Surveillance of Hypertension Among Women of Reproductive Age: A Review of Existing Data Sources and Opportunities for Surveillance Before, During, and After Pregnancy.

Abstract

Hypertension is one of the largest modifiable risk factors for cardiovascular disease in the United States, and when it occurs during pregnancy, it can lead to serious risks for both the mother and child. There is currently no nationwide or state surveillance system that specifically monitors hypertension among women of reproductive age (WRA). We reviewed hypertension information available in the Behavioral Risk Factor Surveillance System (BRFSS), National Health and Nutrition Examination Survey (NHANES), National Health Interview Survey (NHIS), and Pregnancy Risk Assessment and Monitoring System (PRAMS) health surveys, the Health care Cost and Utilization Project administrative data sets (National Inpatient Sample, State Inpatient Databases, Nationwide Emergency Department Sample, and State Emergency Department Database and the Nationwide Readmissions Database), and the National Vital Statistics System. BRFSS, NHIS, and NHANES and administrative data sets have the capacity to segment nonpregnant WRA from pregnant women. PRAMS collects information on hypertension before and during pregnancy only among women with a live birth. Detailed information on hypertension in the postpartum period is lacking in the data sources that we reviewed. Enhanced data collection may improve opportunities to conduct surveillance of hypertension among WRA.
