Incidence over 10% of premature deliveries in Hungary (based on the experience in Borsod-Abaúj-Zemplń County)

The incidence over 10% of premature delivery in Hungary was studied. The cause which motivated this work was the fact that despite of several preventive and therapeutic measures the incidence e.g. in BAZ county surpassed even the average of the country. Professors of clinics in different countries of Europe as well as medical societies dealing with this question have been consulted about the matter of whether it was sufficient to consider a neonate a premature infant and the delivery a premature one solely on the basis of birth weight (under 2.500 g). Data of BAZ county proved that this determination was misleading and proposals are made concerning the modification on the basis of the examinations of the authors.
