Childbirth experience, risk of PTSD and obstetric and neonatal outcomes according to antenatal classes attendance

Antenatal classes have evolved considerably and include now a discussion of the parents' birth plan. Respecting this plan normally results in a better childbirth experience, an important protective factor of post-traumatic stress disorder following childbirth (PTSD-FC). Antenatal class attendance may thus be associated with lower PTSD-FC rates. This cross-sectional study took place at a Swiss university hospital. All primiparous women who gave birth to singletons from 2018 to 2020 were invited to answer self-reported questionnaires. Data for childbirth experience, symptoms of PTSD-FC, neonatal, and obstetrical outcomes were compared between women who attended (AC) or not (NAC) antenatal classes. A total of 794/2876 (27.6%) women completed the online questionnaire. Antenatal class attendance was associated with a poorer childbirth experience (p = 0.03). When taking into account other significant predictors of childbirth experience, only induction of labor, use of forceps, emergency caesarean, and civil status remained in the final model of regression. Intrusion symptoms were more frequent in NAC group (M = 1.63 versus M = 1.11, p = 0.02). Antenatal class attendance, forceps, emergency caesarean, and hospitalisation in NICU remained significant predictors of intrusions for PTSD-FC. Use of epidural, obstetrical, and neonatal outcomes were similar for AC and NAC.
