Adoption of these revised standards in pregnant women might allow earlier recognition of individuals at greater risk for complications. This approach holds particular promise for stratifying risk among first-time mothers. The present secondary analysis of the SCOPE cohort evaluated whether these ACC/AHA BP groupings could effectively highlight nulliparous women of standard risk who are predisposed to poorer pregnancy results. Participants were drawn from the international SCOPE cohort and included all pregnancies reaching 20 weeks’ gestation or beyond during the period 2004–2008. The majority of women were White, aged in their twenties, and possessed normal or elevated body mass index (BMI). Cases involving fetal demise prior to 20 weeks or pregnancy termination at any stage were omitted from the dataset.  Classification of participants relied on the maximum BP value observed throughout gestation, applying ACC/AHA definitions: normal (BP UR - https://galaxypub.co/article/evaluating-accaha-blood-pressure-categories-for-predicting-adverse-pregnancy-outcomes-in-nulliparou-bcvgq6tlwhc6tkf ER -
