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.

 

PNSS Health Indicators

Data on maternal health and behavioral risk factors and infant birth outcomes are collected on low-income women who participate in federally funded public health programs. Maternal health indicators include prepregnancy weight status, maternal weight gain, parity, interpregnancy intervals, anemia, and diabetes and hypertension during pregnancy. The behavior risk factors assessed are medical care, WIC Program enrollment, multivitamin consumption, smoking and drinking. Birth outcome data includes birthweight, preterm births, full term low birthweight and breastfeeding initiation. PNSS health indicators are collected during prenatal and postpartum clinic visits to monitor the prevalence of nutrition and behavioral risk factors related to infant mortality and poor birth outcomes. The definition for each indicator and the rationale for collecting the indicator are described below:
