What is PedNSS/PNSS?
What is PNSS?
The Pregnancy Nutrition Surveillance System (PNSS) is a program-based
public health surveillance system that monitors risk factors associated
with infant mortality and poor birth outcomes among low-income pregnant
women who participate in federally funded public health programs.
Data Sources
PNSS
uses existing data from the following public health programs for nutrition
surveillance:
- Special Supplemental Nutrition Program for Women, Infants and
Children (WIC);
- Title V Maternal and Child Health Program (MCH)
A majority of the data are from the WIC program that serves pregnant,
breastfeeding, and postpartum women.
Data Collection
Data on maternal health indicators
include pre-pregnancy weight status, maternal weight gain, parity,
interpregnancy intervals, anemia, diabetes and hypertension during
pregnancy. Data on maternal behavioral indicators include medical care, WIC
enrollment, multivitamin consumption, smoking and drinking.
Surveillance Reports
Data on infant
health indicators include birthweight, preterm births, full term low
birthweight and breastfeeding initiation. The PNSS provides nutrition
surveillance reports for the nation defined as “all participating
contributors” as well as for each contributor. A contributor may be a
state, U.S. territory, or a tribal government. Each contributor can receive
more specific reports by clinic, county, local agency, region, or
metropolitan area.
The goal of PNSS is to collect, analyze, interpret, and disseminate data
to guide public health policy and action. PNSS information is used for
priority setting and the planning, implementing, monitoring, and evaluating of public
health programs. The components of public health surveillance and
resulting public health action include:
