[Analysis on the potential losses of maternal mortality in Sichuan province in 2003].

Objective: To explore the years of potential life lost (YPLL), working lost, valued lost from the main causes of maternal mortality.

Methods: We collected the mortality cases and live births by the surveillance network of maternal mortality in Sichuan province in 2003, and calculated YPLL, average years of life lost (AYLL), working years of potential life lost (WYPLL), valued years of potential life lost (VYPLL) caused by the death.

Results: In 2003, YPLL, AYLL, WYPLL, VYPLL of the maternal mortality were 4016, 43, 2305 and 2608 respectively.
