Neighborhood Deprivation, Perceived Stress, and Pregnancy-Related Hypertension Phenotypes a Decade Following Pregnancy.

BACKGROUND

Hypertensive disorders in pregnancy and other adverse pregnancy outcomes (APOs) increase the risk of developing chronic hypertension and cardiovascular disease. Perceptions of stress and neighborhood context also influence blood pressure (BP) fluctuations. We examined if APOs, higher perceived stress, and neighborhood deprivation were associated with hypertension phenotypes a decade after pregnancy in untreated individuals.

METHODS

Participants were 360 individuals who gave birth between 2008 and 2009 and participated in a research study 8-10 years following pregnancy. Standardized office and home BP readings were obtained, and we applied the AHA/ACC 2017 guidelines to identify sustained, white coat, and masked hypertension phenotypes. We measured personal stress with the perceived stress scale and neighborhood deprivation with the CDC Social Vulnerability Index.

RESULTS

Of the 38.3% (138/360) with any hypertension, 26.1% (36/138) reported a diagnosis of hypertension but were currently untreated. Sustained hypertension was the most common (17.8%), followed by masked and white coat hypertension, both 10.3%. Hypertensive disorders in pregnancy were associated with sustained (odds ratio [OR] 5.54 [95% confidence interval, CI 2.46, 12.46] and white coat phenotypes (OR 4.20 [1.66, 10.60], but not masked hypertension (OR 1.74 [0.62, 4.90]). Giving birth to a small for gestational age infant was also associated with sustained hypertension. In covariate adjusted models, perceived stress, but not neighborhood deprivation, was significantly associated with masked hypertension.

CONCLUSIONS

A decade after delivery, APOs were associated with sustained and white coat hypertension, but not masked hypertension. Exploration of the mechanisms underlying, and clinical implications of, these associations is warranted.
