Chahal et al. Respond to 'physical Exertion and Placental Abruption'

摘要

We appreciate the thoughtful comments by Baylin and Guyer (1) on our article, in which we evaluated the acute risk of placen-tal abruption following physical exertion (2). Their commentary raises important issues on the etiology of placental abruption, the clinical implications of our work, and the most appropriate public health message regarding physical activity during pregnancy.
