Potentially productive years of life lost (PPYLL) is an impact measure that illustrates the lost that a society suffers as a consequence of deaths of young people or premature deaths.
To study the evolution of PPYLL in adults in the periods 1994-1996 and 1999-2001, according to sex, income quintiles and main diagnostic groups in the communities of Metropolitan Santiago.
Ecological study analyzing the population of Metropolitan Santiago, that represents 36% of the national population. A total of 87,969 deaths in people aged 20 to 79 years were analyzed.
There is a greater amount of PPYLL among the poorest quintiles and men represent the higher number of PPYLL. In the different analyzed periods, all quintiles experienced a reduction in PPYLL. According to diagnosis, endocrine diseases experienced the greater decrease between periods, followed by respiratory disease. Noteworthy was the increase of PPYLL due to infectious diseases. PPYLL due to digestive diseases was 2.3 higher in the poorest quintile, as compared with the wealthiest quintile (20/20 ratio). The ratio for traumatic disease was 1.8.
When comparing both periods, there is a net gain of potentially productive years of life in all income quintiles and in both genders.
潜在生产性寿命损失年数（PPYLL）是一种影响衡量指标，它说明了社会因年轻人死亡或过早死亡而遭受的损失。
根据性别、收入五分位数和圣地亚哥首都大区各社区的主要诊断组，研究1994 - 1996年和1999 - 2001年期间成年人PPYLL的演变情况。
对代表全国36%人口的圣地亚哥首都大区人口进行生态研究。分析了20至79岁人群中的87969例死亡病例。
最贫困五分位数人群的PPYLL数量更多，男性的PPYLL数量更高。在不同分析时期，所有五分位数人群的PPYLL均有所减少。按诊断情况来看，内分泌疾病在各时期之间的降幅最大，其次是呼吸系统疾病。值得注意的是，传染病导致的PPYLL有所增加。最贫困五分位数人群因消化系统疾病导致的PPYLL比最富裕五分位数人群高2.3倍（20/20比率）。创伤性疾病的比率为1.8。
比较两个时期时，所有收入五分位数人群和两性的潜在生产性寿命均有净增加。
