Are maternal age, education, and race/ethnicity associated with the live birth prevalence of cyanotic congenital heart disease in U.S. births?
In U.S. live births, increasing maternal age is associated with higher odds of cyanotic congenital heart disease, whereas Latina ethnicity is associated with lower odds.
Cyanotic congenital heart disease (CCHD) remains a major contributor to infant morbidity and mortality in the United States, yet the influence of maternal social determinants of health on risk is not fully understood. This study examined associations of maternal age, education, and race/ethnicity with the live birth prevalence of CCHD using recent national birth data from the Centers for Disease Control and Prevention (CDC) National Vital Statistics System (2022–2023). CCHD was identified from birth certificate records and analyzed as a binary outcome. Regression analyses were performed to evaluate relationships between maternal characteristics and CCHD occurrence. Overall, CCHD was a rare outcome with a modest decline in prevalence between the two years examined. Increasing maternal age was associated with higher odds of CCHD, while Latina ethnicity was associated with lower odds compared to the reference group. Other racial/ethnic categories and maternal education level were not significantly associated with CCHD risk in adjusted analyses. These findings suggest that certain maternal factors, particularly age and ethnicity, are associated with variation in the live birth prevalence of CCHD and underscore the need for further research into underlying environmental and structural contributors not captured in standard birth records.
Reddy et al. (Sat,) conducted a observational in Cyanotic congenital heart disease (CCHD). Maternal characteristics (age, education, race/ethnicity) vs. Reference demographic groups was evaluated on Live birth prevalence of CCHD. Increasing maternal age was associated with higher odds of cyanotic congenital heart disease, while Latina ethnicity was associated with lower odds compared to the reference group.
