Statistically adjusting for perceived stress, earlier gestational age at
birth was associated with a more prominent U-shaped systolic (a) and diastolic
(b) blood pressure trajectory over pregnancy. Gestational weeks were modeled
continuously. Here results of the model are shown, with 34, 37, 39, and 41 weeks
gestational age at birth selected based on criteria from Spong (2013) (42). 39 weeks gestational age birth was the
mean of the sample. These results indicate that a subtle U-shape may be
predictive of full term infants.
