CDC discontinued the Pediatric and Pregnancy Nutrition Surveillance Systems (PedNSS and PNSS) at the end of 2012. These program-based surveillance systems monitored the nutritional status of low-income infants, children, and women in federally funded maternal and child health programs. The most recent annual national PedNSS and PNSS data tables available on this website are for calendar year 2011.


What is PedNSS/PNSS?
What is PedNSS?

The Pediatric Nutrition Surveillance System (PedNSS) is a child-based public health surveillance system that describes the nutritional status of low-income U.S. children who attend federally-funded maternal and child health and nutrition programs. PedNSS provides data on the prevalence and trends of nutrition-related indicators.

Data Sources

PedNSS uses existing data from the following public health programs for nutrition surveillance:

  • Special Supplemental Nutrition Program for Women, Infants, and Children (WIC);
  • Early and Periodic Screening, Diagnosis, and Treatment (EPSDT) Program; and
  • Title V Maternal and Child Health Program (MCH).

A majority of the data are from the WIC program that serves children up to age 5.

Data Collection

Data on birthweight, short stature, underweight, overweight, anemia, and breastfeeding are collected for infants, children, and adolescents from birth to 20 years of age who go to public health clinics for routine care, nutrition education, and supplemental foods.

Surveillance Reports

The PedNSS 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 tribal government. Each contributor can receive more specific reports by clinic, county, local agency, region, or metropolitan area.


The goal of PedNSS is to collect, analyze, and disseminate data to guide public health policy and action. PedNSS information is used for priority setting and the planning, implementing, monitoring and evaluating specific public health programs.
