Cluster Randomized Controlled Trial of a Breathing and Relaxation Training Included in Antenatal Education

The study aimed to evaluate the effectiveness of the BreLax antenatal education class, which incorporates breathing and relaxation techniques, in enhancing childbirth self-efficacy compared to standard antenatal education. While both groups showed significant improvements in self-efficacy, the intervention group did not demonstrate superior outcomes, although increased practice of the techniques was linked to higher self-efficacy. The findings suggest that structured breathing and relaxation training can be beneficial, highlighting the need for further research on practice intensity and engagement methods.
