Oregon PRAMS Project Summary/Abstract Oregon’s Pregnancy Risk Assessment Monitoring System (PRAMS) conducts surveillance on selected maternal behaviors and experiences that occur prior to, during and shortly after pregnancy. Because of the design of the survey, weighting which includes an emphasis on gathering data equitably from six racial and ethnic subpopulations, and a high response rate, the PRAMS surveillance data are very high quality and offer far more breadth and depth than birth certificate data. The Oregon Maternal and Child Health Section has also leveraged PRAMS into a longitudinal data collection system by re-interviewing respondents when the index child is 3 years old via the Early Childhood Health in Oregon survey. The PRAMS+ECHO surveillance system provides data for Oregon's Needs Assessments (including Title V and Home Visiting), for monitoring the health status of Oregon women and children, for informing state and local public health department program and policy efforts, and for research into emerging health problems and public health practice. The data have recently been used to monitor maternal mental health during and after pregnancy, safe to sleep/back to sleep habits, breastfeeding, maternal substance use during pregnancy (alcohol, commercial tobacco, e-cigarette, marijuana, and prescription painkillers), maternal leave employment practices, and periconceptional folic acid.
