Young Maternal Age at Childbearing and Delivery Discharge Contraception Choice [ID 1072]

INTRODUCTION: Short interpregnancy interval among young mothers is associated with adverse maternal and fetal outcomes. To better understand patient preferences and areas for intervention, we investigate the uptake of contraception and contraception type at delivery discharge across maternal ages in a high-risk, inner-city sample. METHODS: Between September 2020 and March 2022, we collected background demographics, obstetric outcomes, and contraception choice at delivery discharge from electronic medical records. Contraception option at delivery discharge was examined as both any contraception versus none and long-acting reversible contraception (LARC) versus other. Maternal age at delivery was grouped into less than 8, 19–24, 25–34 (reference), and greater than 35 years. Multivariable logistic regression was used to predict contraceptive choice by maternal age. RESULTS: In our sample of 3,644, 3.8% (n=136) were 18 years old or younger, 54.6% (n=1,951) Black race, and 73.6% (n=2,683) used public health insurance. Univariate analyses showed that younger age was associated with being Black, Hispanic, publicly insured, not in a long-term partnership, and less likely to have delivered via cesarean. The youngest- and oldest-aged mothers were more likely to be discharged with pharmacological contraception (X 2 (3)=13.34, P <.01). In multivariable logistic regression, odds for LARC remained elevated for the youngest (odds ratio [OR] 1.35; 95% CI, 0.89–2.05) and oldest (OR 1.48; 95% CI, 1.21–1.80) mothers while controlling for several important measured covariates. CONCLUSIONS/IMPLICATIONS: Maternal age predicts contraception uptake, and LARC uptake in particular, in this high-risk sample. Future research will examine duration of contraception and implications on interpregnancy interval, especially in the youngest mothers.
