Introduction

Data from the Pediatric Nutrition Surveillance System (PedNSS) can be used to describe the breastfeeding behavior among infants participating in public health programs. Using PedNSS data for the 2001 reporting year from a state WIC (Special Nutrition Program for Women, Infants, and Children) program, an epidemiological approach will be used to describe breastfeeding prevalence in terms of time, place and person by answering the following questions:

These questions will be answered based on the PedNSS outcomes of:

  • Percentage of infants ever breastfed
  • Percentage of infants breastfed at 6 months
  • Percentage of infants breastfed at 12 months

When using an epidemiologic approach, it is important to assess data quality before analyzing the data. For this example, assume that data quality is acceptable. The next step is to determine the extent of the health problem in the state WIC Program using PedNSS data tables.
