Background

The prevalence and risk factors of posttraumatic stress disorder after cesarean delivery, outside high-risk contexts, remain unclear.

Objective

This study aimed to assess posttraumatic stress disorder prevalence and risk factors at 2 months postpartum among a general population of women with cesarean delivery.

Study Design

This was a prospective ancillary cohort study of the Tranexamic Acid for Preventing Postpartum Hemorrhage after Cesarean Delivery (TRAAP2) trial, conducted in 27 French hospitals from 2018 to 2020, enrolling women expected to undergo cesarean delivery before or during labor at ≥34 weeks of gestation. After randomization, characteristics of the cesarean delivery and postpartum blood loss were prospectively collected. Two months after childbirth, posttraumatic stress disorder profile (presence of posttraumatic stress disorder symptoms) and provisional diagnosis (positive screening for diagnosis consistent with a posttraumatic stress disorder) were assessed by 2 self-administered questionnaires (Impact of Event Scale – Revised and Traumatic Event Scale). The corrected posttraumatic stress disorder prevalence was estimated with inverse probability weighting to take nonresponse into account. Associations between potential risk factors and posttraumatic stress disorder were analyzed by multivariate logistic or linear regression modeling according to the type of dependent variable.

Results

In total, 2785 of 4431 women returned the Impact of Event Scale – Revised questionnaire and 2792 the Traumatic Event Scale (response rates of 62.9% and 63.0%). The prevalence of posttraumatic stress disorder profile was 9.0% (95% confidence interval, 7.8%–10.3%) and of provisional diagnosis 1.7% (95% confidence interval, 1.2%–2.4%). Characteristics associated with a higher risk of posttraumatic stress disorder profile were prepregnancy vulnerability factors (young age, high body mass index, and African-born migrant) and cesarean delivery–related obstetrical factors (cesarean delivery after induced labor [adjusted odds ratio, 1.81; 95% confidence interval, 1.14–2.87], postpartum hemorrhage [adjusted odds ratio, 1.61; 95% confidence interval, 1.04–2.46] and high-intensity pain during the postpartum stay [adjusted odds ratio, 1.90; 95% confidence interval, 1.17–3.11]). Women who had immediate skin-to-skin contact with their newborn were at lower risk of posttraumatic stress disorder (adjusted odds ratio, 0.66; 95% confidence interval, 0.46–0.98), and women with bad memories of delivery on day 2 postpartum were at higher risk (adjusted odds ratio, 3.20; 95% confidence interval, 1.97–5.12). The Impact of Event Scale – Revised and the Traumatic Event Scale yielded consistent results.

Conclusion

Approximately 1 in 11 women with cesarean deliveries had posttraumatic stress disorder symptoms at 2 months postpartum. Some obstetrical interventions and components of cesarean delivery management may influence this risk.
