Completeness of death-count coverage and adult mortality (45q15) for Brazilian states from 1980 to 2010

ABSTRACT: Objective: Assess the completeness of the DataSUS SIM death-count registry, by sex and Brazilian state, and estimate the probability of adult mortality (45q15), by sex and state, from 1980 to 2010. Methods: The study was based on mortality data obtained in the DataSUS Mortality Information System, from 1980 to 2010, and on population data from the 1980, 1991, 2000, and 2010 demographic censuses. The quality assessment of the registry data was conducted using traditional demographic and death distribution methods, and death probabilities were calculated using life-table concepts. Results: The results show a considerable improvement in the completeness of the death-count coverage in Brazil since 1980. In the southeast and south, we observed the complete coverage of the adult mortality registry, which did not occur in the previous decade. In the northeast and north, there were still places with a low coverage from 2000 to 2010, although there was a clear improvement in the quality of data. For all Brazilian states, there was a decline in the probability of adult mortality; we observed, however, that the death probability for males is much higher than that for females throughout the whole analysis period. Conclusion: The observed improvements seem to be related to investments in the public health care system and administrative procedures to improve the recording of vital events.

摘要：研究目的：评估1980年至2010年间，按性别及巴西各州划分的DataSUS SIM死亡计数登记系统的完整性，并估算同期按性别与州划分的成人死亡概率（45q15）。研究方法：本研究依托1980至2010年从DataSUS死亡信息系统获取的死亡数据，以及1980、1991、2000、2010年四次人口普查的人口统计数据。采用传统人口学方法与死亡分布分析法开展登记数据的质量评估，并通过生命表法计算死亡概率。研究结果：结果显示，自1980年以来，巴西死亡计数登记系统的覆盖完整性显著提升。东南部与南部地区的成人死亡登记已实现全面覆盖，这一情况在此前十年尚未出现。2000至2010年间，东北部与北部地区仍存在部分区域登记覆盖率偏低的情况，但数据质量已出现明显改善。所有巴西州的成人死亡概率均呈下降趋势，但在整个分析周期内，男性的死亡概率始终显著高于女性。研究结论：上述改善似乎与公共医疗体系的投入优化，以及旨在完善生命事件登记的行政流程改进密切相关。
