[Analysis of related factors of premature delivery for the migrant population in local suburban Beijing areas].

ABSTRACT

OBJECTIVE: To study the health conditions of pregnant migrant women in some suburban areas of Beijing by comparing a variety of pathological, physiological and social factors and exploring the relevant factors associated with preterm birth so as to prevent effectively preterm birth. METHODS: A total of 279 cases of pregnancy in preterm birth at out hospital from January 2004 to December 2008 were reviewed. The date of maternal age, parity, prenatal examinations, history of vaginitis, history of chorioamnionitis, premature rupture of membranes, occupation, residing location and education status were recorded. And the relationship between them and preterm birth were analyzed by χ(2) test. RESULTS: The overall incidence of preterm birth was 5.34%. And the following factors had statistically significant differences with premature birth chorioamnionitis, vaginitis, premature rupture of membranes, a lack of prenatal examinations, low education status, migrant population or maternal parity. However there was no statistical significance (P > 0.05) between preterm birth and other factors, such as occupation. CONCLUSION: The incidence of preterm birth is associated with a lack of prenatal examinations, low education status, chorioamnionitis, bacterial vaginitis and premature rupture of membranes. Therefore the migrant women in Beijing should receive targeted education programs during pregnancy. And reproductive tract inflammation should be properly treated.
