Objective       To analyze perinatal mortality in Chongqing from 2006 to 2015 for providing improved preventive care measures in reducing the incidence.  Methods        Perinatal death including fetal death with at least 28 weeks of gestations and infant death occurred less than 7 d after birth from 2006 to 2015 was dynamically monitored and analyzed.   Results       The average perinatal mortality (PMR) in Chongqing from 2006 to 2015 was 9.07  with a total of 11 039 cases

and the PMR was significantly different between years（Chi square=296.687，P0.01）. Compared with female perinatal death (9.20‰)

the male was slightly lower (8.96‰). The PMRs in three monitored groups

i.e.20-year-old puerpera group

20~35 puerpera group and ≥35-year-old puerpera group

were 14.17‰

7.96‰ and 16.25‰

respectively. The top 5 causes of perinatal death were birth defects（29.78%）

complication of pregnancy（8.27%）

umbilical cord factors（6.48%）

preterm birth or low birth weight（4.39%） and placental factors（3.80%）. Conclusion      It is urgent to prevent birth defects

improve prenatal diagnosis technology

and strengthen the prenatal care service

which leads to reducing perinatal death.
