目的：标准预期寿命损失年数（SEYLL）是残疾调整生命年（DALY）疾病负担指标的一个组成部分。SEYLL是根据预期剩余年数计算的，由来自模型寿命表的标准生存率指定。因为每一个死亡都有非零的剩余年数，所以损失的寿命年数永远不会为零，即使在一个达到模型生命表本身的理想预期寿命的人口中也是如此。既然零是无法实现的，那么什么是可接受的寿命损失？该研究计算规范，并检查新西兰的数据对theme.Method：使用模型寿命表与预期80年的男性和82.5年的女性，年的寿命损失的队列，实现模型寿命表的预期进行了评估。考虑了每例死亡和每名人口的寿命损失年数，并评估了年龄标准化、贴现和年龄加权的影响。死亡率和人口普查数据被用来计算实际年的寿命损失在新西兰，这是比较normals.Results：粗年的寿命损失每死亡约为9-10年的人口，实现模型寿命表分布。新西兰欧洲人的寿命损失年数比9-10年的标准多5年;毛利人约21年。使用Segi标准人口进行年龄标准化的结果是，平均年龄约为21岁;毛利人和欧洲人的数值都比这一数字高出约两岁。结论：在新西兰的原油和年龄标准化的YLLs超过了理想的模型生命表规范，特别是在毛利人。标准化有很强的影响力的statistics.Implications：年寿命损失的措施需要考虑对既定的规范。除非这样做，否则这些措施可能看起来比实际情况更不利。
Objectives: Standard expected years of life lost (SEYLL) is a component of the disability adjusted life year (DALY) measure of disease burden. SEYLL is calculated from the expected remaining years, as specified by a normative survivorship that is derived from a model life table. Because every death has non-zero remaining years, years of life lost are never zero, even in a population that achieves the ideal life expectancy of the model life table itself. As zero is unattainable, what is an acceptable years of life lost? The study calculates norms and examines NZ data against them.Method: Using model life tables with expectancy 80 years for men and 82.5 years for women, the years of life lost in cohorts that achieve the model life table expectancy are evaluated. Years of life lost per death and per head of population are considered and the effects of age-standardising, discounting and age-weighting are evaluated. Mortality and Census data are used to compute actual years of life lost in New Zealand, which are compared with the norms.Results: Crude years of life lost per death is about 9-10 years in a population that achieves the model life table distribution. New Zealand European years of life lost are about five years in excess of the 9-10 year norm; Maori about 21 years. The effects of age standardising, using the Segi standard population, give a norm of about 21 years; both Maori and European values are about two years in excess of this figure. Conclusions: Crude and age-standardised YLLs in New Zealand exceed the ideal set by the model life tables norms, especially so in Maori. Age-standardising has a strong influence on the statistics.Implications: Years of life lost measures need to be considered against the established norms. Unless done so, the measures can appear more adverse than they actually are.
