The indicator of potential years of life lost between ages 1 and 70 (PYLL) is proposed with the primary objective of ranking major causes of premature mortality. This proposal is based on a review of existing mortality indicators and indices and of the history of the concept of potential years of life lost. The method of calculation along with the corresponding rate and the age-adjusted rate are discussed and presented with applications to canadian data and interpretation. Several methodological aspects are discussed, particularly the comparison with more sophisticated approaches based on life tables, which do not appear to alter the ranking of major causes of premature death. This indicator fits well into the category of social indicators and can help health planners define priorities for the prevention of premature deaths. Epidemiological studies could also make use of this indicator of premature mortality. The simplicity of calculation and ease of comprehension should facilitate its use.
提出了1至70岁潜在寿命损失年数（PYLL）这一指标，其主要目的是对过早死亡的主要原因进行排名。该提议基于对现有死亡率指标和指数以及潜在寿命损失年数概念历史的回顾。讨论了计算方法以及相应的率和年龄调整率，并通过加拿大数据的应用和解释进行了展示。讨论了几个方法学方面的问题，特别是与基于生命表的更复杂方法的比较，结果表明这些复杂方法似乎并未改变过早死亡主要原因的排名。该指标非常适合社会指标类别，有助于卫生规划者确定预防过早死亡的优先事项。流行病学研究也可以使用这个过早死亡率指标。计算的简单性和易于理解性应便于其使用。
