PRAMS is the Pregnancy Risk Assessment Monitoring System. It is a joint research project between the state departments of health and the Centers for Disease Control and Prevention, Division of Reproductive Health. The PRAMS Analytic Research File contains a standard set of variables enumerated in the PRAMS Research Dataset Codebook. The PRAMS data set includes five categories of the following variables: Birth Certificate Variables: Selected variables from the birth certificate file are included in the data set; information on maternal and infant demographics are primarily from this source. Questionnaire Variables: This is the information collected from the PRAMS survey. Analytic Variables: These are precalculated variables that combine different variables in the data set, often those that are restricted (e.g., body mass index [BMI] created by combining variables on maternal weight and height). Operational Variables: These variables come from the data collection process (e.g., mode the questionnaire was answered by mail or phone). Weighting Variables: These variables account for the PRAMS survey design and the statistical weighting of the data. These variables are needed to analyze PRAMS data by using complex sample software.
