背景——在未来十年中，监测中风死亡率的趋势和模式将至关重要。生命统计方面的两项创新可能使这项任务复杂化，必须引起研究人员和研究报告读者的注意：新的 2000 年年龄标准和国际疾病和相关健康问题统计分类，第 10 次修订版 (ICD-10)。审查摘要 - 对于脑血管疾病，使用 2000 年标准的年龄调整死亡率比使用旧标准高 2.4 倍1940年标准。然而，如果使用相同的年龄标准计算所有年份的比率，则根据 1940 年标准（-35.8%）或 2000 年标准（-34.3%），1979 年至 1995 年的百分比变化相似。改变 2000 年标准的另一个重要影响是减少了按年龄调整的死亡率的黑人/白人差异。在国际疾病分类第九次修订版 (ICD-9)（1979-1998 年）和 ICD-10（1999 年及以后年份）分类之间，未观察到脑血管疾病或心脏病死亡率趋势的重大不连续性。 结论——所有数据用户在评估或呈现一段时间内或各组之间的年龄调整率时，必须谨慎指定所使用的年龄标准。必须检查 1999 年之前与 1999 年或以后年份选择的 ICD 代码的可比性，以区分因编码引起的变化与死亡率水平的真实变化。
Background-Monitoring of trends and patterns of stroke mortality will be of utmost importance in the coming decade. Two innovations in vital statistics may complicate this task and must be brought to the attention of both researchers and readers of research reports: the new Year 2000 Age Standard and the International Statistical Classification of Diseases and Related Health Problems, 10th Revision (ICD-10).Summary of Review-For cerebrovascular diseases, the age-adjusted death rate is 2.4 times higher with the use of the year 2000 standard than with the use of the old 1940 standard. However, if rates for all years are computed with the use of the same age standard, the percent change from 1979 to 1995 is similar according to the 1940 standard (-35.8%) or the year 2000 standard (-34.3%). Another important effect of the change to the year 2000 standard is to reduce black/white differentials in age-adjusted death rates. Major discontinuities are not observed for mortality trends in cerebrovascular disease or heart disease between International Classification of Diseases, Ninth Revision (ICD-9) (1979-1998) and ICD-10 (1999 and following years) classifications.Conclusions-All data users must exercise caution to specify the age standard used when assessing or presenting age-adjusted rates over time or between groups. The comparability of ICD codes chosen for years before 1999 versus 1999 or following years must be checked to distinguish changes due to coding from true changes in mortality levels.
