潜在寿命损失年数（YPLL）的概念涉及估计一个人如果没有过早死亡的平均寿命。这一衡量标准被用来帮助量化过早死亡造成的社会和经济损失，并被用来强调影响较年轻年龄组的具体死亡原因。YPLL固有地包含死亡年龄，其计算通过将每个年龄的死亡值应用于死亡总数来数学加权。计算YPLL的方法因作者而异，每个作者都对过早死亡的主要原因进行了不同的排名。人们可以选择心脏病，癌症或事故作为过早死亡的主要原因，这取决于使用哪种方法。在使用这一衡量标准方面的混乱源于对计算中固有的价值体系的误解，以及对应适用于每个死亡年龄的价值观的不同看法。
The concept of years of potential life lost (YPLL) involves estimating the average time a person would have lived had he or she not died prematurely. This measure is used to help quantify social and economic loss owing to premature death, and it has been promoted to emphasize specific causes of death affecting younger age groups. YPLL inherently incorporates age at death, and its calculation mathematically weights the total deaths by applying values to death at each age. The method of calculating YPLL varies from author to author, each producing different rankings of leading causes of premature death. One can choose between heart disease, cancer, or accidents as the leading cause of premature death, depending on which method is used. Confusion in the use of this measure stems from a misunderstanding of the value system inherent in the calculation, as well as from differing views as to values that should be applied to each age at death.
