title: [A case-control mortality study of migrant pregnant women in Zhejiang province].
abstract: OBJECTIVE
  To explore the mortality factors of migrant pregnant women and learn the healthcare utilization status to provide efficient interventions.
  
  
  METHODS
  A case-control study was conducted in Zhejiang province with a case-control ratio of 1: 4. Cases included migrant pregnant women who died. And controls were migrant pregnant women who survived and matched with single birth, age, hospital and gestational weeks. A questionnaire was used to survey social and demographic factors, healthcare status during antenatal or postpartum period and delivery conditions, etc.
  
  
  RESULTS
  Seventy-two cases and 288 controls were recruited. There were significant differences in socio-demographic, antenatal care and obstetric complications between two groups (P < 0.05). No prenatal examination was an important factor affecting maternal mortality by multivariate conditional Logistic regression.
  
  
  CONCLUSIONS
  Prenatal examination is an important influencing factor of maternal mortality. And improving the ability of utilizing health care system is an efficient method of lowering the migrant maternal mortality.
