alternative mortality estimates for Brazilian states, and C-RC studies in Thailand, Oman and Vietnam, which independently estimate the level and age pattern of mortality or completeness.
The empirical completeness method produces similar estimates of all-age completeness of registration to the C-RC studies. Compared with C-RC studies, at 15-59 years, the conventional method's estimates of mortality and completeness are more concordant, while at 60-84 years the equivalent death method's estimates are closer. Estimates of life expectancy from the two approaches each have similar concordance with the C-RC studies. For male adult mortality in Brazilian states, there is relatively strong average correlation of this study's estimates with three alternative estimates.
The two approaches produce mortality statistics from incomplete data that are mostly concordant with C-RC studies, and can be most usefully applied to subnational populations.
本研究旨在评估两种应用经验完整性方法从不完整死亡登记系统生成特定年龄死亡率统计数据的方法。
我们使用经验完整性方法来计算全年龄段的死亡登记完整率，并用模型生命表生成死亡率统计数据和特定年龄的完整性，方法是使用（1）常规方法和（2）等效死亡方法。结果与捕获-再捕获（C-RC）研究和巴西各州的三种替代死亡率估计值进行了比较，并与泰国、阿曼和越南的 C-RC 研究进行了比较，这些研究独立估计了死亡率或完整性的水平和年龄模式。
经验完整性方法产生的全年龄段登记完整率估计与 C-RC 研究相似。与 C-RC 研究相比，在 15-59 岁年龄组，常规方法的死亡率和完整性估计更一致，而在 60-84 岁年龄组，等效死亡方法的估计更接近。两种方法的预期寿命估计值与 C-RC 研究的一致性相似。对于巴西各州的男性成年人死亡率，本研究的估计值与三种替代估计值具有相对较强的平均相关性。
这两种方法从不完整的数据中生成死亡率统计数据，与 C-RC 研究大多一致，并且最适用于次国家级人口。
