The 1994 study of WIC program and participant characteristics (PC94), like the 1992 study (PC92), is substantially different from earlier efforts to collect data on WIC participants. PC94 employs the prototype reporting system which was developed by FNS for the 1992 study and which routinizes the collection of participant information from state WIC agencies. 

This study is an analysis of very low birthweight among Medicaid newborns and the effect of prenatal WIC participation on the likelihood of very low birthweight.
