The period before pregnancy is critically important for the health of a woman and her infant, yet not all women have access to health insurance during this time. Rebecca Myerson of the University of Wisconsin-Madison, Samuel Crawford of the University of Southern California, and Laura R.

Recent media reports have highlighted startling trends in U.S. maternal health with stark differences across racial and ethnic groups. Maternal deaths associated with pregnancy and childbirth are high when compared to other developed countries and have increased substantially over the last two decades.
