Introduction. Participation in the Antenatal Classes allow future parents to consciously experience pregnancy and prepare for delivery, puerperium and later care for a newborn baby. Better and more conscious preparation seems to be beneficial for the laboring one, but also plays a significant role in communication with staff, reducing the duration of delivery. Aim. Analysis of the delivery process among patients attending antenatal classes compared to non-participants. Material and Methods. The study included 100 women who gave birth vaginally at term pregnancies. The methodology of the study consisted of the analysis of medical records and the collection of data using the forms filled in by a researcher. The studied population was divided into two groups: participating in the antenatal classes and non-participating ones The calculations were carried out using Stats Static software v 10.0 by Statsoft. The Pearson Chi square test was used to assess the dependence. The level of statistical significance was p ≤ 0,05. Results. In the group of women attending antenatal classes, 66% had higher education, 26% secondary and 8% vocational (p = 0.000002). Most of them (76%) used pain relief medication during labor. In the study group as many as 96% of women did not require epidural anesthesia. Among the participants of the School of childbirth, 66% had oxytocin-induced labor. More than a half (54%) of the participants of antenatal classes had no episiotomy, 24% had a first degree rupture of perineum, while 22% had an incision of that area. Conclusions. Participation in the antenatal classes seems to be dictated by the number of pregnancies and education. Pregnant women who completed such courses are much less likely to undergo antenatal procedures. They are more aware of the possibilities of pain management, the need to perform some of the procedures and the impact of the intrapartum course of delivery on the condition of their child.

Key words: antenatal classes, labor, education, pregnancy.
