Prenatal maternal stressors linked to higher BP during first year after birth, study shows

In addition to prenatal psychosocial stress, Pardo explored whether prenatal neighborhood social cohesion was a protective factor for postpartum hypertension risk-a first investigation of its kind. This refers to the sense of connection and trust a pregnant woman experiences in her community. According to her findings, social structures that promoted cohesion may have had a positive influence throughout pregnancy into the postpartum period and were associated with lower blood pressure.

“We chose social cohesion as a variable to understand how connected the participants felt to their community. Right now, there aren’t many programs or policies that help foster cohesion, yet such interventions may serve as a novel protective factor,” she says.

According to Pardo, maternal health research has mostly focused on pregnancy outcomes, with limited studies investigating the mother’s health after birth. Yet, her results have shown how crucial this research is in identifying conditions rooted in pregnancy.

The real-world application of this study calls for the identification of vulnerable individuals in the pregnant population, offering interventions to reduce stress and depressive symptoms. Similarly, it emphasizes the importance of monitoring women’s health after birth, through the provision of additional hypertension screenings among mothers who experience higher prenatal stress.

“Pregnancy may be important in determining a woman’s long term cardiovascular health. Similarly, more research is needed to determine how different exposures during pregnancy can convey future cardiovascular risk to women,” she concludes.
