The Illinois Pregnancy Risk Assessment Monitoring System (PRAMS) is an ongoing population-based survey of women who have recently delivered a live born infant in Illinois. PRAMS, located in the Illinois Center for Health Statistics, is an important part of the Illinois Department of Public Health’s surveillance activities and is part of a national initiative by the U.S. Centers for Disease Control and Prevention (CDC) to reduce infant morbidity and mortality. PRAMS collects information from mothers about their behaviors and experiences before, during and immediately after pregnancy. The unique information collected by the PRAMS program is used by health professionals, administrators, policy makers and researchers to develop and modify programs and policies to improve the health of women and children in Illinois. Currently, 37 states, New York City, and the South Dakota Tribal Collaborative project participate in PRAMS nationwide, representing about 75 percent of all U.S. births.
