Adrenal function links to early postnatal growth and blood pressure at age 6 in children born extremely preterm

For term-born infants, low birth weight has been shown to correlate with a broad array of adverse cardiometabolic outcomes, and excess glucocorticoid exposure has been linked to these relationships. Also, intra-uterine growth restriction (IUGR) in term-born infants has been linked to subsequent increases in adrenal androgen activity. In this episode, we meet Kristi Watterberg, a professor of Pediatrics at the University of New Mexico who evaluated the relationship between preterm birth to salivary cortisol and dehydroepiandrosterone (DHEA) at age 6, and assessed the relationship of cortisol and DHEA with blood pressure and measures of adiposity. The results suggest interventions to improve the cardiometabolic outcomes of infants born extremely preterm.
