| Maternal Mortality rate (MMR) is one of important markes , which weight the social economic strength , culture development and health care in the coutry or an area. The international social constitutions also think highly of the study of this territory progression. It is planed that MMR should descend half based on 1990's in<>,and continuous descend 1/4 based on 2000s' ratio in << Chinese women developing scheme in 1990s>> (2000 -2010). For analysis of change regulation on MMR and cause of death , 25 points were selected to monitor in Liaoning province in 1990. Now, all dead pregnant women between 1998 ~ 2003 year in Liaoning province were studied.Subjects and MethodsThe data come from report and audit on maternal mortality in Liaoning and the epidemiology cross sectional study is used.1. Subject objectPregnant and lying - in women who lived in Liaoning province for more than one year.2. Content2.1 Total amount of live births and maternal mortality in Liaoning. 2. 2 Causes of maternal mortality.2. 3 Maternal mortality region and human distribution. 2.4 Health care services in maternal mortality.3. Collection of data3. 1 Channel: to creat a center surrounding women and Children health care organizations at every level for statistics live birth and maternal death.3.2 Time and content of report: the date of live birth and maternal deathwas collected and reported every season by {live births and maternal mortality statement} and{ Maternal mortality information card}.3.3 Three levels audit of maternal death.4. Quality controlQuality control of three grades was done every year , that were county , municipal and province class respectiraly.Results1. Maternal mortality ratio: there are 405 maternal death in Liaoning province between 1998 -2003. Average MMR is 29.47/100 000. MMR decreased from 37.50/100 000 in 1998 to 25.01/100 000 in 2003 (P <0.05).2. Causes of maternal deathThe main causes of maternal deaths in succession were: amniotic fluid embolism, mortality rate is 7. 12/100 000;obstetric hemorrhage, mortality rate is 3.50/100 000 ; pregnancy induced hypertension, mortality rate is 3.02/100 000; heart diseases , mortality rate is 2.05/100 000 ; hepatic disease , mortality rate is 1.75/100000 .3. Health care measureMMR is 15. 33 times in no - health care in earlier period of Pregnancy and 8. 17 times in no - antenatal care . Mortality rate increased 1.61 times without gives birth to baby in hospitals .4. Demographic characteristics of maternal death25 ~30 years old is the most safe period to childbirth ,the death rate is 13. 05/100,000. Age in 30 ~ 35 years olds above 35 years old and lower than 20 years old mortality rate is 3. 34 times 6.92 times and 9. 82 times high than the first group respectively.Discussion1. Comparison of MMRMMR is the lowest in north Europe (0 -11/10 000) and the highest in Af-rican (1000/100 000) through the world. The developed countries were 27/100 000, The developing countries were 480/100 000. MMR in china is 43.20/100 000 in 2002 year and it is 19.70/100 000 in coastland. Therefore, MMR in Lia-oning is close to average level in developed countries, but Lower than that in prosper the region of domestic.2. Comparison of cause of deathThe main causes of maternal death according to WHO'S report that were obstetric , hemorrhage, infection, pregnanty induced hypertensional. In china that is obstetric hemorrhage, pregnancy induced hypertension and amniotic fluid embolism in 2002 year. That succession in Liaoning is amniotic fluid embolism , obstetric hemorrhage and pregnancy induced hypertension.3. The reason of maternal death declineTo enhance management, check high risk fators of gestation . To audit case of dath, and to extend the results of science research were the critical measures to decrease the MMR in Liaoning province.Conclusion1. The MMR of liaonig in 2003 year is 25.01/100 000. That is close to average level of deve...
