Maternal Stressful Life Events Prior to Conception and the Impact on Infant Birth Weight in the United States

Abstract

This was the first nationally representative study to our knowledge to investigate the impact of PSLEs on very low and low birth weight in the United States. Interventions aimed to improve birth outcomes will need to shift the clinical practice paradigm upstream to the preconception period to reduce women's exposure to stress over the life course and improve the long-term health of children.
