某人群死因资料之死亡率潜在寿命损失年数的比较分析

应用死亡率和潜在寿命损失年数（YPLL）两类指标对某人群1996～1998年的死亡资料进行分析。结果显示：YPLL位次和死因顺位有较大差异，意外伤害在死因顺序中居第五位，而在YPLL位次中跃居首位。男女性别YPLL位次基本相同，除了心血管疾病，男性SYPLL率均不同程度地高于女性。提示YPLL能合理地反映低年龄死亡的危害，应综合YPLL和死亡率来评价人群的健康状况。

A Comparative Study of Mortality and Years of Potential Life Lost(YPLL)

Mortality and years of potential life lost(YPLL) are used to analyse deaths of a population in 1996~ 1999.The results showed that the accidental death was the fifth in proportionate mortality ratio, but the first in the rate of YPLL. The YPLL rates in males and females are almost the same. Except for cardiovascular diseases,SYPLL of males in the other diseases is remarkably higher than that of females. It is suggested that YPLL is a reasonable index in re flecting the rish of the low-aged people which we should combine with mortality assess in health status assessment.
