Hostility and anomie: links to preterm delivery subtypes and ambulatory blood pressure at mid-pregnancy.

Underlying maternal vascular disease has been implicated as one of several pathways contributing to preterm delivery (PTD) and psychosocial factors such as hostility, anomie, effortful coping, and mastery may be associated with PTD by affecting maternal vascular health. Using data from the Pregnancy Outcomes and Community Health (POUCH) study, we included 2018 non-Hispanic White and 743 African American women from 52 clinics in five Michigan, USA communities. Women were interviewed at 15-27 weeks' gestation and followed to delivery.
