Stress During Pregnancy Associated with Newborn Low Birth Weight: Experiences from the State of Rhode Island.

PURPOSE: Prenatal stress is a known risk for poor birth outcomes. This study specifically looked at reported stress during pregnancy and low birth weight (LBW) in Rhode Island.

METHODS

Pregnancy Risk Assessment Monitoring System (PRAMS) data from 2016 to 2018 for the state of Rhode Island was utilized. Stress during most recent pregnancy was dichotomized as: 'none to minimal' and 'moderate to high.' LBW was defined as less than 2,500 g. Multivariable regression analysis was performed, accounting for complex survey design.

RESULTS

In this cohort, 24% of pregnant people reported moderate to high stress leading to an adjusted odds of 1.70 (95% CI 1.43-2.03) of having a LBW newborn compared to those with none to minimal stress. Primiparity, previous preterm birth, racism, smoking history, and history of chronic medical problems were also associated with LBW newborns.

CONCLUSION

We recommend screening and provision of support services for stress in all settings where pregnant people access care.
