Childhood Maltreatment, Labor Duration, and Intrapartum Synthetic Oxytocin Dose and Duration: A Potential Oxytocin-Linked Contributor to Labor Outcomes in Black Birthing People.
Abby Britt, Melinda Higgins, Anne Dunlop and 2 others
PMID 40461950WHAT IT FOUND
In 109 Black birthing people, childhood maltreatment scores were not associated with labor duration or synthetic oxytocin dose and duration overall.
In the 47 induced labors, higher physical abuse scores were associated with longer labor and higher synthetic oxytocin dose and duration.
Key findings
01In the total sample of 109, labor duration was not significantly associated with total childhood maltreatment scores or with any maltreatment subscale.
02In the 47 induced-labor participants, labor duration was significantly associated with physical abuse scores, while emotional abuse showed a non-significant positive association.
03In the 47 induced-labor participants, physical abuse scores were significantly associated with higher total synthetic oxytocin dose, longer oxytocin duration, and higher mean dose per hour.

What it does not show
The analysis included only 109 people, and only 47 had induced labor, so subgroup findings are small. It was a secondary analysis of data collected for another purpose, not powered for these specific childhood maltreatment and labor questions. Participants reported low levels of childhood maltreatment overall. This left little variability in trauma scores. Findings may not generalize beyond Black birthing people in an urban Southeast setting, or beyond term vaginal singleton vertex births. Childhood maltreatment was measured by retrospective self-report, so recall and reporting bias may affect trauma scores. For spontaneous labor, the study could not capture labor duration before hospital admission, so absence of association there may be due to incomplete measurement. The study did not measure intrapartum provider type, doula or labor support, or biological oxytocin function. Associations do not show that childhood maltreatment caused longer labor or higher synthetic oxytocin use.

No conflicts of interest were declared. The article is categorized as having extramural NIH research support.
The easy way to misread this
Do not read these findings as proof that childhood maltreatment causes longer labor or higher synthetic oxytocin use. The study was observational, the total sample of 109 showed no significant associations, and the significant positive findings appeared only in the 47 induced labors.
