Physical Activity and Its Relationship with Preterm Birth in the Presence of Depressive Symptomology.

Objective: To examine the relationship between physical activity (PA) and preterm birth (PTB) within the context of depressive symptoms (DS).

Methods: Data are from the Life-course Influences of Fetal Environments (LIFE) Study, a cohort comprised of 1410 Black women, age 18-45 years who delivered a singleton in Metropolitan Detroit, MI. DS were measured with the Center for Epidemiologic Studies Depression Scale (CES-D); a score > 23 indicates severe DS.
