Abstract
Background
The preterm birth rate among infants with trisomy 21 is more than twice the rate among the general population. Maternal hypertension and diabetes are established risk factors for preterm birth in the general population; however, their impact on pregnancies of infants with trisomy 21 is unknown. This study aimed to evaluate the association between maternal hypertensive disorders/diabetes and preterm birth among infants with trisomy 21.
Methods
We utilized data from the Texas Birth Defects Registry for deliveries between 1999 and 2018 (n = 9355). We conducted Poisson regression to estimate crude and adjusted risk ratios for preterm birth associated with any maternal hypertension and any diabetes, and their subtypes (pregestational, gestational). We also evaluated the risk associated with exposure to both (co-occurring) conditions compared to neither. Stratified analyses were conducted by racial/ethnic subgroups, preterm subtypes (< 32 weeks and 32–36 weeks), and presence/absence of congenital heart defects as part of secondary analyses.
Results
We found that maternal hypertension and diabetes were associated with 50% and 21% higher risk for preterm birth, respectively, while the presence of both conditions versus neither was associated with a 71% higher risk. The association with hypertension was much stronger for delivery at < 32 weeks aRR 2.60 (95% CI 1.83, 3.70) than for delivery at 32–36 weeks aRR 1.46 (95% CI 1.28, 1.66).
Conclusions
Our findings shed light on the role of maternal hypertension and diabetes in preterm birth risk among infants with trisomy 21, particularly when both conditions co-occur and for extremely to very preterm birth.
期刊介绍:
The journal Birth Defects Research publishes original research and reviews in areas related to the etiology of adverse developmental and reproductive outcome. In particular the journal is devoted to the publication of original scientific research that contributes to the understanding of the biology of embryonic development and the prenatal causative factors and mechanisms leading to adverse pregnancy outcomes, namely structural and functional birth defects, pregnancy loss, postnatal functional defects in the human population, and to the identification of prenatal factors and biological mechanisms that reduce these risks.
Adverse reproductive and developmental outcomes may have genetic, environmental, nutritional or epigenetic causes. Accordingly, the journal Birth Defects Research takes an integrated, multidisciplinary approach in its organization and publication strategy. The journal Birth Defects Research contains separate sections for clinical and molecular teratology, developmental and reproductive toxicology, and reviews in developmental biology to acknowledge and accommodate the integrative nature of research in this field. Each section has a dedicated editor who is a leader in his/her field and who has full editorial authority in his/her area.
