Hypertension during follow-up of extremely preterm infants

Blood pressure data from a Swedish national population-based cohort of extremely preterm infants who survived were analyzed. At the age of 2.5 years 44% of the 68 extremely preterm infants had a systolic blood pressure at or above the 90th percentile, versus 23% of controls.  Boys had higher odds of high systolic blood pressure than girls. The slower the catch-up growth between 36 weeks post-menstrual age and 2.5 years, the higher the Z scores were for systolic and diastolic blood pressure.
