Assessing the Impact of Social Factors on Survival Among Infants Born with Transposition of the Great Arteries, Tetralogy of Fallot, and Diaphragmatic Hernia in Texas, 2011–2019
摘要
Social factors impact survival for infants with birth defects. This analysis describes the impact of social factors on one-year survival for infants with congenital diaphragmatic hernia (CDH), transposition of the great arteries (TGA), and tetralogy of Fallot (TOF).
MethodsSurvival estimates were generated using the Kaplan-Meier method and the log-rank test with 0.05 significance stratified by social factors for infants born 2011–2019 with CDH (N = 942), TGA (N = 1,102), or TOF (N = 1,545). Crude hazard ratios (HR) and adjusted hazard ratios (AHR) with 95% confidence intervals (CI) were calculated for infant death using the Cox proportional hazards models.
ResultsOne-year survival was 88.7% for TOF, 88.0% for TGA, and 72.7% for CDH. Infants with CDH whose mother resided along the Texas-Mexico border had an increased risk of death compared to non-border residents (HR = 1.68, p =.003). Lower maternal education attainment was associated with increased risk of death for infants with TGA (HR = 1.75, p =.002) or TOF (HR = 1.54, p =.005) compared to infants whose mother had more than a high school education. Maternal Hispanic ethnicity increased the risk of death for infants with TGA (HR = 1.75, p =.005) or TOF (HR = 1.74, p =.002) compared to NH White infants.
DiscussionHispanic maternal ethnicity, lower maternal educational attainment, and residence along the Texas-Mexico border negatively impact infant one-year survival.
