Abstract: Objective To ascertain perinatal mortality in Yongkang City and provide a basis for establishment of maternal health management system. Methods A retrospective study was made to analyze the perinatal mortality rate in 2006.10-2011.9 in Yongkang City, and the clinical data were statistically analyzed between the local and migrant populations. Results In 2007-2011, the perinatal mortality rate of migration was decreasing year by year. But the average perinatal mortality rate in 2007-2011 in Yongkang City was 21.97‰ for migration and 6.78‰ for local population. The perinatal mortality rate in migrant population was significantly higher than that in the local population (P<0.01). Because of fetus factor, undefined disease, mother factor or placenta factor, the perinatal death rate was much higher in migrant population than in local population(P<0.05). The perinatal healthcare service quality in migrant population was significantly lower than in local population(P<0.01). Conclusion Although the perinatal mortality in migrant population showed an obvious decline in the past 5 years, it was still significantly higher than that in the local population. The coverage rate of systematic perinatal healthcare was low in migrant population. It is necessary to take measures to strengthen the management of perinatal healthcare for migrant population and strengthen health education to improve self protection. It is also necessary to freely provide basic perinatal healthcare service for destitute migration and decrease the perinatal mortality in migrant population.
