Abstract

Few studies have examined disparities in adverse birth outcomes and compared contributing socioeconomic factors specifically between African-American and White teen mothers. This study examined intersections between neighborhood socioeconomic status (as defined by census-tract median household income), maternal age, and racial disparities in preterm birth (PTB) outcomes between African-American and White teen mothers in North Carolina. Using a linked dataset with state birth record data and socioeconomic information from the 2010 US Census, disparities in preterm birth outcomes for 16,472 teen mothers were examined through bivariate and multilevel analyses. African-American teens had significantly greater odds of PTB outcomes than White teens (OR = 1.38, 95% CI 1.21, 1.56). Racial disparities in PTB rates significantly varied by neighborhood income; PTB rates were 2.1 times higher for African-American teens in higher income neighborhoods compared to White teens in similar neighborhoods. Disparities in PTB did not vary significantly between teens younger than age 17 and teens ages 17-19, although the magnitude of racial disparities was larger between younger African-American and White teens. These results justify further investigations using intersectional frameworks to test the effects of racial status, neighborhood socioeconomic factors, and maternal age on birth outcome disparities among infants born to teen mothers.

Highlights

Disparities in birth outcomes among mothers in different racial, age, and socioeconomic groups continue to present a critical health concern in the United States
Infants born to African-American teens had a significantly greater proportion of preterm birth (PTB) than infants born to White teens (χ2 = 19.55, P < 0.05)
The observed proportion of PTB for African-American teens in high income neighborhoods was higher than both AfricanAmerican teens in lower and middle income groups and for White teen moms in all income groups

Summary

Introduction

Disparities in birth outcomes among mothers in different racial, age, and socioeconomic groups continue to present a critical health concern in the United States. Nationwide, AfricanAmerican mothers have a greater prevalence of adverse birth outcomes than White mothers [3], and previous studies have identified these racial disparities across all maternal age groups [4, 5]. The US consistently ranks behind other industrialized countries in infant mortality rates [11], and currently PTB is one of the leading causes of infant death overall in the US [3] Despite this critical nature of PTB, few studies have examined differences in PTB between African-American and White teen mothers.
