Three different things get called birth trauma

A negative experience, a birth felt as traumatic, and diagnosable PTSD are three separate measurements with very different numbers.

These three get collapsed into one another constantly, and the numbers are not interchangeable.

1. A negative birth experience. Roughly 7% to 12% of women in general populations. Sweden, asked a full year later: 7%. Canada, national survey: 9.3%. Iceland, women having a first baby with no interventions: 11.5%, rising to 39.5% with three or more.

2. A birth experienced as traumatic. Much commoner and much more variable. A systematic review states: Between 9 and 44% of women experience giving birth as traumatic, and 3% of women develop a post-traumatic stress disorder following childbirth. In one Irish maternity hospital, 1,154 women were asked before discharge, and 18% (209 women) said their birth had been traumatic.

3. Childbirth-related PTSD, by diagnostic criteria. Two independent meta-analyses, different teams and different rules, land in the same place.

Population	Meta-analysis of 59 studies (24,267 women), postpartum rows from the 28 postpartum studies in it	Second meta-analysis
Community samples, after birth	4.0% (95% CI 2.77 to 5.71)	3.1%
High-risk groups, after birth	18.5% (95% CI 10.6 to 30.38)	15.7%

Same diagnosis, different starting point

Individual studies before pooling ranged from 1% to 30%, which is why two independent analyses converging matters more than either one alone.

The gap between feeling it and being diagnosed. In the Irish study, of the 209 women who called their birth traumatic, 134 completed a birth trauma scale at 6 to 12 weeks. Six of those 134, about 4%, reached the threshold for postpartum PTSD. The authors summarised it: The majority of women were resilient to birth trauma, few developed PTSD, but a larger cohort had significant functional impairment associated with sub-clinical postpartum PTSD symptoms.

Do not read the small diagnosis rate as reassurance about the restMost women who describe their birth as traumatic will not meet diagnostic criteria for PTSD. That does not mean they are fine. The middle group, distressed and impaired but below the diagnostic line, is the largest of the three, and it is the group least likely to be asked about. The specialist literature notes there are gaps in the evidence on how, when and who to screen.

Say this out loud, at your postpartum visit

"Something about the birth is still with me. Can we talk about it?"

"I am not asking whether I have a diagnosis. I am asking what help exists."
