Prenatal maternal stressors linked to higher BP during first year after birth, study shows
Psychosocial stress during pregnancy could lead to higher blood pressure during the first year postpartum according to research from Keck School of Medicine of USC.
The study, published in Hypertension and supported by the National Institutes of Health, investigated whether mothers who reported higher perceived stress and depressive symptoms during pregnancy, developed higher blood pressure in the four-year period after birth. The findings showed higher stress and depressive symptoms during pregnancy were associated with greater blood pressure during the first year postpartum, but associations diminished thereafter.
“Pregnancy is a complex time where women experience different physiological changes,” says Noelle Pardo, the lead author of the study and third year doctoral student in the Department of Population and Public Health Sciences at Keck School of Medicine. “This study is building on maternal health research to understand how stressors impact women’s lives and their health after pregnancy.”
The study included data from 225 mothers from the MADRES pregnancy cohort which primarily consists of Hispanic women, and low-income participants living in Los Angeles. Hispanic women have a high burden of cardiovascular risk, and there is growing evidence linking psychosocial stressors to poor cardiovascular health, which is a leading cause of death among women in the US.
