title: Studies on blood pressure during pregnancy. I. Influence of parity and age.
abstract: Routine prenatal visit blood pressure measurements were used to examine the differences in blood pressure by age and parity in a cohort of 6,662 white gravidas. Both age and parity were observed to have significant effects on blood pressure during pregnancy. For a given age, nulliparas were observed to have higher mean blood pressures than parous gravidas, irrespective of the inclusion or exclusion of gravidas who were diagnosed to have hypertensive disorders during their pregnancies.
