Data from the 
Pregnancy Nutrition
Surveillance System

Go directly to the data report for 2006 or 2007.

The Pregnancy Nutrition Surveillance System (PNSS) is a program-
based surveillance system that monitors the nutritional status of low-
income women in federally-funded maternal and child health programs.

Wisconsin has submitted data from the WIC Program to the Centers for Disease Control (CDC) for analysis and inclusion in PNSS since 1995. This surveillance data can be used for program planning, management and evaluation; for the development of health and nutrition interventions; and to monitor progress toward state and local health plans.  

The CDC website (exit DHS) provides information on PNSS and explains how to interpret the data.

PNSS Health Indicators

In Wisconsin, data collected on behavioral risk factors and infant birth outcomes are collected on women who participate in the WIC Program. PNSS indicators are collected during prenatal and postpartum clinic visits to monitor the prevalence of nutritional and behavioral risk factors related to infant mortality and poor birth outcomes.

The indicators collected are:

• pre-pregnancy BMI;

• maternal weight gain;

• anemia;

• parity;

• interpregnancy interval;

• medical care;

• WIC enrollment;

• smoking;

• smoking changes;

• smoking in the household;

• drinking;

• birth weight;

• pre-term birth;

• full-term low birth weight; and

• breastfeeding initiation.

The CDC website (exit DHS) defines the indicators and provides the rationale for collecting the information.
