Domestic violence by a partner or ex-partner during pregnancy doubles the risk of pre-term birth and low birth weight, according to a study conducted by University of Iowa  researchers. The team also found that domestic violence slightly increased the risk of a baby being small for gestational age. The researchers  included first author Brittney Donovan, doctoral student in epidemiology, Audrey Saftlas, Cassie Spracklen, and Kelli Ryckman from the Department of Epidemiology, and Marin Schweitzer from the Department of Internal Medicine.
