Public Health Data Inventory

Pregnancy Nutrition Surveillance System


The Pregnancy Nutrition Surveillance System (PNSS) is a national program-based public health surveillance system that monitors risk factors associated with infant mortality and poor birth outcomes among low-income pregnant women that participate in federally funded public health programs. In Nebraska, all of the data are collected through the Nebraska WIC Program in coordination with the Centers for Disease Control and Prevention (CDC). WIC state and local agencies utilize PNSS information to: Identify priority areas for education and targeting of services; monitor progress toward program objectives; and evaluate program effectiveness.

Type of Data

The data are program level for ongoing surveillance.

Data Collection Method and Availability

During the prenatal clinic visit, demographic and maternal health and behavioral data are collected and at the postpartum clinic visit, infant health data describing the birth outcome are obtained. Each woman contributes one record representing one pregnancy. The PNSS record that includes both prenatal and postpartum data is collected in the clinic and aggregated at the contributor or state level and then submitted to CDC on a quarterly basis. PNSS data have been collected annually since 1983. In 2012, CDC discontinued the Pregnancy Nutrition Surveillance System. The final data year available is 2011. Historical data are available from the data contact.
