Maternal and Neonatal Outcomes of Adolescent Pregnancies in the Military Health System.

OBJECTIVE

To determine if universal access to care for military beneficiaries improves timing of presentation to prenatal care (PNC) in adolescent and young adult (AYA) pregnancies, improving maternal and neonatal outcomes.

STUDY

DESIGN

Retrospective descriptive cohort study, which assessed PNC initiation in eligible military beneficiaries: dependent daughters, active-duty women, and active-duty spouses aged 13 to 26 between January 2015 and December 2019, and subsequent adverse maternal and neonatal outcomes.

RESULTS

The cohort included 4,557 eligible pregnancies and 4,044 mothers aged 13 to 26. Late entry to PNC was not associated with gestational diabetes, prolonged rupture of membranes, pregnancy loss, elective abortion, substance use, or premature labor. Younger age was significantly associated with substance use, elective abortion, and sexually transmitted infection. There were 2,107 eligible newborns. There was no significant difference in gestational age at birth, incidence of prematurity, birthweight percentile, or occurrence of a neonatal intensive care unit admission based on maternal age. In comparison to published national outcomes, there was a significantly smaller occurrence of preterm (5.3% vs. 9.57-10.23%, 95% CI, 4.4-6.4%), small for gestational age (5.2% vs. 10-13%, 95% CI, 4.3-6.2%), and large for gestational age (4.8% vs. 9%, 95% CI, 4.0-5.8%) births, but a higher occurrence of neonatal intensive care unit admissions (16.9% vs. 7.8-14.4%, 95% CI, 15.4-18.6%) in infants born to military beneficiaries.

CONCLUSIONS

Our findings suggest that expanded universal access to health care may improve AYA pregnancy and delivery outcomes. Infants born to AYA military beneficiaries have improved neonatal outcomes compared to nationally published data. These results may correlate to improved maternal access within a free or low-cost healthcare system.
