(677) Trends in Attempted Vaginal Delivery Among Triplet Gestations in the United States, 2014–2023

Wednesday, February 11, 2026
3:30 PM - 5:00 PM  
Objective:
 We sought to evaluate national trends in attempted vaginal delivery (VD) among triplet pregnancies in the US from 2014–2023. 

Study Design:
Using National Vital Statistics System data 2014-2023, we included triplet gestations ≥23 weeks. To ensure unique gestation-level representation, only the first-born infant of each set was analyzed. Trial of labor was defined as VD or trial of labor prior to cesarean delivery (CD). Trends in attempted VD during the study period were assessed using Joinpoint regression; measures of association were expressed as annual average percent change (AAPC) with 95% CI.

Results:
Of 32,772 triplet infants, 10,716 were first-born and had complete delivery data. Of these, 778 (7.3%) underwent trial of labor, with vaginal birth achieved in 385 (49.5%). Compared to those delivered by planned CD, those attempting VD were more likely to be publicly insured, identify as Black, and have higher education, greater parity, fewer co-morbidities, and earlier gestational age, Table 1. The rate of attempted vaginal delivery for triplet A increased over the study period, from 5.7% in 2014 to 8.4% in 2023 (AAPC 6.97%, 95% CI 1.3-12.8%), Figure 1.

Conclusion:
Attempted VD in triplet gestations increased significantly over the past decade. Further research is needed to determine whether maternal and neonatal outcomes vary by intended mode of delivery in this  high-risk population.
