More infants born extremely preterm (<28 weeks' gestation) or extremely low birthweight (<1000 g) are surviving into adulthood in recent years. Preterm adolescents have higher blood pressure (BP) than normal birthweight controls, but how their BP changes with increasing age is not known. We compared BP at 25 years and trajectories of BP (change per year) from 18 to 25 years between survivors born <28 weeks/2499 g) controls born in the early 1990s, when survival rates began to rise. Participants were derived from 297 consecutive survivors born <28 weeks/<1000 g in 1991 to 1992 in Victoria, Australia, and 260 contemporaneous controls. At age 25 years, ambulatory BP was measured in 151 and 119 ..
