Abstract:
Objective To analyze influential factors on maternal mortality by estimation on maternal mortality in China.Methods To estimate maternal mortality in China by maternal agespecific mortality curve and to analyze influential factors on maternal mortality with methods of correlation and regression.Results There is a high relation between estimating value and investigating value.There are apparent relations among the numbers of maternal and child station,unplanned birth rate,the situation of medical instruments in villages and maternal mortality.Conclusion The estimating model can estimate maternal mortality rapidly and accurately in developing countries and areas with uncompleted data,but related policy and living customs must be paid attention to in the course of estimation.
