ObjectiveTo analyze the situation and causes of perinatal death in floating population in Wenzhou of Zhejiang province, and provide evidence for the reduction of perinatal mortality.

MethodsThe surveillance data of perinatal deaths in Wenzhou and the reports of children and maternal health condition in floating population were collected from 2007 to 2016 for analysis of the incidence trend, characteristics and causes of perinatal deaths.

ResultsThe perinatal mortality rate in floating population was significantly higher than that in local population (χ²＝143.832, P＜0.001). Moreover, it was noticed that the health care awareness and perinatal health care coverage in floating population were obviously lower than those in local population (χ²＝538.904, P＜0.001). The incidence of birth defect in perinatal death in floating population was obviously lower than that in local population (χ²＝53.291, P＜0.001). With the incidences of gestational hypertension related to dead fetus, stillbirth and neonatal death in flowing population was higher than that in local population (χ²＝25.441, 15.104, 13.415, P＜0.001). Besides, the incidence of placental abruption related with stillbirth and neonatal death in flowing population was higher than that in local population (χ²＝65.146, P＜0.001; χ²＝7.657, P＜0.01). The incidence of prolapse of cord in dead fetus in floating population was higher than that in local population (χ²＝21.466, P＜0.001). The incidence of premature birth/low birth weight related to perinatal death in floating population was higher than that in local population (χ²＝147.932, P＜0.001).

ConclusionThe perinatal mortality rate in floating population showed a downward trend in the past 10 years. Therefore, it is necessary to strengthen health education, standardize pregnancy examination and improve high-risk management through multi sectoral cooperation to reduce perinatal death in floating population and improve population quality.
