The aim of this randomised controlled trial is to compare the effects of an antenatal education class including a breathing and relaxation technique on self-efficacy compared to a standard antenatal education class without a focus on breathing and relaxation techniques.
Antenatal education classes were developed to inform expectant mothers about pregnancy, labour and birth and the postpartum period with the aim of improving pregnancy and childbirth experience. They were based, for example, on concepts of Lamaze and Grantly Dick-Read. Studies indicate positive emotional effects on labour and birth outcomes in women who attended antenatal education classes. This includes lower levels of fear of childbirth, lower rates of caesarean birth at the women's request, a higher rate of spontaneous births, and a stronger involvement of the partner, better chances of initiating breastfeeding, a lower likelihood of developing depression symptoms during the postpartum period. There is limited evidence on the link between birth preparation and neonatal outcomes. Considering recent evidence suggesting that antenatal education classes may positively influence maternal and neonatal birth outcomes, we intend to analyse an antenatal education class focusing on a breathing and relaxation technique and assess the impact of such a class on self-efficacy, as well as other maternal and neonatal birth outcomes.

An antenatal education class over 9 hours with information regarding pregnancy, labour and birth, pain management as well as the postpartum period with an integrated breathing and relaxation technique (prolonged exhalation in the individual rhythm) and 4 accompanying positions (standing upright, sitting supported, four-footed, supported lying on the side). In addition, participants receive a manual for independent practice at home.

Self-efficacy
Changes from baseline to after the antenatal education class measured with the german version of the childbirth self-efficacy inventory (CBSEI). The CBSEI is a 32-item scale that measures women's perceived self-efficacy towards labour. Items are scored on a scale of 1 to 10. A higher score indicates that participants are better able to cope with difficult tasks.
Time frame: 13 weeks till 37 weeks of pregnancy
Childbirth experience
Birth experience is assessed after birth using the german version of the childbirth experience questionnaire (CEQ 2.0) The CEQ 2.0 is a 25-item scale with four dimensions (own capacity, perceived safety, professional support and participation). Items are scored on a scale of 1 (disagree at all) to 4 (agree completely). A higher value indicates a more positive assessment of the birth experience.
Time frame: within 4 weeks after birth
pain management
epidural anesthesia (PDA) yes/no, nitrous oxide yes/no, Patient Controlled Analgesia (PCA) yes/no, other pain medication yes/no (medical birth record)
Time frame: within 4 weeks after birth
birthing position
Documented during labour and birth (medical birth record). elevated supine yes/no, lateral position yes/no, standing yes/no, 4-foot position yes/no, bathtub yes/no, sitting (stool) yes/no
Time frame: within 4 weeks after birth
Duration of labour
Documented during labour and birth (medical birth record)
Time frame: within 4 weeks after birth
Bonding
Documented during labour and birth (medical birth record). Direct skin contact after birth (Bonding) yes/no

5-minute Apgar-Score
Documented during labour and birth (medical birth record). Appearance 0 to 2 (pale/ trunk rosy, extremities pale/ rosy), Pulse 0 to 2 (no Puls/ \<100/min/ \>100/min), Grimace 0 to 2 (No/ Grimacing/ Screaming), Activity 0 to 2 (Flaccid/ Sluggish flexion movements/ Spontaneous good self-movement), Respiration 0 to 2 (None/ Slow, irregular breathing or gasping/ Regular (40/min)). Interpretation: normal: 9-10 points; marginal: 5-8 points; critical for the newborn: \<5 points.
Time frame: within 4 weeks after birth
arterial umbilical cord pH
Documented after labour and birth (medical birth record). Normal values in the umbilical artery blood are values of 7.20 - 7.38. At pH below 7.2 there is mild acidosis, below 7.1 moderate acidosis and below 7.0 severe acidosis.
Time frame: within 4 weeks after birth
Feasibility and effectiveness BreLax
Self-reported by participants (digital diary and questionnaire). How often practiced before birth (text), how long practiced each time (Text) , where practiced (Text) , when used during birth (contractions irregular yes/no, contractions regular yes/no, at end of birth (pushing phase) yes/no, whole birth) yes/no.
Time frame: 13 weeks of pregnancy till 4 weeks after birth
