“…This finding is similar to results from a longitudinal study that examined the association between trajectories of ambulatory blood pressure in a sample of pregnant adolescents (i.e. age 14–20 years) and showed that a subtle U-shape blood pressure trajectory was associated with birth at 39 weeks of gestation [26].…”

Background: Research has revealed group-level differences in maternal blood pressure trajectories across pregnancy. These trajectories are typically constructed using clinical blood pressure data and multivariate statistical methods that are prone to bias and ignore the functional, dynamic process underlying a single blood pressure observation. The aim of this study was to use functional data analysis to explore blood pressure variation across pregnancy, and multivariate methods to examine whether trajectories are related to gestational age at birth. Methods: Clinical blood pressure observations were available from 370 women who participated in a longitudinal pregnancy cohort study conducted in Montreal, Quebec, Canada. Functional data analysis was used to smooth blood pressure data and then to conduct a functional principal component analysis to examine predominant modes of variation.Results: Three eigenfunctions explained greater than 95% of the total variance in blood pressure. The first accounted for approximately 80% of the variance and was characterized by a prolonged-decrease trajectory in blood pressure; the second explained 10% of the variance and captured a late-increase trajectory; and the third accounted for approximately 7% of the variance and captured a mid-decrease trajectory. The prolongeddecrease trajectory of blood pressure was associated with older, and late-increase with younger gestational age at birth. Conclusion:Functional data analysis is a useful method to model repeated maternal blood pressure observations and many other time-related cardiovascular processes. Results add to previous research investigating blood pressure trajectories across pregnancy through identification of additional, potentially clinically important modes of variation that are associated with gestational age at birth.

Maternal History of Adverse Childhood Experiences and Ambulatory Blood Pressure in Pregnancy

Objective This study aimed to study the association between maternal history of childhood adversity and blood pressure in pregnancy. Methods A total of 127 pregnant women completed measures of adverse childhood experiences (ACE) and prenatal stress between June 2015 and April 2019. At 11 weeks’ gestation (range, 6–17 weeks), we measured 24-hour ambulatory blood pressure. All women were considered to be at risk for pregnancy complications due to elevated body mass index and self-reporting snoring in pregnancy. Results Women were, on average, 30 years old (range, 19–40 years), and average (standard deviation) body mass index in this sample was 34 (7) kg/m2 (range, 27–55 kg/m2). Higher ACE scores were associated with higher nighttime blood pressure (systolic blood pressure: β = 0.23, p = .013; diastolic blood pressure: β = 0.22, p = .028). There were no significant associations between the ACE score and daytime blood pressure. Women with four or more ACEs were more likely to display nocturnal blood pressure nondipping (odds ratio = 3.97, 95% confidence interval = 1.38–11.40). Associations between ACE and nocturnal blood pressure remained significant after adjusting for symptoms of prenatal stress. Conclusions Results indicate that experiences of childhood adversity are associated with elevated nocturnal blood pressure and loss of a typical decline in blood pressure between day and night.
